In the industrial field, filters are often provided upstream of critical equipment in order to ensure that the equipment is not damaged or clogged by impurities such as particles carried by the working fluid. For example, in order to improve heat transfer efficiency while reducing drag loss, various new compact heat exchangers are increasingly being introduced, such as printed circuit board heat exchangers. Because the size of the flow channel of the printed circuit board heat exchanger is very small, and the equivalent diameter is only about 2 millimeters, when the heat exchange fluid is not very clean, the flow channel of the heat exchanger can be blocked. In order to prevent the flow passage of the heat exchanger from being blocked, a filter is generally arranged at the fluid inlet end of the printed circuit board heat exchanger, and the impurities such as particles in the working medium and the like are expected to be filtered, so that the micro heat exchange channel of the filter is ensured not to be blocked.
Since the system inevitably generates some impurities in the pipe during installation and the scale and the like on the wall surface of the pipe are peeled off, impurities are present in the pipe at the initial stage of operation, even after long-term operation, and thus the filter needs to be operated reliably for a long time. The filter commonly used at present is generally a filter screen type and is installed on an inlet pipeline of the micro-channel heat exchanger in a flange or welding mode. However, the filter screen of the type can not be cleaned on line, and can only be stopped and replaced if the filter is blocked, so that the effective production time is shortened, and time and labor are wasted; or parallel filters may be provided in the design, but this adds complexity and cost to the system.
