Description

[Technical field]

[0001] The utility model relates to the technical field of coolers, in particular to an evaporative cooler. [Background technology]

[0002] The evaporative cooler can be regarded as a combined heat exchanger of a cooler and a cooling tower using water as the cooling medium. Usually, in order to save water for water-cooled coolers in industry, water is cooled in a cooling tower and recycled. The evaporative cooler combines the cooler and the cooling tower into one. The cooled process fluid flows in the tube, and the water and air flow outside the tube at the same time. The heat of the fluid in the tube is transferred to the air through the water outside the tube to achieve the purpose of cooling. The existing condenser is as follows:

[0003] For example, patent publication number CN02255480.7 discloses an evaporative cooler, including a water tank, an air inlet, a heat exchange tube bundle, a spray device, a water collector, a cooling fan and a water treatment device. The utility model reasonably arranges the above components according to the heat transfer principle, and strengthens the heat transfer through the evaporation of the water film on the surface of the heat exchange tube bundle shell. Compared with the prior art, it has the advantages of small footprint, high heat transfer efficiency, low investment, low circulating cooling water consumption, and easy installation.

[0004] In actual operation, the utility model mainly utilizes the heat transfer principle and the evaporation of the water film on the surface of the heat transfer tube bundle to enhance the heat transfer effect and further improve the efficiency of heat transfer. Although the above scheme can improve the efficiency of heat transfer, the following problems still exist: the cooler is mainly connected to the spray branch pipe through a water pipe, but the cooling water will increase or decrease with the change of seasons during use. For example, in summer, the cooling water consumption will increase, and in winter it will decrease. If it is in summer, when the water output increases, it is difficult to meet the water output demand, which can easily cause the water output efficiency to decrease. In winter, since the water output of the water pipe is fixed, it is difficult to control the water output during the water output process, which causes water waste. [Utility Model Content]
