Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, and in particular to a dry cooler heat dissipation unit. Background Technology

[0002] In existing technologies, a dry cooler is a cooling device that utilizes air for heat dissipation. Its core working principle is to transfer the heat of the internal circulating fluid to the outside air through a heat exchanger, thereby achieving cooling. The core of the dry cooler's heat dissipation unit is to achieve waterless cooling through heat exchange between air and fluid. It mainly consists of heat dissipation coils, fans, and air ducts, and is suitable for scenarios with water shortages or high environmental protection requirements.

[0003] Existing dry coolers mainly use air ducts to guide airflow and achieve strong air convection, thereby achieving rapid cooling of the heat dissipation coils. However, in order to cover the heat dissipation coils, the diameter of the air duct itself is relatively large, which leads to a relatively low airflow velocity. In order to ensure the heat dissipation effect of the heat dissipation coils, the fan speed must be higher. The higher the fan speed, the greater the energy consumption. Although it has a more obvious advantage than traditional evaporative coolers, its effect on the heat dissipation coils is relatively weak. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dry cooler heat dissipation unit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The dry cooler heat dissipation unit includes a heat dissipation unit 1 and a heat dissipation unit 2 with the same structure. The heat dissipation unit 1 includes a refrigerant heat dissipation pipe and an internal cooling pipe. A heat dissipation outer cylinder is fixedly installed on the outer wall of the refrigerant heat dissipation pipe, and an installation frame is fixedly installed on the top of the heat dissipation outer cylinder. Multiple heat dissipation fan groups that guide high-speed airflow into the heat dissipation outer cylinder are fixedly installed inside the installation frame. The built-in cooling pipes are arranged in multiple equidistant sections, with an exhaust mounting cylinder and an exhaust bend pipe connected to each end. An end mounting plate one is fixedly connected inside the exhaust mounting cylinder, and an end mounting plate two is fixedly connected inside the exhaust bend pipe. The end mounting plate one and the end mounting plate two are used to seal the refrigerant heat dissipation pipes.

[0006] As a further improvement of this utility model: multiple annular heat dissipation baffles are welded at equal intervals on the inner wall of the heat dissipation outer cylinder, and an exhaust window is provided at the bottom of the outer wall of the heat dissipation outer cylinder between two adjacent annular heat dissipation baffles, and a filter screen is fixedly installed at the bottom of the exhaust window.

[0007] As a further improvement of this utility model: multiple multi-arm support frames are fixedly installed at equal intervals inside the heat dissipation pipe of the refrigerant, and multiple built-in cooling pipes are fixedly connected to the multi-arm support frames.

[0010] As a further embodiment of this utility model: a plurality of sealing mounting cylinders for installing built-in cooling pipes are fixedly connected to one side of the end mounting plate two, and a sealing cover is threaded onto the outer wall of the sealing mounting cylinder.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Dry cooler heat dissipation unit, such as Figures 1 to 6 As shown, it includes heat dissipation unit 1 and heat dissipation unit 2 with the same structure. Heat dissipation unit 1 includes a refrigerant heat dissipation pipe 103 and an internal cooling pipe 116. The outlet of heat dissipation unit 1 and the inlet of heat dissipation unit 2 are connected to form a heat dissipation unit. Multiple heat dissipation units are connected to form a heat dissipation unit. The refrigerant heat dissipation pipe 103 and the internal cooling pipe 116 work together to dissipate heat from both inside and outside the refrigerant of the dry cooler, thereby improving the heat dissipation speed and effect of the refrigerant and reducing the energy consumption of the heat dissipation unit.

[0020] A heat dissipation outer cylinder 104 is fixedly installed on the outer wall of the refrigerant heat dissipation pipe 103. A mounting frame 105 is fixedly installed on the top of the heat dissipation outer cylinder 104. Multiple cooling fan groups 106 that introduce high-speed airflow into the heat dissipation outer cylinder 104 are fixedly installed inside the mounting frame 105.

[0021] Multiple annular heat dissipation baffles 118 are welded at equal intervals to the inner wall of the heat dissipation outer cylinder 104. The inner wall of the annular heat dissipation baffles 118 is welded to the outer wall of the refrigerant heat dissipation pipe 103, dividing the inner cavity of the heat dissipation outer cylinder 104 into multiple heat dissipation cavities.

[0022] An exhaust window is provided at the bottom of the outer wall of the heat dissipation outer cylinder 104 between two adjacent annular heat dissipation partitions 118, and a filter screen 119 is fixedly installed at the bottom of the exhaust window; and multiple air inlet slots are provided at the top of the outer wall of the heat dissipation outer cylinder 104 between two adjacent annular heat dissipation partitions 118; the total air inlet area of ​​the air inlet slots is greater than the exhaust area of ​​the exhaust window, and the exhaust area of ​​the exhaust window is greater than the cross-sectional area of ​​the air flow of the heat dissipation cavity.

[0023] The cooling fan assembly 106 introduces high-velocity airflow through the air intake slot. Under the action of the cooling cavity, the airflow further increases in velocity and is then discharged through the exhaust window. During this process, the high-velocity air continuously absorbs heat from the refrigerant from the walls of the annular heat dissipation baffle 118 and the refrigerant heat dissipation pipe 103, thereby reducing the temperature of the refrigerant.

[0024] A T-shaped tee connector 107 is fixedly installed at one end of the refrigerant heat dissipation pipe 103. A digital flow meter 108 is fixedly installed inside the branch pipe of the tee connector 107 to measure the flow rate of the refrigerant introduced into the refrigerant heat dissipation pipe 103 per unit time.

[0025] A vacuum mounting cylinder 109 is fixedly installed at the end of the tee connector 107 away from the refrigerant heat dissipation pipe 103. The vacuum mounting cylinder 109 is a variable diameter cylinder, with a smaller diameter at the end near the tee connector 107, and an end mounting plate 120 integrally formed inside.

[0026] Multiple air inlet holes are provided on the side of the end mounting plate 120 away from the tee connector 107. An internal thread groove is provided on the inner wall of the air inlet hole near the end of the tee connector 107. The inner wall of the air inlet hole and the end of the end mounting plate 120 near the high-flow fan 114 are both chamfered to facilitate the air introduced by the high-flow fan 114 to enter the air inlet hole.

[0027] A dust filter screen 110 is fixedly installed at the other end of the air extraction installation cylinder 109, and a high-flow fan 114 is fixedly installed inside the end. The high-flow fan 114 draws air from the outside, and the dust filter screen 110 filters the air to ensure the cleanliness of the airflow.

[0028] The other end of the refrigerant heat dissipation pipe 103 is fixedly installed with a T-shaped three-way connecting pipe 111. A temperature sensor 112 is fixedly installed inside the branch pipe of the three-way connecting pipe 111 to measure the temperature of the refrigerant discharged from the refrigerant heat dissipation pipe 103.

[0029] The end of the tee connector 211 away from the refrigerant heat dissipation pipe 103 is fixedly installed with a downwardly bent exhaust bend 113. The end of the exhaust bend 113 near the tee connector 211 has an end mounting plate 221 integrally formed inside.

[0030] On the side of the end mounting plate 2 121 away from the three-way connecting pipe 2 111, there are multiple sealing mounting cylinders 122 corresponding to the air inlet holes. The outer wall of the sealing mounting cylinder 122 is threaded with a sealing cover cylinder 123, and the inside of the sealing cover cylinder 123 is also provided with a sealing rubber ring.

[0031] The built-in cooling pipes 116 are set at equal intervals of seven (the specific number can be adjusted as needed). Multiple multi-arm support frames 115 are fixedly installed at equal intervals inside the refrigerant heat dissipation pipe 103. The seven built-in cooling pipes 116 are fixedly connected to the multi-arm support frames 115. The multi-arm support frames 115 do not affect the flow of refrigerant inside the refrigerant heat dissipation pipe 103.

[0032] One end of the built-in cooling pipe 116 is threaded into the internal thread groove of the air intake hole, and the other end passes through the sealing mounting cylinder 122 and extends into the exhaust bend 113. The sealing rubber ring is fitted onto the outside of the built-in cooling pipe 116.

[0033] The inner wall of the built-in cooling pipe 116 is integrally formed with multiple built-in heat dissipation fins 117 at equal intervals. A heat dissipation gap is opened in the middle of the built-in heat dissipation fins 117 to increase the heat dissipation effect of the built-in cooling pipe 116. The inner diameter of the built-in cooling pipe 116 is the same as the inner diameter of the air inlet hole, and the outer diameter is the same as the inner diameter of the sealing mounting cylinder 122. Together with the end mounting plate 120 and the end mounting plate 121, it is used to seal the refrigerant heat dissipation pipe 103 to prevent refrigerant leakage.

[0034] The lower ends of both ends of the refrigerant heat dissipation pipe 103, the lower end of the exhaust mounting cylinder 109 near the tee connecting pipe 107, and the lower end of the exhaust bend 113 near the tee connecting pipe 111 are all fixedly snapped with bearing arms 102, and the bottom ends of the multiple bearing arms 102 are fixedly installed with bearing base plates 101.

[0035] Heat dissipation unit 1 and heat dissipation unit 2 have the same structure, the difference being that the branch pipes of the tee connector 107 and the tee connector 111 of the two are oriented in opposite directions. Both heat dissipation unit 1 and heat dissipation unit 2 are equipped with sub-controllers to receive the detection values ​​fed back by the digital flow meter 108 and the temperature sensor 112; at the same time, they control the speed (flow rate of the introduced air) of the cooling fan group 106 and the high-flow fan 114 (execution unit). Multiple sub-controllers are controlled by the main controller. The main controller sends instructions to the sub-controllers based on the data fed back by the sub-controllers, and the sub-controllers control the corresponding execution units to adjust the speed, thereby achieving the purpose of quickly adjusting the heat dissipation effect of the refrigerant.

[0036] Working principle: Reference Figures 1 to 6 Assemble the device as shown in the figure; and connect it with other units of the dry cooler, such as the surface cooler, the refrigerant circulation pump, etc. In use, the refrigerant is introduced by a refrigerant circulation pump through the three-way connecting pipe 107 of the first heat dissipation unit 1, and output by the three-way connecting pipe 111 of the last heat dissipation unit 2. During the refrigerant circulation process, the refrigerant flow rate is calculated by a digital flow meter 108, and the temperature of the refrigerant when it is output from each heat dissipation unit (heat dissipation unit 1 and heat dissipation unit 2) is measured by a temperature sensor 112. The sub-controllers feed back the detected values ​​to the main controller, which sends different instructions to the corresponding sub-controllers based on the feedback data. The sub-controllers control the corresponding execution units (cooling fan group 106 and high-flow fan 114) to adjust the airflow introduction speed, thereby realizing stepped cooling control of the refrigerant and reducing the overall energy consumption of the device.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
