Description

Technical Field

[0001] The utility model relates to the technical field of cooling towers, in particular to a cross-flow closed cooling tower. Background Art

[0002] A cross-flow closed cooling tower is a device used to cool a fluid at a relatively high temperature. It mainly achieves cooling by drawing in cold air from the outside through a fan and spraying in the cooling tower. However, during operation, the above structure has the problem that the spray water is easily splashed out from the air inlet during the spraying process. In order to solve the above problem, the existing Chinese utility model patent with application number 202120547368.5 discloses a cross-flow closed cooling tower, which is provided with a baffle at the air inlet to prevent the spray water from splashing. However, the lower end of the baffle is not lower than the next air inlet, and there is still the possibility of the spray water splashing, which leaves room for improvement. On the other hand, simply arranging the spray also has the problem of low heat exchange efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a cross-flow closed cooling tower which can prevent the spray water from splashing out and improve the heat exchange effect in view of the shortcomings of the above-mentioned background technology.

[0004] To achieve the above purpose, the utility model adopts the following technical solutions for a cross-flow closed cooling tower:

[0005] A cross-flow closed cooling tower comprises a box body, and a plurality of strip-shaped air inlets arranged in the front-to-back direction on the left and right side walls of the box body. The upper ends of the air inlets face downward and are provided with baffles in the box body, and the lowermost end of the baffle is lower than the upper end of the next air inlet. Two groups of cooling structures are also symmetrically arranged in the box body, and the cooling structure includes a spray pipe, and coils and heat dissipation fillers arranged at intervals are provided below the spray pipe. A water collecting tank is provided below the lowest coil, and the water collecting tank is connected to the spray pipe through a pump body. A water collector is also provided on the side of the cooling structure away from the air inlet, and a fan structure is provided in the middle of the top plate of the box body.

[0006] A further improvement of the cross-flow closed cooling tower of the utility model is that the heat dissipation filler is fixedly connected to the baffle, and the end face of the heat dissipation filler close to the feed inlet is an inclined surface with the same inclination direction as the baffle.

[0007] A further improvement of the cross-flow closed cooling tower of the present invention is that the coils arranged at intervals are connected by connecting pipes, and each group of coils arranged at intervals includes an inlet end pipe and an outlet end pipe, and valves are provided on the inlet end pipe, the outlet end pipe and the connecting pipe.

[0008] A further improvement of the cross-flow closed cooling tower of the utility model is that the water inlet end pipe and the water outlet end pipe pass through the front side wall or the rear side wall of the box body.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] The utility model realizes splash prevention of spray water by arranging a baffle lower than the lower end surface of the next air inlet. At the same time, the inclined design of the side of the heat dissipation filler further improves the splash prevention effect of the spray water. On the other hand, the flow of water in the coil can be adjusted and controlled to improve the heat exchange efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0014] like Figure 1 As shown, a cross-flow closed cooling tower includes a housing 1. Several strip-shaped air inlets 2 arranged in a front-to-rear direction are provided on the left and right side walls of the housing. Baffles 3 are provided on the upper ends of the air inlets, tilting downward toward the housing. The lower end of the baffle is lower than the upper end of the next air inlet. Two cooling structures are also symmetrically arranged within the housing. The cooling structures include spray pipes 4, below which are spaced coils 5 and heat dissipation fillers 6. A water collection tank is provided below the lowest coil, which is connected to the spray pipes via a pump body. A water collector 7 is also provided on the side of the cooling structure away from the air inlet. A fan structure 8 is provided in the middle of the housing's top plate. Existing protective structures can also be provided on the outer sides of the left and right side walls of the housing.

[0015] Furthermore, the heat dissipation filler is fixedly connected to the baffle, and the end surface of the heat dissipation filler near the feed inlet is an inclined surface with the same inclination direction as the baffle. The heat dissipation filler can be fixed to the baffle to further improve the splash-proof effect of the spray water.

[0016] Furthermore, the spaced coils are connected by connecting pipes 9. Each set of spaced coils includes an inlet pipe 10 and an outlet pipe 11. Valves are installed on the inlet and outlet pipes, as well as the connecting pipes. The inlet and outlet pipes pass through the front or rear wall of the box. The appropriate inlet and outlet ports are selected based on the actual heat exchange effect to improve efficiency.

[0017] The working principle of the utility model is as follows: the fan works, sucking cold air from the air inlet into the box, passing through the coil and heat dissipation filler, and then out from the fan. At the same time, the spray pipe sprays water for heat exchange, forming a horizontal closed cooling as a whole.
