Description

Technical Field

[0001] The invention particularly relates to a novel detachable refrigerator evaporator. Background Art

[0002] The refrigerator evaporator is an important component in the refrigeration system. It is connected to other components such as the compressor and condenser through pipes to form a complete refrigeration cycle. The evaporator is responsible for absorbing heat from the inside of the refrigerator to maintain low temperature. The evaporator is usually made of copper or aluminum for good thermal conductivity. The traditional refrigerator evaporator is generally composed of fins and evaporation pipes. During processing, multiple evaporation pipes need to be manually inserted into the fins one by one, and then the multiple evaporation pipes are connected and fixed together through bending and welding, so that the refrigerant can flow in the multiple evaporation pipes to exchange heat with the outside.

[0003] The existing refrigerator evaporator has a complex structure and a large fin volume. The volume of the manufactured evaporator is generally large, which is not convenient for miniaturization production and processing. In addition, multiple evaporation pipes are connected to form a whole. It is not convenient to disassemble and maintain the individually damaged evaporation pipes in the later stage. The whole pipe can only be replaced, and the maintenance cost is high. For this reason, we propose a new detachable refrigerator evaporator. Summary of the invention

[0004] The object of the present invention is to provide a new type of detachable refrigerator evaporator 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 detachable refrigerator evaporator, comprising:

[0006] A first support member and a second support member arranged side by side therewith;

[0007] A liquid inlet pipe, disposed on a side wall of the second support member to introduce refrigerant into the inner side of the second support member;

[0008] A heat dissipation pipe connected between the second support member and the first support member through a mounting assembly to guide the coolant inside the second support member to the first support member;

[0009] A first heat dissipation fin is fixed to the upper surface of the heat dissipation pipe, and a second heat dissipation fin having the same structure as the first heat dissipation fin is provided on the lower surface of the heat dissipation pipe;

[0010] The second support member has a cavity inside, and a guide plate for guiding the coolant is fixed inside the cavity.

[0011] Preferably, the mounting assembly includes a mounting boss, a threaded groove, a protrusion, a connecting tube and a sealing rubber. A side wall of the first support member protrudes outward to form a mounting boss. The inner side of the mounting boss protrudes outward to form a connecting tube inserted into the inner side of the heat dissipation tube. The outer surface of the connecting tube is embedded with a sealing rubber in contact with the heat dissipation tube. Protrusions are fixed at both ends of the outer surface of the heat dissipation tube, and mounting bolts matching the mounting bosses are arranged on the inner side of the protrusions.

[0012] Preferably, a groove is formed on one side wall of the mounting boss, and a liquid-absorbing and swelling rubber that contacts the convex block is disposed inside the groove.

[0013] Preferably, a thread groove is provided on the inner side of the mounting boss along its circumference, and the thread groove corresponds to the mounting bolt.

[0014] Preferably, the sealing rubber is provided at two locations along the axial direction of the connecting pipe.

[0015] Preferably, a plurality of heat dissipation pipes are evenly distributed along the height direction of the first support member.

[0016] Preferably, the first heat dissipation fins are wavy in shape.

[0017] Preferably, the second support member is flush with an end of the first support member, and a liquid outlet pipe is provided on one side wall of the first support member.

[0018] Preferably, a plurality of the first heat dissipation fins and the second heat dissipation fins are arranged along the heat dissipation tube, and the height of the first heat dissipation fins is greater than the height of the heat dissipation tube.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This patent avoids the need for larger fins in traditional evaporators by providing a first support member, a second support member, a heat dissipation pipe, a first heat dissipation fin, a second heat dissipation fin and a mounting assembly. A plurality of evaporation pipes are inserted into the fins to connect the plurality of evaporation pipes to form a whole. The volume after production is relatively large, and after installation inside the refrigerator, it occupies a large space inside the refrigerator. The evaporator structure of this device is simple, and the heat dissipation fins can be processed directly by turning on both sides of the heat dissipation pipe during processing, which is beneficial to reducing the volume after processing and greatly reducing the volume occupied inside the refrigerator during installation. The operation is convenient, and the heat dissipation pipe can be disassembled and replaced conveniently in the later stage, and the maintenance is simple, thereby improving the practicality of the device.

[0031] The heat dissipation pipe 4 is connected between the second support member 2 and the first support member 1 through the mounting assembly to introduce the coolant inside the second support member 2 into the first support member 1, so as to facilitate heat dissipation and evaporation, and to guide the heat of the refrigerant to the outside;

[0032] The first heat dissipation fin 5 is fixed to the upper surface of the heat dissipation tube 4, and the lower surface of the heat dissipation tube 4 has a second heat dissipation fin 6 with the same structure as the first heat dissipation fin 5, so as to better exchange heat with the outside and improve the heat exchange effect between the refrigerant and the outside;

[0033] The second support member 2 has a cavity 8 inside, and a guide plate 7 for guiding the coolant is fixed inside the cavity 8, so as to guide the flow direction of the refrigerant and make the refrigerant flow from the inside of the plurality of heat dissipation tubes 4 in sequence.

[0034] Preferably, the mounting assembly includes a mounting boss 901, a threaded groove 9011, a protrusion 902, a connecting tube 903 and a sealing rubber 905. A side wall of the first support member 1 protrudes outward to form a mounting boss 901. The inner side of the mounting boss 901 protrudes outward to form a connecting tube 903 inserted into the inner side of the heat dissipation tube 4. The outer surface of the connecting tube 903 is embedded with a sealing rubber 905 in contact with the heat dissipation tube 4. Protrusions 902 are fixed at both ends of the outer surface of the heat dissipation tube 4. The inner side of the protrusion 902 is provided with mounting bolts that cooperate with the mounting boss 901, so as to facilitate the detachable connection between the heat dissipation tube 4 and the first support member 1, so as to facilitate the disassembly, replacement and maintenance of the heat dissipation tube 4 at a later time.

[0035] Preferably, a groove is formed on one side wall of the mounting boss 901, and a liquid-absorbing and swelling rubber 904 is disposed inside the groove to abut against the protrusion 902, so that when liquid leaks, the liquid-absorbing and swelling rubber 904 expands in volume to seal the leak, thereby improving the sealing effect.

[0036] Preferably, a thread groove 9011 is provided on the inner side of the mounting boss 901 along its circumference, and the thread groove 9011 corresponds to the mounting bolt, so as to improve the convenience of connection.

[0037] Preferably, the sealing rubber 905 is provided at two locations along the axial direction of the connecting pipe 903 to facilitate a better sealing effect on the connection.

[0038] Preferably, a plurality of heat dissipation pipes 4 are evenly distributed along the height direction of the first support member 1, so as to facilitate better heat exchange between the refrigerant and the outside.

[0042] The working principle and use process of the present invention are as follows: when in use, the connecting tube 903 at one end of the first support member 1 is inserted into the inner side of the heat dissipation tube 4, at which time the protrusion 902 contacts the mounting boss 901, and the mounting bolt is screwed into the inner side of the threaded groove 9011 to fix the heat dissipation tube 4 to the first support member 1. A good sealing effect can be achieved at the connection by means of a plurality of sealing rubbers 905, and in case of accidental leakage, the liquid-absorbing and swelling rubber 904 will absorb the liquid to expand, thereby improving the sealing effect and ensuring stable sealing. Similarly, the second support member 2 can be connected and fixed to the heat dissipation tube 4, and the refrigerant flows into the second support member 2, the heat dissipation tube 4 and the first support member 1 in turn through the liquid inlet pipe 3, and the heat is dissipated through the first heat dissipation fins 5 and the second heat dissipation fins 6 on the outer surface of the heat dissipation tube 4 to complete heat exchange with the outside.
