摘要： PURPOSE: To reduce a difference between left and right blowout air temperature at the time of controlling a small flow rate in a heat exchanger for heating in which hot water flows only in one direction toward an upper hot water outlet side tank from a lower hot water inlet side tank. CONSTITUTION: A hot water distributing body 30c is integrally moulded on a connecting pipe 30 connected to a hot water inlet 3f of a heat exchanger 3 for heating, this hot water distributing body 30c is inserted into a hot water inlet side tank 3a, and hot water is made to flow into the hot water inlet side tank 3a from a hole 30e of the hot water distributing body 30c. In this way, it is possible to reduce a difference of left and right blowout air temperature by preventing short-circuit flow of hot water from the hot water inlet 3f toward a hot water outlet 3g by being influenced by its own buoyancy at the time of controlling a small flow rate.

摘要： PURPOSE: To make control of a minute rate of flow without providing any micro-opening. CONSTITUTION: The opening area of a hot water inlet pipe 19 to which hot water from an engine 1 flows in is throttled by a control flow-path 17a furnished in the valve body 17 of a flow control valve 4, while the opening area of a hot water inlet pipe 20 in communication to the inlet side of a heat-exchanger 3 for heating is throttled by another control flow-path 17b furnished in the valve body 17, and the middle part (i) between the two control flow-pashs 17a, 17b is put in communication always with 3 bypass circuit 5. Thereby the pressure in the middle part (i) is sunk, which enables sinking the pressure applied to the heat-exchanger 3 sufficiently, and thereby a minute rate of flow can be controlled in good performance even without setting any micro-opening by the valve body 17.

摘要： PURPOSE:To reduce necessary cooling capacity and to realize saving of a power. CONSTITUTION:A vaporizer 78 serving as a heat-exchanger is arranged in an air guide duct 70 and on the wake flow side of a blower fan 74 and a subcooler 3 serving as an auxiliary heat-exchanger is arranged on the wake flow side of a fan 14 for suction in a suction duct 62. Both the vaporizer 78 and the subcooler 3 are arranged in the same freezing cycle and since the same refrigerant flows therein, a refrigerant cooled in the subcooler 3 by means of suction cold air flows in the vaporizer 78 in the air guide duct and is used for heat-exchanger. Air-conditioned air discharged through a discharge port 72 toward a peripheral space is sucked through a suction port 60 disposed in an opposite position, whereby only the periphery of seated passenger is centralizedly air-conditioned by means of the air-conditioned air. Further, energy used for cooling is reduced to a freezing cycle. In the increase of temperature to a desired value, a relatively lower flow rate of a refrigerant suffices for a value necessary to a freezing cycle, and saving of a power can be achieved.

摘要： PURPOSE:To provide a heat pipe in which the heat transport control of the heat pipe becomes possible with a simple means and any malfunction is difficult to occur by filling the evaporating part of the heat pipe with a composition having an occlusive property for a working medium and discharging the working medium occuluded at a predetermined temperature. CONSTITUTION:A composition 2 having an occlusive property, sealed in the evaporating portion of the pipe 1 is generally used as a drying agent and is zeolite having a high affinity with water represented by a chemical formula of Na2O.Al2O.Al2O3.2SiO2.nH2 O, etc.). The composition 2 is sealed therein in weight approximately five times that of water which is a working medium. A wick 3 stuck over the entire surface of the side wall of the pipe 1 is constituted of a material capable of rapidly moving the working medium by utilizing a capillary phenomenon of a cloth or the like. Water which is used as a working medium receives an evaporation latent heat at the evapora tion portion 1a which is a high-temperature portion, and is evaporated, rising up within the pipe 1 and reaching a condensing portion 1b which is a low temperature portion, generating condensation latent heat to form water, flowing by the gravity and the capillary permeation of the wick and returning back to the evaporating portion 1a. Such operations are repeated and the transport of heat is conducted.

摘要： PURPOSE: To reduce fuel consumption of a water-cooled internal combustion engine, and promote exhaust gas purifying. CONSTITUTION: A heat accumulating tank 13 having a heat insulating structure, a flow control valve 6 and a heater core 4 for heating are arranged in a circuit on the cooling water outlet side of a water-cooled internal combustion engine 1, and when the engine is warmed up, the flow control valve 6 is set in a position where a passage to the heater core 4 for heating is fully opened. An air blower 5 for air-conditioning is stopped, and high temperature cooling water in the heat accumulating tank 13 is sucked in the engine 1 through an intake air heat exchanger 9 and oil heat exchangers 10 and 11 without radiating heat of the heater core 4. Therefore, engine intake air, engine lubricating oil and transmission actuating oil are effectively heated by the high temperature cooling water, and warming up is promoted. After the warming up finishes, opening of the flow control valve 6 is controlled according to an ordinary air- conditioning program, and the engine intake air, the engine lubricating oil and the transmission actuating oil are properly heated or cooled according to the seasons.

摘要： PURPOSE: To realize improvement in emissions and reduction in fuel consumption by providing an opening/closing valve for opening a bypass path in accordance with reduction of a load of an internal combustion engine, and providing a heat accumulator interposed in the bypass path. CONSTITUTION: A cooling water path 3 extended from a cooling water outlet 11 of an engine 1, leading to a radiator 2, is connected to a cooling water inlet 12 of the engine 1. A bypass main path 4 branches from the cooling water outlet 11 of the engine 1, to lead to a flow regulating valve 7, to extend bypass paths 41, 42. The one bypass path 41 is connected to a bottom wall of a heat accumulator 8 and here opened. During warming the engine, cooling water flowing out from the cooling water outlet 11, much flowing in the bypass path 41 from the bypass main path 4, is supplied to the heat accumulator 8. Cooling water of high temperature in the heat accumulator 8 is supplied to a water jacket and an oil warmer 14 via a warm water supply path 5 and the cooling water inlet 12. Thus by increasing a cylinder wall temperature of the engine 1, improving exhaust emission and reducing fuel consumption can be realized.

摘要： PURPOSE: To provide a regenerative heating and warming device for an automobile capable of providing a sufficient engine warming effect and an immediate heating effect in a car room immediately after starting an engine by way of forcibly regenerating and insulating high temperature cooling water at the time when the engine stops. CONSTITUTION: In the case when cooling water temperature in an engine 4 detected by a cooling water temperature sensor 56 rises up to 100 deg.C or more after delay time for two minutes passes when the engine 4 stops, cooling water which becomes higher than normal control water temperature of 85 deg.C by remaining heat of the engine 4 is forcibly taken in a heat insulating tank 27 and replaced with cooling water temperature of which is lowered in the heat insulating tank 27 by way of switching on a water pump 25 and switching over to a first cooling water channel by actuating a flow rate control valve 26. Consequently, even if the engine 4 is started after 24 hours pass at outside air temperature of 0 deg.C, cooling water temperature in the heat insulating tank 27 only goes down to 92 deg.C.
