Patent number: 4955327Abstract: In a cooling apparatus for an engine, a water jacket is divided into two parts, namely a forcible circulation part located chiefly round a cylinder head, and a natural convection part located chiefly round a liner of a cylinder block. The natural convection part is filled at its upper space with a cooling water and at its lower space with a cooling medium different from the cooling water. The cooling medium has a boiling point around a temperature zone to cool the liner, and also has a specific gravity larger than that of the cooling water and immiscible with the cooling water.Type: GrantFiled: October 17, 1989Date of Patent: September 11, 1990Assignees: Mitsubishi Jidosha Kogyo Kabushiki Kaisha, Mitsubishi Denki Kabushiki KaishaInventors: Taizo Kitada, Takehiko Katsumoto, Osamu Hirako, Masatoshi Ninoyu, Yasuyuki Makigawa, Gorou Yamanaka, Masao Fujii

Patent number: 4775007Abstract: A heat exchanger comprises a plurality of regularly corrugated fins placed one over another in layers at regular pitches in a back-to-back arrangement so as to form alternate wide and narrow fluid passage between the adjacent corrugated fins, and each having a plurality of small through holes, a plurality of collars formed in a staggered arrangement, and an annular area not having any small through hole and formed so as to surround the root of each collar; and pipes for passing a secondary fluid therethrough, each inserted through the collars of the layers of the corrugated fins. The height of the collar from the lower surface of the annular area corresponds to the pitch between the adjacent corrugated fins, and thereby the corrugated fins can be assembled at regular pitches simply by placing one over another. The pipes are expanded after being inserted through the collars so that the pipes are firmly and closely joined to the collars for satisfactory heat transmission between the fins and the pipes.Type: GrantFiled: July 7, 1987Date of Patent: October 4, 1988Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kiyoshi Sakuma, Yoshiaki Tanimura, Hiroyuki Umemura, Makoto Yamada, Yu Seshimo, Masao Fujii, Ikuo Tsukamoto

Patent number: 4768583Abstract: A heat exchanger comprises a plurality of perforated and regularly corrugated heat transfer plates arranged in a ridge-to-ridge and furrow-to-furrow arrangement, so as to form primary fluid passages each consisting of alternate expanded sections and narrowed sections arranged along the direction of flow of a primary fluid, and a plurality of pipes for passing a secondary fluid therethrough, the pipes penetrating through and across the heat transfer plates. Oblique guide grooves are formed in the surfaces of each heat transfer plates to facilitate the downward flow of the condensate condensed over the surfaces of the heat transfer plates, the grooves being inclined closer to the vertical than to the horizontal to facilitate downward flow of any vapor condensed on the plates from the primary fluid whereby the heat transfer plates dry quickly for efficient heat exchange between the primary and secondary fluids.Type: GrantFiled: May 6, 1986Date of Patent: September 6, 1988Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Ikuo Tsukamoto, Kiyoshi Sakuma, Yoshiaki Tanimura, Hiroyuki Umemura, Yu Seshimo, Masao Fujii, Makoto Yamada

Patent number: 4653579Abstract: The boiling cooling apparatus is comprised of a heat generating device which is completely immersed in a liquid coolant which partially fills a sealed container. At least one vertically extending passage is provided through the heat producing device whereby ascending bubbles formed in the passage by the heat transfer from the heat generating device to the liquid medium cause an upward current flow through the passage. A plurality of current flow control plates are provided for diverting the upward flow of liquid coolant laterally and downwardly along the sides of the container to provide convection cooling of the liquid and directing the downward flow of liquid coolant into the lower end of the passage in the heat generating device to provide a cyclic flow of the cooling liquid.Type: GrantFiled: December 6, 1985Date of Patent: March 31, 1987Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Masao Fujii, Kazushige Nakao, Haruo Tetsuno

Patent number: 4500612Abstract: A temperature control device for a fuel cell has a heat exchanger piping sandwiched between a pair of temperature control plates in heat exchange relation therewith, said temperature control plates having reaction gas conduit means on surfaces opposite to confronting surfaces thereof. A circulation piping is adapted for circulation by a heat medium and is hermetically connected to an outside piping located outside of said temperature control plates for providing a closed piping system therewith. Said circulation piping contains sealed-in heat medium so that a portion of the inside space of the circulation piping is left for a gaseous phase of the heat medium. Heat exchanger means are provided to said outside piping to effect heat exchange with heat medium in said circulation piping.Type: GrantFiled: April 21, 1982Date of Patent: February 19, 1985Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Masao Fujii, Enju Nishiyama

Patent number: 4403676Abstract: A vehicle has two axially opposed driven wheels which are driven by two drive shafts of equal length, each flexibly drivingly coupled at its outer end to one of the wheels. A differential is located closer to a first one of the wheels and further from the other wheel. A short power output shaft extends from the differential towards the first wheel and is flexibly drivingly coupled at its outer end to the inner end of the drive shaft which drives that first wheel. A long power output shaft extends from the differential towards the other wheel and is flexibly coupled at its outer end to the inner end of the other one of the drive shafts, whose outer end is drivingly coupled to that other wheel. The long power output shaft passes through the inside space of a tubular housing, which is fixed at its inner end to the casing of the differential.Type: GrantFiled: July 1, 1981Date of Patent: September 13, 1983Assignee: Toyoto Jidosha Kabushiki KaishaInventors: Masao Fujii, Tetuo Hattori
