As shown in fig. 4, the filter device a is integrally disposed on the periphery of the water pump and is communicated with the water pump through the input interface 20, water in the water pump is introduced into the filter device a, and filtered and stabilized under the action of the filter screen 40 in the main chamber 11 of the filter device a, and then is output to the heat dissipation pipeline of the frequency converter B through the branch chamber 12, so as to provide sustainable circulating cooling water for the frequency converter B, but based on the circular outer body of the pump body C of the water pump and the position set by the frequency converter B, the installation of the filter device a is very difficult, meanwhile, the water input in the pump body C has a certain pressurizing force, the unstable and intermittent water pressure is easy to occur, the heat dissipation effect of the frequency converter B is affected, and the filter device a is limited in the installation position and the volume of the filter device a is not easy to control.
Accordingly, the present disclosure constructs the chamber of the housing 10 as a constituent structure of the main chamber 11 and the lateral branch chamber 12 while the main chamber 11 and the branch chamber 12 are communicated through the through-hole, as shown in fig. 2. The main chamber 11 and the branch chamber 12 form an acute angle in the installation direction towards the pump body C of the water pump, so that water with a certain pressure input by the water pump is subjected to backflow and pressure stabilization under the buffer action of the closed structure of the main chamber 11, and then is input into the branch chamber 12, so that the water pressure of the water output by the branch chamber 12 is stable and continuous. Secondly, the backflow pressure stabilization of the main chamber 11 can also ensure that the water pressure is stabilized at about 0.5Mpa, so that the problems of deformation, water leakage and the like of the heat dissipation pipeline caused by impact on the heat dissipation pipeline are avoided.
In fact, as shown in fig. 2, the main chamber 11 is configured in a cylindrical shape, one end of which is configured as an open end for connection with the input interface 20; the other end is constructed as a closed structure for pressure stabilizing and backflow of water entering the main chamber 11 through the input interface 20.

Firstly, the input interface 20 is embedded into the mounting interface of the pump body C of the water inlet pump through the action of the positioning strip 21, and is fixedly connected through a welding mode, then the shell 10 is fixedly connected to the output interface of the frequency converter B through the threaded connection of the outer surface of the branch cavity, and then under the action of the positioning groove of the main cavity 11, the butt joint positioning with the input interface 20 is realized, after the butt joint positioning is finished, the position of the main cavity 11 is fixedly connected through the connecting piece 30, finally the filter screen 40 is installed, the main cavity 11 is closed through the detachable plug 14, and thus the integral mounting and fixing of the whole filtering device a are completed.
The foregoing has outlined rather broadly the more detailed description of the present disclosure in order that the detailed description of the principles and embodiments of the disclosure may be implemented in order that the detailed description may be better understood, or in order that the present disclosure may be better understood. It should be noted that it would be apparent to those skilled in the art that various improvements and modifications could be made to the present disclosure without departing from the principles of the present disclosure, and such improvements and modifications would be within the scope of the claims of the present disclosure.
