Description

Technical Field

[0001] This utility model belongs to the field of refrigeration equipment technology, and in particular relates to an evaporator tube with internal surface heat exchange. Background Technology

[0002] Evaporator tubes are the core components of a refrigeration system that achieve the cooling effect. Their function is to absorb a large amount of heat by boiling and evaporating liquid refrigerant in a low-pressure environment inside the tube, thereby lowering the temperature of the surrounding air or liquid. Depending on the cooling medium, they are mainly divided into finned tube and bare tube types for cooling air, and shell and tube and plate types for cooling liquids. However, evaporator tubes still have the following drawbacks in practical use: When the evaporator tube is in operation, it directly uses the heat exchange structure on the periphery to exchange heat and then performs the cooling work. However, the heat exchange efficiency is limited during the cooling process, resulting in an insufficient heat exchange area and affecting the overall heat exchange efficiency of the evaporator tube. Secondly, the evaporator tube is installed directly using the installation equipment during operation. During installation, it is directly attached to the flat surface of the equipment. After being attached, external heat can easily enter the evaporator tube, affecting the cooling effect. Utility Model Content

[0003] The purpose of this utility model is to provide an evaporator tube with internal surface heat exchange. By setting up an evaporator tube body, heat exchange components, heat conduction plate and heat insulation sheet, it solves the problems that the heat exchange area of ​​the evaporator tube is not large enough, which affects the overall heat exchange efficiency of the evaporator tube, and the heat insulation effect of the evaporator tube is not good enough, which affects the cooling effect.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an evaporator tube with internal surface heat exchange, comprising an evaporator tube body, heat exchange components, heat-conducting plates, and heat insulation sheets. The heat exchange components are fixed in a ring array on the inner wall of the evaporator tube body. Connecting plates are fixed to the periphery of the evaporator tube body, and a heat insulation sheet is fixed to the side of the connecting plates away from the evaporator tube body. Heat-conducting plates are symmetrically fixed to the periphery of the evaporator tube body, positioned away from the heat insulation sheets. The length direction of the heat-conducting plates is the same as the length direction of the evaporator tube body. The evaporator tube body is used to transport refrigerant. The ring array of heat exchange components on its inner wall enhances internal heat exchange efficiency. External heat-conducting plates are symmetrically fixed on both sides of the tube wall, responsible for absorbing heat from the equipment and conducting it to the evaporator tube. The heat insulation sheets are connected to the outer wall of the evaporator tube through connecting plates, effectively blocking the entry of external ambient heat and ensuring that the refrigeration process mainly absorbs heat from inside the equipment.

[0005] Furthermore, heat exchange fins are fixed in a ring array on the inner wall of the evaporator tube body. The heat exchange fins are arranged between adjacent heat exchange components. The inner wall of the evaporator tube is also provided with a ring array of heat exchange fins located between the heat exchange components, which further expands the heat exchange area, strengthens convective heat transfer, and improves the overall cooling performance.

[0006] Furthermore, the heat exchange assembly includes multiple parallel heat exchange plates, all of which are fixed on the inner wall of the evaporator tube body. The heat exchange plates are fixed between adjacent heat exchange fins. The heat exchange assembly is composed of multiple parallel heat exchange plates installed between adjacent heat exchange fins to jointly enhance the heat exchange interface, promote refrigerant evaporation and heat absorption, and improve refrigeration efficiency.

[0007] Furthermore, the heat exchange assembly also includes a fixing strip and a connecting strip. All the heat exchange plates are fixed with a fixing strip on the side away from the inner wall of the evaporator tube body. The fixing strip is fixed with a connecting strip on the side away from the heat exchange plate. The outer ends of the heat exchange plates are connected as one unit by the fixing strip. The connecting strip is provided on the outside of the fixing strip, which plays a role in overall reinforcement and conduction, ensuring the structural stability of the heat exchange assembly and uniform heat transfer.

[0008] Furthermore, a filler strip is fixed between each of the heat-conducting plates and the evaporator tube body. A guide strip is fixed on the side of the heat-conducting plate away from the evaporator tube body. The heat-conducting plate and the outer wall of the evaporator tube are connected by the filler strip to enhance heat conduction. The guide strip on the outside of the heat-conducting plate is used to improve the fit with the surface of the equipment and optimize thermal contact.

[0009] Furthermore, the heat insulation sheet is hollow inside, and an outer fixing plate is fixed on the side of the heat insulation sheet away from the connecting plate. The outer fixing plate has uniformly opened fitting grooves on the side away from the heat insulation sheet. The heat insulation sheet has a hollow structure to reduce heat conduction. The outer fixing plate with fitting groove is installed on its outer side. The groove structure enhances the adhesion with the external fixing material, thereby improving the installation stability and heat insulation effect.

[0010] This utility model has the following beneficial effects: This invention solves the problem of insufficient heat exchange area in the evaporator tube, which affects the overall heat exchange efficiency, by setting up an evaporator tube body, heat exchange components, and heat-conducting plates. When the evaporator tube body is attached to the working surface by an external bonding device, two heat-conducting plates are attached to the plane of the working device. This allows the heat from the working device to be transferred to the evaporator tube body through the heat-conducting plates and filler strips, and then transferred to the internal heat exchange fins and heat exchange plates. After the refrigerant passes through the evaporator tube body, it undergoes heat exchange through the heat exchange fins and heat exchange plates, causing the refrigerant to evaporate and cool. This allows the refrigerant to fully evaporate and exchange heat in the evaporator tube body, resulting in a larger heat exchange area and increased overall heat exchange efficiency.

[0011] This invention solves the problem of insufficient heat insulation of the evaporator tube affecting the cooling effect by setting up an evaporator tube body and a heat insulation sheet. After the heat conduction plate is attached to the working equipment, it is attached to the outer fixing plate with adhesive tape, which makes the outer fixing plate, heat insulation sheet and connecting plate bend. Then, it is attached to the use equipment with adhesive tape and installed and fixed on the use equipment. Because the heat insulation sheet is hollow inside, it reduces the transfer of external heat to the evaporator tube body, prevents the reduction of cooling efficiency, makes the heat insulation of the evaporator tube better, and ensures the cooling effect.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0016] Please see Figure 1-5This utility model is an evaporator tube with internal surface heat exchange, including an evaporator tube body 1, a heat exchange component 2, a heat-conducting plate 3, and a heat insulation plate 4. The heat exchange component 2 is fixed in a ring array on the inner wall of the evaporator tube body 1. The evaporator tube body 1 transports refrigerant through it, and the heat exchange component 2 evaporates the refrigerant in the evaporator tube. A connecting piece 402 is fixed on the periphery of the evaporator tube body 1, and the evaporator tube body 1 is connected to the heat insulation plate 4 through the connecting piece 402. The heat insulation plate 4 is fixed on the side of the connecting piece 402 away from the evaporator tube body 1. The heat insulation plate 4 separates the evaporator tube body 1 from the external environment, so that more of the heat absorbed during the evaporation of the refrigerant comes from the inside of the equipment that needs to be cooled. The heat-conducting plate 3 is symmetrically fixed on the periphery of the evaporator tube body 1. The heat-conducting plate 3 transfers the heat in the equipment to the evaporator tube body 1. The heat-conducting plate 3 is set away from the heat insulation plate 4, and the length direction of the heat-conducting plate 3 is the same as the length direction of the evaporator tube body 1, so that cooling is performed during operation.

[0017] Specifically, heat exchange fins 101 are fixed in a ring array on the inner wall of the evaporator tube body 1. The heat exchange fins 101 are arranged between adjacent heat exchange components 2. The evaporator tube body 1 cools the equipment in the refrigerant cooling process through the heat exchange fins 101.

[0018] Furthermore, the heat exchange assembly 2 includes multiple parallel heat exchange plates 201, all of which are fixed on the inner wall of the evaporator tube body 1. The heat exchange plates 201 are fixed between adjacent heat exchange fins 101. After heat exchange, the heat exchange assembly 2 further increases the heat exchange efficiency through the heat exchange plates 201, thus ensuring the cooling efficiency of the evaporator tube.

[0019] Furthermore, the heat exchange assembly 2 also includes a fixing strip 202 and a connecting strip 203. The fixing strip 202 is fixed on the side of all heat exchange plates 201 away from the inner wall of the evaporator tube body 1. The connecting strip 203 is fixed on the side of the fixing strip 202 away from the heat exchange plate 201. Through the cooperation of the fixing strip 202 and the connecting strip 203, all heat exchange plates 201 are connected and set together.

[0020] Furthermore, each heat-conducting plate 3 and the evaporator tube body 1 are jointly fixed with a filler strip 302. A guide strip 301 is fixed on the side of the heat-conducting plate 3 away from the evaporator tube body 1. The heat-conducting plate 3 and the evaporator tube body 1 are connected together by the filler strip 302 and are attached to the corresponding bonding plane by the guide strip 301 to ensure the bonding degree.

[0021] The operation process of this embodiment is as follows: During operation, when the evaporator tube body 1 is attached to the working surface by an external bonding device, two heat-conducting plates 3 are attached to the plane of the working device, so that the heat of the working device is attached to the evaporator tube body 1 through the heat-conducting plates 3 and the filler strip 302, and is transferred to the internal heat exchange fins 101 and heat exchange plates 201 on the evaporator tube body 1. After the refrigerant passes through the evaporator tube body 1, it exchanges heat through the heat exchange fins 101 and heat exchange plates 201, so that the refrigerant evaporates and cools, and the refrigerant fully evaporates and exchanges heat in the evaporator tube body 1. Specific Implementation Example 2

[0022] Please see Figure 1 , 2 6. Based on the specific embodiment 1, the heat insulation sheet 4 is hollow inside. An outer fixing piece 401 is fixed on the side of the heat insulation sheet 4 away from the connecting piece 402. The outer fixing piece 401 is evenly provided with a bonding groove 4011 on the side away from the heat insulation sheet 4. The heat insulation sheet 4 is hollow inside, which isolates external heat. The bonding groove 4011 on the outer fixing piece 401 increases the bonding tightness with the external bonding device.

[0023] The operation process of this embodiment is as follows: During operation, after the heat conduction plate 3 is attached to the working equipment, it is attached to the outer fixing plate 401 by the adhesive tape, so that the outer fixing plate 401, the heat insulation plate 4 and the connecting plate 402 are bent, and then attached to the use equipment by the adhesive tape, and installed and fixed on the use equipment. The heat insulation plate 4 is hollow inside, which reduces the transfer of external heat to the evaporator tube body 1 and prevents the cooling efficiency from being reduced.
