Problems solved by technology
The structure design of the heat exchange tubes in the existing closed cooling tower is single, and the heat exchange effect is not good. In addition, if the material of the heat exchange tubes is made of carbon steel, copper or aluminum, the abundant air outside the tubes and the water spraying conditions will Accelerate the corrosion of heat exchange tubes and shorten the service life of closed cooling towers
If the heat exchange tube is made of stainless steel or titanium, the price of the closed tower will increase significantly, which is unacceptable to most users

Abstract
The invention discloses a heat exchanger and a closed type cooling tower. The heat exchanger comprises a diverter, a current collector and a plurality of rows of heat exchange tubes arranged in parallel; the diverter and the current collector each comprise a plurality of current diversion branch pipes and a plurality of current collection branch pipes; the heat exchange tubes communicate between the current diversion branch pipes and the current collection branch pipes; the cross sections of the heat exchange tubes are round; the cross sections of the current diversion branch pipes and the current collection branch pipes are oval; the long-axis direction of the ovals is parallel with the axis direction of the heat exchange tubes; and on the projective plane formed by the plane perpendicular to the axes of the current diversion branch pipes and the current collection branch pipes, the adjacent current diversion branch pipes are mutually staggered in the axial direction of the heat exchange tubes, and the adjacent current collection branch pipes are also mutually staggered in the axial direction of the heat exchange tubes. The heat exchanger not only achieves the purpose of enhancingheat transfer, but also reduces the size of a heat exchange tube bundle and the closed type cooling tower.
Description
technical field [0001] The invention relates to cooling equipment for industrial circulating water, in particular to a heat exchanger and a closed cooling tower. Background technique [0002] The cooling or condensation of the process medium in the industrial field generally uses circulating water with a lower temperature. After the circulating water absorbs heat, it needs to evaporate and dissipate heat in the cooling tower to cool down, and then send it to the heat exchanger again to absorb the heat of the process medium. Cooling towers are divided into two types: open type and closed type. In open type cooling towers, the circulating water is in direct contact with the air from the environment for heat transfer, and the water quality is poor; in closed type cooling towers, the circulating water does not contact the ambient air. The water quality is clean. [0003] There is a bunch of heat exchange tubes in the closed cooling tower, the circulating water goes inside the t...
