Embodiment 1

[0029] The invention provides a conformal heat exchanger based on porous flat tubes, which is improved on the basis of conventional mechanical processing and welding, and the conventional mechanically processed liquid-cooled flow channel is replaced by a porous flat tube embedded welding method. It not only reduces the difficulty of processing, but also improves the success rate of welding, and is also conducive to the formation of curved surfaces. The main components are as Figure 2 to Figure 5 As shown, it includes a liquid cooling chamber base plate 1 , a porous flat tube 2 and a flow channel cover plate 3 . One side of the liquid cooling chamber substrate 1 is processed with an internal flow channel cavity 1c, and the porous flat tube 2 is welded in the internal flow channel cavity 1c. The flow channel cover plate 3 is connected to the liquid cooling chamber substrate 1 and seals to cover the inner flow channel cavity 1c. Since the base plate of the liquid cooling chamb...

Embodiment 2

[0034] This embodiment provides another conformal heat exchanger. The porous flat tube 2 is embedded in the liquid cooling chamber substrate 1 (that is, the curved shell) to realize rapid prototyping and welding. At the same time, the profile flat tube can be bent to a certain extent. Successfully integrated the conformal heat exchanger into the curved shell of the system, achieved the expected heat dissipation effect and reduced the system volume.

[0035] In this example, a conformal heat exchanger is formed by welding the liquid cooling chamber substrate 1 , the flow channel cover plate 3 , the liquid inlet joint 5 , the liquid outlet joint 4 , and the porous flat tube 2 into one body.

[0036] The liquid cooling cavity substrate 1 is formed by numerical control machining or 3D printing. The outer surface is arranged with heat dissipation fins, which exchange heat with the external environment and export the heat in the thermal fluid, and the outer surface is also arranged ...

Description

technical field [0001] The invention relates to heat dissipation technology of electronic equipment, in particular to a conformal heat exchanger based on porous flat tubes. Background technique [0002] Liquid cooling is a common cooling method for high heat generating devices in the electronics industry. However, after the liquid takes away the heat from the device, it needs to transfer the carried heat to the surrounding environment, and then re-cool the heat-generating device. The common way is that the liquid flows through an independent air-to-liquid heat exchanger, and the heat is taken away by the fan blowing on the fins in the heat exchanger. When the volume of the system is limited or the fan cannot be used in a closed environment, the liquid can only exchange heat through the conformal heat sink integrated with the system shell. This kind of heat exchanger arranges cooling fins on the system shell, and uses the natural convection or forced convection between the ...
