Description

Technical Field

[0001] The utility model relates to the technical field of coolers, in particular to a plate-fin cooler. Background Art

[0002] As a type of heat exchange equipment, the cooler is often used to cool the fluid, usually using water or air as a coolant to remove heat. For example, the Chinese patent application number 201910674846.6 discloses a cooler with a leakage channel that can prevent the leakage of cold and hot media, including a core; multiple cold medium layers, hot medium layers and leakage interlayers are arranged in the core; the top and bottom of the core are also provided with a cover plate for sealing the core; the cold medium layer and the hot medium layer are arranged alternately; the leakage interlayer is arranged between the cold medium layer and the hot medium layer; the leakage interlayer is also arranged between the cover plate at the top of the core and the cold medium layer; the leakage interlayer is also arranged between the cover plate at the bottom of the core and the cold medium layer. This patent sets a leakage interlayer between the cold medium layer and the hot medium layer, so that the cold and hot media will not flow through when the partition is damaged.

[0003] However, when using the cooler in the patent, since a leakage interlayer is provided between the cold medium layer and the hot medium layer, the weight and volume of the cooler are increased when the number of cold and hot medium layers is the same. At the same time, the cold and hot medium transfer heat across the leakage interlayer, which reduces the heat transfer efficiency. Utility Model Content

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0031] Embodiment 1:

[0032] like Figures 1 to 3 As shown, a plate-fin cooler provided by Example 1 of the utility model includes a core 0; the core 0 includes a plurality of first medium layers 1 and a plurality of second medium layers 2; the first medium layers 1 and the second medium layers 2 are arranged alternately;

[0033] A partition 3 for partition is arranged between the adjacent first dielectric layer 1 and the second dielectric layer 2; the partition 3 includes an aluminum plate 31 and two metal composite plates 32 for reducing the probability of corrosion and perforation of the aluminum plate 31; the two metal composite plates 32 are respectively fixed on the two sides of the aluminum plate 31; the metal composite plates 32 are the same size as the aluminum plate 31; the metal composite plates 32 and the aluminum plate 31 completely overlap.

[0034] For ease of understanding, Figure 3 The one marked with A is the first dielectric layer 1, the one marked with B is the second dielectric layer 2, and the marked numbers are the layer numbers where the first dielectric layer 1 and the second dielectric layer 2 are located.

[0035] When the plate-fin cooler provided in Example 1 of the utility model is used, the first medium and the second medium flow in the first medium layer 1 and the second medium layer 2 respectively, and the partition 3 separates the first medium and the second medium so that the first medium and the second medium exchange heat across the partition 3.

The probability of corrosion perforation at the same position of the outer metal composite plate 32 and the inner aluminum plate 31 is low. Compared with the prior art that only the metal composite plate 32 is used to isolate the first medium and the second medium, the use of a multi-layer plate structure can reduce the possibility of perforation of the partition 3 and improve the corrosion resistance of the partition 3; the multi-layer plate structure ensures the strength of the cooler partition.
