As shown in fig. 1 to 3, the outer sidewall of the thermostat assembly 200 is provided with a first positioning portion 220, and one end (e.g., the left end) of the thermostat assembly 200 is installed in the water outlet 110.
As shown in fig. 1-3, wherein a closure cap 300 is coupled to the cylinder head 100 to enable packaging of the thermostat assembly 200 at the water outlet 110. Specifically, the cover 300 is provided with a mounting cavity 310 for mounting the other end (e.g., the right end) of the thermostat assembly 200. The inner side wall of the mounting cavity 310 is provided with a second positioning portion 320 for positioning and matching with the first positioning portion 220. Thus, when the thermostat assembly 200 needs to be packaged, the other end of the thermostat assembly 200 is inserted into the mounting cavity 310, and the thermostat assembly 200 and the cover 300 are accurately preassembled by using the positioning fit between the first positioning portion 220 on the outer side wall of the thermostat assembly 200 and the second positioning portion 320 on the inner side wall of the mounting cavity 310. The thermostat assembly 200 is then packaged by inserting one end of the thermostat assembly 200 into the water outlet 110 and connecting the cap 300 to the cylinder head 100.
The traditional location structure of processing out on the inside wall of delivery port 110 has not only increased the flow resistance of delivery port 110 department coolant liquid, processes out location structure moreover on the inside wall of delivery port 110, need carry out the special-shaped processing, and the processing degree of difficulty is high, and the processing cost is high. The thermostat packaging structure of the embodiment of the application only needs to process the second positioning portion 320 on the inner side wall of the mounting cavity 310 of the cover 300 and set the first positioning portion 220 on the outer side wall of the thermostat assembly 200, so that the flow of the coolant at the water outlet 110 is not affected or interfered, the pumping power of the pump body is not increased, and the energy consumption is reduced. Meanwhile, the second positioning portion 320 is processed on the inner side wall of the mounting cavity 310, and the first positioning portion 220 is arranged on the outer side wall of the thermostat assembly 200, so that the process can be completed only in a casting stage, and the process is simple, convenient, low in processing difficulty and low in processing cost.
The connection between the cylinder head 100 and the cover 300 can be realized by means of screw connection, clamping connection and the like, and the thermostat assembly 200 can be packaged in a space formed by the water outlet 110 and the mounting cavity 310. The positioning fit between the first positioning portion 220 and the second positioning portion 320 can be realized by means of insertion (insertion fit between the protrusion and the groove) or by means of clamping (clamping fit between the hook and the clamping groove), and it is only necessary to satisfy the requirement for the thermostat assembly 200 and the sealing cover 300 to realize accurate and reliable assembly connection, and the exhaust hole 210, the first positioning portion 220 and the second positioning portion 320 are correspondingly arranged.
