Warmup acceleration device for internal combustion engine

When the passing of coolant in an internal combustion engine is restricted to accelerate the warm-up of the internal combustion engine and the coolant in this engine is undergoing nucleate boiling, the restriction of the passing of the coolant in the internal engine is maintained. Specifically, the restriction of the passing of the coolant in the internal combustion engine is maintained during nucleate boiling from the beginning of nucleate boiling of the coolant in the internal combustion engine until the maintenance period has elapsed. Thus, the warm-up of the internal combustion engine is effectively accelerated by restricting the passing of the coolant in the engine. Furthermore, the restriction of the passing of the coolant in the internal combustion engine is canceled when the maintenance period has elapsed. Thus, low-temperature coolant flows in the internal combustion engine and the internal combustion engine is cooled by this coolant, so nucleate boiling of the coolant in the engine ...

Apparatus for enhancing the performance of a vehicle air conditioning system

An elongated cylinder is placed towards the front end of a vehicle such as an automobile at a lower level than the air conditioning unit evaporator drain and connected to the evaporator drain by a hose. This cylinder forms a reservoir, spray units are located at the ends or top of the reservoir and, condensate from the air conditioning unit in the reservoir is forced out of the reservoir into the spray units by internally applied air pressure. Outside air created by the vehicle forward movement is captured by one or more flanged pipes and provides the source for the internally applied air pressure. Condensate spray from the cylinder directed by the vehicle radiator fan flows onto the vehicle condenser core so as to assist in removing heat from the circulating freon sending a much cooler freon back into the vehicle.

Le débit passe complètement ou principalement par la dérivation (18) quand le moteur est chaud, mais pas quand il est froid, afin de rendre alors l’évaporateur (23) inactif et de ne pas contrarier une montée en température normale du moteur (13). En plaçant l’évaporateur (23) juste à la sortie du moteur (13), on dispose d’un débit maximal du fluide caloporteur parcourant le circuit de refroidissement (14) et donc d’une récupération plus efficace de la chaleur. Figure pour l’abrégé : F ig. 2 . The evaporator (23) of a heat recovery circuit (24) associated with a cooling circuit (14) of a heat engine (13) is arranged on a bypass (18) of an outlet duct (16) outside the engine, and a valve (17) controls the distribution of the heat transfer flows between the bypass (18) and the parallel portion of the duct (16). The flow passes completely or mainly through the bypass (18) when the engine is hot, but not when it is cold, in order to then make the evaporator (23) inactive and not to interfere with a normal rise in engine temperature (13 ). By placing the evaporator (23) just at the outlet of the engine (13), there is a maximum flow rate of the coolant flowing through the cooling circuit (14) and therefore more efficient heat recovery.

Engine cooling system

The invention concerns an engine cooling system that comprises a cooling circuit (8) and an evaporative cooling arrangement (9). The cooling circuit (8) has a cooling capacity provided by exchanging the heat generated by the engine with ambient air. The evaporative cooling arrangement (9) has a cooling capacity provided by dissipating the heat generated by the engine, by vaporisation of a vaporising coolant in a boiler.

The evaporator (23) of a heat recovery circuit (24) associated with a cooling circuit (14) of a heat engine (13) is arranged on a bypass (18) of an outlet duct (16) outside the engine, and a valve (17) controls the distribution of the heat transfer flows between the bypass (18) and the parallel portion of the duct (16). The flow passes completely or mainly through the bypass (18) when the engine is hot, but not when it is cold, in order to then make the evaporator (23) inactive and not to interfere with a normal rise in engine temperature (13 ). By placing the evaporator (23) just at the outlet of the engine (13), there is a maximum flow rate of the coolant flowing through the cooling circuit (14) and therefore more efficient heat recovery.

Engine cooling system

The invention concerns an engine cooling system that comprises a cooling circuit (8) and an evaporative cooling arrangement (9). The cooling circuit (8) has a cooling capacity provided by exchanging the heat generated by the engine with ambient air. The evaporative cooling arrangement (9) has a cooling capacity provided by dissipating the heat generated by the engine, by vaporisation of a vaporising coolant in a boiler. The cooling capacity of the evaporative cooling arrangement (9) is such that with the cooling capacity of the cooling circuit (8), the global capacity of the cooling system can match, at least peak, cooling demands. As the cooling capacity of the cooling system is divided between the capacity of the cooling circuit and the capacity of the evaporative cooling arrangement, the capacity of the cooling circuit can be reduced in comparison to a conventional cooling circuit which has to match alone peak cooling demands.

The air may be cooled in plural stages (13-16), and sea water may be used for cooling and humidification of the air in the first stage. When the humidity-saturated air is cooled with atomized fresh water in subsequent stages (14-16), the cooler produces a surplus of fresh water.
