Detailed Implementation

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] Currently, air-cooled refrigerators are the mainstream product on the market, and they mainly use finned evaporators. These evaporators have a large cooling capacity per unit area, providing sufficient cooling for large-capacity refrigerators. However, some refrigerant vaporizes after being throttled through the capillary tube. This vaporized refrigerant occupies some space within the finned evaporator's pipes, but its cooling effect is far less than that of liquid refrigerant, resulting in a decrease in the finned evaporator's cooling efficiency. Furthermore, the vaporized refrigerant occupying space within the finned evaporator leads to inaccurate refrigerant charge amounts in low-temperature tests. Therefore, this invention provides the following embodiments to solve the above problems.

[0029] Example 1:

[0030] like Figures 1-4 As shown. The novel finned evaporator includes: an evaporation tube 1, which includes an inlet pipe 101 and an outlet pipe 102; and a gas-liquid separator 2, which includes a gas-liquid separation tank 201 and a gas-liquid separation pipe 202. The gas-liquid separation pipe 202 is disposed inside the gas-liquid separation tank 201, and the bottom of the gas-liquid separation tank 201 is connected to and communicates with the inlet pipe 101. The outlet pipe 102 penetrates through the top side of the gas-liquid separation tank 201. The gas-liquid separation pipe 202 is connected to the bottom of the gas-liquid separation pipe 202.

The return pipe 3 has one end that passes through the side wall of the gas-liquid separation tank 201 and extends into the gas-liquid separation tank 201.

[0031] like Figures 1-3As shown, in the present embodiment, the new finned evaporator comprises an evaporating pipe 1, a gas-liquid separator 2 and a liquid return pipe 3, wherein the evaporating pipe 1 comprises a liquid inlet pipe 101 and a liquid outlet pipe 102, the liquid inlet pipe 101 is located below the liquid outlet pipe 102, the gas-liquid separator 2 comprises a gas-liquid separation tank 201 and a gas-liquid separation pipe 202, the gas-liquid separation pipe 202 is arranged in the gas-liquid separation tank 201, the bottom of the gas-liquid separation tank 201 is connected and communicated with the right end of the liquid inlet pipe 101, the left end of the liquid outlet pipe 102 penetrates through the top side wall of the gas-liquid separation tank 201 and is connected with the bottom end of the gas-liquid separation pipe 202, the gas-liquid separation pipe 202 is provided with a liquid outlet hole 2021 and a gas return hole 2022, the liquid outlet hole 2021 is arranged on the bottom side of the gas-liquid separation pipe 202, and the gas return hole 2022 is arranged on the top side or side of the gas-liquid separation pipe 202, so as to separate the liquid refrigerant and the gaseous refrigerant, and the liquid outlet hole 2021 and the gas return hole 2022 are both located in the gas-liquid separation tank 201, the top end of the gas-liquid separation pipe 202 penetrates and extends out of the gas-liquid separation tank 201, and the left end of the liquid return pipe 3 penetrates through the side wall of the gas-liquid separation tank 201 and extends into the gas-liquid separation tank 201. Specifically, in the present embodiment, the liquid refrigerant and the mixed gaseous refrigerant in the capillary pipe of the refrigerator will flow into the gas-liquid separation tank 201 through the liquid return pipe 3, the liquid return pipe 3 is a capillary transition pipe, at this time the liquid refrigerant further flows into the liquid inlet pipe 101 under the action of its own gravity, and most of the gaseous refrigerant in the gas-liquid separation tank 201 flows upward under the action of the suction force of the compressor in the refrigerator and flows into the gas-liquid separation pipe 202 through the gas return hole 2022, avoiding a large amount of gaseous refrigerant occupying the internal space of the evaporating pipe 1, thereby improving the refrigeration effect of the new finned evaporator, the liquid refrigerant flows into the evaporating pipe 1 from the liquid inlet pipe 101 and then flows out from the liquid outlet pipe 102, at this time the liquid refrigerant in the liquid outlet pipe 102 may still be mixed with a small amount of gaseous refrigerant, when the liquid refrigerant and the small amount of gaseous refrigerant flow to the liquid outlet hole 2021 of the gas-liquid separation pipe 202, the liquid refrigerant will fall from the liquid outlet hole 2021 to the bottom of the gas-liquid separation tank 201 under the action of gravity and return to the liquid inlet pipe 101, a small amount of gaseous refrigerant will continue to flow along the gas-liquid separation pipe 202 under the action of the suction force of the compressor and combine with most of the gaseous refrigerant, and then be discharged to the circulating refrigeration assembly in the refrigerator through the gas-liquid separation pipe 202 to re-condense into liquid refrigerant, keeping the total amount of refrigerant unchanged to maintain the refrigeration effect of the new finned evaporator.

[0032] As Figure 4As shown, as a further scheme, the gas-liquid separator 2 further comprises a partition plate 203 horizontally arranged in the gas-liquid separation tank 201, the side periphery of the partition plate 203 is connected and sealed with the inner side wall of the gas-liquid separation tank 201, and the partition plate 203 is provided with a through hole 2031. Specifically, after the partition plate 203 is arranged in the gas-liquid separation tank 201, the liquid refrigerant falling from the liquid outlet hole 2021 can only flow to the bottom of the gas-liquid separation tank 201 and the liquid inlet pipe 101 through the through hole 2031. Compared with before the partition plate 203 is installed, the liquid refrigerant flowing out of the liquid outlet hole 2021 can be evenly flowed into the liquid inlet pipe 101 after the partition plate 203 is installed. At the same time, in this embodiment, after the left end of the liquid return pipe 3 extends into the gas-liquid separation tank 201, the left end of the liquid return pipe 3 is located above the gas-liquid separation tank 201, so that the flow of liquid refrigerant flowing from the gas-liquid separation tank 201 to the liquid inlet pipe 101 is uniform.

[0033] As a further scheme, along the direction from the side edge of the partition plate 203 to the center of the partition plate 203, the side periphery of the partition plate 203 is recessed towards the center, and the through hole 2031 is arranged at the center. Specifically, the partition plate 203 can be recessed towards the center in an umbrella shape, so as to converge the liquid refrigerant falling from the liquid outlet hole 2021 to fall from the through hole 2031, and avoid the liquid refrigerant remaining on the top side of the partition plate 203; at the same time, after the left end of the liquid return pipe 3 extends into the gas-liquid separation tank 201, if the left end of the liquid return pipe 3 is located below the gas-liquid separation tank 201, the side edge of the partition plate 203 is also provided with a gas permeable hole (not shown), so that the gaseous refrigerant below the partition plate 203 can flow to the gas return hole 2022 and the gas-liquid separation pipe 202 above the partition plate 203.

[0034] In this embodiment, the bottom of the gas-liquid separation tank 201 is funnel-shaped, and the bottom tip of the gas-liquid separation tank 201 is connected and communicated with the liquid inlet pipe 101. Specifically, the gas-liquid separation tank 201 is cylindrical, and the bottom of the gas-liquid separation tank 201 is funnel-shaped, so as to converge the liquid refrigerant falling from the through hole 2031 at the tip of the bottom of the gas-liquid separation tank 201, and then flow into the liquid inlet pipe 101, avoiding the liquid refrigerant remaining in the gas-liquid separation tank 201 to cause insufficient refrigeration effect of the evaporating pipe 1, so as to further improve the refrigeration effect of the evaporating pipe 1.

[0035] As a further scheme, the gas-liquid separation tank 201 is made of aluminum or copper skin. The aluminum or copper skin has good cold insulation effect and relatively low cost, and is resistant to oxidation and corrosion, has long service life, and has high cost performance.

[0036] As a further solution, the new finned evaporator further comprises a gas outlet pipe 4, the top end of the gas-liquid separation pipe 202 is arranged in the gas-liquid separation tank 201, one end of the gas outlet pipe 4 penetrates through the side wall of the gas-liquid separation tank 201 and extends into the gas-liquid separation tank 201 to be connected with and communicated with the top end of the gas-liquid separation pipe 202. Specifically, in this embodiment, the gas-liquid separation pipe 202 is completely located in the gas-liquid separation tank 201, the gas outlet pipe 4 is a gas outlet transition pipe, the left end of the gas outlet pipe 4 penetrates through the top side of the gas-liquid separation tank 201 and extends into the gas-liquid separation tank 201 to be connected with and communicated with the top end of the gas-liquid separation pipe 202, so as to assist the gaseous refrigerant to flow out of the gas-liquid separation tank 201.

[0037] In this embodiment, the liquid outlet pipe 102 and the gas outlet pipe 4 are respectively detachably connected with the gas-liquid separation pipe 202. Specifically, a threaded sleeve (not shown) is arranged between the liquid outlet pipe 102 and the gas-liquid separation pipe 202 and between the gas outlet pipe 4 and the gas-liquid separation pipe 202, the threaded sleeve is tubular and has internal threads in the ports at both ends, the outer sides of the ends of the gas-liquid separation pipe 202 are respectively provided with external threads, the outer sides of the right end of the liquid outlet pipe 102 and the left end of the gas outlet pipe 4 are respectively provided with external threads, and the two ends of one threaded sleeve are respectively sleeved on the right end of the liquid outlet pipe 102 and the left end of the gas-liquid separation pipe 202 and are threadedly connected, and the two ends of the other threaded sleeve are respectively sleeved on the right end of the gas-liquid separation pipe 202 and the left end of the gas return pipe and are threadedly connected. By detachably connecting the liquid outlet pipe 102 and the gas outlet pipe 4 with the gas-liquid separation pipe 202, the gas-liquid separation pipe 202 can be easily disassembled for replacement or maintenance in the later period.

[0038] As a further solution, the other end of the liquid return pipe 3 and the other end of the gas outlet pipe 4 are respectively connected with the circulating refrigeration assembly in the refrigerator to form a circulating refrigeration circuit. Specifically, the circulating refrigeration assembly comprises refrigerator accessories such as a compressor, a condenser and a capillary tube, and the circulating refrigeration assembly is an assembly in the existing refrigerator. By connecting the other end of the liquid return pipe 3 and the other end of the gas outlet pipe 4 with the circulating refrigeration assembly in the refrigerator to form a circulating refrigeration circuit, the gaseous refrigerant separated from the liquid refrigerant can be recycled and utilized, thereby avoiding the decrease of the total amount of refrigerant to cause the refrigeration effect to be poor, and the gaseous refrigerant is adiabatically compressed into high-temperature and high-pressure gaseous refrigerant by the compressor, then is cooled into liquid refrigerant by the condenser, and then is throttled into the liquid return pipe 3 by the capillary tube, and finally flows into the gas-liquid separation tank 201 and the evaporation pipe 1, so that the total amount of refrigerant is kept unchanged to maintain the refrigeration effect of the new finned evaporator.

[0039] As a further solution, the liquid outlet holes 2021 are provided in multiple numbers and arranged in rows along the flow direction of the refrigerant on the gas-liquid separation pipe 202. By providing multiple liquid outlet holes 2021 on the gas-liquid separation pipe 202, the return flow of the liquid refrigerant can be accelerated, and most of the liquid refrigerant can fall into the gas-liquid separation tank 201 through the multiple liquid outlet holes 2021. The liquid outlet holes 2021 can also be provided in multiple rows, and the multiple rows of liquid outlet holes 2021 are arranged along the length direction of the gas-liquid separation pipe 202. Alternatively, the liquid outlet holes 2021 can also be provided around the circumference of the gas-liquid separation pipe 202, and the multiple liquid outlet holes 2021 form a ring. Multiple rings of liquid outlet holes 2021 are provided on the gas-liquid separation pipe 202, further accelerating the flow of the liquid refrigerant into the gas-liquid separation tank 201.

[0040] The novel finned evaporator provided by the application has the following advantages:

[0041] The liquid refrigerant and the gaseous refrigerant can be separated by the combination of the gas-liquid separator 2, the gas return pipe 3 and the gas outlet pipe 4 to provide the refrigeration effect of the evaporating pipe 1.

[0042] By providing the baffle 203 in the gas-liquid separation tank 201, the liquid refrigerant can flow uniformly into the liquid inlet pipe 101.

[0043] The baffle 203 is recessed towards the center and the bottom of the gas-liquid separation tank 201 is funnel-shaped, which can avoid the liquid refrigerant remaining in the gas-liquid separation tank 201, thereby ensuring the sufficient amount of liquid refrigerant in the evaporating pipe and improving the refrigeration effect of the evaporating pipe.

[0044] By connecting the other end of the liquid return pipe 3 and the other end of the gas outlet pipe 4 to the circulating refrigeration assembly in the refrigerator to form a circulating refrigeration loop, the gaseous refrigerant can be re-condensed into liquid refrigerant, the total amount of refrigerant remains unchanged to maintain the refrigeration effect of the novel finned evaporator.

The liquid refrigerant flows into the evaporation pipe 1 from the liquid inlet pipe 101 and then flows out from the liquid outlet pipe 102, at this time, the liquid refrigerant in the liquid outlet pipe 102 may still be mixed with a small amount of gaseous refrigerant, when the liquid refrigerant and the small amount of gaseous refrigerant flow to the liquid outlet hole 2021 of the gas-liquid separation pipe 202, the liquid refrigerant will fall to the bottom of the gas-liquid separation tank 201 and return to the liquid inlet pipe 101 under the action of gravity, and the small amount of gaseous refrigerant will continue to flow along the gas-liquid separation pipe 202 under the action of the suction force of the compressor and be combined with most of the gaseous refrigerant, and then be discharged to the circulating refrigeration assembly in the refrigerator through the gas-liquid separation pipe 202 to re-condense into liquid refrigerant, keeping the total amount of refrigerant unchanged to maintain the refrigeration effect of the new finned evaporator.
