Patent number: 6397935Abstract: A flat type heat pipe for mounting a heating power element, which is capable of forming an optionally shaped heat transferring path with high accuracy, which is of a thin type and to which fins are easily attached. The flat type heat pipe includes at least two aluminum plates substantially in parallel with each other and brazed to each other so as to form a heat transferring path therebetween. The flat type heat pipe also includes an operating liquid which fills the heat transferring path. Because the heat transferring path 25 is formed by means of press molding, punching, laser beam machining, or cutting various shapes of heat transferring paths can be formed finely and with high accuracy. The flexible flat type heat pipe can be made thin, which allows for a variety of uses. Grooves and wicks can be disposed in the heat transferring path, thereby improving the heat conductivity. Because the surface is flat, the fins can be easily attached thereto, thereby a satisfactory radiation effect can be obtained.Type: GrantFiled: December 18, 1996Date of Patent: June 4, 2002Assignee: The Furukawa Electric Co.

Patent number: 6357517Abstract: A cooling apparatus includes a refrigerant tank having a surface to which heating devices are attached and containing liquid refrigerant which is boiled and evaporated by heat transferred from the heating devices, and a radiator for radiating the heat of the boiled and vaporized refrigerant. The radiator has an inflow return chamber provided with a small-diameter opening having a diameter smaller than that of the inflow return chamber. The liquid refrigerant of the gas-liquid mixed refrigerant is dammed by the small-diameter opening of the inflow return chamber and the dammed liquid refrigerant is returned through a return passage to the refrigerant tank. Since the liquid refrigerant contained in the gas-liquid mixed refrigerant is suppressed from flowing by means of the small-diameter opening, the gaseous refrigerant can transfer heat directly to the walls of the radiating passages, so that the deterioration of the radiating performance can be prevented.Type: GrantFiled: October 25, 1999Date of Patent: March 19, 2002Assignee: Denso CorporationInventors: Hiroyuki Osakabe, Kiyoshi Kawaguchi, Masahiko Suzuki, Shigeru Kadota

Patent number: 6352102Abstract: According to the present invention, in an air conditioning apparatus setting a double laminar mode in which inside air and outside air are blown while being partitioned, when the maximum heating state (including the high heating capacity close to the maximum heating operation) is set, a warm air bypass door for introducing warm air directly into a foot opening portion, without being mixed into cool air, functions as a movable partition member for partitioning an air passage at a downstream side of a heating heat exchanger, into an inside air passage and an outside air passage. In this way, it is possible to downsize the air conditioning unit.Type: GrantFiled: October 6, 1997Date of Patent: March 5, 2002Assignee: Denso CorporationInventors: Tetsuya Takechi, Toshihiko Muraki, Manabu Miyata, Hideaki Inazawa, Yasuhiro Sato, Koji Takahashi
