A filter is fixed at the end of a short U-shaped internal thread heat exchange tube 2. The filter model is 2-12.7-L100 and the manufacturer is Changzhou Taohua Electric Appliance Co., Ltd.

[0029] The condenser is composed of aluminum foil fins 1, short U-shaped internal thread heat exchange tube 2, long U-shaped internal thread heat exchange tube 3, gas collecting tube assembly 9, and liquid collecting tube assembly 10. The condenser model is MDVH-V120 / 140W, and the supplier is Haikou Longhua Yihong Department Store.

[0030] Working principle or structural principle: During refrigeration, the refrigerant medium is divided into several paths after entering the condenser through the liquid inlet port of the gas collecting pipe assembly 9. These paths enter the condenser through the short U-shaped internal thread heat exchange tubes 2 for heat exchange. After heat exchange, the refrigerant medium from these paths converges and enters the liquid collecting pipe assembly 10. The liquid refrigerant condensed from the liquid collecting pipe assembly 10 enters the bottom two short U-shaped internal thread heat exchange tubes 2 of the condenser through the Y-shaped tee port for subcooling heat exchange, i.e., subcooling. The subcooled low-temperature liquid refrigerant from the bottom of the condenser flows out through the other port of the condenser and then out through one end of the filter. During heating, the low-temperature liquid refrigerant passes through the filter... After passing through the Y-type filter, the refrigerant from the bottom of the condenser enters the short U-shaped internal thread heat exchange tube 2 at the bottom of the condenser for pre-evaporation and heat absorption. Due to the large flow rate and velocity of the liquid refrigerant in the short U-shaped internal thread heat exchange tube 2, the bottom of the condenser is not solid and does not freeze. The multiple pre-evaporated refrigerants from the bottom of the condenser enter the liquid collection tube assembly 10 through the Y-type filter. The refrigerant in the liquid collection tube assembly 10 is divided into several streams and enters several long U-shaped internal thread heat exchange tubes 3 in the condenser for heat exchange. After absorbing heat and evaporating, the several streams of refrigerant converge and enter the gas collection tube assembly 9, and then flow out through its port.

[0031] If the condenser needs to be disassembled, the operator can pull the clamping plate 802, which will cause the sliding plate 702 and the insert rod 701 to move, thereby disengaging the insert rod 701 from the horizontal plate 4. The clamping plate 802 can be rotated to position it between the limiting plates, thereby locking the sliding plate 702. After locking the other sliding plate 702 in accordance with the law, the horizontal plate 4, along with the condenser on its surface, can be separated from the outer casing 5, achieving the purpose of rapid disassembly.

[0032] In summary, this device has advantages such as quick disassembly and replacement and low risk of leakage.
