Description

Technical Field

[0001] The utility model relates to the technical field of air conditioner evaporators, in particular to an improved evaporator that is easy to maintain. Background Art

[0002] The air conditioner evaporator is one of the key components in the air conditioner refrigeration system. Its main function is to evaporate and absorb heat from the low-temperature and low-pressure liquid refrigerant, thereby reducing the temperature of the surrounding air. The evaporator usually consists of copper tubes and aluminum fins to increase the heat exchange area. When working, air flows through the evaporator, and heat is absorbed to achieve the refrigeration effect. Its performance directly affects the refrigeration efficiency and quality of the air conditioner; the evaporator needs to be maintained regularly to clean dirt and impurities to ensure good heat exchange performance. For example, an evaporator that has not been cleaned for a long time may reduce the refrigeration effect due to dust accumulation and increase energy consumption.

[0003] The prior art such as the utility model with the publication number CN218328753U discloses an air conditioner evaporator. This patent uses an evaporator main body, and the evaporator main body includes brackets. The number of the brackets is 2. A copper tube is bent and fixedly installed between the two brackets. Heat dissipation fins are fixedly installed between the two brackets at equal intervals. By driving the partition plate with a cross plate, the partition plate can be inserted between the heat dissipation fins, between the heat dissipation fins and the brackets, so as to support the heat dissipation fins, increase the protection of the heat dissipation fins, and prevent the heat dissipation fins from deforming during transportation. It is convenient to use. The protection mechanism can be quickly installed and disassembled through the clamping rod and the limiting plate. The operation is simple, and the protection mechanism can also be recycled and reused, which can save resources. The vertical plate increases the protection of the copper tube, the inlet and the outlet, and has high practicability. It solves the problem that the heat dissipation fins are made of aluminum alloy and are relatively thin. During the transportation of the air conditioner evaporator, the air conditioner evaporator will jolt or be squeezed, and the heat dissipation fins are easy to bend and deform, affecting its use.

[0004] During the maintenance process of the evaporator, there are existing air conditioner evaporators such as the above. Most of its heat dissipation fins are directly installed on the surface of the copper tube. When maintaining the evaporator later, since the heat dissipation fins are fixed on the copper tube, the disassembly becomes very difficult. This leads to interference from the heat dissipation fins during the maintenance operation by the staff, thus increasing the difficulty of maintenance. When it is necessary to replace the copper tube or perform in-depth cleaning on it, the difficult-to-dismantle heat dissipation fins will hinder the smooth progress of the operation, increase the time and energy required for maintenance, and affect the effect and quality of maintenance. Summary of the Utility Model

[0005] The object of the present utility model is to solve the drawbacks in the prior art that during deep cleaning, the difficult-to-dismantle heat dissipation fins will hinder the smooth progress of the operation, increase the time and effort required for maintenance, and affect the effect and quality of maintenance, and to propose an improved evaporator that is easy to maintain.

[0006] To achieve the above object, the present utility model adopts the following technical solution: An improved evaporator that is easy to maintain, including a first support plate, a second support plate, and an auxiliary component. The second support plate is arranged on the side surface of the first support plate. Copper tubes are fixedly connected to the surfaces of both the first support plate and the second support plate. An arc tube is installed on the side surface of the copper tube. The auxiliary component is arranged on the surfaces of the first support plate and the second support plate.

[0007] The auxiliary component includes a connection unit. The connection unit includes a limiting rod. Positioning holes are formed in the surfaces of both the first support plate and the second support plate. The limiting rod is inserted into the inner wall of the positioning hole. A binding plate is fixedly connected to the side surface of the limiting rod. A heat dissipation fin is sleeved on the surface of the limiting rod. Spacing limiting rings are fixedly connected to both sides of the heat dissipation fin. A U-shaped groove is formed in the surface of the heat dissipation fin. The heat dissipation fin is installed on the surface of the copper tube through the U-shaped groove.

[0008] The auxiliary component further includes a restraint unit. The restraint unit includes an assembly block. The assembly block is fixedly connected to the side surface of the second support plate. A receiving cavity is formed in the surface of the assembly block. An anti-slip rotating shaft is rotatably connected to the inner wall of the receiving cavity where the assembly block is located. Threaded rods are fixedly connected to both ends of the anti-slip rotating shaft. A jacking sleeve is threadedly connected to the surface of the threaded rod. The jacking sleeve is slidably connected to the inner wall of the receiving cavity. A latch is fixedly connected to the end face of the jacking sleeve. A U-shaped frame is fixedly connected to the side surface of the second support plate. The limiting rod is inserted into the inner wall of the U-shaped frame. A locking hole is formed in the surface of the limiting rod. The latch is inserted into the inner wall of the locking hole.

[0009] Preferably, a protrusion is fixedly connected to the outer circumference of the jacking sleeve. A sliding groove is formed in the inner wall of the receiving cavity where the assembly block is located. The protrusion is slidably connected to the inner wall of the sliding groove. Through the protrusion on the outer circumference of the jacking sleeve, the moving direction of the jacking sleeve can be guided in cooperation with the sliding groove to ensure that when the jacking sleeve meshes with the threaded shaft, it can be driven by the threaded shaft to move in the vertical direction.

[0010] Preferably, the number of the limiting rods is four. The four limiting rods are arranged diagonally with respect to the first support plate. The spacing limiting rings are sleeved on the surface of the limiting rods. By means of the limiting rods installed in the positioning holes, the position of the heat dissipation fins can be restricted on the surface of the copper tube, thereby ensuring stable contact between the heat dissipation fins and the copper tube.

[0011] Preferably, there are two sets of the heat sinks, and the two sets of heat sinks are symmetrically arranged front and back. The number of the heat sinks in the two sets is multiple, and the multiple heat sinks are horizontally distributed and arranged with respect to the copper tube. By designing the heat sinks into two sets and installing them on both sides of the device respectively, it is convenient for the staff to disassemble the heat sinks.

[0012] Preferably, the number of the assembly blocks is four, and the four assembly blocks are diagonally arranged with respect to the second support plate. The position of the anti-slip rotating shaft can be restricted through the assembly blocks to ensure the stability of the anti-slip rotating shaft, and the rotation axis of the anti-slip rotating shaft can be defined.

[0013] Preferably, the lifting sleeve is slidably connected to the inner wall of the receiving cavity. Through the lifting sleeve installed on the threaded rod, while the staff operates the threaded rod to rotate, the position of the pin can be adjusted in cooperation with the threaded rod.

[0014] Preferably, the pin is slidably connected to the inner wall of the receiving cavity, and the pin is inserted into the inner wall of the U-shaped frame. By restricting the pin in the card hole and the U-shaped frame, the position of the limiting rod can be defined in the restricted state.

[0015] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0016] In the present utility model, when maintaining the evaporator by setting the auxiliary component, the anti-slip rotating shaft is rotated counterclockwise. The anti-slip rotating shaft drives the threaded rod, and the threaded rod meshes with the lifting sleeve under the action of the anti-slip rotating shaft. The lifting sleeve, under the guidance of the convex portion and the sliding groove, pulls the pin out of the U-shaped frame and the card hole. When the pin completely slides into the interior of the receiving cavity, the binding plate is pulled outwards. The binding plate pulls the limiting rod under force, and the limiting rod is displaced under force and gradually disengages from the heat sink. When the heat sink loses the restraint of the limiting rod, the heat sink can be removed from the copper tube, thereby exposing the copper tube to facilitate deep cleaning of the copper tube. At the same time, through the above operations, it is convenient for the staff to replace the damaged heat sink. By setting the auxiliary component, the heat dissipation fins of the device can be quickly disassembled, thereby reducing the problem that the fixed installation of the heat dissipation fins of the device on the copper tube increases the difficulty of the maintenance operation of the device, and further improving the convenience of device maintenance.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: an improved evaporator that is easy to maintain, including a first support plate 1, a second support plate 2 and an auxiliary component 5. The second support plate 2 is arranged on the side surface of the first support plate 1. The surfaces of the first support plate 1 and the second support plate 2 are both fixedly connected with copper tubes 3. An arc tube 4 is installed on the side surface of the copper tube 3. The auxiliary component 5 is arranged on the surfaces of the first support plate 1 and the second support plate 2.

[0025] In this implementation scheme: the auxiliary component 5 includes a connection unit 51. The connection unit 51 includes a limiting rod 512. Positioning holes 511 are opened on the surfaces of the first support plate 1 and the second support plate 2. The limiting rod 512 is inserted into the inner wall of the positioning hole 511. A binding plate 513 is fixedly connected to the side surface of the limiting rod 512. A heat sink 514 is sleeved on the surface of the limiting rod 512. Spacing limiting rings 515 are fixedly connected to both sides of the heat sink 514. A U-shaped groove 516 is opened on the surface of the heat sink 514. The heat sink 514 is installed on the surface of the copper tube 3 through the U-shaped groove 516;

[0026] The auxiliary component 5 further includes a constraint unit 52. The constraint unit 52 includes an assembly block 521. The assembly block 521 is fixedly connected to the side surface of the second support plate 2. A storage cavity is formed on the surface of the assembly block 521. An anti-slip rotating shaft 522 is rotatably connected to the inner wall of the assembly block 521 at the storage cavity. Both ends of the anti-slip rotating shaft 522 are fixedly connected with threaded rods 523. A jacking sleeve 524 is threadedly connected to the surface of the threaded rod 523. The jacking sleeve 524 is slidably connected to the inner wall of the storage cavity. A retaining pin 525 is fixedly connected to the end face of the jacking sleeve 524. A U-shaped frame 526 is fixedly connected to the side surface of the second support plate 2. The limiting rod 512 is inserted into the inner wall of the U-shaped frame 526. A locking hole is formed on the surface of the limiting rod 512. The retaining pin 525 is inserted into the inner wall of the locking hole.

[0027] Specifically, a convex portion is fixedly connected to the outer circumference of the jacking sleeve 524. A sliding groove 527 is formed on the inner wall of the assembly block 521 at the storage cavity. The convex portion is slidably connected to the inner wall of the sliding groove 527. Through the convex portion on the outer circumference of the jacking sleeve 524, the moving direction of the jacking sleeve 524 can be guided in cooperation with the sliding groove 527, so as to ensure that when the jacking sleeve 524 meshes with the threaded shaft, it can be driven by the threaded shaft to move in the vertical direction.

[0028] Specifically, the number of the limiting rods 512 is four. The four limiting rods 512 are diagonally arranged with respect to the first support plate 1. The spacing limiting ring 515 is sleeved on the surface of the limiting rod 512.

[0029] In this embodiment: Through the limiting rod 512 installed in the positioning hole 511, the position of the heat sink 514 can be limited on the surface of the copper tube 3, so as to ensure stable contact between the heat sink 514 and the copper tube 3.

[0030] Specifically, there are two groups of heat sinks 514. The two groups of heat sinks 514 are symmetrically arranged front and back. The number of the multiple heat sinks 514 in the two groups is multiple. The multiple heat sinks 514 are horizontally distributed and arranged with respect to the copper tube 3. By designing the heat sink 514 into two groups and installing them on both sides of the device respectively, it is convenient for the staff to disassemble the heat sink 514.

[0031] In this embodiment: The number of the assembly blocks 521 is four. The four assembly blocks 521 are diagonally arranged with respect to the second support plate 2.

[0032] In this embodiment: The position of the anti-slip rotating shaft 522 can be limited through the assembly block 521 to ensure the stability of the anti-slip rotating shaft 522, and the rotation axis of the anti-slip rotating shaft 522 can be defined.

[0033] Specifically, the lifting sleeve 524 is slidably connected to the inner wall of the receiving cavity. By means of the lifting sleeve 524 mounted on the threaded rod 523, the position of the pin 525 can be adjusted in cooperation with the threaded rod 523 while the staff operates the rotation of the threaded rod 523.

[0034] Specifically, the pin 525 is slidably connected to the inner wall of the receiving cavity, and the pin 525 is inserted into the inner wall of the U-shaped frame 526.

[0035] In this embodiment: By restricting the pin 525 within the card hole and the U-shaped frame 526, the position of the limit rod 512 can be defined in the restricted state.

[0036] Working principle: When maintaining the evaporator, turn the anti-slip rotating shaft 522 counterclockwise. The anti-slip rotating shaft 522 drives the threaded rod 523. Under the action of the anti-slip rotating shaft 522, the threaded rod 523 meshes with the lifting sleeve 524. The lifting sleeve 524, under the guidance of the convex portion and the sliding groove 527, pulls the pin 525 out of the U-shaped frame 526 and the card hole. When the pin 525 completely slides into the interior of the receiving cavity, pull the binding plate 513 outwards. The binding plate 513 pulls the limit rod 512 under force, and the limit rod 512 displaces under force and gradually disengages from the heat sink 514. When the heat sink 514 loses the restraint of the limit rod 512, the heat sink 514 can be removed from the copper tube 3, thereby exposing the copper tube 3 to facilitate deep cleaning of the copper tube 3. At the same time, through the above operations, it is convenient for the staff to replace the damaged heat sink 514.
