Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to an inclined diamond-shaped micro-rib array channel heat exchanger. Background Art

[0002] Micro-fin array channel heat exchangers are characterized by small size, high reliability and high heat transfer coefficient. They have become a mainstream heat exchanger for dissipating heat for integrated, miniaturized and intelligent chips. They can promptly and effectively remove the high heat generated by many electronic chips, avoiding electronic component failure or safety hazards caused by high temperature. With the development of science and technology, micro-fin array channel heat exchangers have been widely used in various aspects such as medical care, military and people's livelihood.

[0003] Existing micro-rib array channel heat exchangers mostly adopt conventional upright rib column structures. The upright rib columns easily increase the flow resistance of the fluid in the channel, thereby increasing the energy required for the pump to transport the fluid, thereby increasing the overall operating cost. At the same time, the upright rib columns may cause uneven distribution of the fluid in the channel, resulting in insufficient heat exchange effect and low heat exchange efficiency of the upright rib columns. Therefore, it does not meet the existing needs, and an inclined diamond micro-rib array channel heat exchanger is proposed. Utility Model Content

[0004] The purpose of the present utility model is to provide an inclined diamond-shaped micro-fin array channel heat exchanger, by arranging diamond-shaped micro-fin columns inside the heat exchange channel, a long diagonal line and a short diagonal line are provided on the cross section of the diamond-shaped micro-fin columns, and the two edges corresponding to the two ends of the long diagonal line on the micro-fin columns are respectively oriented towards the fluid inlet and the fluid outlet, so that the micro-fin columns are in an inclined state, and the cooling water is diverted by the edges of the micro-fin columns, reducing the flow resistance. At the same time, the diamond-shaped micro-fin columns have a larger contact area with the cooling water, thereby improving the heat exchange efficiency and solving the problems in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an inclined diamond-shaped micro-fin array channel heat exchanger, comprising a heat exchanger body and a heat-conducting base, wherein the heat-conducting base is located on the side of the heat exchanger body, and the heat exchanger body is a hollow rectangular structure. A plurality of mutually parallel partitions are arranged inside the heat exchanger body, and the partitions and the heat exchanger body form a plurality of heat exchange channels, one end of the heat exchange channel is a fluid inlet, and the other end of the heat exchange channel is a fluid outlet. Micro-rib columns are arranged inside the heat exchange channel, a flow storage plate is arranged on the side of the heat exchanger body, and a heat-conducting plate is arranged on the side of the heat-conducting base.

[0006] Preferably, a flow storage space is provided inside the flow storage plate, the flow storage space is communicated with the heat exchange channel, and the flow storage space is located on one side of the fluid outlet.

[0007] Preferably, the micro-rib column is a diamond structure, and an inclination angle is set between the micro-rib column and the vertical plane, the inclination angle is at least 20 degrees, one end of the micro-rib column is connected to the heat-conducting base, and the cross-sectional area of the micro-rib column is 0.1256mm 2 .

[0009] Preferably, one side of the heat conducting plate is in contact with the heat source, and the other side of the heat conducting plate is connected to the heat conducting base.

[0010] Preferably, the two opposite edges of the micro-ribs face the fluid inlet and the fluid outlet respectively.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model arranges diamond-shaped micro-ribs inside the heat exchange channel. After the heat emitted by the heat source is absorbed by the heat conduction plate, it is first transmitted to the heat conduction base and then to the micro-ribs. When the cooling water flows along the heat exchange channel and passes through the micro-ribs, the cooling water absorbs the heat and is discharged from the fluid outlet. Compared with the traditional upright ribs, the two opposing edges on the micro-ribs are respectively facing the fluid inlet and the fluid outlet, so that the micro-ribs are in an inclined state, thereby increasing the contact area between the micro-ribs and the cooling water and improving the heat exchange efficiency.

[0013] 2. The utility model arranges diamond-shaped micro-ribs inside the heat exchange channel. When the cooling water passes through the heat exchange channel, the edges on the micro-ribs divert the cooling water, reducing the flow resistance, so that the cooling water can pass through the heat exchange channel faster, thereby improving the heat exchange efficiency; at the same time, after the cooling water passes through the micro-ribs, it first passes through the flow storage space and then is discharged from the fluid outlet. The flow storage space is connected to each heat exchange channel. The flow storage space can adjust the water output of the fluid outlet to ensure that the cooling water is evenly distributed inside each heat exchange channel, avoiding heat accumulation in a certain place, causing thermal stress concentration, and improving the heat exchange effect.

[0020] To solve the problem of insufficient heat transfer effect and low heat transfer efficiency of vertical ribs, please refer to Figure 1-4 , the utility model provides an embodiment: an inclined diamond-shaped micro-fin array channel heat exchanger, comprising a heat exchanger body 1, and a heat-conducting base 3, the heat-conducting base 3 is located on the side of the heat exchanger body 1, the heat exchanger body 1 is a hollow rectangular structure, a plurality of mutually parallel partitions 104 are arranged inside the heat exchanger body 1, the partitions 104 and the heat exchanger body 1 form a plurality of heat exchange channels 101, one end of the heat exchange channel 101 is a fluid inlet 102, and the other end of the heat exchange channel 101 is a fluid outlet 103, the interior of the heat exchange channel 101 is provided with a micro-rib column 5, a flow storage plate 2 is provided on the side of the heat exchanger body 1, and a heat-conducting plate 4 is provided on the side of the heat-conducting base 3, the dimensions of the heat exchange channel 101 are 50mm long * 5.2mm wide * 0.5mm high, the length of the heat-conducting base 3 is 40mm, and the flow rate of the coolant entering from the fluid inlet 102 is 0-1m / s.

[0021] The internal portion of the flow storage plate 2 is provided with a flow storage space 201, which is connected to the heat exchange channel 101 and is located on one side of the fluid outlet 103. The micro-rib column 5 is a diamond structure, and an inclination angle 6 is provided between the micro-rib column 5 and the vertical plane, and the inclination angle 6 is 20°-60°. One end of the micro-rib column 5 is connected to the heat conduction base 3, and the cross-sectional area of the micro-rib column 5 is 0.1256mm. 2 .

[0022] When the cooling water passes through the heat exchange channel 101, the edges on the micro-rib column 5 will divert the cooling water, reducing the flow resistance, so that the cooling water can pass through the heat exchange channel 101 faster, thereby improving the heat exchange efficiency; at the same time, after the cooling water passes through the micro-rib column 5, it first passes through the flow storage space 201 and then is discharged from the fluid outlet 103. The flow storage space 201 is connected to each heat exchange channel 101. The flow storage space 201 can adjust the water output of the fluid outlet 103 to ensure that the cooling water is evenly distributed inside each heat exchange channel 101, avoiding heat accumulation in a certain place, causing thermal stress concentration, and further improving the heat exchange effect.

[0023] The heat-conducting base 3 and the micro-ribs 5 are both made of copper. Cooling water is provided inside the heat exchange channel 101. The inner wall of the heat exchange channel 101 is made of copper.

[0024] After the heat emitted by the heat source is absorbed by the heat conducting plate 4, it is first transferred to the heat conducting base 3 and then to the micro-rib column 5. When the cooling water flows along the heat exchange channel 101 and passes through the micro-rib column 5, the cooling water absorbs heat, and the heated cooling water is discharged from the fluid outlet 103. Compared with the traditional upright rib column, the two opposing edges on the micro-rib column are respectively facing the fluid inlet 102 and the fluid outlet 103, thereby increasing the contact area between the micro-rib column 5 and the cooling water and improving the heat exchange efficiency; at the same time, the coolant will not produce excess substances during the heat exchange and preparation process, is not restricted by geographical conditions when used, and will not pollute or damage the environment.

The cooling water is diverted by the edges of the micro-rib columns 5, reducing the flow resistance. At the same time, the diamond-shaped micro-rib columns 5 have a larger contact area with the cooling water, thereby improving the heat exchange efficiency.
