Embodiment Construction

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

[0031] Such as image 3 As shown, the expansion kettle assembly 1 includes an expansion kettle 11, an expansion cavity 14, and a pressure cover 12. The expansion kettle 11 has an outlet 111 communicating with the atmosphere, the expansion kettle 11 is connected to the expansion cavity 14, and the expansion cavity 14 has a filling port 13 The pressure cap 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, and the pressure cap 12 is a two-way pressure valve, which is controlled by the pressure cap 12 The expansion cavity 14 is connected and isolated from the expansion kettle 11.

[0032] In the normal state, the pressure cover 12 is closed and is not connected to the expansion kettle 11....

Abstract

The present invention provides an expansion kettle assembly, the expansion kettle assembly includes an expansion kettle, an expansion chamber, and a pressure cover, the expansion kettle has an outlet communicating with the atmosphere, the expansion kettle is connected to the expansion chamber, and There is a filling port on the expansion chamber, the pressure cover is connected to the filling port, the expansion chamber has a circulating liquid inlet and a circulating liquid outlet, the expansion chamber is higher than the liquid level of the radiator, and the pressure The cover is a two-way pressure valve, and the pressure cover controls the communication and isolation between the expansion chamber and the expansion kettle. The present invention adds a very small expansion cavity connected in series with the expansion kettle, and there is no restriction on the arrangement of the expansion kettle, which greatly facilitates the arrangement of the cooling system and the engine compartment, and the expansion cavity participates in the cooling cycle, which has better heat dissipation performance .

Description

Technical field [0001] The invention relates to a cooling circulation system, in particular to an expansion kettle assembly. Background technique [0002] The automobile cooling system keeps the engine in a proper temperature range under all working conditions. The cooling system is an important part of the vehicle. The main component of the heat exchange of the cooling system is the radiator assembly. The high-temperature coolant in the engine enters the radiator assembly, and then the radiator is cooled by natural wind and a cooling fan, and the cooled liquid enters the engine for circulating cooling. Most of the cooling circulation system is equipped with an expansion kettle, which has the function of storing coolant, replenishing water in time, and exhausting gas in time. The existing cooling circulation system mostly adopts two kinds of open cooling circulation system and closed cooling circulation system. [0003] Such as figure 1 As shown, in the open cooling cycle system,...
