detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is described in detail:

Referring to Fig. 3 and Fig. 4, one embodiment of the refrigerant frost water drainage device 2 of the present utility model includes a first pipe body 21 integrally formed by aluminum extrusion, and six pipe bodies 21 made of the first pipe body 21 respectively. Two cooling fins 22 extending downwards on opposite sides, two connecting pieces 23 extending downwards from the first pipe body 21 spaced apart from each other, and a fixing piece 24 extending upwards from the top end of the first pipe body 21 , a second tube body 25 connected to the connecting piece 23 , and two liquid holding fins 26 extending upwardly from two opposite sides of the second tube body 25 and located below the cooling fins 22 .

The first tube body 21 surrounds a first channel 211 extending along a first axis A. As shown in FIG. The cooling fins 22 are symmetrically arranged on two opposite sides of the first tube body 21 , so that there are three cooling fins 22 on each side. The inclination angles and lengths of these cooling fins 22 can vary according to requirements, and can also be other numbers. The connecting pieces 23 are arranged at intervals along a second axis B perpendicular to the first axis A, and in this embodiment, each connecting piece 23 is in the shape of a sheet. However, as long as the first pipe body 21 and the second pipe body 25 can be integrally connected, these connecting pieces 23 can of course be in other shapes as required. The fixing member 24 can be installed on the wall of a freezer (not shown) or other equipment with screws or other fixing members 24 to fix the first pipe body 21 . The second tube body 25 extends in the same direction as the first tube body 21 and surrounds a second channel 251 extending along the first axis A. As shown in FIG.

Referring to Fig. 4 and Fig. 5, the ends of the projected ranges C and D of each cooling fin 22 projected on the second axis B are always located in the projected range of the corresponding liquid holding plate 26 projected on the second axis B In E, therefore, the frost water dripping from these cooling guide sheets 22 will all fall on these liquid holding sheets 26, thereby avoiding the situation that the frost water drips on the ground and causes dirt. It should be noted that the second pipe body 25 can also be arranged slightly inclined relative to the first pipe body 21 , so that the frost water received by the liquid holding sheets 26 can flow downward for easy collection.

Referring to Fig. 3, Fig. 4 and Fig. 6, the present embodiment is applied in a refrigeration system 3. In this refrigeration system 3, a plurality of refrigerant frost water drainage devices 2 are spaced and arranged side by side, and coil pipes 30 are used to penetrate The first flow channel 211 and the second flow channel 251 of the refrigerant frost water drainage device 2 . When the refrigeration system 3 is in operation, the antifreeze liquid flowing through the coil 30 of the first channel 211 can absorb heat energy in the surrounding environment to produce a cooling effect. The antifreeze in the first channel 211 will then flow into a compressor 31 to be compressed and heated up, and the antifreeze after heating again will flow into a heat energy recovery device 32 for heat exchange with water to dissipate heat, and finally the antifreeze will be Send to a radiator 33 to further reduce the temperature, and return the low-temperature antifreeze to the coil 30 to carry out the refrigeration cycle again. It should be noted that the coiled pipe (not shown) in the second flow channel 251 can be used for high-temperature antifreeze to pass through, so that the frost water received by these liquid-holding sheets 26 can be kept in a liquid state by using its high temperature, so that it can Avoid the problem that frost water freezes and is not easy to collect.

To sum up, the liquid holding sheets 26 can receive the frost water dripped from the cooling guide sheets 22 and guide it to the target place for collection, so as to prevent the frost water from dripping on the ground and causing dirt. The second pipe body 25 can circulate high-temperature antifreezing liquid to transfer heat energy to the liquid-holding sheets 26, so that the frost water can maintain a liquid state due to the temperature rise to facilitate flow. The first pipe body 21, the cooling fins 22, the connectors 23, the second pipe body 25 and the liquid holding sheets 26 are integrally formed by aluminum extrusion, so the structural strength is high and no additional assembly is required. There will be no looseness between components to avoid noise generation, so the purpose of the utility model can be really achieved.
