Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration, in particular to a three-way valve water channel system for a cold air machine. Background Art

[0002] Chinese Patent No. ZL202121237297.5 discloses an air cooler, including a lower water tank, a water receiving pan, a condenser and a wet curtain assembly; the water receiving pan is arranged above the lower water tank and forms a water flow channel, the water flow channel has a water outlet, and the water outlet is connected to the lower water tank; the condenser is arranged in the water flow channel; the wet curtain assembly is located above the water flow channel. The technical solution of the utility model is provided with a water receiving pan above the lower water tank, a condenser is arranged in the water flow channel of the water receiving pan, and the wet curtain assembly is arranged above the water flow channel. The cold water that falls after the wet curtain evaporates and dissipates heat falls into the water flow channel and exchanges heat with the condenser in time. In addition, the volume of the water flow channel is small, which ensures that the flow rate of water in the water flow channel is fast, and the water falling into the water flow channel and the condenser have better heat exchange efficiency and heat exchange effect. The water flow channel can be replenished with the newly fallen cold water on the wet curtain assembly in time to form a circulation, thereby increasing the temperature difference between the condenser and the water flow in the water flow channel, and improving the heat exchange efficiency and heat exchange effect of the condenser.

[0003] The falling water of the wet curtain assembly of the air cooler exchanges heat with the condenser for cooling and returns to the lower water tank. However, when the temperature of the liquid in the lower water tank is low, it cannot enter the condenser to dissipate heat to the condenser. The liquid in the water tank can only be used to supplement the wet curtain assembly. Its utilization rate is not high, and therefore needs further improvement. Utility Model Content

[0004] The utility model aims to provide a three-way valve water circuit system for an air cooler, wherein a second water circuit is provided between a heat exchanger assembly and a casing, and a three-way reversing valve for opening and closing the first water circuit and the second water circuit is provided between the first water circuit and the second water circuit.

When the water temperature of the casing is relatively high, the water of the casing is pumped onto a water curtain assembly, and after the heat is dissipated by the water curtain assembly, the water falls into the heat exchanger assembly for heat exchange, which can improve the service life of the water curtain assembly to a certain extent and effectively utilize the water of the casing. When the water temperature of the casing is relatively low, the water entering the heat exchanger assembly is mixed with the water falling from the water curtain assembly into the heat exchanger assembly, and the mixed liquid exchanges heat with the heat exchanger assembly together, and absorbs the heat of the heat exchanger assembly together, thereby accelerating the heat exchange efficiency and the heat exchange effect.
