Problems solved by technology
If a single-piece coil is used to connect the header with thread, because the size of the nut and the working position of the wrench must be considered, the distance between the tubes is relatively large. A certain heat dissipation area needs to increase the tube path, which eventually leads to excessive resistance in the tube

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0018] as attached figure 1 As shown, a coil unit for a counter-flow closed-type cooling tower, the unit consists of two "3h-shaped" conversion heads 8, 3 with one turning four up and down to form four straight pipe sections 4 in staggered arrangement, and consists of The positioning piece 5 fixes the distance between the tubes, and then the "U-shaped" tube row 7 forms a left and right four-way parallel coil tube on the vertical plane. The upper and lower interface ends 10, 1 of the coil unit are in the form of bell mouth pipe ends commonly used in refrigeration pipelines with nuts, and can be connected with the upper horizontal header 11 and the lower horizontal header 12 of the counterflow closed cooling tower respectively. This structure adopts the threaded connection between the coil unit and the upper horizontal header 11 and the lower horizontal ...

The invention claims a combining method of pipe coil unit for back-flowing closed cooling tower. The combining process is: at first, an interface end of the pipe coil unit is a tunnel pipe end added with a nut to connect with a level header pipe of the closed cooling tower. A wave cutting pipe is respectively adjacent to an interface end to adjust position of the interface end; then two wave cutting pipe are welded respectively by two inlet ends of an upper and a lower four-way direct pipe section by an one-to-four ''3h'' exchanging header; then fixing the four-way direct pipe section by a positioning piece and maintaining a distance between the four-way direct pipes; finally, connecting adjacent four-way direct pipes on a vertical surface by an U-shaped pipe makes each four-way direct pipe form a four-way parallel connected pipe coil with equal stroke and resistance from left to right and back and forth. The invention makes the pipe coil easy to mount and exchange, which is beneficial to release air and discharge water. A water pouring filler can be placed between two monitors, which improve radiating effect of unit area.
Description
technical field [0001] The invention relates to a core part of a cooler or a cooling tower, in particular to a method for combining coils of a counterflow closed cooling tower or a counterflow evaporative cooling (condenser). Background technique [0002] Closed cooling tower or cooling (condenser) is widely used in cooling industrial circulating fluid to discharge waste heat to the air. It is closely related to energy saving and water saving that urgently need to be solved in national economic and social development. [0003] A chiller that cools circulating water with air is often called a cooling tower. The heat transfer in the coil is restricted by the cooling water and there is spray water outside the tube to assist in heat dissipation, which is called a closed cooling tower. When the cooling fluid in the tube is other than water, it is often called an evaporative cooler, and the phase change of the working fluid in the cooling process is called an evaporative condense...
