Embodiment Construction

[0017] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] A condensing expansion tank such as figure 1 , 2 As shown, it includes a primary expansion tank 1 and a secondary expansion tank 2 arranged left and right,

[0020] The inside of the first-stage expansion tank 1 is provided with a partition 3, and the partition 3 includes a vertical partition and a horizontal partition arranged vertically in the first-stage expansion tank 1, and the horizontal partition is located at the top of the first-stage expansion tank 1. At the highest water level, the two vertical partitions are respectively arranged on the upper and lower sides of the horizontal partition; a liquid flow channel 4 is arranged between the vertical partition and the horizo...

Abstract

The invention provides a condensing-type expanding water tank comprising a primary expanding water tank and a secondary expanding water tank which are in left-right arrangement. A partition and a liquid passageway are arranged inside the primary expanding water tank, an air incoming pipe and a high-pressure air release valve are arranged on the primary expanding water tank, and a water replenishing pipe is arranged below the primary expanding water tank; an upper water collection chamber is arranged on the upper portion of the secondary expanding water tank, a lower water collection chamber isarranged at the bottom of the secondary expanding water tank, multiple broken-line-shaped water pipes communicating the upper water collection chamber with the lower water collection chamber are arranged in the middle of the secondary expanding water tank, and fins are arranged around each water pipe; an exhaust pipe is arranged on the side face of the primary expanding water tank and positionedin the upper water collection chamber, and a water outgoing pipe communicated with the water replenishing pipe is arranged at the bottom of the lower water collection chamber. The condensing-type expanding water tank has the advantages that the expanding water tank can quickly condense water vapor discharged by an engine cooler into liquid water to flow back into the water tank through circulation; frequency of opening a water tank air release valve in a conventional cooling water tank is lowered, and loss of cooling liquid in a cooling system is reduced.

Description

technical field [0001] The invention belongs to the technical field of vehicle cooling water tank design, and in particular relates to a condensing expansion water tank. Background technique [0002] With the continuous strengthening of the engine, the requirements for the cooling system are becoming more and more stringent. The cooling water tank turns the cooling system into a permanent closed system, avoids the continuous entry of air, reduces the oxidation and corrosion of the inside of the cooling system, separates the water vapor in the cooling system, and keeps the pressure in a stable state. [0003] However, in the existing cooling water tank, when the pressure of the water tank reaches a certain value, the valve needs to be opened to deflate, which causes the engine water tank to be regularly replenished with water. Contents of the invention [0004] In view of this, the present invention aims to propose a condensing expansion water tank to reduce the frequency ...
