Background

The existing air conditioners are various in types and have strong competition, and cost reduction and energy improvement become more important in the field of air conditioners. The heat exchange principle of the air conditioner is mainly realized by driving the whole pipeline system by a compressor, enabling an evaporator at the indoor side of the air conditioner to absorb heat, enabling the evaporator at the outdoor side of the air conditioner to release heat and the like.

However, the traditional air-conditioning condenser is composed of radiating pipes, fins, sheet metal side plates and the like, and is generally in a regular shape, such as a rectangle, L shape, U shape and the like.

The heat exchange fan blades outside the air conditioner chamber generally adopt axial flow fan blades, the wind field generated by the axial flow fan blades is smaller in the middle part, the air quantity is very low, the wind field around the outer ring of the fan blades is larger, and the air quantity is higher, namely, the axial flow fan generates a wind field blind area in the middle part. Therefore, the air quantity blown onto the condenser fins is basically consistent with the size of the wind field generated by the fan blades, so that the heat exchange efficiency of the condenser fins opposite to the middle parts of the axial flow fan blades is low, and the heat exchange efficiency of the condenser fins opposite to the peripheral parts of the axial flow fan blades is high, thereby reducing the overall heat exchange efficiency of the condenser.

Detailed Description

In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.

As shown in fig. 1, the refrigerating apparatus of the present invention includes a condenser and an axial flow fan 5. The airflow of the axial flow fan 5 blows to the condenser fins 2 to take away the heat of the condenser, and the heat exchange effect is achieved.

The condenser includes a radiating pipe 1, fins 2 and side plates 3. The fins 2 arranged layer by layer are arrayed between the two side plates 3. The heat radiating pipe 1, which is generally a copper pipe, is repeatedly passed through the side plate 3 and the fin 2 in a meandering manner.

In order to solve the influence brought by the wind field blind area of the axial flow fan 5, the fins 2 are provided with the resistance reducing parts 4 in the wind field blind area, and the resistance of the fins 2 of the resistance reducing parts 4 for the air flow passing through the fins 2 of other parts is lower, so that low-speed air in the wind field blind area can conveniently pass through the fins 2, and the heat exchange efficiency of the condenser is improved.

In order to reduce the resistance of the resistance reducing portion 4, the following different schemes may be adopted.

Example 1: as shown in fig. 2, the width of the fin 2 of the fairings 4 is smaller than the width of the fins 2 of the other portions. The width of the fins 2 of the resistance reducing part 4 can be controlled between 22 mm and 26mm, and the optimal heat dissipation effect is 24 mm. Therefore, the low-speed airflow in the wind field blind area has shorter stroke and lower resistance.

Example 2: as shown in fig. 3, the radiating pipe 1 is disposed around the resistance reducing part 4. Specifically, the radiator pipe 1 includes straight pipe portions 11 located at upper and lower sides of the resistance reducing portion 4, and bent pipe portions 12 located at left and right sides of the resistance reducing portion 4, and one ends of the bent pipe portions 12 near the resistance reducing portion 4 are connected in series to the adjacent straight pipe portions 11. Thus, the air duct complexity of the drag reduction part 4 is reduced, and the resistance is lower.

And in order to further reduce the resistance, the two schemes can be used simultaneously.

Besides the above two schemes, other schemes can be adopted, such as that the spacing between adjacent fins 2 of the drag reducing part 4 is larger than that between adjacent fins 2 of other parts. The distance between the adjacent fins 2 of the resistance reducing part 4 can be controlled between 1.2mm and 1.6mm, and the optimal heat dissipation effect is 1.2 mm.
