摘要： PROBLEM TO BE SOLVED: To provide a cooling device, having a wide range of applications by which path for coolant is improved for improving cooling performance and cooling temperature can be set approximately uniform in the whole area of heat receiving surface, which is in contact with a member to be cooled and cools the same by removing heat or can be set differently among parts of the area. SOLUTION: A cooling device 1 is formed by integrating several coolant paths 1a which are substantially U-shaped U and are comprised of outgoing paths 3a and return paths 3b through which coolant R flows in and out. The coolant paths 1a are arranged, in such a way that planes comprised of outgoing paths 3a and return paths 3b are approximately in parallel with each other. Also, at least one of the planes comprised of several going paths 3a and the plane comprised of several returning paths 3b functions as heat receiving surface C (2c, 3c and 4c).

摘要： PROBLEM TO BE SOLVED: To cool electronic components which generate a heat and utilize effectively a part of thermal energy emitting during cooling. SOLUTION: A cooling device 1A for electronic components is comprised of a radiating part 2, which is brought into contact with an electronic part 6, a cooling vessel 3 where a refrigerant R is fed and discharged, a thermoelectric element 4 which is inserted between the radiating part 2 and the cooling vessel 3 in a manner such that it is in contact with the surface 21 of the radiating part 2 and the outer surface 34 of the cooling vessel 3, and a heat transporting pipe 5A whose one end 50a is brought into contact with the radiating part 2 and the other end 52a with the cooling vessel 3 respectively. Thus, heat generating in the electronic components is emitted from the radiating part to the refrigerant in the cooling vessel 3 via the pipe 5A, so as to cool the electronic components, and at the same time, the thermoelectric element 4, which is given a high heat transmitted from the electronic components through the radiating part and a low heat transmitted from the refrigerant via the cooling vessel 3, generates an electric power thanks to the difference in temperatures between the high heat and low heat.

摘要： PURPOSE:To combine high strength with high toughness, in an as-cast state, in a non-heat treated type aluminum alloy casting. CONSTITUTION:The composition of a material is regulated so that it consists of, by weight, 3-5% Mg, 3-5% Zn, 0.3-1.0% Mn, 0.005-0.06% B, 0.05-0.8% of elements selected from the group consisting of Ti, Zr, Cr, and V, and the balance Al. A molten metal of this material is poured into a mold and then solidified and cast at a cooling rate where the maximum cooling rate between liquid phase and solid phase becomes (50 to 300) deg.C/sec. By this method, borides and intermetallic compounds are refined by rapid cooling and, as a result, alpha-Al phase is refined and the strengthening of entering into solid solution is accelerated, by which strength and toughness can be improved.

摘要： PURPOSE:To provide the composite material which is suppressed in the degradation in ductility and has excellent hardness by forming TiB2 in a stable state in the presence of molten Ti by a reaction process. CONSTITUTION:A heated melt in which a boride more unstable than the TiB2 is dissolved is formed from the raw materials of a TiAl intermetallic compd. and the boride and is solidified as it is. As a result, the TiB2 formed by the reaction is dispersed by 0.3 to 10vol.% into the TiAl-base composite material. The B diffused and fined by the dissolution of the boride is considered to crystallize or precipitate the TiB2 by reacting with Ti. Since the reaction to form the TiB2 is induced without segregation in the melt, the fine TiB2 is estimated to be formed uniformly in the TiAl intermetallic compd.
