Description

Technical Field

[0001] This utility model belongs to the field of evaporator technology, specifically relating to an evaporator for compressor units. Background Technology

[0002] The evaporator is one of the core components of a refrigeration system. For compressor units, the evaporator plays a crucial role. Its main function is to absorb heat from the object being cooled through the evaporation of refrigerant at low pressure, thus achieving cooling. In the refrigeration cycle, the evaporator is located on the low-pressure side of the compressor. Inside the evaporator, the refrigerant passes through the expansion valve, where it is depressurized, changing from a liquid to a gaseous state and absorbing heat from the surrounding environment. It is then compressed again by the compressor and returns to the condenser for condensation, completing a full refrigeration cycle.

[0003] Existing evaporators do not filter the incoming liquid, allowing impurities and sediments in the liquid to enter the evaporator, which can easily affect its operation. Furthermore, dirt remains on the heating element at the bottom of the evaporator after the liquid evaporates, affecting subsequent evaporation. Existing evaporators are usually difficult to clean.

[0027] This embodiment proposes an evaporator for a compressor unit, the overall structure of which is as follows: Figure 1 and 2 As shown, it mainly includes a box body 1, a top cover 2, a filter device 3, a lifting door 4, and a heating device 5.

[0028] The housing 1 is a cuboid structure with an open top. The top cover 2 is fixedly installed on the top of the housing 1 by connectors. The top of the top cover 2 is fixedly installed with a steam outlet 201 by welding. The top cover 2 adopts a hollow pyramidal structure to facilitate the outflow of evaporated gas.

[0029] A liquid inlet 101 is fixedly connected to the side panel of the housing 1 for introducing the liquid to be evaporated into the housing 1. The front panel of the housing 1 is machined with an operation port for the filter device located on the upper side and an operation port for the heating device located on the lower side.

[0030] A lifting door 4 is installed inside the operating port of the filter device in housing 1, such as... Figure 3 As shown, the lifting door 4 includes a door body, a first drive motor 401, and a first lead screw 402. Threaded holes are machined at both ends of the door body, and two first lead screws 402 are inserted into one of these holes. The bottom of each first lead screw 402 is connected to the output shaft of a first drive motor 401 via a fastener. The two first drive motors 401 are mounted on the inner wall of the housing 1. The operation of the first drive motors 401 drives the first lead screws 402 to rotate, which in turn drives the door body to rise and fall, thereby opening and closing the operating port of the filter device. To improve the sealing effect, a sealing strip 403 is adhered to the top of the door body.

[0031] The inner walls of the two side panels of the housing 1 are respectively fixed with protrusions 102 by welding. The filter device 3 is used to filter the incoming liquid to be evaporated, such as... Figure 4 As shown, the filter device 3 includes a frame, a handle 301, a filter screen 302, and a fixing post 303. The handle 301 is mounted on the front panel of the frame, and grooves 304 are provided on both sides of the frame. Two protrusions 102 are embedded into the corresponding grooves 304, allowing the filter device 3 to be pushed and pulled at the filter device operation port of the housing 1. The filter screen 302 is inserted into the frame through an opening in the front panel. The fixing post 303 is installed inside the frame, penetrating the filter screen 302 to secure it. The filter screen 302 can be removed by pulling out the fixing post 303. After replacing the filter screen 302, the fixing post 303 is reinserted to secure the filter screen 302, facilitating filter screen replacement.

[0032] The heating device 5 is used to evaporate the liquid to be evaporated after being filtered by the filter device 3, and to discharge the evaporated gas through the steam outlet 201. Figure 5As shown, the heating device 5 includes a tray, a drive block 501, a baffle 502, a sealing ring 503, heating rods 504, a second lead screw 505, and a second drive motor 506. The tray holds the liquid to be evaporated, and multiple heating rods 504 for heating and evaporating the liquid are fixedly installed inside the tray. The baffle 502 is fixedly connected to the front panel of the tray by welding, and a sealing ring 503 is bonded to the inner side of the baffle 502 to prevent liquid leakage. The drive block 501 is connected to the rear side of the tray by fasteners. The rear end of a second lead screw 505 is connected to the output shaft of a second drive motor 506 by fasteners. The second drive motor 506 is mounted on the inner wall of the housing 1, and the front end of the second lead screw 505 is threaded to the drive block 501. The operation of the second drive motor 506 drives the second lead screw 505 to rotate, which in turn moves the drive block 501, causing the tray to move back and forth, thus enabling the tray to enter and exit the operating port of the heating device.

[0033] A battery is installed at the bottom of the housing 1. One end of the battery is connected to the first drive motor 401, the second drive motor 506 and the heating rod 504, and the other end is connected to an external control terminal. The battery is controlled to supply power to the first drive motor 401, the second drive motor 506 and the heating rod 504 according to the instructions to complete the corresponding work.

[0034] Working principle: Liquid enters through liquid inlet 101, passes through filter device 3 to filter impurities, and then flows into heating device 5. When the device is no longer in use and needs to be cleaned, the first drive motor 401 is started to open the lifting door 4, allowing the filter device 3 to be removed. When the filter screen 302 in the filter device 3 needs to be replaced after long-term use, the filter screen 302 can be pulled out by pulling out the fixing column 303. This device can filter liquid while facilitating the cleaning of filter device 3 and the replacement of filter screen 302. When the heating device 5 needs to be cleaned after long-term use, the second drive motor 506 is started, driving the second lead screw 505 to rotate. The second lead screw 505 drives the drive block 501 to move, and the drive block 501 can then move the heating device 5 out of the housing 1 for easy cleaning.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
