Example Embodiment

[0024] Such as Figure 1-4 As shown, the present invention provides a heat exchange fin group, which includes:

[0025] The first row of fins 1 and the second row of fins 2, the first row of fins 1 and the second row of fins 2 are arranged in sequence along the airflow direction, and the second row of fins 2 are arranged on the The first row of fins 1 is provided with at least one first pipe hole 11 through which the heat exchange tube passes along the airflow direction, and the second row of fins 2 is provided with There is at least one second tube hole 21 that can accommodate the heat exchange tube. The second tube hole 21 is opposite to the position between the two adjacent first tube holes 11 along the direction of air flow, and extends along The structure between the first row of fins 1 and the second row of fins 2 that is opposite to the first tube hole 11 in the direction of airflow is a structure with a gap 3 (the gap here is disconnected) The structure includes a struc...

Abstract

The invention provides a heat exchanging fin group, a heat exchanger and an air conditioner. The heat exchanging fin group comprises a first row of fins and a second row of fins; the first row of finsand the second row of fins are sequentially arranged in the airflow flow direction; first pipe holes are formed in the first row of fins; second pipe holes are formed in the second row of fins; in the airflow flow direction, the second pipe holes and the two adjacent first pipe holes are opposite in position; structures in the airflow flow direction, opposite to the first pipe holes and between the first row of fins and the second row of fins are disconnected at an interval; and structures in the airflow flow direction, opposite to the second pipe holes and between the first row of fins and the second row of fins are connected. The heat exchanging fin group can cut off the heat effect of the first row of fins on the maximum area of the second row of fins, so that the influence of the downstream row of fins to the upstream row of fins is smaller, and the situation that the heat exchanging efficiency of the rear row of fins is greatly reduced due to the heat effect can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a heat exchange fin group, a heat exchanger and an air conditioner. Background technique [0002] The fins of the air conditioner internal unit are mainly double-row structure, such as figure 1 As shown, the fins of the two-row structure are connected as a whole. This structural feature will cause the copper tubes and fins in the air inlet section to perform heat exchange first during the process from the air inlet to the air outlet. Since the two rows of fins are connected As a whole, there will be heat conduction and heat transfer between the two, and the heat-affected zone will affect the heat exchange of the fins in the rear section, resulting in a significant decrease in the heat exchange efficiency between the fins in the rear row and the airflow. [0003] Due to the heat-affected zone between the double or multiple rows of fins in the prior art, the heat transfer ...
