Description

Technical Field

[0001] The present invention particularly relates to a novel refrigerator evaporator which saves space. 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 complex structure and a large fin volume. The evaporator after manufacture is generally large in volume. When used inside a small refrigerator, a large installation space is required, which is not conducive to the development of refrigerators to be smaller. In addition, the evaporator is not convenient for multiple combinations, which affects the heat exchange area. For this reason, we propose a new space-saving refrigerator evaporator. Summary of the invention

[0004] The object of the present invention is to provide a new type of refrigerator evaporator which saves space, so as to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a new type of refrigerator evaporator that saves space, comprising:

[0012] Preferably, thread grooves are formed at both ends of the support rod, and a side surface of the first guide block has a thread column that is threadably matched with the thread grooves.

[0013] Preferably, a second connecting hole is formed on the side wall of the second guide block, and the liquid guiding tube and the second guide block are threadedly matched via the threaded block and the second connecting hole.

[0014] Preferably, a sealing strip is embedded on the liquid guiding tube.

The evaporator of the device has a simple structure, and the double-sided fin design has a better heat exchange area, which is conducive to miniaturization processing and reduces the volume occupied inside the refrigerator during installation. Multiple evaporation pipes can be combined in the later stage, which increases the heat exchange length and area of ​​the device and ensures a good thermal conductivity effect.

[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 arranged 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 arranged on the lower surface of the first guide block 5 to be connected and fixed to 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 sequence, 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 the side surface of the first guide block 5 has a thread column 501 threadably matched with the thread groove 101, so as 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 refrigerant to be guided 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 liquid guiding tube 11 to improve the sealing effect of the connection.

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

[0046] The working principle and use process of the present invention are as follows: when in use, the refrigerant flows into the inner side of the second cavity 4 through the liquid inlet pipe 8, and then flows into the inner side of the first cavity 3 through the first guide block 5. 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 from the liquid outlet pipe 7. The structure is simple and the volume is compact, which reduces the area occupied on the inner side of the refrigerator. When a longer heat exchange channel is required, the sealing block 9 can be screwed out from the inner side of the first connecting hole 601, and then one end of the liquid guide pipe 11 is matched with the first connecting hole 601, and then another evaporation pipe 1 is fixed with a second guide block 12 matched with the liquid guide pipe 11 at one end, and 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 inner side of the three evaporation pipes 1 in sequence, which improves 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 intervals between the three evaporation pipes 1 are the same, and ensuring the stability after the combined connection.
