Description

Technical Field

[0001] This invention belongs to the field of energy-saving evaporator technology, specifically a pull-out desert environment air conditioning evaporator. Background Technology

[0002] Construction machinery operating in desert environments often suffers from severe air conditioning clogging due to high dust levels and sandstorms. This is especially true for the evaporator, where condensation forms on its surface during cooling. This condensation mixes and clumps with the sand, clogging the evaporator fins, reducing airflow, or even stopping altogether. In severe cases, prolonged high back pressure can damage the evaporator motor, ultimately causing complete air conditioning failure. In the scorching desert, this air conditioning malfunction makes it impossible for operators to work in the hot cab, leading to equipment downtime and significant economic losses.

[0003] Existing desert evaporators are all designed as a single unit because the whole unit can ensure the evaporator's sealing performance. However, the existing evaporators are connected to various pipes, air ducts, and wires, without an integrated design. When the evaporator becomes dirty and clogged, all pipes and lines need to be removed, the air conditioning unit needs to be disassembled, and the evaporator core needs to be removed and cleaned. This process requires professional personnel to open the pipes and release the refrigerant.

[0004] Because the desert is far from air conditioning repair shops in towns, operators cannot disassemble and clean the complex air conditioning evaporators. They can only ask professionals to come to their homes long distances for repairs or tow the entire unit to an air conditioning repair shop in town. The whole process will result in high repair costs and energy consumption, and the equipment will be out of service. This will not only affect the comfort of the equipment operators, but also cause huge economic losses.

[0005] Therefore, the present invention provides a pull-out desert environment air conditioning evaporator. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a pull-out desert environment air conditioning evaporator, comprising an evaporator core integrated module, an evaporator main shell, and a pull-out guide mechanism disposed within the evaporator body; the evaporator core integrated module is pull-out mounted on the evaporator main shell, and the pull-out guide mechanism enables it to move in a predetermined direction, so that during maintenance, the evaporator core integrated module can be pulled out from the evaporator main shell to an external position for cleaning or replacement without disassembling the air conditioning unit or releasing the refrigerant.

[0008] Preferably, the pull-out guide mechanism includes at least one set of pull-out guide rails, which are concave-convex mating structures and symmetrically arranged on both sides of the evaporator core integrated module to guide smooth pull-out.

[0009] Preferably, the pull-out guide mechanism further includes a limiting steel wire rope and steel wire rope anchor points. Several steel wire rope anchor points are respectively fixed to the evaporator core integrated module and the evaporator main shell. The limiting steel wire rope connects the evaporator core integrated module and the evaporator main shell and is used to limit the pull-out limit position.

[0010] Preferably, it also includes a quick-release hand-tightening buckle, which is used for quick sealing connection and separation. The evaporator core integrated module is connected to the evaporator main shell through the quick-release hand-tightening buckle.

[0011] Preferably, the quick-release hand-tightening buckle includes a spring plate, a dovetail fin, and a handle. The handle is fixed to the bottom of the dovetail fin, the spring plate is sleeved between the dovetail fin and the handle, the main housing of the evaporator has a misalignment hole, and a locking strip is fixed to the main housing of the evaporator corresponding to the misalignment hole. The quick-release hand-tightening buckle passes through the misalignment hole via the dovetail fin and can be locked or released by rotating 90°.

[0012] Preferably, the evaporator core integrated module includes an evaporator core, a flexible piping assembly, and a mounting frame. The flexible piping assembly includes an evaporator liquid hose assembly and an evaporator gas hose assembly, arranged in a curved path to allow the piping to change freely when pulled out. The flexible piping assembly and the evaporator core are integrated on the mounting frame to form a movable unit, and the quick-release hand-tightening buckle is rotatably connected to the edge of the mounting frame.

[0013] Preferably, the swallowtail fin has symmetrically arranged notches on one side relative to the locking strip. When the swallowtail fin passes through the misalignment hole, it is rotated 90° to lock the swallowtail fin into the locking strip for circumferential rotational limiting.

[0014] Preferably, a waterproof sealing ring is also included, which is set at the flange mating surface between the evaporator core integrated module and the evaporator main shell to prevent condensate from overflowing and sand and dust from entering.

[0015] Preferably, the evaporator body is provided with an evaporator access cover for accessing the evaporator core integrated module, and the evaporator access cover can be opened to expose the pull-out path.

[0016] Preferably, the evaporator core integrated module further includes a condensate drainage system, which includes a water collection box, a first drain hose, a second drain hose, and a drain tee for collecting and draining condensate, and is integrated with the refrigeration system in the same module.

[0017] The beneficial effects of this invention are as follows: 1. The present invention discloses a pull-out desert environment air conditioning evaporator, which, by setting a pull-out guide mechanism, allows the evaporator core integrated module to be smoothly pulled out of the evaporator body as a whole along the guide rail. This facilitates maintenance personnel to quickly clean or replace the filter element and fin assembly on-site, effectively reducing maintenance difficulty and downtime. At the same time, the sealed structure design ensures that refrigerant leakage will not occur due to vibration during normal use, making the maintenance of the evaporator core integrated module more convenient, the maintenance cycle shorter, and more energy-efficient.

[0018] 2. The present invention discloses a pull-out desert environment air conditioning evaporator. A quick-release hand-tightening buckle on the evaporator core integrated module passes through the side of the evaporator main housing. Rotation locks the quick-release hand-tightening buckle between the evaporator core integrated module and the evaporator main housing, thus completing the connection. When the evaporator core integrated module needs to be pulled out, the quick-release hand-tightening buckle is removed by rotating in the opposite direction, freeing the evaporator core integrated module from its confinement. This allows the evaporator core integrated module to be removed from the evaporator main housing, further improving maintenance efficiency. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 7 As shown in the embodiment of the present invention, a pull-out desert environment air conditioning evaporator includes an evaporator core 14 integrated module, an evaporator main shell, and a pull-out guide mechanism disposed within the evaporator body 19. The evaporator core 14 integrated module is pull-out mounted on the evaporator main shell and is pulled out along a predetermined direction by the pull-out guide mechanism. This allows the evaporator core 14 integrated module to be pulled out from the evaporator main shell to an external position for cleaning or replacement during maintenance, without disassembling the air conditioning unit or releasing the refrigerant.

[0024] In the existing technology, especially in the harsh desert environment, the evaporator core 14 in the air conditioning evaporator of the engineering vehicle is prone to blockage and corrosion due to long-term exposure to the wind and sand environment, resulting in a decrease in heat exchange efficiency and a shortened maintenance cycle.

[0025] In one embodiment of the present invention, by setting a pull-out guide mechanism, the evaporator core 14 integrated module can be smoothly pulled out of the evaporator body 19, specifically from the evaporator main shell, along the guide rail. This facilitates quick cleaning or replacement of the filter element and fin assembly by maintenance personnel on-site, effectively reducing maintenance difficulty and downtime. At the same time, the sealed structure design ensures that refrigerant leakage will not occur due to vibration during normal use. Specifically, when the evaporator of the engineering vehicle air conditioner becomes clogged due to long-term exposure to wind and sand, causing a decrease in heat exchange efficiency, maintenance personnel can manually pull out the evaporator core 14 integrated module, causing it to be pulled out of the evaporator main shell along the predetermined sliding direction of the pull-out guide mechanism. After the evaporator core 14 integrated module is removed from the evaporator main shell, it is exposed to the outside, allowing for direct cleaning or replacement of the evaporator core 14 integrated module without disassembling the evaporator and its supporting pipelines. This makes the maintenance of the evaporator core 14 integrated module more convenient, shortens the maintenance cycle, and is more energy-efficient.

[0026] like Figures 1 to 4 As shown, the pull-out guide mechanism includes at least one set of pull-out guide rails 4. The pull-out guide rails 4 have a concave-convex fit structure and are symmetrically arranged on both sides of the evaporator core 14 integrated module to guide smooth pull-out.

[0027] As described above, in this embodiment, the evaporator core 14 integrated module is connected to the evaporator main housing via a pull-out guide rail 4. Based on the pull-out guide rail 4, when maintenance of the evaporator core 14 integrated module is required, the evaporator core 14 integrated module can be smoothly pulled out from the evaporator main housing and exposed to the external space based on the symmetrically arranged pull-out guide rail 4, thereby facilitating maintenance personnel to clean or replace the evaporator core 14 integrated module.

[0028] like Figures 1 to 4 As shown, the pull-out guide mechanism also includes a limiting steel wire rope 5 and a steel wire rope anchor point 6. Several steel wire rope anchor points 6 are respectively fixed to the evaporator core 14 integrated module and the evaporator main shell. The limiting steel wire rope 5 connects the evaporator core 14 integrated module and the evaporator main shell and is used to limit the pull-out limit position.

[0029] When the evaporator core 14 integrated module is pulled out of the evaporator main housing, although the pull-out guide rail 4 guides the evaporator core 14 integrated module to ensure its smooth removal, the evaporator core 14 integrated module has a certain weight. If it is not limited or blocked, it will slide directly out of the evaporator main housing. In addition to guiding the evaporator core 14 integrated module based on the pull-out guide rail 4, a limiting steel wire rope 5 and steel wire rope anchor points 6 are also provided. Specifically, in this embodiment, multiple steel wire rope anchor points 6 are arranged and fixed to the side walls of the evaporator core 14 integrated module and the evaporator main housing, and the two ends of the limiting steel wire rope 5 are respectively connected to On the two parallel steel wire rope anchor points 6, the pull-out limit position of the evaporator core 14 integrated module is limited. It is foreseeable that when the evaporator core 14 integrated module is retracted into the evaporator main shell, the limiting steel wire rope 5 bends and retracts into the evaporator body 19. When the evaporator core 14 integrated module needs to be cleaned or replaced, the evaporator core 14 integrated module is pulled out of the evaporator main shell. The displacement path of the evaporator core 14 integrated module is guided by the pull-out guide rail 4, so that the evaporator core 14 integrated module slides out smoothly. In addition, the limiting steel wire rope 5 can limit the evaporator core 14 integrated module, so that the evaporator core 14 integrated module stops after sliding to the limit position, thereby avoiding the evaporator core 14 integrated module from slipping and causing damage.

[0030] like Figure 1 , Figures 7 to 10As shown, it also includes a quick-release hand-tightening buckle 9, which is used for quick sealing connection and separation. The evaporator core 14 integrated module is connected to the evaporator main shell through the quick-release hand-tightening buckle 9.

[0031] Because the evaporator core 14 is prone to clogging in desert environments and requires regular maintenance, cleaning, or replacement, to improve the separation efficiency of the evaporator core 14 integrated module from the evaporator main housing in the above embodiments, in this embodiment, the connection between the evaporator core 14 integrated module and the evaporator main housing is completed based on the quick-release hand-tightening buckle 9. Specifically, when the evaporator core 14 integrated module is inserted into the evaporator main housing, when the evaporator core 14 integrated module is completely retracted into the evaporator main housing, the quick-release hand-tightening buckle 9 on the evaporator core 14 integrated module passes through the side of the evaporator main housing, and then by rotation, the quick-release hand-tightening buckle 9 locks the evaporator core 14 integrated module and the evaporator main housing, thereby completing the connection between the evaporator core 14 integrated module and the evaporator main housing. Correspondingly, when it is necessary to pull out the evaporator core 14 integrated module, the quick-release hand-tightening buckle 9 is removed by rotating in the opposite direction first, so that the evaporator core 14 integrated module is no longer restricted, and then the evaporator core 14 integrated module can be pulled out from the evaporator main housing.

[0032] like Figure 1 , Figures 7 to 10 As shown, the quick-release hand-tightening buckle 9 includes a spring plate 92, a dovetail fin 91, and a handle 93. The handle 93 is fixedly connected to the bottom of the dovetail fin 91. The spring plate 92 is sleeved between the dovetail fin 91 and the handle 93. The main shell of the evaporator has a misalignment hole 182. A retaining strip 181 is fixedly connected to the main shell of the evaporator corresponding to the misalignment hole 182. The quick-release hand-tightening buckle 9 passes through the misalignment hole 182 through the dovetail fin 91 and can be locked or released by rotating 90°.

[0033] As described above, the quick-release hand-tightening buckle 9 is used to connect the evaporator main housing and the evaporator core 14 integrated module. In this embodiment, when the evaporator core 14 integrated module moves upward to fully retract into the evaporator main housing, the quick-release hand-tightening buckle 9 can pass through the misalignment hole 182 on the side of the evaporator main housing, and the dovetail fin 91 passes through the misalignment hole 182 and is positioned above the side of the evaporator main housing. Then, the handle 93 is controlled to rotate the quick-release hand-tightening buckle 9 by 90°, causing the dovetail fin 91 to misalign with the misalignment hole 182, thereby restricting the quick-release hand-tightening buckle 9 from passing through the misalignment hole 182 and from the evaporator. The main housing is separated. It is worth noting that in this embodiment, controlling the quick-release hand-tightening buckle 9 to rotate 90° is one implementation method, and it is not limited to rotating 90°. In addition, during the process of the quick-release hand-tightening buckle 9 passing through the misalignment hole 182 and rotating 90°, the spring plate 92 is compressed under the action of external force and always sticks to the evaporator main housing. When the external force disappears, the spring plate 92 can provide pre-tightening force, which, together with the self-weight of the evaporator core 14 integrated module, makes the swallowtail fin 91 always stick to the side surface of the evaporator main housing, realizing the connection between the evaporator core 14 integrated module and the evaporator main housing.

[0034] like Figures 1 to 6 As shown, the evaporator core 14 integrated module includes an evaporator core 14, a flexible piping assembly, and a mounting frame 2. The flexible piping assembly includes an evaporator liquid hose assembly 16 and an evaporator gas hose assembly 17, arranged in a curved path to allow the piping to change freely when pulled out. The flexible piping assembly and the evaporator core 14 are integrated on the mounting frame 2 to form a movable unit. The quick-release hand-tightening buckle 9 is rotatably connected to the edge of the mounting frame 2.

[0035] like Figures 7 to 10 As shown, the swallowtail wing 91 has symmetrically arranged notches 94 on one side relative to the locking strip 181. When the swallowtail wing 91 passes through the misalignment hole 182, it is rotated 90° to make the swallowtail wing 91 lock into the locking strip 181 for circumferential rotation limit.

[0036] Because the engineering vehicle may vibrate during operation, the quick-release hand-tightening buckle 9 may rotate and overlap with the misalignment hole 182. Under the weight of the evaporator core 14 integrated module, the quick-release hand-tightening buckle 9 may detach from the evaporator main housing, causing the evaporator core 14 integrated module to detach from the evaporator body 19. In this embodiment, when the maintenance personnel control the evaporator core 14 integrated module to fully retract into the evaporator main housing, the quick-release hand-tightening buckle 9 passes through the misalignment hole 182. At this time, it is rotated 90° and then released, so that the notch 94 at the bottom of the dovetail fin 91 corresponds to the locking strip 181. With the weight of the evaporator core 14 integrated module, the notch 94 of the dovetail fin 91 engages with the side of the locking strip 181. This limits the rotation of the quick-release hand-tightening buckle 9 caused by vibration, preventing the quick-release hand-tightening buckle 9 from detaching from the evaporator main housing. It is worth noting that since the evaporator core 14 integrated module has a certain weight, and the connection between the evaporator core 14 integrated module and the evaporator main housing relies solely on multiple arrayed quick-release hand-tightening buckles 9, the swallowtail fin 91 is always pressed against the side of the evaporator main housing under the weight of the evaporator core 14 integrated module. In this embodiment, the notch 94 of the swallowtail fin 91 is always pressed against the retaining strip 181, and a circumferential rotation limit is applied to the quick-release hand-tightening buckle 9, thereby preventing the quick-release hand-tightening buckle 9 from rotating due to vibration, which would then cause the evaporator core 14 integrated module to separate from the evaporator main housing.

[0037] like Figures 1 to 7 As shown, it also includes a waterproof sealing ring 12, which is set at the flange mating surface between the evaporator core 14 integrated module and the evaporator main shell to prevent condensate from overflowing and sand and dust from entering.

[0038] like Figures 1 to 7 As shown, the evaporator body 19 is provided with an evaporator access cover 1 for accessing the evaporator core 14 integrated module. The evaporator access cover 1 can be opened to expose the pull-out path.

[0039] like Figures 1 to 7 As shown, the evaporator core 14 integrated module also includes a condensate drainage system, which includes a water collection box 7, a first drain hose 3, a second drain hose 10, and a drain tee 11, for collecting and draining condensate, and is integrated with the refrigeration system in the same module.

[0040] Working Principle: By setting up a pull-out guide mechanism, the evaporator core 14 integrated module can be smoothly pulled out of the evaporator body 19, specifically from the evaporator main housing, along the guide rail. This facilitates quick on-site cleaning or replacement of the filter element and fin assembly by maintenance personnel, effectively reducing maintenance difficulty and downtime. Simultaneously, the sealed structure design ensures that refrigerant leakage will not occur due to vibration during normal use. Specifically, when the evaporator of an engineering vehicle's air conditioning system becomes clogged due to prolonged exposure to sand and dust, causing a decrease in heat exchange efficiency, maintenance personnel manually pull out the evaporator core 14 integrated module. This allows the module to slide out of the evaporator main housing along the predetermined sliding direction of the pull-out guide mechanism. Once the evaporator core 14 integrated module is removed from the evaporator main housing, it is exposed, allowing for direct cleaning or replacement of the evaporator core 14 integrated module without disassembling the evaporator and its associated piping. This facilitates the maintenance of the evaporator core 14 integrated module. More convenient and with a shorter maintenance cycle; multiple steel wire rope anchor points 6 are arranged and fixed to the side walls of the evaporator core 14 integrated module and the evaporator main shell, respectively. The two ends of the limiting steel wire rope 5 are respectively connected to two parallel steel wire rope anchor points 6 to limit the pull-out limit position of the evaporator core 14 integrated module. It can be foreseen that when the evaporator core 14 integrated module is retracted in the evaporator main shell, the limiting steel wire rope 5 is bent and retracted in the evaporator body 19. When the evaporator core 14 integrated module needs to be cleaned or replaced, the evaporator core 14 integrated module is pulled out of the evaporator main shell. The displacement path of the evaporator core 14 integrated module is guided by the pull-out guide rail 4, so that the evaporator core 14 integrated module slides out smoothly. In addition, the limiting steel wire rope 5 can limit the evaporator core 14 integrated module, so that the evaporator core 14 integrated module stops after sliding to the limit position, thereby avoiding the evaporator core 14 integrated module from slipping and causing damage.

[0041] In this embodiment, the separation efficiency of the evaporator core 14 integrated module from the evaporator main housing is achieved based on the quick-release hand-tightening buckle 9. Specifically, when the evaporator core 14 integrated module is inserted into the evaporator main housing, and the module is fully retracted within it, the quick-release hand-tightening buckle 9 on the module passes through the side of the evaporator main housing, and then, by rotation, locks the evaporator core 14 core 14 integrated module with the quick-release hand-tightening buckle 9. The core 14 integrated module is connected to the evaporator main housing, thus completing the connection between the evaporator core 14 integrated module and the evaporator main housing. Correspondingly, when it is necessary to pull out the evaporator core 14 integrated module, the quick-release hand-tightening buckle 9 is removed by rotating it in the reverse direction first, so that the evaporator core 14 integrated module is no longer restricted, and then the evaporator core 14 integrated module can be pulled out from the evaporator main housing. Controlling the quick-release hand-tightening buckle 9 to rotate 90° is one implementation method, and it is not limited to rotating 90°. In addition, the quick-release hand-tightening buckle 9... During the process of passing through the misalignment hole 182 and rotating 90°, the spring plate 92 is compressed under the action of external force and always remains in close contact with the main shell of the evaporator. When the external force disappears, the spring plate 92 can provide pre-tension force, which, together with the weight of the integrated module of the evaporator core 14, ensures that the swallowtail fin 91 remains in close contact with the side surface of the main shell of the evaporator, thus achieving the connection between the integrated module of the evaporator core 14 and the main shell of the evaporator. It is worth noting that, due to the certain weight of the integrated module of the evaporator core 14, and the fact that the integrated module of the evaporator core 14 has a certain weight, the connection between the integrated module of the evaporator core 14 and the main shell of the evaporator is achieved. The connection between the block and the main evaporator housing relies solely on multiple arrayed quick-release hand-tightening clips 9. Therefore, under the weight of the evaporator core 14 integrated module, the dovetail fin 91 is always pressed against the side of the main evaporator housing. In this embodiment, the notch 94 of the dovetail fin 91 is always pressed against the retaining strip 181 and applies circumferential rotation limit to the quick-release hand-tightening clip 9, thereby preventing vibration from causing the quick-release hand-tightening clip 9 to rotate, which in turn causes the evaporator core 14 integrated module to separate from the main evaporator housing.
