Description

Technical Field

[0001] The utility model relates to the technical field of counterflow cooling towers, in particular to a counterflow cooling tower with an external heat dissipation flow channel. Background Technique

[0002] The counterflow cooling tower is a common heat dissipation device, which is widely used in industrial refrigeration, air conditioning systems, power plants and other places. Its working principle is to introduce hot water from the top, so that the water contacts the upward flowing air in a countercurrent manner, thereby realizing heat exchange.

[0003] By means of an external heat dissipation flow channel, the heat dissipation efficiency of the cooling tower can be improved. Subsequently, a counterflow cooling tower with an external heat dissipation flow channel is proposed. For example, in the prior art, Chinese Patent Publication No. "CN115183598A" discloses a counterflow cooling tower, which includes a tower body, heat exchange pipes arranged inside the tower body, a water cooling component and an air cooling component. A water storage pool is arranged on the tower body below the air inlet. The water cooling component includes a water pump. The water inlet of the water pump is communicated with the water storage pool, and the water outlet is communicated with the water storage pool through an endothermic flow channel and a heat dissipation flow channel in sequence. The endothermic flow channel is arranged directly above the heat exchange pipe in a fitting manner, and the heat dissipation flow channel is arranged outside the tower body. The structure of this counterflow cooling tower is reasonable. By guiding the flow path of the cooling water through the endothermic flow channel, the utilization rate of the cooling water is improved, the number of times of circulating flow of the cooling water is reduced, and the heat exchange between the cooling water and the air entering the tower body from the outside is prevented. The heat absorbed by the cooling water is released to the outside by using the heat dissipation flow channel, so as to increase the heat exchange amount and improve the cooling efficiency, thereby reducing the equipment operation time and achieving energy conservation.

[0004] In specific operations, the water pump is connected to the heat dissipation flow channel through a water delivery pipe. However, considering the situation that the environmental temperature where the cooling tower is located is relatively low or the fluid temperature in the cooling tower needs to be maintained within a certain high or low temperature range, there is no measure to insulate the water delivery pipe, which may cause the internal of the cooling tower pipeline to freeze and solidify. Content of the Utility Model

[0005] The purpose of the utility model is to solve the above-mentioned disadvantages in the prior art that there is no measure to insulate the water delivery pipe, which affects the normal use of the cooling tower, and to propose a counterflow cooling tower with an external heat dissipation flow channel.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] Design a counterflow cooling tower with an external heat dissipation flow channel, including a tower body and a water pump. An endothermic flow channel is arranged inside the tower body, and heat dissipation flow channels are arranged outside both sides of the tower body. The outer wall of the endothermic flow channel is arranged in a fitting manner with the heat dissipation flow channel through a fixing frame;

[0008] A water collecting tank is provided at the bottom of the tower body. The input end of the water pump is communicated with the water collecting tank, and its output end is communicated with the heat dissipation flow channel through a water delivery pipe.

[0009] Among them, there are a pair of water delivery pipes. A filter plate is arranged between the pair of water delivery pipes through a connecting pipe, and a heat preservation cotton is coated on its periphery through a fixing component.

[0010] Furthermore, both ends of the connecting pipe are fixedly connected with the water delivery pipe through connecting flanges. A convex portion is extended from the periphery of the connecting pipe. The filter plate is slidably connected to the inside of the convex portion through a chute, and a sealing strip is arranged between the chute and the side surface of the filter plate.

[0011] Furthermore, the fixing component includes a clamp. The clamp is composed of a pair of hoop bodies. The pair of hoop bodies are sleeved on the water delivery pipe, and one end of them is hinged and rotated, and the other end is fixed through a fixing piece.

[0012] Furthermore, both ends of the hoop body extend inwards to form clamping portions, and the connecting flanges are avoided through the clamping portions. A plurality of teeth are arranged on the outer wall of the clamping portion. The pair of clamping portions are closed and the heat preservation cotton is fastened through the teeth on both sides.

[0013] Furthermore, a convex portion is arranged on the inner wall of the hoop body at the top, and the filter plate is pressed tightly through the convex portion when it is closed.

[0014] Furthermore, the fixing piece includes a screw rod and a wing nut. Fixing portions are arranged on the sides of the pair of hoop bodies. An activity groove is arranged on the end face of the fixing portion. One end of the screw rod is rotatably connected in the activity groove, and the other end is movably connected in another activity groove. The other end of the screw rod is threadedly connected with the wing nut, and the wing nut presses tightly against the fixing portion.

[0015] The countercurrent cooling tower with an external heat dissipation flow channel proposed by the present utility model has the beneficial effects that: on the one hand, through the arrangement of the heat absorption flow channel and the heat dissipation flow channel, the cooling of the cooling water can be accelerated, and on the other hand, the cooling water can be reused. And through the fixing piece, the heat preservation cotton and the filter plate can be fixed, which not only avoids affecting the normal use when the environment temperature where the cooling tower is located is relatively low, but also can prevent the flow channel from being blocked due to impurities in the cooling water. The structure is simple, the operation is convenient, and the practicability is strong. BRIEF DESCRIPTION OF THE DRAWINGS
