Description

Water-cooled heat dissipation structure with series flexible tubes

The invention relates to a water-cooling heat dissipation structure, in particular to a water-cooling heat dissipation structure with a series flexible tube.

The heat generated by high-power electronic components is quite amazing, and it is generally preferred to use a water-cooling system to quickly bring out heat to achieve the purpose of cooling.

Referring to FIG. 1 and FIG. 2, for two high-power electronic components 2A, 2B disposed on a substrate 9 (as shown in FIG. 2, only two are represented, the actual number may be at least two or more) In view of the limited installation space, two radiators 3A and 3B corresponding to the two high-power electronic components 2A and 2B are disposed on the water-cooling system 1 in a series manner to simultaneously carry away the two high-power electrons. The heat generated by the components 2A, 2B only needs to use a heat exchanger 4 and a pump 5, with the two radiators 3A, 3B, and the heat exchanger 4 is connected in series by a fluid line 6, the pump 5 With the two heat sinks 3A, 3B, the heat absorbed by the at least two heat sinks 3A, 3B can be quickly taken away by the coolant 7 in the tube of the fluid line 6, and the heat is dissipated through the heat exchanger 4. And exudes.

However, since the sizes of the at least two high-power electronic components 2A, 2B disposed on the substrate 9 may be different, that is, the heights of the at least two high-power electronic components 2A, 2B may be different, as shown in FIG. As shown, the high-power electronic component 2A has a relatively high size, so that at least two high-power electronic components 2A, 2B can be horizontally contacted for the at least two heatsinks 3A, 3B, the at least two heatsinks 3A, 3B The connecting tubes 8 of a specific bending angle are additionally connected, and after the at least two heat sinks 3A, 3B are connected in series by the connecting tube 8 of a specific bending angle, the at least two heat sinks 3A, 3B can be horizontally placed and have Different height settings enable the at least two heat sinks 3A, 3B to horizontally contact the at least two high-power electronic components 2A, 2B, in other words, the at least two heat sinks 3A, 3B and the at least two high-power electrons The elements 2A, 2B can be in sufficient contact to achieve good thermal conductivity.

However, in actual use, once the design height of the two heat sinks 3A, 3B and the actual height of the two high-power electronic components 2A, 2B have excessive errors, they must change the bending angle of the connecting pipe 8, resulting in The installation is troublesome, and the bending angle of the connecting pipe 8 is adjusted on site, and it is also difficult to ensure that the bending angle of the connecting pipe 8 satisfies the requirements, thereby easily causing the at least two heat sinks 3A, 3B and the at least two high-power electronic components 2A, There is a gap between 2B (not shown). The current practice is to use a paste-like thermal grease 9A (shown in Figure 2) to fill the gap to achieve good thermal conductivity. However, the gap is too large, the paste In the case of long-term use, the heat-dissipating paste 9A is likely to have a risk of being dried and failing. Upon failure, the at least two high-power electronic components 2A, 2B are overheated to detract from the risk of stability and longevity.
