Plate and tube composite heat exchange evaporative condenser

Abstract

The invention discloses a plate-tube composite heat exchange type evaporative condenser, which includes a fan, a water pump, a water distributor, and a sump; and a plate-tube composite heat exchanger; The tube composite heat exchange fins are connected by inlet headers and outlet headers; the plate tube composite heat transfer fins include heat transfer plates and coils processed from heat exchange tubes; the heat transfer plates are equipped with A groove, the shape of the placement groove matches the shape of the coil; the coil is placed in the placement groove, and the gap between the coil pipe and the placement groove is filled with a thermally conductive adhesive layer. Compared with the prior art, the heat-conducting adhesive layer of the present invention makes the heat transfer plate fully contact with the coil, and the coil can produce a rib effect through the heat exchange plate, increasing the effective heat exchange area; the heat exchange plate can drain water The cooling water forms a continuous water flow surface, increasing the cooling water evaporation surface area; increasing the effective heat exchange area and cooling water evaporation area, which not only improves the heat exchange efficiency, but also helps reduce the volume of the condenser.

Description

technical field [0001] The invention relates to the field of heat exchange equipment, in particular to an evaporative condenser of plate type and coil type composite heat exchange type. Background technique [0002] At this stage, evaporative condensers on the market usually use curved coils to form a heat exchanger. The outer surface of the heat exchanger is cooled by spray water, and the circulating spray water is used to evaporate and take away heat. However, the outer surface of the heat exchange tubes of this type of coil heat exchanger is generally smooth, and the heat exchange efficiency is low. At the same time, the heat exchange surface area of ​​cooling water evaporation is small, and the distance between the coils needs to be enlarged to increase the heat exchange time between cooling water and air, resulting in a bulky heat exchanger. On the other hand, since there is no medium between the upper and lower tubes of the coil to guide the flow of cooling water, whe...

Problems solved by technology

Although the invention patent has improved the heat exchange efficiency to a certain extent, the heat exchange efficiency has not been greatly improved because the heat exchange efficiency is only improved by increasing the utilization rate of cooling water.
