Description

Technical Field

[0001] This invention relates to the field of heat exchange equipment technology, specifically to a split-flow heat conduction air-cooled heat exchanger structure. Background Technology

[0002] Air-cooled heat exchangers, as indirect heat exchange devices using air as the medium, expand the heat exchange area through finned tube bundles and are widely used in industrial equipment, special equipment, and other scenarios requiring efficient heat removal. Their typical structure usually includes finned tube bundles, an air-suspended fan to drive forced airflow, and a frame, relying on heat conduction between the hot fluid inside the tubes and the forced-flowing air outside to achieve cooling.

[0003] However, the existing technology has the following shortcomings: Current air cooling heat exchangers achieve cooling of the air suspended inside the fan, but although the current heat exchangers can form heat exchange, the cooling efficiency of the tube bundle and fins by air cooling is relatively slow, making it difficult for the existing air cooling heat exchangers to meet the urgent need for efficient and stable thermal management in high heat load and compact space scenarios.

During use, water is supplied to the heat conduction box from the water storage tank. After the water is preheated, it is sprayed onto the surface of the fins by the spray top, which quickly cools the fins. Excess water flows down and is collected in the distilled water guide hopper for circulation, which not only accelerates the cooling speed but also improves the air exchange efficiency.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: It includes a heat exchanger, with an air suspension fan connected to the heat exchanger. The heat exchanger contains a machine body, a lower connecting frame is located below the machine body, a water storage tank is fixed on the lower connecting frame, a diversion pipe is located beside the water storage tank, and a heat conduction box is installed on the surface of the diversion pipe.

[0031] The present invention will be further described below with reference to the accompanying drawings: Example 1

[0032] As attached Figure 1 To be continued Figure 5 As shown:

[0033] This embodiment provides a split-flow heat conduction air-cooled heat exchanger structure, including a heat exchanger 1, with an air suspension fan 2 connected to the side of the heat exchanger 1. The heat exchanger 1 is characterized by having a body 11 inside, a lower connecting frame 12 below the body 11, a water storage tank 13 fixed on the lower connecting frame 12, a split-flow pipe 15 beside the water storage tank 13, and a heat conduction box 14 mounted on the surface of the split-flow pipe 15. The air suspension fan 2 has a housing 21 inside, a manifold duct 22 above the housing 21, a cold air input pipe 23 and a hot air output pipe 24 respectively mounted on the manifold duct 22, and an elbow connecting pipe 25 connected to the end of the manifold duct 22. The device body 11 contains an outer solid shell 111. An arc-shaped cover 113 is installed at one end of the outer solid shell 111. A lifting frame 112 is installed at the bottom of the outer solid shell 111. A fixed mesh swing frame 114 is connected to the arc-shaped cover 113. A fan 115 covers the fixed mesh swing frame 114. Several tube bundles 116 pass through the outer solid shell 111. A distilled water guide hopper 118 is installed at the bottom of the outer solid shell 111. A spray top 117 is installed on the outer solid shell 111. A swing mesh frame 1111 is installed at the other end of the outer solid shell 111. A locking buckle 1112 is fixed to the swing mesh frame 1111. Several fins 1113 are installed inside the outer solid shell 111. An even number of inlet and outlet pipes 1161 are connected inside the tube bundles 116. The spray top 117 is equipped with a top cover 1171. An even number of side filter blocks 1172 are fixed on the top cover 1171. Water pipes 1173 are installed on the outer surface of the top cover 1171. A distribution box 1174 is fixed on the inner surface of the top cover 1171. Several cap-shaped water diffusers 1175 are installed on the distribution box 1174.

[0034] Furthermore, a dustproof net can be installed on the fixed net frame 114 installed on the arc-shaped cover 113, thereby covering the rear of the fan 115 with the dustproof net, thus ensuring the airflow while reducing the adhesion of foreign objects and dust to the fins or tube bundle.

[0035] Furthermore, the manifold 22 and elbow connecting pipe 25 have the same structure as the branch pipe 15, while hot air is input and output in the cooling manifold 22, thereby reducing the number of pipes and making the pipe layout clear.

[0036] Furthermore, a dustproof net can also be installed on the swing frame 1111, covering the other side of the device body 11. After the locking port 1112 is opened, it can swing in one direction with the device body 11 to complete the opening.

[0037] Furthermore, the distilled water guide 118 is located at the bottom of the device body 11, so that after the water flows into contact with the fins 1113, the evaporation and excess water are collected, the water flow is guided, and the water is collected in the water storage tank 13 for recycling.

[0038] Furthermore, the cap-shaped water diffuser 1175 is connected to the distribution box 1174 through a pipe. With the input of water flow in the distribution box 1174, the water flow spreads in an umbrella shape and sprays onto the surface of the fins 1113 below, accelerating the cooling of the tube bundle 116 by the fins 1113 under the contact of moisture and air.

[0039] The specific working principle is as follows:

[0040] In this invention, the air-suspended fan 2 is nested and fixed within the lower connecting frame 12, parallel to the device body 11. A water storage tank 13 is mounted on the surface of the lower connecting frame 12. A heat conduction box 14 is disposed on the diversion pipe 15 and connected to the air-suspended fan 2 with the assistance of the elbow connecting pipe 25. A hot air output pipe 24 outputs from the air-suspended fan 2, moves within the manifold duct 22 and the elbow connecting pipe 25, and enters the tube bundle 116 within the outer solid shell 111. Heat is diffused from the tube bundle 116 to the fins. Above the fin 1113, the heat conduction box 4, in conjunction with the water storage tank 13, supplies water, allowing the water to flow into the spray top 117. After entering through the water supply pipe 1173 inside the top cover 1171, the water enters the distribution box 1174, which, in conjunction with the cap-shaped water diffuser 1175, sprays the fin 1113. During spraying, steam is generated, which is blown by the fan 115 to accelerate heat dissipation. The cooled air then flows back into the casing 21 through the cold air input pipe 23, achieving rapid cooling of the air. Example 2

[0041] As attached Figure 6 To be continued Figure 8 As shown:

[0042] The water storage tank 13 contains a tank body 131, with an inlet pipe 132 installed on top of the tank body 131, a manifold pipe 134 installed on one side of the tank body 131, and an outlet pipe 133 installed on the other side of the tank body 131. The heat conduction box 14 contains a water box 141, with an arc-shaped groove 142 formed at the bottom of the water box 141. A box cover 143 is installed on the surface of the water box 141, and a first pump 144 and a second pump 145 are respectively installed on the box cover 143. The diversion pipe 15 contains a cylindrical shell 151, with an inner partition 152 fixed in the center of the cylindrical shell 151. An air outlet pipe 153 is installed above the inner partition 152, and an air inlet pipe 154 is installed below the inner partition 152.

[0043] Furthermore, the arc-shaped groove 142 at the bottom of the water box 141 is mainly attached to the surface of the shell 151. The heat carried by the air outlet pipe 153 heats the water flow inside the water box 141, thereby raising the water temperature. During the spraying process, the fins 1113 form evaporation, allowing the moisture to accelerate the heat dissipation.

[0044] Furthermore, the inner baffle 152 is made of heat-insulating material, dividing the shell 151 into two parts to prevent the high temperature inside the outlet pipe 153 from flowing inside and affecting the air temperature of the inlet pipe 154 after cooling.

[0045] Furthermore, the first pump 144 is mainly used to connect with the water outlet pipe 133 to pump the water in the water storage tank 13 to provide continuous water supply, while the second pump 145 is connected to the water supply pipe 1173 on the top of the sprayer through a pipeline to complete the water supply to the distribution box 1174.

[0046] The specific working principle is as follows:

[0047] This invention uses the water outlet pipe 133 on the housing 131, with the assistance of the first pump 144, to regulate the water flow, allowing the water to enter the water box 141. The water box 141, in conjunction with the arc-shaped groove 142 at the bottom, is fixed to the air outlet pipe 153 on the surface of the cylinder shell 151. The high temperature of the air outlet pipe 153 preheats the water in the water box 141. The preheated water, with the assistance of the second pump 145, is connected to the spray top 117. While spraying, some of the water evaporates, forming moisture that falls down the fins and is finally collected by the distilled water guide 118. Under the action of the manifold 134, it re-enters the housing 131, thus forming a water circulation and saving water consumption.
