Problems solved by technology

When the evaporator is working, the airflow flows from one end to the other through the gap between the fins, but the air flow between the fins is not smooth, the temperature is uneven, and the heat transfer efficiency is low, which results in a slow cooling speed of the refrigerator.

Embodiment 2

[0009] Embodiment two see image 3 As shown, there are airflow holes around the lower piercing hole 5 arranged under the fin 2, and the upper piercing hole 4 set on the fin is surrounded by a smooth metal surface, that is to say: there is no surrounding area of ​​the upper piercing hole. Airflow holes.

Embodiment 3

[0010] Embodiment three, see Figure 4 As shown, there are airflow holes 3 evenly distributed around the upper and lower piercing holes of the fins 2 corresponding to the upper and lower sides.

[0011] For the schematic diagram of the above-mentioned fin installation structure, please refer to Figure 5 As shown, there are evaporating tubes in the upper and lower holes of the fins, such as Figure 5 As shown, the fins can be assembled in multiple pieces, and the airflow holes on each fin can be rotated by 180° during assembly. see also Figure 6 Shown, each fin can be according to actual needs according to Figure 6 As shown, they are arranged and installed in sequence. The airflow holes on the assembled fin evaporator are interconnected to form gas convection channels, which accelerates the convection between the air between the fins, thereby improving the cooling effect.

Abstract

The invention discloses an air cooling finned evaporator which comprises fins, wherein tube penetrating holes are formed in the upper positions and the lower positions of the fins correspondingly, airflow holes are formed around the tube penetrating holes, and the tube penetrating holes are geometrical. According to the air cooling finned evaporator, the airflow holes are formed in the fins to quicken air convection among the fins. The air cooling finned evaporator has the effects that the airflow holes formed in the fin quicken air convection among the fins, temperature is more uniform, the heat transfer efficiency is improved, refrigerating is fastened, and the refrigerating effect is improved.

Description

Technical field: [0001] The invention relates to an air-cooled fin evaporator, which is especially suitable for use in the refrigeration field of household appliances. Background technique: [0002] Air-cooled finned evaporator, the fins are arranged on the tubes, and the cooling air circulates through the fin gaps for heat exchange when the evaporator is refrigerated. At present, the fins used in finned evaporators are mostly made of metal sheets. The metal sheets are perforated and piped, and the refrigerant flows in the pipes. The holes on the fins are only used for piercing pipes or heating wires, and there are no holes in other positions. This kind of fin structure leads to poor air convection between different rows of fins when the air is circulating, uneven temperature, and low heat transfer efficiency, which in turn leads to slow cooling speed, poor cooling capacity and high energy consumption of the refrigerator. . Existing finned evaporators have no holes on ...
