Description

Technical Field

[0001] The utility model relates to the field of heat dissipation of electronic equipment, in particular to an anti-blocking heat exchange fin group structure. Background Art

[0002] The working principle of the liquid cooling radiator is: under the action of the pump, the cold liquid brings the heat from the heat exchange area to the heat dissipation radiator through flow, and the heat is dissipated into the air through forced convection by the fan. The cooled cold liquid returns to the heat exchange area to absorb heat, and the cycle continues.

[0003] The flow and heat transfer in the cold head has an important influence on the performance and operation status of the entire system. The conventional cold head structure mainly includes a cover, a rubber pad, a water barrier, a shell, a metal sheet, a diverter plate, and a base.

[0004] like Figure 1 As shown, the base 10 mainly includes a heat exchange groove 101 arranged on the upper surface of the base, an integral structure with the base, a plurality of heat exchange fin groups 102 extending vertically upward from the bottom of the heat exchange groove 101, and a microcirculation channel 103 formed between the plurality of heat exchange fin groups. The bottom surface of the base 10 is used to be in contact with the core heating surface of the heating body (such as CPU or GPU, etc.), and the upper surface of the base 10 is used to be combined with the diverter seat (not shown) to form a heat exchange cavity. The coolant enters the heat exchange groove 101 from the diverter seat and flows along the plurality of microcirculation channels, and fully contacts and exchanges heat with the heat exchange fin group 102. The heat exchange fin group 102 increases the contact heat exchange area between the coolant and the base, which can greatly improve the heat exchange efficiency.

[0005] However, the base 10 is generally made of a high thermal conductivity material such as copper or aluminum. Copper or aluminum will produce some chemical reactions with the coolant at high temperatures and produce some flocs. These flocs sometimes accumulate in a certain part of the microcirculation channel 103 between the heat exchange fins (see Figure 1 ), blocking the microcirculation channel. Since the top of the heat exchange fin group is usually in contact with the diverter seat, that is, in general, the coolant can only enter and exit from the openings at both ends of the microcirculation channel, but not from the top. Once a blockage occurs, the entire microcirculation channel will be completely blocked, and the coolant cannot continue to circulate in the microcirculation channel, resulting in the impact on the heat exchange efficiency of the entire heat exchange fin group.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0007] The utility model aims to provide an anti-blocking heat exchange fin group structure, which can circulate and dissipate heat through the shunt channel of the anti-blocking shunt structure when the microcirculation channel is blocked.

Adjacent heat exchange fins are separated by a distance, and the distance forms a microcirculation channel. The heat exchange fin group structure includes at least one group of anti-clogging shunt structures, each of which is arranged on each heat exchange fin. The anti-clogging shunt structures on each group of heat exchange fins form a shunt channel at an angle to the microcirculation channel. When a microcirculation channel is blocked, the coolant in the microcirculation channel can be shunted and circulated through the shunt channel.

[0010] In a preferred embodiment, the number of at least one group of anti-blocking and diverting structures is multiple, the multiple groups of anti-blocking and diverting structures have different structures, sizes and shapes, and the multiple diverting channels are not parallel to each other.

[0011] In a preferred embodiment, each set of anti-blocking and diverter structures is a notch disposed on the top of each heat exchange fin.

[0012] In a preferred embodiment, the shape of the notch is V-shaped, inverted trapezoidal, rectangular or arc-shaped.

[0013] In a preferred embodiment, the depth of the notch is 1 / 4, 1 / 3, 1 / 2 or 1 of the height of the heat exchange fin.
