Description

Technical Field

[0001] The utility model relates to the technical field of liquid cooling, in particular to a multi-stage heat recovery condensation cooling tower. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. A cooling tower uses water and air flow to exchange heat and generate steam. The steam evaporates and takes away the heat to achieve the principles of evaporative heat dissipation, convection heat transfer and radiation heat transfer to dissipate the waste heat generated in the industry to lower the gas temperature. This is an evaporative heat dissipation device to ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.

[0003] The existing condensing cooling tower cools the hot air and the water temperature rises. Usually, the cooling water is allowed to cool naturally in the water reservoir and then cools the hot air again. The heat absorbed by the cooling water cannot be well utilized, resulting in a waste of resources. Utility Model Content

[0011] Preferably, a water pipe is provided on the top of the water pump, the water pipe runs through the bottom of the condensation tower shell, and eight groups of water spray pipes are provided on the side of the top of the water pipe.

[0012] Beneficial Effects

[0013] In the utility model, thermal insulation foam, a water outlet pipe, a water collecting pan and a water outlet are adopted. After the cooling water absorbs the heat in the hot air inside the cooling tower, it is gathered inside the water collecting pan. Since the hot air moves from the bottom to the top of the cooling tower, the cooling water on the surface of the bottom water collecting pan contacts with the hot air with the highest temperature, so that the water temperature on the surface of the bottom water collecting pan is higher, and the water temperature on the surface of the top water collecting pan decreases successively. Cooling water with different temperature gradients enters the inside of the water outlet pipe through the water outlet. The water outlet pipe transports the warm water to the place where heating is needed to release the heat, recycles the heat, saves energy, and the thermal insulation foam insulates the water outlet pipe to reduce heat loss.
