Description

Intercooler with fractal flow passage structure Technical Field The utility model relates to the technical field of machine tool machining, in particular to an intercooler with a fractal flow passage structure. Background In the field of modern industry, an intercooler is used as a key heat dissipation component of equipment such as an engine, an air compressor and the like, and the performance of the intercooler directly influences the operation efficiency and the service life of the equipment. The traditional intercooler adopts a single channel or simple multichannel structure, so that a plurality of limitations are exposed in practical application, the air flow distribution is uneven due to the single channel design, when the air flows in the intercooler, the local flow velocity is too high or too low due to the difference of flow channel resistance, so that the high-temperature air cannot be uniformly cooled, further, local hot spots are formed, the overall heat dissipation efficiency is reduced, and the shunting effect can be improved to a certain extent due to the simple multichannel structure, but the high-efficiency uniform distribution of the air flow is still difficult to realize due to the lack of scientific flow channel layout.
