Technical Field

[0001] This utility model relates to the field of cooling tower technology, specifically a novel composite flow cooling tower. Background Technology

[0002] A Chinese utility model patent with application number 202023104771.5 discloses a square composite flow closed cooling tower; it solves the problem of water freezing in the spray tank in winter by adding a heating structure at the bottom of the cooling tower; however, in the above structure, the heating structure is used directly during winter operation, which results in a waste of resources. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a novel composite flow cooling tower that saves energy and ensures normal operation of the cooling tower.

[0004] To achieve the above objectives, this utility model discloses a novel composite flow cooling tower, which adopts the following technical solution:

[0005] A novel composite flow cooling tower includes a tower body, a fan located at the center of the top of the tower body, first air inlets on both sides of the fan, second air inlets at the lower part of two opposite vertical sidewalls in the tower body, a spray structure in the upper part of the tower body, a condenser heat exchange structure below the spray structure, PVC heat dissipation fins below the condenser heat exchange structure, a heat exchange tube structure in the lower part of the tower body, with both ends of the heat exchange tube structure extending out of the sidewalls of the tower body, one end of the heat exchange tube structure connected to the condenser heat exchange structure, and a water collector in the tower body.

[0006] A further improvement of this novel composite flow cooling tower is that the other end of the heat exchange tube structure is connected to the water inlet structure.

[0007] A further improvement of this novel composite flow cooling tower is that the condenser heat exchange structure includes a heat exchange coil, with an inlet pipe and an outlet pipe respectively at both ends of the heat exchange coil. The inlet pipe is equipped with a water inlet branch pipe, and the heat exchange tube structure is connected to the water inlet branch pipe. Both the inlet pipe and the water inlet branch pipe are equipped with valves.

[0008] A further improvement of this novel composite flow cooling tower is that the spray structure, condenser structure, PVC heat sink, and heat exchange tube structure are provided in two sets, symmetrically distributed on both sides of the tower body.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention features a heat exchange tube structure installed in the lower part of the tower body, which is placed inside the spray water collection tank. The water in the collection tank comes into contact with the heat source entering the tube, and heat is exchanged between the tube and the water.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] like Figure 1As shown, a novel composite flow cooling tower includes a tower body 1, a fan 2 located in the middle of the top of the tower body, first air inlets 3 on both sides of the fan, second air inlets 4 on the lower part of two opposite vertical sidewalls in the tower body, a spray structure 5 in the upper part of the tower body, a condenser heat exchange structure 6 below the spray structure, PVC heat dissipation fins 7 below the condenser heat exchange structure, a heat exchange tube structure 8 in the lower part of the tower body, with both ends of the heat exchange tube structure extending out of the sidewalls of the tower body, one end of the heat exchange tube structure connected to the condenser heat exchange structure, and a water collector 9 also located in the tower body.

[0020] The other end of the heat exchange tube structure is connected to the water inlet structure. This allows the heat source to enter the heat exchange tube. The heat exchange tube structure can be a common coil structure, arranged horizontally.

[0021] Furthermore, the condenser heat exchange structure includes a heat exchange coil, with an inlet pipe 11 and an outlet pipe 10 at each end of the heat exchange coil. The inlet pipe is equipped with a water inlet branch pipe, and the heat exchange tube structure is connected to the water inlet branch pipe 12. Both the inlet pipe and the water inlet branch pipe are equipped with valves.

[0022] The spray structure, condenser structure, PVC heat sink, and heat exchange tube structure are arranged in two sets, symmetrically distributed on both sides of the tower body. The spray structure is located directly below the first air inlet. The second air inlet faces the PVC heat sink.

[0023] The condenser structure has multiple sets of heat exchange coils arranged in a specific pattern. All inlet water pipes are connected to an inlet water tank (not shown in the diagram), and all inlet water pipes are connected to an inlet water sub-tank. A heat source inlet pipe is located on the inlet water tank, which is connected to the heat exchange tube structure.

[0024] A heating structure can also be installed at the bottom of the tower body. When the heat exchange effect is poor, the heating structure can be used to prevent the water in the tank from freezing in winter.

[0025] The working principle of this utility model is as follows: a heat source enters through the inlet pipe, then passes through the heat exchange coil, and exits through the outlet pipe. At this time, cold water is sprayed by the spray structure and comes into contact with the heat exchange coil. Some of the water is evaporated, absorbing heat and thus reducing the temperature of the working fluid in the pipe. The hot air and the unevaporated water are blocked and flow through the PVC heat exchange layer, and are cooled by air intake through the second air inlet. The cold water falls into the water tank at the bottom of the tower. When the temperature is low in winter, the heat source enters the heat exchange tube structure. After the heat source flows, it enters the inlet water pipe and then enters the heat exchange coil. At this time, the inlet pipe valve is closed.

[0026] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
