Test system of multifunctional heat exchanger

The utility model relates to a test system of a WLSZ multifunctional heat exchanger, which comprises a tested heat exchanger, a cooler, a heater, a cooling tower, a temperature reducing device, a supercooler, a plurality of sets of flow rate testing pipeline parallel devices and a cross direction changing pipeline device, wherein the heater, the temperature reducing device and the supercooler areconnected with each other to form a heat source loop, the heater is connected with the tested heat exchanger to form a thermal cycle loop, the tested heat exchanger is connected with the cooler to form a cold cycle loop, and the cooler is connected with the cooling tower to form a cold source loop; the plurality of sets of flow rate testing pipeline parallel devices are arranged on the thermal cycle loop and the cold cycle loop, and the cross direction changing pipeline device is arranged at the position close to the interface end of the tested heat exchanger and between the thermal cycle loopand the cold cycle loop. The test system can be used for testing the thermal engineering property and the fluid resistance characteristic of heat exchanger products with multiple specifications and types such as plate type, tube type, spiral plate type and the like.
