Energy-saving evaporator micro-channel heat dissipation structure

Abstract

This utility model discloses a microchannel heat dissipation structure for an energy-saving evaporator, comprising: a mounting frame, a U-shaped tube mounted on the mounting frame, an inlet pipe and an outlet pipe respectively connected to both sides of the U-shaped tube, and further comprising: multiple equidistant microchannels installed inside the U-shaped tube. A horizontal plate is installed on the outer wall of the U-shaped tube, and an opening and closing component is installed on the top outer wall of the horizontal plate. This energy-saving evaporator microchannel heat dissipation structure, through the arrangement of multiple microchannels, forms multiple microchannels inside the U-shaped tube, effectively increasing the contact area with air and improving the heat exchange effect. As the working time increases, dust in the air will adhere to the surface of the microchannels, reducing the heat exchange effect. The opening and closing component can open two strip-shaped openings on the surface of the U-shaped tube, providing space for the dust scraping component to move up and down. The descent of the dust scraping component can scrape off the dust from the surface of the multiple microchannels.

Description

Technical Field

[0001] This utility model relates to the field of evaporator heat dissipation technology, specifically to an energy-saving evaporator microchannel heat dissipation structure. Background Technology

[0002] The evaporator is a crucial component of the four main refrigeration systems. Low-temperature condensate passes through the evaporator, where it exchanges heat with the outside air, vaporizing and absorbing heat to achieve a cooling effect. Currently, most evaporators use a single pipe for the condensate, limiting the heat exchange area and hindering its efficiency. Therefore, we propose an energy-saving microchannel heat dissipation structure for the evaporator to address these issues. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a microchannel heat dissipation structure for an energy-saving evaporator, comprising: a mounting frame, a U-shaped tube mounted on the mounting frame, an inlet pipe and an outlet pipe respectively connected to both sides of the U-shaped tube, and further comprising: multiple microchannels evenly distributed inside the U-shaped tube, a horizontal plate mounted on the outer wall of the U-shaped tube, an opening and closing component mounted on the top outer wall of the horizontal plate, a dust scraping component mounted on the bottom outer wall of the horizontal plate, and a sealing component mounted on the mounting frame, and a strip-shaped opening on the opposite outer wall of the U-shaped tube, and an arc-shaped opening at the bottom of the U-shaped tube.

[0005] The opening and closing assembly includes a dual-slide linear motor, connecting rods mounted on the bottom of the two sliding parts of the dual-slide linear motor, and strip plates mounted on the bottom of the two connecting rods.

[0006] The strip plate is adapted to the strip opening.

[0011] This utility model discloses an energy-saving evaporator microchannel heat dissipation structure. By setting multiple microchannels, multiple microchannels are formed inside the U-shaped tube, which effectively increases the contact area with air and improves the heat exchange effect. As the working time increases, dust in the air will adhere to the surface of the microchannels, which will reduce the heat exchange effect. The two strip openings on the surface of the U-shaped tube can be opened by the opening and closing component to provide space for the dust scraping component to move up and down. By lowering the dust scraping component, the dust on the surface of multiple microchannels can be scraped off. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-7The present invention provides an energy-saving evaporator microchannel heat dissipation structure, comprising: a mounting frame 1, a U-shaped tube 2 mounted on the mounting frame 1, an inlet pipe 3 and an outlet pipe 4 respectively connected to both sides of the U-shaped tube 2, and further comprising: multiple microchannels 5 evenly distributed inside the U-shaped tube 2, a horizontal plate 7 mounted on the outer wall of the U-shaped tube 2, an opening and closing component 6 mounted on the top outer wall of the horizontal plate 7, a dust scraping component 8 mounted on the bottom outer wall of the horizontal plate 7, and a sealing component 9 mounted on the mounting frame 1, and strip-shaped openings 10 on opposite sides of the outer wall of the U-shaped tube 2, and an arc-shaped opening 11 at the bottom of the U-shaped tube 2.

[0022] It should be noted that: condensate flows into the U-shaped tube 2 from one end, enters multiple microchannels 5, and then flows out from the other end of the microchannels 5. Air can enter the U-shaped tube 2 through the air inlet pipe 3 for heat exchange, and then flows out through the air outlet pipe 4. Through the multiple microchannels 5, multiple microchannels are formed inside the U-shaped tube 2, which effectively increases the contact area with air and improves the heat exchange effect. As the working time increases, dust in the air will adhere to the surface of the microchannels 5, which will reduce the heat exchange effect. The two strip openings 10 on the surface of the U-shaped tube 2 can be opened by the opening and closing component 6 to provide space for the dust scraping component 8 to move up and down. The dust on the surface of the multiple microchannels 5 can be scraped off by the descent of the dust scraping component 8 and eventually accumulate at the bottom of the U-shaped tube 2. The arc opening 11 can be opened by the sealing component 9 to facilitate the cleaning of dust.

[0023] In a preferred embodiment, the opening and closing assembly 6 includes a double-slide linear motor 601, connecting rods 602 mounted on the bottom of the two sliding parts of the double-slide linear motor 601, and a strip plate 603 mounted on the bottom of the two connecting rods 602; the strip plate 603 is adapted to the strip opening 10.

[0024] It should be noted that the dual-slide linear motor 601 can drive the two connecting rods 602 to move closer to each other, which in turn drives the two strip plates 603 to move closer to each other, opening the two strip openings 10.

[0025] In a preferred embodiment, the scraping assembly 8 includes a mounting frame 801, a motor 802 mounted on the inner wall of the mounting frame 801, a threaded rod 803 connected to the bottom of the output shaft of the motor 802, a lifting block 804 screwed onto the threaded rod 803, a fixing frame 805 mounted on the outer walls of both sides of the lifting block 804, and a perforated plate 806 mounted on one end of the two fixing frames 805.

[0026] It should be noted that the two connecting rods 602 and the two strip plates 603, after being brought close together, are located below the hollow parts of the two fixed frames 805, which does not affect the up and down movement of the two fixed frames 805. The threaded rod 803 can be rotated by the motor 802, which in turn drives the two fixed frames 805 and the two perforated plates 806 to descend. The descent of the two perforated plates 806 can scrape off the dust on the surfaces of the two ends of the multiple micro-tubes 5.

[0027] In a preferred embodiment, the sealing assembly 9 includes an electric push rod 901 and an arc-shaped plate 902 mounted on the top of the piston rod of the electric push rod 901; the arc-shaped plate 902 is adapted to the arc-shaped opening 11.

[0028] It should be noted here that the electric push rod 901 can drive the arc plate 902 to descend, opening the arc opening 11.

[0029] Working principle: Condensate flows into the U-shaped tube 2 from one end, enters multiple microchannels 5, and then flows out from the other end of the microchannels 5. Air enters the U-shaped tube 2 through the inlet pipe 3 for heat exchange and then flows out through the outlet pipe 4. The multiple microchannels 5 create multiple micro-channels inside the U-shaped tube 2, effectively increasing the contact area with air and improving the heat exchange effect. As working time increases, dust in the air will adhere to the surface of the microchannels 5, reducing the heat exchange effect. This can be mitigated by the dual-slide linear motor 601 driving two connecting rods 602 to move closer together, thereby driving two strip plates 6... 03. When the two strip-shaped openings 10 are brought closer together, the two connecting rods 602 and the two strip-shaped plates 603 are located below the hollow parts of the two fixed frames 805 respectively. This does not affect the up and down movement of the two fixed frames 805. The threaded rod 803 can be rotated by the motor 802, which in turn drives the two fixed frames 805 and the two perforated plates 806 to descend. The descent of the two perforated plates 806 can scrape off the dust on the surfaces of the two ends of the multiple micro-tubes 5, which will eventually fall and accumulate at the bottom of the U-shaped tube 2. The arc-shaped plate 902 can be lowered by the electric push rod 901 to open the arc-shaped opening 11, making it easy to clean the dust.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
