Embodiment Construction

[0030] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] like image 3 As shown, the expansion pot assembly 1 includes an expansion pot 11, an expansion chamber 14, and a pressure cover 12. The expansion pot 11 has an outlet 111 connected to the atmosphere. The expansion pot 11 is connected to the expansion chamber 14, and the expansion chamber 14 has a filling port 13. , the pressure cover 12 is connected to the filling port 13, the expansion chamber 14 has a circulating liquid inlet 141 and a circulating liquid outlet 142, the expansion chamber 14 is higher than the liquid level of the radiator 2, the pressure cover 12 is a two-way pressure valve, and the pressure cover 12 controls The communication and isolation between the expansion chamber 14 and the expansion kettle 11 .

[0032] During the normal state, the pressure cover 12 is closed and does not communicate with the expansion kettle...

Abstract

The invention provides an expansion tank assembly comprising an expansion tank, an expansion chamber and a pressure cap. The expansion tank connected with the expansion chamber is provided with an outlet communicated with the atmosphere, the expansion chamber is provided with a filling port, the pressure cap is connected with the filling port, the expansion chamber higher than a liquid level of a cooler is provided with a circulating liquid inlet port and a circulating liquid outflow port, and the pressure cap is a two-way pressure valve and controls communication and isolation of the expansion chamber and the expansion kettle. The small expansion chamber in series connection with the expansion tank is added, so that any restrictions on arrangement of the expansion tank are avoided, and great convenience is brought to arrangement of a cooling system and an engine compartment; besides, the expansion chamber participates in cooling circulation, so that the expansion tank assembly has good cooling performance.

Description

technical field [0001] The invention relates to a cooling circulation system, in particular to an expansion kettle assembly. Background technique [0002] The car cooling system keeps the engine in an appropriate temperature range under all working conditions, and the cooling system is an important part of the whole car. The main component of heat exchange in the cooling system is the radiator assembly. The high-temperature coolant in the engine enters the radiator assembly, and then cools the radiator through natural wind and cooling fans. The cooled liquid then enters the engine for circulating cooling. Most cooling circulation systems are equipped with expansion kettles, which have the functions of storing cooling liquid, timely replenishing water, and timely exhausting. The existing cooling circulation system mostly adopts two kinds of open cooling circulation system and closed cooling circulation system. [0003] like figure 1 As shown, in the open cooling cycle syst...
