摘要： PURPOSE:To obtain an efficient heat radiating fin by providing a fine core material extending vertically to a heating element and a heat radiating fin in the direction which crosses the core material at right angles, and making the collision area with cooling medium larger, the nearer it is to the heating element. CONSTITUTION:Some of a cooling medium flow flowing from above cools a first cooling fin 4 and some joins the main flow and flows to the second fin, and the residual flows out to the side. The more the fin 4 goes to the downstream, the larger the diameter of it is. Consequently, the cooling medium of the cool main stream which is not subjected to the effect of the temperature rise of an upper stream fin collides against each fin, and accordingly the cooling effect becomes extremely great. Since the heating element 1 is positioned below a bottom plate 2, the heat moves from bottom to top while being radiated. By this constitution, an efficient heat radiating fin can be obtained.

摘要： PURPOSE:To improve heat transfer performance and to enable reduction of the weight and the cost of a heat exchanger by a method wherein the angle of the central part of the fine piece of a heat transfer fin is increased to a value higher than those of both sides, and both sides parts except a portion in the vicinity of a central part are further divided to form composite fine pieces. CONSTITUTION:In a heat exchanger 3 for a vehicle air conditioner formed with a corrugated fin 1 and a transfer pipe 2, the corrugated fin 1 is formed with fine piece both sides 4 and 4' having composite chevron fine pieces 6-10 formed with a small fine piece, and a fine piece central part 5 having fundamental chevron fine pieces 6'-10' formed with a large fine piece. A crest angle theta2 of the fine piece central part is increased to a value higher than a crest angle theta1 of each of the fine piece both sides. In this constitution, since draft resistance of the central part 5 is increased and draft resistance of both sides 4 and 4' is decreased, a low air velocity part is formed at the central part 5 and high air velocity part on both sides 4 and 4'. Since the air velocity of both sides 4 and 4' having a high difference between an air tempera ture and a fin temperature can be increased, this constitution improves heat transfer efficiency, and enables reduction of the weight and the cost of the heat exchanger 3.

摘要： PURPOSE:To make the number of components less and an assembly regulation easier and a price lower, by fitting a radiation control sheet made up of a shape memorizing alloy sheet and a bias spring sheet put together, and controlling the quantity of radiation by opening/closing a louver according to temperature. CONSTITUTION:When a heat transmission surface temperature rises up, a shape memorizing alloy temperature is warmed by heat which has moved to a heat transmission surface 18, a shape memorizing alloy bottom plate portion 4, and further to the whole of a shape memorizing alloy 1 through the transmission of heat, and is heightened. With this, force which is generated when a metal formation within the shape memorizing alloy 1 changes from martensite to austenite, is induced in a direction where a louver is opened. And as the shape memorizing alloy temperature becomes higher, force becomes greater than the force of a bias spring 2 and the louver is opened, and the quantity of radiation becomes larger as the area of heat transmission has come to have equivalently increased enough for the area of a louver portion 3. Whereupon, the heat transmission surface temperature comes down, and the louver is closed. Accordingly, radiation quantity control sheets automatically increase/decrease the quantity of radiation by means of such action of louvers as above and can regulate fixedly the heat transmission surface temperature.

摘要： PURPOSE:To shorten the measurement time and to improve the measurement accuracy, by finding the absorptivity from the measured values in the stationary state of plural cases where the temperature of the whole device becomes stable, and calculating the radiation rate at optional temperature by using the measured values and absorptivity in the stationary state. CONSTITUTION:Various quantities are measured by a simultaneous measuring method as to two cases in the stationary state of high temperature to find the absorptivity -alphas. Then only the relation between the surface temperature Ts and radiation rate epsilon of a sample is measured while the measured absorptivity -alphas is constant. The radiation rate epsilon at the optional temperature is found from an equation I (where P is the heating value of a heater, S the intensity of artificial sunshine, A the surface area of the sample, sigma a Stefan-Boltzman constant, and Ts the temperature term of the sample surface temperature) based upon the various quantities measured in respective stationary states and the value of sample temperature may be large, so a measurement error is suppressed small relatively at room temperature which is high to some extent.

摘要： PURPOSE:To unify distribution of the velocity of the wide while remarkably improving radiation efficiency of a cooling fin by uniformly arranging cooling fins ranging over nearly the whole region of the circulation path of the cooling air. CONSTITUTION:Serrated small pieces 5-1-5-3 shifted from the serration-starting positions 5a-1-5a-3 form groups to be bent sideways downwards from the serration-starting positions 5a-1-5a-3 and these are turned up sideways at the bent parts 5c-1-5c-3 while shifting their positions respectively. As a result, the neighboring serrated small pieces 5-1-5-3 turning to the same direction hold a positional relation having a gap C1 between the serrated small pieces 5-1-5-2 while a gap C2 between the serrated small pieces 5-2-5-3 seen from the direction of the cooling air flow. The other serrated small pieces are also similarly formed. In this way, the cooling fins are uniformly arranged ranging over nearly the whole region of the cooling air circulation path thus unifying distribution of the velocity of the wind and remarkably improving radiation efficiency.

摘要： PURPOSE:To obtain a heat dissipation control device with high reliability such as an apparatus loaded in artificial satellite or the like by a structure wherein elastic spheres containing fluid heat transfer medium therein and interposed between an expansion container and a radiator plate. CONSTITUTION:Heat transfer medium 11 is a fluid made of single phase substance, which is excellent in heat conduction. In addition, three kinds of shape memory alloys 8, 9 and 10 have higher working temperatures in the order named. The heat transfer medium 11 excellent in heat conduction is encapsulated in elastic spheres 12. When an apparatus loaded develops heat and the temperature of a panel 2 rises, the temperature in an expansion container 14 also rises. When said temperature in the container 14 reaches the specified value, at first, a shape memory alloy spring 8 extends so as to press a contactor plate 5 against the elastic spheres 12. The heat in the expansion container 14 is transmitted in the order of the contactor plate 5, the elastic spheres 12 and a radiator plate 6 in order to be dissipated in cosmic space. In proportion to the further increase of the calofic value of the apparatus 1, the shape memory alloys 9 and 10 extend in the order named, resulting in making the elastic spheres 12 flatter and flatter and consequently the heat quantity to be conducted to the radiator plate 6 more and more. Thus, the quantity of heat dissipation increases in proportion to the calorific value of the apparatus 1, resulting in keeping the temperature in the apparatus 1 at the specified value.

摘要： PURPOSE:To accurately detect the dryness degree of a two-phase fluid, by arranging electrodes so that detection electrostatic capacity is not changed even if the flow mode of the two-phase fluid is changed. CONSTITUTION:Circular arc shaped electrodes 7a, 7b each having an appropriate length are arranged to the inner wall of a passage 1 comprising an insulating material through which a gas-liquid two-phase fluid mixture is flowed in opposed relation to each other so as to leave a gap 17 therebetween and a pair of electrodes 8a, 8b similar to a pair of said electrodes 7a, 7b are arranged so as to shift the positions thereof 90 deg.. By this constitution, even if a two-phase flowing state is not a perfect gas-liquid mixed phase stream and the flowing state thereof is changed, the relative positional relation between the shapes of the electrodes and the flowing state is not changed. Therefore, the measuring signal of electrostatic capacity is not changed and a stable measuring value is obtained.
