Description

Technical Field

[0001] This utility model relates to the field of fuel water cooling agent technology, and more specifically, to a fuel water cooling agent assembly. Background Technology

[0002] The currently used fuel water cooling system consists of an electric pump assembly and a fuel filter assembly. The electric pump assembly and the fuel filter assembly are connected by threads, and the connection structure is complex. Using only a single sealing ring will reduce the sealing performance of the connection. In addition, the fuel filter assembly connected to the electric pump assembly has a fixed size, making it difficult to control and reduce the production cost of the fuel water cooling system assembly.

[0003] For example, the fuel filter sealing structure and fuel water cooler disclosed in announcement number CN212985424U, the fuel filter sealing structure of this utility model includes: a filter housing and a sealing element, the filter housing is provided with a filter connector that is detachably connected to the electric pump assembly; the electric pump assembly includes an electric pump, the bottom of the electric pump is provided with an electric pump connector that is detachably connected to the filter connector; the sealing element is provided between the filter connector and the electric pump connector.

[0004] As can be seen from the above-disclosed scheme, the filter housing is connected to the electric pump assembly connector via threads and sealed by a single sealing element. Due to the complex structure at the interface between the electric pump assembly connector and the filter housing, the sealing effect is greatly reduced, which in turn reduces the assembly safety of the fuel-water cooling system assembly. Furthermore, the filter housing connected to the electric pump assembly connector has a fixed size, making it impossible to purchase suitable, low-cost fuel filters on the market. This makes it difficult to reduce the production cost of the fuel-water cooling system assembly, thereby reducing its market competitiveness. Utility Model Content
