Integrating multi-functional lightweight thermostat housing and using method thereof

Abstract

The invention discloses a low-weight thermolator shell with multiple functions integrated. The low-weight thermolator shell comprises a thermolator chamber and a thermolator chamber cover which communicate with each other to form an integrated structure. The thermolator chamber is provided with a small circulating connector and a water inlet. The thermolator chamber cover is provided with a large circulating connector. A thermolator is arranged at the position, close to the thermolator chamber, of an inner cover cavity of the thermolator chamber cover. The thermolator chamber is internally provided with a water inlet cavity and an internally-arranged small circulating channel, and the shell is provided with a degassing connector, a water return opening, a water collecting opening and a temperature sensor connector. Cooling liquid sequentially flows through an engine cylinder head, the water inlet, the water inlet cavity, the thermolator, a cover cavity, the internally-arranged small circulating channel, the small circulating connector and a water pump in the small circulating process. The cooling liquid sequentially flows through the engine cylinder head, the water inlet, the water inlet cavity, the thermolator, the cover cavity, the large circulating connector, a radiator and the water pump in the large circulating process. By the adoption of the design, the small circulating channel is internally arranged, and the structure is compact; and moreover, the integration level of the functions is high, and the low-weight purpose can be achieved.

Description

technical field [0001] The invention relates to a thermostat for a vehicle, in particular to an integrated multifunctional lightweight thermostat housing and a method for using the same, which is particularly suitable for compact structure and light weight through the design of a built-in small circulation passage. Background technique [0002] At present, the relevant components of the engine cooling system are mostly arranged independently of each other, and then connected by pipes. This traditional arrangement and design will cause the engine to be too large, or it cannot be realized in a compact engine layout. After all , The current design trend of the engine is to develop towards a more integrated and lightweight direction, requiring as few parts as possible and a compact structure. [0003] The application publication number is CN102877926A, and the application publication date is January 16, 2013. The invention patent application discloses an automobile engine thermo...

Problems solved by technology

[0004] First of all, the design uses the motor to drive the piston valve to select the small cycle or the large cycle, instead of being automatically selected by the temperature sensor according to the temperature of the coolant, the timeliness of the control is poor, and it is easy to lag. The setting not only increases the cost, but also increases the overall space of the thermostat;

[0005] Secondly, this design can only adjust the flow and flow direction of the coolant in the thermostat through the operation of the piston valve. Once it flows out of the thermostat, it still needs to be connected with a large number of external junction pipes, which takes up more space. huge
