1. liquid-cooled coolers, for example, "an industrial water-cooled radiator" provided by CN 217005026U; the invention needs the industrial cooling water pump to perform forced cooling circulation, and exchanges heat with materials and cools;
2. in an air-cooled cooler, for example, in "an air cooler" provided in CN114264169a, forced air cooling is required by using an electric air cooling fan;
3. in the gas-liquid cooler, for example, in "a blockage-preventing wet air cooler" provided in CN216049274U, not only forced gas cooling by an electric air cooling fan but also spray cooling by an additional demineralized water system is required, and periodic water replenishment is required.
