Description

Technical Field

[0001] The invention belongs to the field of heat exchangers, and in particular relates to a plate heat exchanger for an air source heat pump. Background Art

[0002] Heat exchangers are widely used in air conditioning systems, hot water supply, HVAC equipment, and other fields. They primarily regulate fluid temperature through heat exchange. Their basic principle is to utilize heat exchange between hot and cold fluids to transfer heat energy from one fluid to another, thereby achieving temperature regulation. In a heat exchanger, heat transfer plates serve as a key heat transfer medium, facilitating efficient heat transfer through their extensive heat exchange surface area in contact with the fluid.

[0003] Heat exchange plates usually have a corrugated structure or other special designs to increase the heat exchange surface area, optimize the flow characteristics of the fluid, and thus improve the heat exchange efficiency.

[0004] Existing heat exchange plate installation methods usually require the use of multiple screws for fixing. The screws need to be manually operated, which is time-consuming, labor-intensive and error-prone during installation. At the same time, these screws are exposed to the outside and often come into contact with moisture, making them prone to rust or corrosion, thereby affecting the long-term use of the heat exchanger. In addition, when the temperature is low, frost may form on the surface of the heat exchange plate, resulting in a decrease in heat exchange efficiency. Frost not only affects the flow of the fluid, but also deteriorates the thermal conductivity of the heat exchange surface, thereby affecting the overall performance and energy efficiency of the heat exchanger. On the other hand, before entering the heat exchanger, the fluid often carries some impurities. Due to the lack of effective filtering devices in the existing technology, these impurities may enter the interior of the heat exchanger, causing contamination or blockage of the heat exchange plate and internal flow channels. The accumulation of impurities not only reduces the heat exchange efficiency of the heat exchanger, but may also damage the equipment and shorten its service life. Summary of the Invention

The pull ring is pulled to take the filter plate out of the liquid inlet channel through the connecting rod, and the filter plate can be cleaned at this time.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When using the heat exchanger of the present invention, multiple heat exchange plates have a corrugated structure, which increases the area of the heat exchange surface, optimizes the flow characteristics of the fluid, and transfers energy through heat exchange between the multiple heat exchange plates. When installing multiple heat exchange plates, the upper and lower sides of the multiple heat exchange plates can slide on the opposite sides of the two guide rods respectively. By clamping the multiple heat exchange plates on the two guide rods, the outer surface of the two-way threaded rod has two thread grooves with different rotation directions, and the two slides are respectively connected to them. At the same time, the rear end plate can slide on the inner walls of the two guide rods, and then when the two-way threaded rod rotates, the two slides do not rotate together. Furthermore, the two slides can move in different directions on the outer surface of the two-way threaded rod, and the two-way threaded rod is driven by the clockwise rotation of the adjustment plate. The threaded rod rotates, and the two slides move relative to each other on the outer surface of the bidirectional threaded rod. The two fixed plates can rotate with the two first connecting shafts or the two second connecting shafts as axes. When the two slides move in relative directions, the distance between the two fixed plates on one side will increase, further pushing the convex plate forward. When the two slides move in opposite directions, the distance between the two fixed plates will decrease, further pulling the convex plate backward. At this time, the two slides move relative to each other and push the convex plate through the two fixed plates, further allowing the rear end plate and the front end plate to fix multiple heat exchange plates, completing the installation of multiple heat exchange plates. Therefore, when using the heat exchanger, the installation method of multiple heat exchange plates is simple, without rotating multiple screws, reducing the installation and disassembly time of the heat exchanger.

[0017] 2. In the present invention, when using the heat exchanger, the cap on the water inlet pipe is removed by rotating, and water is poured into the water inlet pipe. At this time, the circulation pump is turned on to allow water to flow through specific pipes. That is, under the action of the circulation pump, the water passes through the first guide pipe, the second guide pipe, the heating pipe, the third guide pipe, the two branch pipes, and the plurality of branch pipes. When the water passes through the heating pipe, the plurality of electric heating rods are in an open state. The plurality of electric heating rods are energized to heat the heating pipe, further heating the water passing through the heating pipe. The plurality of electric heating rods are prevented from being exposed to the outside by the insulation sleeve, thereby preventing heat from overflowing. When the water passes through the plurality of branch pipes, the baffle can slide on one side of the base, and the sliding baffle exposes the plurality of notches. At this time, the external power switch of the small fan is turned on, and air is blown into the interior of the bottom box through the ventilation pipe, blowing the hot air emitted from the plurality of branch pipes upward and further blowing the hot air onto the plurality of heat exchange plates to melt frost. Therefore, when the heat exchanger is used, frost on the heat exchange surface can be removed, the heat exchange efficiency of the heat exchanger can be restored, and the increased energy consumption caused by frost can be avoided.

[0018] 3. When the heat exchanger of the present invention is in use, the fluid enters the interior of the heat exchanger through the liquid inlet channel, and impurities in the fluid are filtered out by the filter plate. After a period of use, the pipe connected to the liquid inlet channel is disassembled, and the filter plate can be slid on the inner wall of the liquid inlet channel. The pull ring is pulled to take the filter plate out of the interior of the liquid inlet channel through the connecting rod. At this time, the filter plate can be cleaned. During installation, the two metal springs have elastic force, and the pull ring pushes the filter plate so that the filter plate rests on one side of the pull ring. At this time, the two metal springs are squeezed by the inner wall of the liquid inlet channel through the two curved plates. The filter plate is clamped to the interior of the liquid inlet channel by the elastic force of the two metal springs, completing the installation of the filter plate. When the heat exchanger is in use, the incoming fluid is filtered to prevent impurities in the fluid from contaminating or clogging the surface and internal flow channel of the heat exchanger, thereby affecting the heat exchange effect.

A plurality of heat exchange plates 211 are movably embedded on the opposite side of the two guide rods 201.

[0031] When in use, the multiple heat exchange plates 211 have a corrugated structure, which increases the area of the heat exchange surface and optimizes the flow characteristics of the fluid. Energy is transferred through heat exchange between the multiple heat exchange plates 211. When the multiple heat exchange plates 211 are installed, the upper and lower sides of the multiple heat exchange plates 211 can slide on the opposite side of the two guide rods 201 respectively.

At the same time, the rear end plate 203 can slide on the inner walls of the two guide rods 201, and then when the two-way threaded rod 204 rotates, the two slides 205 do not rotate together. Further, the two slides 205 can move in different directions on the outer surface of the two-way threaded rod 204.

When the two slides 205 move in opposite directions, the distance between the two fixed plates 207 is reduced, and the protruding plate 209 is further pulled backward. At this time, the two slides 205 move relative to each other and push the protruding plate 209 through the two fixed plates 207, further making the rear end plate 203 and the front end plate 2 fix multiple heat exchange plates 211, completing the installation of multiple heat exchange plates 211.

[0039] See also Figures 1 to 9In one embodiment, an arc-shaped plate 404 is fixedly provided on the opposite sides of the two metal springs 403, and a pull ring 405 is fixedly provided at one end of the connecting rod 402. The pull ring 405 is pulled to take the filter plate 401 out of the liquid inlet channel 4 through the connecting rod 402. At this time, the filter plate 401 can be cleaned.

[0040] The working principle and usage process of the present invention: When using the heat exchanger, multiple heat exchange plates 211 have a corrugated structure, which increases the area of the heat exchange surface, optimizes the flow characteristics of the fluid, and transfers energy through heat exchange between the multiple heat exchange plates 211. When installing multiple heat exchange plates 211, the upper and lower sides of the multiple heat exchange plates 211 can slide on the opposite side of the two guide rods 201 respectively. By clamping the multiple heat exchange plates 211 on the two guide rods 201, the outer surface of the two-way threaded rod 204 has two thread grooves with different rotation directions, and the two slides 205 are respectively connected to them. At the same time, the rear end plate 203 can slide on the inner walls of the two guide rods 201, and then when the two-way threaded rod 204 rotates, the two slides 205 do not rotate together. Further, the two slides 205 can move in different directions on the outer surface of the two-way threaded rod 204, and the two-way threaded rod 204 is driven by clockwise rotation of the adjustment plate 210. The threaded rod 204 rotates, and the two slides 205 move relative to each other on the outer surface of the bidirectional threaded rod 204. The two fixed plates 207 can rotate with the two first connecting shafts 206 or the two second connecting shafts 208 as axes. When the two slides 205 move in relative directions, the distance between the two fixed plates 207 is increased, and the protruding plate 209 is further pushed forward. When the two slides 205 move in opposite directions, the distance between the two fixed plates 207 is reduced, and the protruding plate 209 is further pulled backward. At this time, the two slides 205 move relative to each other and push the protruding plate 209 through the two fixed plates 207, further making the rear end plate 203 and the front end plate 2 fix the multiple heat exchange plates 211, completing the installation of the multiple heat exchange plates 211. Therefore, when the heat exchanger is used, the installation method of the multiple heat exchange plates 211 is simple, without rotating multiple screws, reducing the installation and disassembly time of the heat exchanger. When using the heat exchanger, the screw cap on the water inlet pipe 310 is removed by rotating, and water is poured into the water inlet pipe 310. At this time, the switch of the circulation pump 304 is turned on to make the water flow in a specific pipe. That is, under the action of the circulation pump 304, the water passes through the first guide pipe 303, the second guide pipe 305, the heating pipe 306, the third guide pipe 309, the two branch pipes 301 and the multiple branch pipes 301. When the water passes through the interior of the heating pipe 306, the multiple electric heating rods 307 are in the open state. The multiple electric heating rods 307 are energized to heat the heating pipe 306, and further heat the water passing through the interior of the heating pipe 306. The heat-insulating sleeve 308 prevents the multiple electric heating rods 307 from being exposed and prevents heat from escaping. When water passes through the multiple branch pipes 301, the baffle 313 can slide on one side of the base 1, exposing the multiple notches 314 by sliding the baffle 313. At this time, the external power switch of the small fan 311 is turned on, and air is blown into the bottom box 3 through the ventilation pipe 312, blowing the hot air emitted from the multiple branch pipes 301 upward and further onto the multiple heat exchange plates 211 to melt frost. Therefore, when the heat exchanger is in use, frost on the heat exchange surface can be removed, the heat exchange efficiency of the heat exchanger can be restored, and the increased energy consumption caused by frost can be avoided. When the heat exchanger is in use, fluid enters the interior of the heat exchanger through the liquid inlet channel 4, and impurities in the fluid are filtered out by the filter plate 401. After a period of use, the pipe connected to the liquid inlet channel 4 is removed, and the filter plate 401 can be slid on the inner wall of the liquid inlet channel 4. The pull ring 405 is pulled to remove the filter plate 401 from the interior of the liquid inlet channel 4 through the connecting rod 402. At this time, the filter plate 401 can be cleaned. During installation, the two metal springs 403 have elastic force. The pull ring 405 pushes the filter plate 401 so that the filter plate 401 is against one side of the pull ring 405. At this time, the two metal springs 403 are squeezed by the inner wall of the liquid inlet channel 4 through the two curved plates 404. The elastic force of the two metal springs 403 locks the filter plate 401 into the interior of the liquid inlet channel 4, completing the installation of the filter plate 401. Therefore, when the heat exchanger is in use, the incoming fluid is filtered to prevent impurities in the fluid from contaminating or clogging the surface and internal flow channel of the heat exchanger, thereby affecting the heat exchange effect.
