Technical Field

[0001] The utility model relates to a novel evaporator fin, belonging to the field of evaporators. Background Art

[0002] The existing fins are single-piece, and the fin spacing on the windward side is small. During use, the windward side of the air cooler is quickly clogged with frost, requiring frequent shutdowns to defrost, which increases power consumption and reduces evaporator efficiency. Summary of the Invention

[0003] According to the background problem, the problem to be solved by the present invention is:

[0004] Frequent frost formation and easy blockage of the windward side require frequent machine shutdowns and cleaning;

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A new type of evaporator fin is characterized in that it includes fin A, fin B and a connecting rod, and both fin A and fin B are provided with mounting holes and spoiler holes; fin A is square, and fin B consists of a square fin body and a wavy spoiler; the connecting rod passes through the mounting hole to fix fin A and fin B, and fin A and fin B are arranged alternately.

[0007] Preferably, the mounting holes are arranged in a matrix on the fins A and B, and the spoiler holes are also arranged in a matrix, and the spoiler holes are provided below or above the mounting holes.

[0008] Preferably, the spacing between the fins A and B is 5-10 cm.

[0009] The utility model realizes the reasonable arrangement and combination of A and B fins, widens the distance between the windward surface fins, increases the geometric area of the air flow channel, delays the frost blockage time of the windward surface, and at the same time, the spoiler cooperates with the spoiler hole to realize three-dimensional disturbance of the incoming air flow. The enhancement of air flow turbulence is conducive to blowing off frosted ice crystals and reducing the frosting speed on the windward surface. The multi-faceted effects increase the defrost interval time, reduce power consumption, and improve the evaporator efficiency.

[0010] The beneficial effects of the utility model are:

[0011] The arrangement of the A and B fins of the utility model is simple and easy to install; the distance between the windward fins is widened, making it easy to observe the frost condition during the process;

[0012] The utility model delays the frost blocking time of the windward side, reduces the number of shutdowns for frost collection, reduces power consumption, and improves the efficiency of the evaporator. BRIEF DESCRIPTION OF THE DRAWINGS
