Automobile cooling liquid expansion box with excellent heat insulation effect

Abstract

The invention discloses an automobile cooling liquid expansion box with excellent heat insulation effect. The automobile cooling liquid expansion box comprises an upper shell body, the lower end of the upper shell is connected with a lower shell, the middle of the upper end surface of the upper shell is in threaded connection with a sealing cover, an air outlet is formed in the position, close tothe upper edge, of one side of the upper shell, the upper end surface of the upper shell is fixedly provided with a threaded connection seat in the sealing cover, a liquid inlet is formed in the threaded connecting seat, a connecting cap is arranged on the lower end surface of the threaded connecting seat in the upper shell, the lower end of the connecting cap is connected with a flow guide box, the upper end face of the flow guide box is provided with a splash-proof cover, and a connecting port is fixedly installed in the middle of the upper end surface of the splash-proof cover. The automobile cooling liquid expansion tank with the excellent heat insulation effect can provide long-term comprehensive protection for the tank body, the flow guide box can effectively control the flowing direction of the cooling liquid, the design of the scale bars bring convenience to use and better prospect for use.

Description

technical field [0001] The invention relates to the field of coolant expansion tanks, in particular to an automobile coolant expansion tank with excellent heat insulation effect. Background technique [0002] The car expansion tank is a coolant storage tank that ensures that the radiator is filled with coolant, so that the coolant in the radiator has room to release when it is heated and expands, and it has compensation capacity when it shrinks when cooled, and there is a certain amount of surplus water to avoid consumption A device that lacks water; the existing automobile expansion tank has certain disadvantages in use, such as a single structure, which cannot provide long-term comprehensive protection for the tank, and there is no diversion box design inside, so it is difficult to effectively control the flow direction of the coolant , the design without scale bars makes it impossible to visually check the use of the coolant inside the box, which brings inconvenience to t...
