Description

Technical Field

[0001] This utility model belongs to the technical field of finned evaporators, specifically relating to a refrigerator finned evaporator that prevents icing. Background Technology

[0002] The finned evaporator is a core component of the refrigerator's refrigeration system, and its performance directly affects the refrigerator's refrigeration efficiency, energy consumption, and service life.

[0003] A search revealed that application number CN201922254911.8 discloses a finned evaporator for a refrigerator, including components such as coils, supports, and fins. It reduces pipe density by using an isosceles trapezoidal staggered pipe arrangement; it forms fin groups from several fins and improves the finning coefficient by setting air vents on the fins; and it achieves the goals of saving materials, reducing component manufacturing costs, and improving the refrigerator's energy efficiency and operational reliability while maintaining the overall heat exchange area and efficiency of the evaporator.

[0004] However, there are still some shortcomings. For example, when the coil is in use, air and circulating liquid enter the coil. Dust, hair, fibers, iron filings and other impurities contained in the air and circulating liquid will also enter the inside of the coil. The accumulation of impurities will cause scale to form on the surface of the coil, block the gaps, and even puncture the coil (such as iron filings), causing refrigerant leakage and other phenomena.

[0011] As a further improvement of this utility model: a guide rod is slidably connected inside the movable frame, the guide rod completely penetrates the movable frame, and the guide rod is fixedly installed on the front side of the finned evaporator body by a fixing block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1.

[0023] like Figure 1 and Figure 2 As shown, the filtration mechanism 5 includes an installation pipe 8 located between the inlet pipe 3 and the connecting pipe 6. A filter screen 9 is fixedly connected to the inner wall of the installation pipe 8. A first sealing pipe 10 is fixedly connected to one end of the installation pipe 8, and a second sealing pipe 11 is fixedly connected to the other end of the installation pipe 8. Sealing grooves 13 are formed inside the inlet pipe 3 and the connecting pipe 6. Connecting screws 14 are installed through the interior of both the inlet pipe 3 and the connecting pipe 6, with the ends of the connecting screws 14 extending into the interior of the sealing grooves 13. Connecting screw holes 12 that match the connecting screws 14 are formed inside the first sealing pipe 10 and the second sealing pipe 11.

[0024] Working principle and usage process of this utility model:

[0025] In use, the first sealing tubes 10 at both ends of the installation tube 8 are inserted into the sealing grooves 13 inside the liquid inlet tube 3 and the connecting tube 6 respectively to achieve a preliminary sealing connection. Then, the connecting screws 14 are inserted into the connecting screw holes 12 to lock the liquid inlet tube 3 and the connecting tube 6 to both ends of the installation tube 8. The liquid inlet tube 3 and the connecting tube 6 are installed together. The air and circulating liquid introduced by the connecting tube 6 will be filtered by the filter screen 9.
