Abstract
The utility model relates to a thermostat housing assembly, which comprises a thermostat housing and an expansion kettle. The thermostat housing is arranged at a water outlet of an engine, the expansion kettle is arranged on the upper portion of the thermostat housing, and an internal cavity of the expansion kettle is communicated with the inside of the thermostat housing. The height of the expansion kettle can be effectively decreased on the premise of achieving gas exhausting and water supplementing functions of the engine, so that arrangement of a front cabin of a finished vehicle is benefited.
Description
[technical field]
The utility model relates to a kind of housing assembly, and in particular, the utility model relates to a kind of thermostat housing assembly that is arranged in the motor water outlet.
[background technique]
Car engine cooling system is mainly used in cooling action in running order vehicle motor, air-conditioning system etc. is provided.Engine-cooling system has generally included cooling jacket, cooling line, radiator, expansion kettle etc.The expansion kettle is usually placed in the motor front deck of vehicle, and it is mainly used in and stores the too much cooling liquid that produces owing to thermal expansion, and keeps the pressure in the cooling system is remained between the highest setting value and the minimum setting value.The expansion kettle is usually placed in the highest point of the whole cooling system of motor, makes the gas that produces in the engine-cooling system to be drained in the expansion kettle by a pipeline that makes progress like this, thereby makes gas separate with cooling liquid.In addition, the expansion kettle also has the function of carrying out moisturizing to engine water pump, to reduce the risk of cavitation of pump.
The expansion kettle all is to be arranged in the front deck as individual part usually, and its cooling system with two flexible pipes and motor links to each other.Usually have gas-liquid two-phase in the expansion kettle when the vehicle motor proper functioning, wherein Ye Tai cooling liquid is in the below, is air above.
Chinese patent application CN200910266686.8 discloses a kind of electric control cooling system of engine, comprise the electric water pump of connecting between motor and the radiator that has radiator fan, the expansion kettle is connected with the top of radiator by pipeline one end, and the other end is connected with the bottom of radiator.
In order to guarantee engine-cooling system proper functioning and satisfy engine exhaust and moisturizing requirement, the minimum liquid level in the kettle that need guarantee in the time of the expansion kettle design to expand will be higher than the peak of engine-cooling system.This has just required the height of expansion kettle setting to improve as much as possible.Yet the front deck for some compact type dolly arranges that because the height of hood is very low, the height of expansion kettle also must correspondingly reduce, and this has produced the layout difficulty of expansion kettle in the motor front deck.
[model utility content]
A purpose of the present utility model is, provide a kind of thermostat housing assembly that can overcome aforementioned disadvantages, and described thermostat housing assembly is simple in structure, rationally distributed.
Above-mentioned purpose of the present utility model and other purposes solve by following technical solution:
The utility model provides a kind of thermostat housing assembly, wherein said thermostat housing assembly comprises thermostat housing that is arranged in the motor water outlet and the expansion kettle that is arranged on described thermostat housing top, and the internal chamber of described expansion kettle is communicated to the inside of described thermostat housing.
