Abstract
Description
Technical Field
[0001] This utility model relates to the field of evaporator technology, and in particular to a bonded evaporator. Background Technology
[0002] Direct-cooling refrigerators typically use adhesive-bonded evaporators, where the evaporator coils are bonded to a heat exchange plate using hot melt adhesive. The heat exchange plate is then bonded to the refrigerator liner, and foam is used to fill the space between the liner and the front panel. To prevent the coils from easily detaching from the heat exchange plate due to only one side being bonded, existing technologies use a heat exchange plate and a pressure plate to press the coils firmly into contact with the heat exchange plate, thus preventing detachment.
[0003] However, in existing technologies, the gap between the heat sink and the pressure plate is small after they are bonded together, which prevents the formaldehyde produced by the adhesive from evaporating in time. After long-term use, this can easily affect the health of users. Furthermore, since the heat sink and the pressure plate are bonded together, the quick disassembly of the coil is not ideal when it is damaged during use. Therefore, it is necessary to provide a bonding-type evaporator to solve the above problems. Utility Model Content
[0004] The main objective of this invention is to provide a bonding-type evaporator that can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A bonding evaporator includes a heat dissipation plate, a coil is provided on the top of the heat dissipation plate, and a connecting component is provided on one side of the top of the heat dissipation plate.
[0007] The connecting assembly includes a threaded connector, the top of which is provided with a mounting base plate and a limiting support sleeve, and the middle of the limiting support sleeve is provided with a connecting threaded rod. The top of the connecting threaded rod is provided with a connecting nut, and the outside of the connecting threaded rod is provided with a mounting base. The bottom of the connecting nut is provided with a pressure plate, and a rubber protective pad is provided below the pressure plate.
[0008] Preferably, the threaded connector is connected to the heat sink by bolts, and there are four threaded connectors, which are symmetrically distributed in the middle of the four corners of the heat sink. The bottom end of the threaded connector penetrates the bottom of the heat sink, and a threaded hole is opened in the middle of the threaded connector.
[0009] Preferably, the top of the threaded connector is bolted to a mounting base plate, and a limiting support sleeve is fixedly connected to the top of the mounting base plate. The limiting support sleeve is correspondingly arranged with the threaded connector, and the top of the limiting support sleeve is horizontally arranged with the top of the coil.
[0010] Preferably, a connecting threaded rod is inserted into the middle of the limiting support sleeve, and the connecting threaded rod passes through the limiting support sleeve and is connected to the inside of the threaded connection seat. A connecting nut is fixedly connected to the top of the connecting threaded rod, and a mounting seat is threadedly connected to the outer wall of the connecting threaded rod. The connecting nut is located above the mounting seat.
[0011] Preferably, the mounting base is connected to the pressure plate by bolts, and there are four mounting bases, which are symmetrically distributed in the middle of the four corners of the pressure plate. A rubber protective pad is connected to the bottom of the pressure plate, and an arc-shaped groove is opened at the bottom of the rubber protective pad. The arc-shaped groove is corresponding to the coil, and a threaded groove is opened at one end of the arc-shaped groove. A connecting threaded rod is inserted into the middle of the threaded groove.
[0012] Preferably, the heat sink and the coil are connected together by adhesive. The pressure plate has a ventilation groove in the middle, and there are multiple ventilation grooves, which are evenly distributed in the middle of the pressure plate. The ventilation grooves penetrate the pressure plate. The rubber protective pad and the pressure plate are both provided with ventilation grooves in the middle.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] In this invention, a connecting component is used to position and connect the heat sink and the pressure plate. A connecting threaded rod passes through the mounting base and connects to the inside of the threaded connection seat, thus completing the connection between the pressure plate and the heat sink. This facilitates the subsequent disassembly of the pressure plate and the disassembly and maintenance of the coil, improving the ease of use of the device.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a bonding evaporator includes a heat dissipation plate 1, a coil 2 is provided on the top of the heat dissipation plate 1, and a connecting component 3 is provided on one side of the top of the heat dissipation plate 1.
[0022] The connecting assembly 3 includes a threaded connector 4. The top of the threaded connector 4 is provided with a mounting base plate 5 and a limiting support sleeve 6. A connecting threaded rod 7 is located in the middle of the limiting support sleeve 6. A connecting nut 8 is located at the top of the connecting threaded rod 7.

A pressure plate 13 is located at the bottom of the connecting nut 8, and a rubber protective pad 11 is located below the pressure plate 13. The threaded connector 4 is connected to the heat sink 1 by bolts. There are four threaded connectors 4, symmetrically distributed at the four corners of the heat sink 1. The bottom end of the threaded connector 4 penetrates the bottom of the heat sink 1, and a threaded hole is opened in the middle of the threaded connector 4. The top of the threaded connector 4 is bolted to the mounting base plate 5, and the limiting support sleeve 6 is fixedly connected to the top of the mounting base plate 5. The limiting support sleeve 6 is correspondingly set to the threaded connector 4, and the top end of the limiting support sleeve 6 is connected to the coil 2. The top is horizontally set, and a connecting threaded rod 7 is inserted in the middle of the limiting support sleeve 6. The connecting threaded rod 7 passes through the limiting support sleeve 6 and is connected to the inside of the threaded connection seat 4. A connecting nut 8 is fixedly connected to the top of the connecting threaded rod 7, and a mounting seat 9 is connected to the outer wall of the connecting threaded rod 7 by thread. The connecting nut 8 is located above the mounting seat 9. The setting of the connecting component 3 realizes the positioning connection between the heat sink 1 and the pressure plate 13. The setting of the connecting threaded rod 7 passes through the mounting seat 9 and connects to the inside of the threaded connection seat 4 to complete the connection between the pressure plate 13 and the heat sink 1. This facilitates the subsequent disassembly of the pressure plate 13 and the disassembly and maintenance of the coil 2, improving the ease of use of the device. The setting of the rubber protective pad 11 and the arc groove 12 protects the coil 2 and prevents the pressure plate 13 from being too forceful during positioning, which could damage the coil 2 and affect its service life.
[0023] Mounting base 9 is connected to pressure plate 13 by bolts. There are four mounting bases 9, which are symmetrically distributed in the middle of the four corners of pressure plate 13. A rubber protective pad 11 is connected to the bottom of pressure plate 13. The bottom of the rubber protective pad 11 has an arc-shaped groove 12, which is corresponding to the coil 2. One end of the arc-shaped groove 12 has a threaded groove 10. A connecting threaded rod 7 is inserted into the middle of the threaded groove 10. Heat sink 1 and coil 2 are connected together by adhesive. There are multiple ventilation grooves 14 in the middle of pressure plate 13, which are evenly distributed in the middle of pressure plate 13. The ventilation grooves 14 penetrate pressure plate 13. Ventilation grooves 14 are provided in the middle of both rubber protective pad 11 and pressure plate 13. The ventilation grooves 14 penetrate pressure plate 13 and rubber protective pad 11 to facilitate ventilation of coil 2 and reduce formaldehyde accumulation.
[0024] It should be noted that this utility model is an adhesive evaporator. In use, the heat dissipation plate 1 and the coil 2 are bonded together with adhesive. Then, the rubber protective pad 11 and the pressure plate 13 are placed on top of the coil 2 in sequence. The arc-shaped groove 12 at the bottom of the rubber protective pad 11 fits against the coil 2, thereby positioning and protecting the coil 2, preventing damage to the coil 2 due to friction during use, and extending the service life of the coil 2. Furthermore, one end of the pressure plate 13 is provided with a mounting base 9, and a threaded rod 7 passes through the mounting base 9 and the threaded groove. 10 is connected to the inside of the threaded connection seat 4.
