Patent number: 6196168Abstract: The invention concerns a device and method for cooling and preheating, especially of transmission fluid, of an internal combustion engine, with an equalization tank, with at least one radiator, which can be connected by means of an engine thermostat when a predetermined temperature is reached in the cooling loop, and with a water/oil heat exchanger. It is prescribed according to the invention that the forward stream (1) of a single water/oil heat exchanger (5) be branched off in the heating phase by means of a valve unit (3) essentially from the main cooling loop (12) of the internal combustion engine (17) and that its forward stream (1) in the cooling phase be taken by means of the same valve unit (3) essentially in the coolant side stream (13) from the low-temperature region (14) of the radiator (4) or a separate low-temperature cooler (14a) connected in the side stream after radiator (4, 4a).Type: GrantFiled: August 13, 1998Date of Patent: March 6, 2001Assignees: Modine Manufacturing Company, Bayerische Motoren WerkeInventors: Winfried Eckerskorn, Axel Temmesfeld, Heinz Lemberger, Christian Absmeier, Gerhart Huemer, Victor Brost, Klaus Kalbacher, Karl Schütterle

Patent number: 5960872Abstract: In order to control the temperature of the transmission oil of a motor vehicle driven by a liquid-cooled engine, a coolant/transmission oil heat exchanger is provided. The coolant stream supplied to the heat exchanger is miscible in a thermostatic valve from recooled and non-recooled coolant in order to achieve a desired temperature. Preferably the thermostatic valve is controlled by the temperature of the transmission oil, but it is also possible to have two expanding material elements as control pistons of the thermostatic valve, with one control piston being provided in the oil chamber of the thermostatic valve and the other control piston being provided in the coolant mixing chamber of the thermostatic valve. It is also possible, for purposes of precontrol, to electrically heat at least one of the control pistons.Type: GrantFiled: February 3, 1997Date of Patent: October 5, 1999Assignees: Bayerische Motoren Werke Aktiengesellschaft, Modine Laengerer & Reich GmbHInventors: Gerhart Huemer, Heinz Lemberger, Winfrid Eckerskorn, Christian Absmeier, Axel Temmesfeld, Victor Brost, Karl Schuetterle, Klaus Kalbacher

Patent number: 5931228Abstract: According to a first aspect of the invention, a cooling module comprises a cooling system which comprises a radiator. A fan for generating air flow across the radiator also has a fan housing attached to the radiator in which the fan is located so that the fan is disposed relative to the radiator such that the fan may generate air flow across the radiator. A mounting plate is also attached to the radiator and has a first side facing the radiator and a second side. The mounting plate has attachment sites on the second side integral therewith on which other parts of the cooling system are mountable and channels integral therewith through which a coolant flowing through the cooling system may pass.Type: GrantFiled: January 21, 1998Date of Patent: August 3, 1999Assignees: Modine Mfg.

Patent number: 4756279Abstract: A control device for the flow of cooling air through an air-liquid radiator of an internal combustion engine comprising a fan frame mounted between the radiator and the fan and being part of a noise damper of the engine. A spring curtain is arranged in the fan frame between the radiator and the fan and isolates the noise damper of the radiator, except when the engine reaches high operating temperatures, which prevents the radiator from absorbing power and the engine from being directly air cooled, thus reducing the prewarming time of the engine.Type: GrantFiled: October 1, 1986Date of Patent: July 12, 1988Assignee: Bayerische Motoren Werke A.G.Inventor: Axel Temmesfeld

Patent number: 4510893Abstract: Cooling circuit for internal combustion engines, with an excess-pressure valve which, when the cooling circuit is under full thermal load, limits the pressure in the feed to a value at which the pressure on the suction side of the coolant pump is always above the boiling pressure of the cooling medium, even at full delivery level of the coolant pump. The efficiency of the cooling function is improved as also the structural expenditure in connection with the cooling circuit is reduced thereby and also by the central arrangement, in the filling stub, respectively, the cap thereof, of additional excess-pressure and vacuum valves, of a throttle for a venting flow, of a level float switch for the filling level indication in the cooling circuit and of a blocking device against the opening of the cap which is under pressure.Type: GrantFiled: July 14, 1983Date of Patent: April 16, 1985Assignee: Bayerische Motoren Werke AGInventors: Erwin Schweiger, Erwin Starmuehler, Axel Temmesfeld
