Auxiliary water tank device and engine cooling system

Abstract

The invention provides an auxiliary water tank device and an engine cooling system. The auxiliary water tank device comprises a water tank and an upper cover for covering a water filling nozzle of the water tank, wherein the water tank is provided with an overflow gate below the water filling nozzle and an air inlet below the overflow gate; the lower end part of the water tank is provided with a water outlet; a cavity of the water tank is internally provided with a degassing cavity; the upper end of the degassing cavity is communicated with the air inlet; an air outlet arranged at the lower end of the degassing cavity is arranged at the lower part of the cavity of the water tank; the air inlet is used for communicating with the air outlet of a main body of the engine cooling system; and the air inlet is arranged above the air outlet of the main body of the engine cooling system. The degassing device is arranged in the water tank so that the auxiliary water tank can be juxtaposed with the cooling system and can be suitable for being installed on lower vehicles with low height for use. Therefore, the auxiliary water tank in the embodiment has wider application range.

Description

technical field [0001] Embodiments of the present invention relate to vehicle equipment, in particular to an auxiliary water tank device and an engine cooling system. Background technique [0002] At present, the cooling system in the car is usually replenished with liquid through the auxiliary water tank, and the gas in the cooling system is removed by the auxiliary water tank, so that the cooling device in the car can normally cool the engine. [0003] like figure 1 As shown, the specific structure of the auxiliary water tank in the prior art includes: a water tank 101, an upper cover 102 for covering the water injection port of the water tank 101, an overflow port 103 connected to the water tank 101 below the water injection port, and an overflow port 103 located below the overflow 103. The air inlet 104 communicated with the inner cavity of the water tank 101 and the water outlet 105 located at the lower end of the water tank 101 communicated with the water tank 101 . ...

AI Technical Summary

Problems solved by technology

[0004] It can be seen from the above that the installation position of the auxiliary water tank in the prior art is relatively high, and the auxiliary water tank cannot be installed side by side with the cooling system, which occupies a relatively high longitudinal space in the vehicle. Therefore, the auxiliary water tank in the prior art is not suitable for installation to a height of used in lower vehicles
