Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to an inclined plug - type evaporator fin and an evaporator. Background Art

[0002] Evaporator fins are devices used to increase the heat exchange surface area, usually used in the evaporator part of refrigeration or air - conditioning systems. They are usually composed of a series of thin sheets or fins, which are located on pipes or tubes to increase the heat exchange with the surrounding air. When a cooling medium (such as refrigerant or water) flows through the pipes, the fins transfer heat to the surrounding air, thereby cooling or evaporating the cooling medium to achieve the refrigeration effect.

[0003] The traditional design of evaporator fins is limited by the contact area with air, resulting in limited heat exchange efficiency. The space between adjacent fins is difficult to quickly make new contact with the flowing air, which affects the refrigeration effect of the entire system.

[0004] Therefore, we propose an inclined plug - type evaporator fin and an evaporator. Summary of the Utility Model

[0005] The main object of the utility model is to solve the technical problems existing in the above - mentioned prior art, and provide an inclined plug - type evaporator fin and an evaporator.

[0006] To achieve the above object, the utility model adopts the following technical scheme. An inclined plug - type evaporator fin includes two sets of parallel fixed plates arranged up and down. Between the two sets of fixed plates, multiple sets of fins are vertically arranged and are movably connected to the two sets of fixed plates. A vertical space is formed between adjacent two sets of fins. Ventilation slots corresponding to the end parts of the fins and the space between adjacent two sets of fins are vertically opened on both sets of fixed plates. A cleaning component for cleaning the surface of the fins is arranged at the bottom of multiple sets of fins.

[0007] Preferably, at the positions corresponding to the fins between the two sets of fixed plates, a number of connecting rods equal to the number of fins are vertically connected. The connecting rods are cylindrical metal long rods. An arc - shaped connecting sleeve is connected to the rear side of the fins. The fins are movably connected to the connecting rods through the connecting sleeves so that the fins can slightly swing and adjust the angle between the two sets of fixed plates. The rear side of the connecting rods is in fluid contact with the evaporator through a heat - conducting back plate.

[0008] Preferably, ventilation slot holes penetrating the fins up and down are opened inside the fins.

[0009] Preferably, multiple sets of auxiliary fins connected to the inner wall of the fins are arranged inside the ventilation slot holes.

[0010] Preferably, the cleaning component includes a cross bar, a sponge block, a clamping cavity, a ventilation cavity and a handle. The cross bar is a rectangular long bar arranged horizontally. The sponge block is installed inside the cross bar. A clamping cavity with the same shape as the outer surface of the fin and a ventilation cavity corresponding to the space between two adjacent groups of fins are formed on the sponge block. The handle is fixedly connected to the outer wall surface of the cross bar.

[0011] An evaporator includes the fins described above.

[0012] Beneficial effects

[0013] The utility model provides an inclined plug - type evaporator fin and an evaporator, which have the following beneficial effects:

[0014] (1) For the inclined plug - type evaporator fin and the evaporator, the outside cold air moves horizontally from the outside of the fin to take away the heat on the fin. Since the air is flowing on the outside of the fin, the pressure generated by the wind speed on the outside of the fin will cause the air in the space between two adjacent groups of fins to move outward. The cold air at the upper and lower ends will refill the space between two adjacent groups of fins through the ventilation slots, and so on in a cycle, improving the contact efficiency between the fin and the cold air and increasing the temperature conduction speed.

[0015] (2) For the inclined plug - type evaporator fin and the evaporator, the cleaning component can clean the outside of the fin. By slightly squeezing inward and moving the handle upward, the handle drives the cross bar and the sponge block to move to wipe the outer surface of the fin to remove dust. By setting the clamping cavity, the maximum - area contact with the outside of the fin can be realized, improving the cleaning efficiency. By setting the ventilation cavity, the air flow between two adjacent groups of fins can be prevented from being interfered. Description of the drawings

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1: An obliquely inserted evaporator fin, as Figure 1 shown, including two sets of parallel fixed plates 1 arranged up and down. Between the two sets of fixed plates 1 up and down, multiple groups of fins 2 vertically arranged and movably connected to the two sets of fixed plates 1 are provided. A vertical space is formed between adjacent two groups of fins 2. Ventilation grooves 3 corresponding to the end parts of the fins 2 and the space positions between adjacent two groups of fins 2 are vertically opened on both sets of fixed plates 1. A cleaning component 4 for cleaning the surface of the fins 2 is provided at the bottom of multiple groups of fins 2.

[0027] During use, the entire fin 2 assembly is installed on the evaporator. The fins 2 are in contact with the outside to achieve heat conduction. The cold air outside moves horizontally from the outside of the fins 2 to take away the heat on the fins 2. Since the air is flowing on the outside of the fins 2, the pressure generated by the wind speed on the outside of the fins 2 will cause the air in the space between adjacent two groups of fins 2 to move outward. The cold air at the upper and lower ends will refill the space between adjacent two groups of fins 2 through the ventilation grooves 3, and circulate in this way to improve the contact efficiency between the fins 2 and the cold air and increase the temperature conduction speed.

[0028] Embodiment 2: On the basis of the above embodiment, asFigure 3 As shown in the figure, the cleaning component 4 includes a cross bar 41, a sponge block 42, a clamping cavity 43, a ventilation cavity 44 and a handle 45. The cross bar 41 is a rectangular long bar arranged horizontally. The sponge block 42 is installed inside the cross bar 41. A clamping cavity 43 with the same shape as the outer surface of the fin 2 and a ventilation cavity 44 corresponding to the space between two adjacent groups of fins 2 are formed on the sponge block 42. The handle 45 is fixedly connected to the outer wall surface of the cross bar 41.

[0029] By setting the cleaning component 4, the outside of the fin 2 can be cleaned. By slightly squeezing inward and moving the handle 45 upward, the handle 45 drives the cross bar 41 and the sponge block 42 to move to wipe the outer surface of the fin 2 to remove dust. By setting the clamping cavity 43, the maximum area contact with the outside of the fin 2 can be achieved, improving the cleaning efficiency. The ventilation cavity 44 is set to prevent interference with the air flow in the space between two adjacent groups of fins 2.

[0030] Embodiment 3: On the basis of Embodiment 1, as Figure 2 shown, a number of connecting rods 6 equal to the number of fins 2 are vertically connected at the positions corresponding to the fins 2 between the two fixing plates 1. The connecting rods 6 are cylindrical metal long rods. An arc-shaped connecting sleeve 5 is connected to the rear side of the fin 2. The fin 2 is movably connected to the connecting rod 6 through the connecting sleeve 5 so that the fin 2 can slightly swing between the two fixing plates 1 to adjust the angle. The rear side of the connecting rod 6 is in fluid contact with the evaporator through a heat-conducting back plate 7.

[0031] By adjusting the angle of the fin 2, the direction and speed of air flow can be better controlled, optimizing the heat exchange process. The adjustable angle design also enables the evaporator to cope with different installation scenarios and space limitations, improving the flexibility and convenience of installation.

[0032] Embodiment 4: On the basis of the above embodiments, as Figure 4 and Figure 5 shown, ventilation slots 8 penetrating the fin 2 up and down are formed inside the fin 2.

[0033] By setting the ventilation slots 8, the effective surface area of the fin 2 is increased, thereby increasing the contact area with the surrounding air and enhancing the heat transfer efficiency. By forming ventilation slots 8 on the fin 2, the material consumption can be reduced while maintaining the structural strength, improving the material utilization rate and reducing the overall weight of the fin 2.

[0034] A number of auxiliary fins 9 connected to the inner wall of the fin 2 are arranged inside the ventilation slots 8.

[0035] By setting the auxiliary fins 9, the surface area of the fins 2 can be significantly increased, and the contact area between the air and the surface of the fins 2 can be increased. The ventilation slots 8 penetrating the fins 2 can guide the air to flow along the inner wall surface of the fins 2, and through the design of the auxiliary fins 9, more turbulence of the air can be generated on the inner wall surface of the fins 2, which helps to optimize the air flow and improve the heat transfer efficiency. By setting the auxiliary fins 9, the structure of the hollow fins 2 can also be made more robust, enabling it to better withstand pressure and vibration, and improving durability and reliability.
