Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1-2, a coil for cooling equipment includes a converging housing 3, and a liquid inlet 1 and a liquid outlet 2 located at two ends of the converging housing 3, wherein a plurality of uniformly arranged tubes 4 are arranged in the converging housing 3, two ends of each tube 4 are respectively welded and sealed with the liquid inlet 1 and the liquid outlet 2, the tubes 4 have a certain inclination angle, one end close to the liquid outlet 2 is low, and the other end close to the liquid inlet 1 is high; a spraying device 7 communicated with a water inlet pipe 6 is arranged above the confluence shell 3, and an air outlet pipe network 11 connected with an air inlet pipe 10 is arranged below the confluence shell 3;

in a specific embodiment, the inclination angle be 5, the coil pipe height of the inclination angle decision of pipe, the height of equipment, whether smooth and easy outflow of the fluid in the pipe of considering simultaneously reduces on-way resistance, and 5 degrees that this application adopted are through long-term experiment and experience to obtain, and the inside hydrops caused the possibility that the pipe freezes when very effectively avoiding shutting down in winter.

More specifically, the cross-sectional shape of the tube 4 is a vertical ellipse, as shown in fig. 3, when water flows down uniformly on the tube wall, the whole tube wall has no dead angle due to the action of wind, so that the water can act uniformly on the tube wall and perform heat exchange sufficiently, the main dimension is the major diameter (31.75) and the minor diameter (21.6), and the perimeter of the ellipse obtained by accurately calculating the major dimension is the longest, which means that the surface area of the coil is the largest, and heat exchange can be performed more sufficiently.

In one embodiment, based on long-term experience and equipment performance tests, it is found that the ellipse with the diameter of 26.7 mm and the length of the ellipse changed into 31.79 x 21.6 mm has the longest perimeter, which means the cross-sectional area is the largest, and the heat dissipation area is the largest and the heat exchange is the best under the condition of the same fluid volume. More effective energy saving.

Furthermore, a bracket 5 is arranged at the middle part of the confluence shell 3, and the pipes 4 are supported by the bracket 5, so that the deformation of the pipes under the action of self gravity is prevented, and the flow of liquid in the pipes is prevented from being influenced;
