Abstract

The invention discloses a plate-pipe composite heat-exchange-type evaporative condenser. The plate-pipe composite heat-exchange-type evaporative condenser comprises a fan, a water pump, a water distributor, and a water collection pond and further comprises a plate-pipe composite heat exchanger composed of connection among multiple plate-pipe composite heat-exchange sheets, a water inlet header and a water outlet header. The plate-pipe composite heat-exchange sheets comprise heat-transfer plate sheets and coil pipes formed by machining of a heat exchange pipe. Placement grooves are arranged in the heat-transfer plate sheets and matched with the coil pipes in terms of shapes. The coil pipes are arranged in the placement grooves. Heat conduction bonding layers are filled with the gaps between the coil pipes and the placement grooves. Compared with the prior art, the plate-pipe composite heat-exchange-type evaporative condenser has following beneficial effects: the heat conduction bonding layer enables the heat transfer plate sheets to be in full contact with the coil pipes such that the coil pipes have the finned effect through the heat transfer plate sheets and the effective heat exchange area can be effectively increased; the heat transfer plate sheets can introduce cooling water to form a continuous waterflow surface and increases the evaporation area of cooling water; and with an increased effective heat exchange area and an evaporation area of cooling water, heat exchange efficiency is raised and size of a condenser can be reduced.

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...
