Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a blowing plate heat exchanger. Background Art

[0002] The inflatable heat spreader is a new type of two-phase heat dissipation product. It has no capillary structure inside and is processed by printing, hot rolling, cold rolling, inflating and other processes. The refrigerant evaporates and condenses continuously in the plate with a specific circuit channel, relying on the phase change of the working fluid to efficiently transfer heat. It originated from the refrigerator evaporator and heat pump evaporator. The main technical points include refrigerant design, pipeline optimization and pressure design.

[0003] The disadvantage of the existing technology is that the heat exchange of the blown plate heat exchanger requires internal flow channels to provide heat, and the distribution of the flow channels determines the heat exchange efficiency and the heat exchange area. However, the flow channels cannot be increased indefinitely, because the size, thickness, and dimensions of the flow channels determine the internal pressure limit that the blown plate itself can withstand, and cannot be infinitely large. Since the refrigerant is generally used inside, and the pressure of the refrigerant increases with the increase of temperature, if it cannot withstand a large pressure, the refrigerant cannot flow inside.

[0017] Here, it should be noted that the functions and methods involved in the present invention are merely conventional adaptive applications of the prior art. Therefore, the improvement of the present invention on the prior art is essentially the connection relationship between the hardware, rather than the functions and methods themselves. That is, although the present invention involves some functions and methods, it does not include improvements to the functions and methods themselves. The description of the functions and methods in the present invention is to better illustrate the present invention so as to better understand the present invention.

[0018] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0019] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0020] See also Figure 1The present application discloses a blown plate heat exchanger, comprising a blown plate body 1, wherein the blown plate body 1 has a heat transfer area 2, wherein a refrigerant filling port 5 is disposed on one side of the heat transfer area 2, wherein a plurality of partitions 3 are provided at intervals in the heat transfer area 2, wherein the partitions 3 are circular structures made of pure aluminum, and the intervals between the partitions 3 form a refrigerant flow channel 4.

[0021] The present application sets a circular structure partition 3 made of pure aluminum in the heat transfer zone 2, and forms a refrigerant flow channel 4 between the partitions 3. With this structure, the entire heat transfer zone 2 is evenly covered with the refrigerant flow channel 4. The refrigerant can be poured into the heat transfer zone 2 through the refrigerant filling port 5 and flow in the refrigerant flow channel 4. The refrigerant can spread over the entire heat transfer zone 2 through the refrigerant flow channel 4, so that the temperature of the entire heat transfer zone 2 is uniform, which solves the problem of uneven temperature of the blowing plate caused by the refrigerant not being able to cover the flow channel.

[0022] The blowing plate body 1 and the heat transfer zone 2 are both L-shaped structures. The blowing plate body 1 includes a first side, a second side, a third side, a fourth side, a fifth side and a sixth side. The second side and the third side are opposite to the first side, and the fourth side and the fifth side are adjacent to the first side. One end of the fourth side is connected to one end of the first side, and the other end of the fourth side is connected to one end of the second side. One end of the fifth side is connected to the other end of the first side, and the other end of the fifth side is connected to one end of the third side. The other end of the third side is connected to one end of the sixth side, and the other end of the sixth side is connected to the other side of the second side. The first side, the second side, the third side, the fourth side, the fifth side and the sixth side are connected end to end to form an L-shaped structure.

[0023] The length of the first side is 750 mm, the length of the second side is 400 mm, the length of the third side is 350 mm, the length of the fourth side is 450 mm, the length of the fifth side is 150 mm, and the length of the sixth side is 300 mm.

[0024] The partition 3 is made of solid pure aluminum material, which is a circular structure. The radius of the partition 3 is 4.5mm. A number of partitions 3 cover the L-shaped heat transfer area 2 and are arranged in a rectangular array. The part between two adjacent partitions 3 is made into a refrigerant flow channel 4 through a blowing process for the refrigerant to flow. The distance between two adjacent partitions 3 is 4.1-5.2mm. In this embodiment, the distance between two adjacent partitions 3 is 4.5mm. It is proved by calculation and experiment that when the distance between two adjacent partitions 3 is set to 4.5mm, the formed refrigerant flow channel 4 can ensure that the internal pressure reaches 5MPA, which can meet the pressure of most refrigerants and ensure the cooling effect.

[0025] The edge of the heat transfer zone 2 is a wavy structure, which ensures the uniformity of the distance between the edge of the heat transfer zone 2 and the adjacent partition 3, so that the width of the flow channel is always maintained between 4.1 and 5.2 mm, and finally can be maintained at 4.5 mm, thereby ensuring the cooling effect.
