Embodiment Construction

[0044] figure 1 is a schematic front view of a fin according to an embodiment of the present invention; figure 2 yes figure 1 Schematic bottom view of the fin shown; image 3 yes figure 1 Schematic left side view of the fin shown; Figure 4 yes figure 1 Schematic perspective view of the fin shown. Such as Figure 1 to Figure 4 As shown, the embodiment of the present invention provides a fin 100 with a novel structure, which has a first half 10 and a second half 20 that are symmetrical about a geometric axis of symmetry. In particular, the inner angle and the outer angle formed by the first half 10 and the second half 20 at the junction of the geometric symmetry axis are both larger than 120°. The length of the geometric connection line between the inner edge endpoint of the extended end of the first half 10 and the inner edge endpoint of the extended end of the second half is greater than the outer vertex at the junction of the first half 10 and the second half 20 to ...

Abstract

The invention provides a fin. The fin is provided with a first half portion and a second half portion; the first half portion and the second half portion are symmetric about a geometric symmetry axis; the first half portion and the second half portion cross with each other at the combining position of the geometric symmetry axis to form an inner edge included angle and an outer edge included angle; the inner edge included angle and the outer edge included angle are larger than 120 degrees. The length of a geometric connecting line between the inner edge end point of the extending end of the first half portion and the inner edge end point of the extending end of the second half portion is larger than the distance between the top point outside the combination position of the first half portion and the second half portion and the geometric connecting line. In addition, the invention further provides a heat exchanger with the fin and the refrigerator. Due to the special fin structure of the fin, the heat exchanger with the fin and the refrigerator, the heat exchange efficiency of the fin is obviously improved, and the performance of the heat exchanger and the refrigerator is obviously improved.

Description

technical field [0001] The invention relates to heat dissipation, in particular to a fin used for heat dissipation or cooling, a heat exchanger and a refrigerator with the fin. Background technique [0002] Heat sinks, also known as fins, play an important role in the composition of heat sinks and are widely used in technical fields such as refrigerators and air conditioners, as well as heat dissipation of CPUs. At present, the commonly used heat sink materials are copper and aluminum alloy, both of which have their own advantages and disadvantages. Copper has good thermal conductivity, but it is more expensive, difficult to process, has a small heat capacity, and is easy to oxidize. However, pure aluminum is too soft to be used directly. Only the aluminum alloy used can provide sufficient hardness. The advantages of aluminum alloy are low price and light weight, but the thermal conductivity is much worse than copper. Commonly used types of heat sinks are aluminum extruded...
