The invention provides a water pump used for an engine which can increase the flow area of cooling liquid before pumping is simple in structure. A first connector and a second connector are arranged on a water pump shell body, the first connector is used for connecting with a branch pipe connector of the large circulation, and the second connector is used for connecting with a branch pipe connector of the small circulation; water way connectors of the large circulation and the small circulation are arranged separately, during the large circulation, the cooling liquid enters the water pump only through the first connector and then enter the engine, and during the small circulation, the cooling liquid enters the water pump only through the second connector and then enter the engine; during transition period that the small circulation is switched into the large circulation, the second connector only allows flowing of the cooling liquid which passes through warm wind, the cooling liquid which passes a radiator can only enter the water pump from the first connector and then enter the engine, so that the flow area of the cooling liquid before pumping is increased, occurrence of cavitation due to low pressure before pumping is prevented, meanwhile layout difficulty of cooling system pipelines is reduced.

Water pump used for engine

The utility model discloses an engine thermoregulator module, the thermoregulator module is based on the thermoregulator seat of installation thermoregulator, and the engine outlet?port that has integrateed on it, retarber advance water return interface and adjust the temperature big tiny loop interface, the retarber advances the corresponding UNICOM of water return interface retarber and enters the return water chamber, the intake antrum looks UNICOM of retarber return water chamber and thermoregulator, engine outlet?port and the retarber interface inner cavity unicom of intaking. The utility model relates to an engine thermoregulator module's use has been simplified cooling system and has been arranged, need not to change engine body structure. Furthest's reduction cooling system arrange the degree of difficulty, the cooling system that basically can not change former car arranges, has reduced system development time and development cost.

The invention belongs to the technical field of automobile cooling systems, and relates to a fan shock absorber device. The fan shock absorber device comprises a fan mounting flange, a rubber dampingsleeve assembly, an intermediate flange, an anti-falling casing pipe, a dual tooth surface wedge-shaped locking washer A and a connecting bolt B; the rubber damping sleeve assembly is installed between the fan mounting flange and the intermediate flange; the connecting bolt B penetrates through the dual tooth surface wedge-shaped locking washer A, the fan mounting flange, the rubber damping sleeveassembly and the intermediate flange in sequence, and the fan mounting flange is fixed to the intermediate flange; and the anti-falling casing pipe is arranged on the intermediate flange through theconnecting bolt B in a press fitting mode. The fan shock absorber device has the advantages of elimination of a traditional silicone oil fan clutch, the simple structure, convenient installation and removal, firm connection and light weight, and the cost is reduced greatly; the fan shock absorber device is of an assembly type, and internal components can be replaced during maintenance separately;the maintenance economy is good; the speed ratio of a fan to a crankshaft pulley is 1, with no slip, and the working efficiency of the fan is improved.

Fan shock absorber device

The invention discloses a cooling module used for automobiles, and belongs to the technical field of the automobiles The cooling module used for the automobiles comprises a radiator assembly, an intercooler assembly and a wind shield; one of the two opposite sides of the intercooler assembly in a first direction is provided with fixing structures in an outward extending manner, and the other sideis provided with supporting structures, used for supporting the radiator assembly, in an outward extending manner; the radiator assembly is detachably connected with the fixing structures and the supporting structures; and the wind shield is detachably connected with the radiator assembly According to the cooling module used for the automobiles, by installing the fixing structures and the supporting structures on the intercooler assembly, the radiator assembly can be installed and fixed, and stable assembling of the cooling module is realized; compared with the prior art, the cooling modulecancels an installing framework for the radiator assembly, and thereby, the weight of the cooling module can be reduced, and reduction of energy consumption is facilitated; and in addition, the radiator assembly and the intercooler assembly are detachably connected as well as the radiator assembly and the wind shield, so that later maintenance is facilitated

Cooling module used for vehicles

The invention relates to the technical field of engines, and particularly discloses a commercial vehicle parking heating system. The commercial vehicle parking heating system comprises a water heatingtype heater, a warm air radiator, a storage battery, a urea system, an engine and a main fuel tank; the water heating type heater comprises a heating device and a water pump, the water pump is used for driving cooling liquid to flow through the heating device, the heating device is used for heating the cooling liquid which flows through the heating device; the water heating type heater and the warm air radiator are connected in series to form a first circulating waterway, the warm air radiator is used for providing heat for a cab air-conditioning system; the water heating type heater and thestorage battery are connected in series to form a second circulating waterway; the water heating type heater and the urea system are connected in series to form a third circulating waterway; and the water heating type heater is sequentially connected with the main fuel tank, the engine and the warm air radiator in series to form a fourth circulating waterway. According to the commercial vehicle parking heating system, the water heating type heater can perform heat supplying to the warm air radiator, the storage battery, the urea system, the engine and the main fuel tank, and the functions arediversified.
