Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically to a tube-plate bonded evaporator. Background Technology

[0002] Direct-cooling refrigerators typically use adhesive evaporators, where the evaporator coils are bonded to the heat dissipation plate using hot melt adhesive. The heat dissipation plate is then bonded to the refrigerator liner, and the space between the refrigerator liner and the refrigerator panel is filled with foam.

[0003] Since the coil is bonded to the surface of the heat sink, during transportation or installation, factors such as bumps and knocks can cause the coil to shake and rub against the heat sink, resulting in the coating on the coil peeling off. This affects the normal use of the coil and its heat conduction effect. The bolt connection method is not convenient for quick disassembly and assembly. Therefore, this application proposes a tube-plate bonded evaporator. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] This utility model provides a tube-plate bonded evaporator. When the left side of the cover plate of the fixing component is connected to the slot, the right side of the cover plate engages with a single locking tooth, achieving a quick-locking connection. This facilitates rapid assembly and disassembly. Furthermore, after bolt installation, the bolts are held in place by the locking teeth, preventing the teeth from springing open and causing loosening, thus improving connection stability. Please refer to [link / reference]. Figures 1-4 It includes: heat sink 100, heat conduction coil 200, fixing component 300 and connecting bolt 400.

[0031] The heat sink 100 includes a heat-conducting plate 110, a heat-conducting groove 120, a slot 130, a tooth 140, and a connecting hole 150. The heat-conducting plate 110 has a heat-conducting groove 120, a slot 130 on the left side of the heat-conducting plate 110, a tooth 140 on the right side of the heat-conducting plate 110, and a connecting hole 150 on the outer side of the heat-conducting plate 110.

[0032] Among them, the slot 130 is a rectangular long slot, the tooth 140 is an elastic tooth, and the connecting hole 150 is evenly distributed on both sides of the heat-conducting plate 110. The connecting hole 150 is a screw hole.

[0033] The heat-conducting coil 200 is installed on the heat-conducting groove 120, and the medium flows through the heat-conducting coil 200.

[0034] The fixing component 300 is disposed on the heat conduction coil 200. The fixing component 300 includes a cover plate 310 and a hook 320. The left end of the cover plate 310 is provided with a hook 320 that connects to the slot 130.

[0035] The bottom of the cover plate 310 is provided with a connecting groove that fits into the heat-conducting coil 200. Both the heat-conducting groove 120 and the connecting groove are curved grooves. The hook 320 is formed by bending the cover plate 310. The cover plate 310 is locked in the slot 130 by the hook 320. When the left side of the cover plate 310 is connected to the slot 130, the right side of the cover plate 310 is engaged with the tooth 140.

[0036] The connecting bolt 400 is connected to the connecting hole 150. The connecting bolt 400 is an internal hex bolt. When the connecting bolt 400 is connected, it is held by the side of the retaining tooth 140.

[0037] Because heat conduction and heat dissipation are required, thermal grease is applied to the connection points between the heat conduction coil 200 and the heat conduction groove 120, and between the heat conduction coil 200 and the cover plate 310, to improve the heat conduction effect.

[0038] In practical use, the cover plate 310 is secured in the slot 130 by the hook 320. With the left side of the cover plate 310 connected to the slot 130, the right side of the cover plate 310 is engaged with the tooth 140 to complete the insertion connection. After connection, the connecting bolt 400 holds the side of the tooth 140 to prevent the elastic tooth 140 from bending and causing the cover plate 310 to loosen, thus improving connection stability. It also effectively transfers heat through thermal grease, improving the heat conduction effect.

[0039] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
