Description

Technical Field

[0001] This utility model belongs to the field of evaporator technology, specifically relating to a refrigerator finned evaporator. Background Technology

[0002] Among the frost-free air-cooled refrigerators commonly found on the market today, finned evaporators are the most widely used. The effective heat exchange area, heat exchange efficiency, and reliability of the evaporator have become the most critical performance indicators for evaluating refrigerator performance.

[0003] Chinese patent CN213040794U discloses a refrigerator evaporator fin, including mounting fins. The mounting fins have internal mounting grooves, and a connecting block is movably engaged within the mounting grooves. A fixing hole is located at the center of the connecting block. The beneficial effects of this invention are: the refrigerator evaporator fins, through friction fixing plates, allow the mounting fins and movable fins to be securely mounted on the outer wall of a copper tube, preventing wobbling. Because the mounting fins and movable fins are detachable, expanding the copper tube is unnecessary during installation and production, avoiding damage to the evaporator caused by tube expansion and reducing the probability of evaporator damage. This brings many conveniences to the production and use of the evaporator, effectively improving the practicality and stability of the refrigerator evaporator fins.

[0004] However, there are still some shortcomings. For example, existing evaporators simply use heat exchange coils and fins for heat exchange, resulting in a simple heat exchange structure that cannot fully transfer heat and reduces the heat exchange efficiency of the evaporator. Utility Model Content

[0005] The purpose of this invention is to provide a refrigerator finned evaporator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a refrigerator finned evaporator, comprising heat exchange fins, a heat exchange coil fixedly connected inside the heat exchange fins, and multiple heat-conducting components disposed inside the heat exchange coil. Each heat-conducting component includes a first heat-conducting plate and a second heat-conducting plate fixedly connected to the inner wall of the heat exchange coil. The second heat-conducting plate is located on the opposite side of the first heat-conducting plate. A first flow guide hole is opened inside the first heat-conducting plate, and a second flow guide hole is opened inside the second heat-conducting plate. A heat-conducting column is fixedly connected between the first heat-conducting plate and the second heat-conducting plate, and a heat-conducting sheet is fixedly connected to the outer wall of the heat-conducting column.

[0007] As a further embodiment of this utility model: there are multiple first guide holes and multiple second guide holes, and the first guide holes and the second guide holes are interconnected.

[0008] As a further embodiment of this utility model: the number of heat-conducting pillars and heat-conducting sheets are both multiple, the shape of the heat-conducting pillars is cylindrical, and the shape of the heat-conducting sheets is rectangular.

[0009] As a further embodiment of this utility model: the number of heat exchange fins is multiple, one end of the heat exchange coil is fixedly connected to an output pipe, and the other end of the heat exchange coil is fixedly connected to an input pipe.

[0010] As a further improvement of this utility model: the heat exchange fins are provided with heat dissipation grooves, a first heat dissipation hole and a second heat dissipation hole inside, and the first heat dissipation hole and the second heat dissipation hole are both connected to the heat dissipation grooves.

[0011] As a further improvement of this utility model: the number of heat dissipation grooves, the first heat dissipation hole and the second heat dissipation hole are all multiple, and the heat dissipation grooves, the first heat dissipation hole and the second heat dissipation hole form an integral heat exchange channel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The refrigerator's finned evaporator, through its designed heat-conducting components, can effectively improve the heat conduction of the heat exchange coils in the evaporator, allowing the heat exchange coils to transfer heat to the liquid refrigerant more fully, thus enabling the liquid refrigerant to better displace heat.

[0014] The refrigerator finned evaporator, through the design of heat dissipation grooves, first heat dissipation holes, and second heat dissipation holes, can effectively improve the heat exchange effect of the heat exchange fins. The heat dissipation grooves, first heat dissipation holes, and second heat dissipation holes form an integrated heat exchange channel, allowing air to be exhausted between the gaps formed by different heat exchange fins, increasing the contact area with air, and improving the heat dissipation efficiency of the heat exchange fins.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-4 This utility model provides a refrigerator finned evaporator, including heat exchange fins 1, a heat exchange coil 2 fixedly connected inside the heat exchange fins 1, a plurality of heat conduction components 3 arranged inside the heat exchange coil 2, the number of heat exchange fins 1 is multiple, an output pipe is fixedly connected to one end of the heat exchange coil 2, and an input pipe is fixedly connected to the other end of the heat exchange coil 2.

[0023] like Figure 2 and Figure 3 As shown, the heat-conducting assembly 3 includes a first heat-conducting plate 4 and a second heat-conducting plate 5 fixedly connected to the inner wall of the heat exchange coil 2. The second heat-conducting plate 5 is located on the opposite side of the first heat-conducting plate 4. A first guide hole 6 is opened inside the first heat-conducting plate 4, and a second guide hole 7 is opened inside the second heat-conducting plate 5. A heat-conducting column 8 is fixedly connected between the first heat-conducting plate 4 and the second heat-conducting plate 5. A heat-conducting sheet 9 is fixedly connected to the outer wall of the heat-conducting column 8. There are multiple first guide holes 6 and multiple second guide holes 7. The first guide holes 6 and multiple second guide holes 7 are interconnected. There are multiple heat-conducting columns 8 and multiple heat-conducting sheets 9. The heat-conducting column 8 is cylindrical in shape, and the heat-conducting sheet 9 is rectangular in shape.

[0024] like Figure 1 and Figure 4 As shown, the heat exchange fin 1 has a heat dissipation groove 10, a first heat dissipation hole 11 and a second heat dissipation hole 12 inside. The first heat dissipation hole 11 and the second heat dissipation hole 12 are both connected to the heat dissipation groove 10. There are multiple heat dissipation grooves 10, first heat dissipation holes 11 and second heat dissipation holes 12. The heat dissipation grooves 10, first heat dissipation holes 11 and second heat dissipation holes 12 form an integral heat exchange channel.

[0025] Specifically, when the heat exchange fins 1 dissipate heat, the heat is discharged through the heat dissipation groove 10, the first heat dissipation hole 11 and the second heat dissipation hole 12. The heat dissipation groove 10, the first heat dissipation hole 11 and the second heat dissipation hole 12 form an integral heat exchange channel, allowing air to be discharged between the gaps formed by different heat exchange fins 1, increasing the contact area with air and improving the heat dissipation efficiency of the heat exchange fins 1.

[0026] The working principle of this utility model:

[0027] In use, the heat exchange coil 2 discharges or discharges liquid refrigerant through its output and input ends, allowing the liquid refrigerant to absorb heat in the heat exchange coil 2. The liquid refrigerant then contacts the first heat-conducting plate 4 and the second heat-conducting plate 5. Flow is achieved through the first guide hole 6 inside the first heat-conducting plate 4 and the second guide hole 7 inside the second heat-conducting plate 5. During this flow, the refrigerant again contacts the heat-conducting column 8 and the heat-conducting plate 9. The first heat-conducting plate 4, the second heat-conducting plate 5, the heat-conducting column 8, and the heat-conducting plate 9 are all made of thermally conductive metal materials, resulting in good thermal conductivity. This increases the contact area between the heat exchange coil 2 and the liquid refrigerant, improving the heat exchange effect of the heat exchange coil 2 and the heat exchange efficiency of the evaporator.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
