Technical Field

[0001] The present invention particularly relates to a space-saving refrigerator evaporator. Background Art

[0002] The evaporator in the refrigerator is a key component of the refrigeration system. Its main function is to absorb internal heat, thereby lowering the temperature inside the refrigerator. Traditional refrigerator evaporators are generally composed of fins and heat dissipation copper tubes. During processing, multiple heat dissipation copper tubes need to be manually inserted into the fins one by one.

[0003] The existing refrigerator evaporator has a relatively complex structure and a large fin volume. The evaporator after manufacture is generally large in volume. When used inside a small refrigerator, it requires a large installation space, which is not conducive to the development of refrigerators to be smaller. In addition, the evaporator is not convenient for multiple combinations to be used, which affects the heat exchange area. For this reason, we propose a space-saving refrigerator evaporator.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

[0031] See also Figure 1-Figure 7 The present invention provides a technical solution: a space-saving refrigerator evaporator, comprising:

[0032] The evaporation pipe 1 includes a first cavity 3 and a second cavity 4 inside the evaporation pipe 1. A first baffle is provided between the first cavity 3 and the second cavity 4 to separate the internal spaces of the first cavity 3 and the second cavity 4, so as to facilitate the back and forth flow of the refrigerant.

[0033] At least two fins 2 are respectively provided on the upper surface and the lower surface of the evaporation pipe 1 to increase the heat dissipation area;

[0034] The first guide block 5 is fixed to one end of the evaporation pipe 1 to connect the second cavity 4 with the inner end of the first cavity 3, so that the refrigerant can flow back to the liquid inlet block 6 after exchanging heat with the outside and flow out to the outside through the liquid outlet pipe 7;

[0035] The liquid inlet block 6 is fixed to the other end of the evaporation pipe 1, and one end of the liquid inlet block 6 includes a liquid inlet pipe 8 and a liquid outlet pipe 7. The liquid inlet pipe 8 and the liquid outlet pipe 7 are arranged side by side, and the liquid inlet pipe 8 is connected to the interior of the second cavity 4, so that the refrigerant flows from the liquid inlet pipe 8 into the second cavity 4, completes the heat exchange with the outside inside the evaporation pipe 1, and then flows out from the liquid outlet pipe 7 to the outside through the first cavity 3;

[0036] A first connection hole 601 is provided on the lower surface of the liquid inlet block 6 , and a sealing block 9 or a pipe assembly connected to another evaporation pipe 1 is provided inside the first connection hole 601 , so as to facilitate the use of one or more evaporation pipes 1 .

[0037] Preferably, the pipeline assembly includes a support rod 10, a liquid guide tube 11 and a second guide block 12. The liquid guide tube 11 is provided on the inner side of the first connecting hole 601. One end of the outer surface of the liquid guide tube 11 has a threaded block 111 that is threadedly matched with the first connecting hole 601. Three evaporation pipes 1 are arranged side by side. The other end of the liquid guide tube 11 is detachably connected to a second guide block 12 that is matched with another evaporation pipe 1, and the third evaporation pipe 1 is internally connected to the second guide block 12 through another liquid inlet block 6 and another liquid guide tube 11. The support rod 10 is provided on the lower surface of the first guide block 5 to be connected and fixed with another first guide block 5, which is convenient for assembling multiple evaporation pipes 1 so that the refrigerant flows from the inside of multiple evaporation pipes 1 in turn, thereby increasing the heat exchange area with the outside.

[0038] Preferably, thread grooves 101 are provided at both ends of the support rod 10, and a thread column 501 threadably matched with the thread grooves 101 is provided on the side surface of the first guide block 5 to facilitate connection and fixation.

[0039] Preferably, a second connecting hole 121 is opened on the side wall of the second guide block 12, and the liquid guide tube 11 and the second guide block 12 are threadedly matched through the threaded block 111 and the second connecting hole 121, so as to facilitate the diversion of the refrigerant to the first cavity 3 or the second cavity 4 inside different evaporation pipes 1.

[0040] Preferably, a sealing strip 112 is embedded on the catheter 11 to improve the sealing effect of the connection.

[0041] Preferably, a second baffle 122 is fixed on the inner side of the second guide block 12 to separate the internal space thereof, so as to facilitate the guidance of the refrigerant.

[0042] Preferably, the sealing block 9 is cylindrical, and the sealing block 9 is matched with the first connecting hole 601 through a threaded portion, which facilitates the installation of the sealing block 9.

[0043] Preferably, the inner side of the liquid inlet block 6 has a third baffle that divides its internal space, and the liquid inlet pipe 8 and the liquid outlet pipe 7 are symmetrically arranged on both sides of the third baffle, so as to facilitate the refrigerant to flow inside the first cavity 3 or the second cavity 4 respectively.

[0044] Preferably, the first guide block 5 and the evaporation pipe 1 are fixed by welding to facilitate connection and fixation.

[0045] Preferably, the fins 2 are wavy in shape to facilitate a better heat exchange area.

[0046] The working principle and usage process of the present invention are as follows: When in use, the refrigerant flows into the inside of the second cavity 4 through the liquid inlet pipe 8, and then is guided by the first guide block 5 to flow into the inside of the first cavity 3. The refrigerant completes heat exchange with the outside through the fins 2 on the outer surface of the evaporation pipe 1, and then flows out to the outside through the liquid outlet pipe 7. The structure is simple and the volume is compact, which reduces the area occupied inside the refrigerator. When a longer heat exchange channel is required, the sealing block 9 can be unscrewed from the inside of the first connecting hole 601, and then one end of the liquid guide pipe 11 is matched with the first connecting hole 601. Then, a second guide block 12 that matches the liquid guide pipe 11 is fixed to one end of another evaporation pipe 1. The third evaporation pipe 1 is connected to the second guide block 12 through the liquid inlet block 6 and the liquid guide pipe 11. At this time, the refrigerant can pass through the inside of the three evaporation pipes 1 in sequence, thereby improving the heat exchange effect between the refrigerant and the outside. The same end of the three evaporation pipes 1 is connected and supported by the support rod 10 and the first guide block 5, which is convenient for ensuring that the spacing between the three evaporation pipes 1 is the same and ensuring stability after the combined connection.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
