Description

Technical Field

[0001] This utility model relates to the field of heat pump evaporator technology, specifically a heat pump evaporator structure. Background Technology

[0002] The heat pump evaporator is the core component of a heat pump system, primarily used to absorb low-temperature heat from the environment. Its working principle is as follows: as the liquid refrigerant flows within the evaporator, it exchanges heat with low-temperature heat sources such as ambient air or water, absorbing heat and evaporating into a low-temperature, low-pressure gaseous state. This process continuously extracts heat energy from the heat source side, providing the basis for the heat pump's compression and condensation heat release processes. Heat pump evaporators are characterized by high efficiency and energy saving, and are widely used in heating, drying, and industrial evaporation and concentration applications.

[0003] An evaporator for a solar heat pump disclosed in Chinese Patent Publication No. CN109028663A has heat dissipation fins on both the left and right outer walls of the outer shell. At the same time, an air collection box is set outside the heat dissipation fins. The air collection box can collect the dissipated heat, thereby generating hot air at a higher temperature. The hot air flows into the protective base at the bottom of the outer shell, preventing frost from forming at the outlet of the evaporator's outer shell, so that the evaporator can continue to be used in winter.

[0004] However, the heat pump evaporator has a single functional structure, and the internal water tank can become clogged with scale after long-term use, making it difficult to clean quickly and efficiently. At the same time, the fixed position of the device makes it difficult to carry out quick internal inspection and maintenance, thus affecting the long-term stability of the heat pump evaporator structure. Utility Model Content

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

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat pump evaporator structure, including a fixed base, a controller fixedly connected to the right side of the front end of the fixed base, a liquid storage chamber opened at the center of the interior of the fixed base, an mounting base provided inside the top of the fixed base, a water supply pipe fixedly connected to the center of the left side of the interior of the mounting base, a cold liquid pipe fixedly connected to the outside of the water supply pipe, a condenser fixedly connected to the bottom end of the right side of the interior of the mounting base, the left side of the condenser communicating with the cold liquid pipe, a liquid storage tank provided at the top of the condenser, a water pump provided at the top of the liquid storage tank, a return pipe fixedly connected to the output end of the water pump, the left side of the return pipe communicating with the cold liquid pipe, gas storage chambers fixedly connected to the left and right sides of the exterior of the mounting base, and a limiting mechanism for connecting and assembling the fixed base and the mounting base.

[0007] Preferably, a drain port is fixedly connected to the bottom right side of the liquid storage chamber, air inlets are opened on the left and right sides of the upper surface of the liquid storage chamber, and a delivery port is fixedly connected to the left side of the center position of the upper surface of the fixed base, with the top of the delivery port connected to the water outlet of the water delivery pipe.

[0008] Preferably, the water supply pipe is S-shaped and installed inside the mounting base, the cold liquid pipe is wrapped around the outside of the water supply pipe, and the cold liquid pipe is fixed in position by a fixing ring inside the mounting base. The condenser, the liquid storage tank, and the water pump are connected by a transmission pipeline.

[0009] Preferably, heat dissipation fins are uniformly and vertically fixed inside the gas storage chamber, and an input pipe is fixed to the bottom of the outer side of the gas storage chamber. An insertion tube that is inserted into the air inlet is fixed to the bottom end of the input pipe, and rubber pads are provided on the contact surfaces of the air inlet and the insertion tube.

[0010] Preferably, the limiting mechanism includes a motor fixedly connected to the center of the top end inside the fixed base, a take-up shaft installed on the output shaft end of the motor, an elastic pull rope fixedly connected to the four sides of the outer side of the take-up shaft, a moving block fixedly connected to the outer side of the elastic pull rope, a spring fixedly connected to the inner side of the moving block, a locking block fixedly connected to the top of the moving block, and a positioning groove for engaging with the locking block is provided around the four sides of the bottom end of the mounting base.

[0011] Preferably, a scraper is coaxially fixed to the bottom end of the winding shaft. The scraper is disposed inside the liquid storage cavity, and the liquid storage cavity is cylindrical with an internal diameter that is the same as the length of the scraper.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This type of heat pump evaporator structure features positioning grooves around the bottom of the mounting base. When the locking blocks on the fixed base engage with the positioning grooves on the mounting base, the connection and assembly of the fixed base and the mounting base can be completed. When maintenance of the mounting base is required, the motor inside the fixed base is started, which drives the winding shaft to rotate. At this time, the winding shaft pulls four sets of elastic ropes to wind up, and the elastic ropes can pull the locking blocks to move through the moving blocks. When the locking blocks release their restriction on the positioning grooves, the fixed base and the mounting base can be quickly separated, allowing for rapid maintenance of the mounting base. Simultaneously, the rotation of the winding shaft drives the scraper below to rotate synchronously within the liquid storage chamber. The scraper can effectively clean the inner wall of the liquid storage chamber, ensuring the long-term stability of the liquid storage chamber and improving the overall functionality and practicality of the heat pump evaporator.

The left side of the return pipe 503 is connected to the cold liquid pipe 4. The left and right sides of the mounting base 2 are fixedly connected to the gas storage chamber 6. The controller 101 can control and start the electrical equipment inside the fixed base 1. The condenser 5 can work with the liquid storage tank 501 to quickly cool the water. At the same time, the water pump 502 can start to input the cold liquid into the cold liquid pipe 4 through the return pipe 503 and exchange heat with the water in the water supply pipe 3. The heat generated during the heat exchange process can be dissipated through the heat dissipation fins 601 and enter the interior of the liquid storage chamber 102 through the gas storage chamber 6, while providing auxiliary heating for the water in the liquid storage chamber 102.

[0019] A drain port 103 is fixedly connected to the bottom right side of the liquid storage chamber 102. Air inlets 104 are provided on the left and right sides of the upper surface of the liquid storage chamber 102. A delivery port 105 is fixedly connected to the left side of the center position of the upper surface of the fixed base 1. The top of the delivery port 105 is connected to the water outlet of the water pipe 3. The drain port 103 can drain water from the inside of the liquid storage chamber 102. At the same time, the water in the water pipe 3 can enter the inside of the liquid storage chamber 102 through the delivery port 105.

[0020] The water supply pipe 3 is installed in an S-shape inside the mounting base 2. The cold liquid pipe 4 is wrapped around the outside of the water supply pipe 3 and is fixed in position by the fixing ring inside the mounting base 2. The condenser 5, the liquid storage tank 501, and the water pump 502 are connected by a transmission pipeline.

[0021] The gas storage chamber 6 has heat dissipation fins 601 that are evenly and vertically fixed inside. The bottom of the outer side of the gas storage chamber 6 is fixed with an input pipe 602. The bottom end of the input pipe 602 is fixed with an insertion pipe 603 that is inserted into the air inlet 104. The contact surfaces of the air inlet 104 and the insertion pipe 603 are both provided with rubber pads. The heat dissipation fins 601 are made of copper to facilitate rapid heat dissipation. At the same time, the hot air in the gas storage chamber 6 can enter the interior of the liquid storage chamber 102 through the input pipe 602 and the insertion pipe 603.

[0022] Example 2 The difference from Embodiment 1 is that this embodiment discloses a limiting mechanism and a scraper 8 for installing and removing the fixing base 1 and the mounting base 2: The limiting mechanism includes a motor 7 fixedly connected to the center of the top end inside the fixed base 1. A winding shaft 701 is installed on the output shaft end of the motor 7. An elastic pull rope 702 is fixedly connected to the outer perimeter of the winding shaft 701. A moving block 703 is fixedly connected to the outer side of the elastic pull rope 702. A spring 704 is fixedly connected to the inner side of the moving block 703. A locking block 705 is fixedly connected to the top of the moving block 703. A positioning groove 201 is provided around the bottom of the mounting base 2 to engage with the locking block 705. The locking block 705 can pass through when subjected to a downward force. When the moving block 703 compresses the spring 704, the locking block 705 can move toward the center position inside the fixed seat 1. When the mounting seat 2 is fully inserted into the fixed seat 1, the reaction force of the spring 704 being compressed can push the locking block 705 through the moving block 703 to complete the limiting work of the positioning groove 201 at the bottom of the mounting seat 2. When the motor 7 starts and drives the winding shaft 701 to rotate, the winding shaft 701 pulls the elastic rope 702 to wind up. The elastic rope 702 can then pull the locking block 705 to move through the moving block 703.

[0023] A scraper 8 is coaxially fixed to the bottom end of the take-up shaft 701. The scraper 8 is disposed inside the liquid storage cavity 102, and the liquid storage cavity 102 is cylindrical with an internal diameter that is the same as the length of the scraper 8. When the take-up shaft 701 drives the scraper 8 to rotate, the scraper 8 can rotate inside the liquid storage cavity 102. At this time, the scraper 8 can scrape and clean the inner wall of the liquid storage cavity 102. Meanwhile, the contents not described in detail in this specification are all prior art known to those skilled in the art.

[0024] In this embodiment, the mounting base 2 is placed at the center of the top of the fixed base 1. The insertion tube 603 at the bottom of the gas storage chamber 6 can be inserted into the air inlet 104 on the fixed base 1. The bottom end of the water supply pipe 3 inside the mounting base 2 can connect with the liquid inlet 105 on the fixed base 1. Simultaneously, the locking block 705 on the fixed base 1 can engage with the positioning groove 201 on the mounting base 2 to limit the mounting base 2's position. External water can enter the water supply pipe 3 through the inlet at the top of the mounting base 2. Simultaneously, the condenser 5, in conjunction with the liquid storage tank 501, can quickly cool the water. At the same time, the water pump 502 is activated to pump the cooled liquid through… The return pipe 503 enters the cold liquid pipe 4 and exchanges heat with the water in the water supply pipe 3. The heat generated during the heat exchange process can be dissipated through the heat dissipation fins 601 and enter the interior of the liquid storage chamber 102 through the air storage chamber 6, while providing auxiliary heating for the water in the liquid storage chamber 102. When the mounting base 2 needs to be inspected and maintained, the motor 7 is started. At this time, the motor 7 drives the winding shaft 701 to rotate, and the winding shaft 701 pulls the elastic rope 702 to wind up. At the same time, the elastic rope 702 can drive the locking block 705 through the moving block 703 to release the limit on the positioning groove 201 on the mounting base 2, so that the mounting base 2 can be removed from the top of the fixed base 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
