Description

Water drainage unit and device thereof

The present invention relates to a water discharge unit and a device thereof, and more particularly to a water discharge unit and a device thereof which reduce thermal impedance and can greatly improve heat exchange efficiency.

The use of heat sinks in modern technology products is very common, especially in the computer, information and communication industries. Since there are many sophisticated electronic components in the technology products, the stability of their operation is very important, especially the heat dissipation effect is especially important.

At present, a heat dissipating device that can be installed on various electronic components and has a heat dissipating effect is commonly provided, and a fan device is disposed above the heat dissipating device to blow away the heat inside the heat dissipating device to achieve the effect of dissipating heat. In general, higher-order electronic devices usually use a water-cooled discharge device. The principle is that the working fluid is forced to circulate away from the heat of the water-cooling device under the driving of the pump, which is quieter and cooler than air-cooling. Little dependence on the environment.

In detail, referring to FIG. 8 , the water-cooling device 1 includes a plurality of fins 10 that are bent in a shape, a plurality of flat tubes 11 are arranged at intervals, and two water tanks 12 are formed. The heat sink fins 10 are disposed on The flat tubes 11 are disposed between each other, and the fins 10 are bent and welded by soldering between the outer side of the bending point and the outer side of the corresponding flat tubes 11 . a little contact (non-face contact), the two side water tanks 12 and the heat dissipating fins 10 and the two sides of the flat tubes 11 are also welded by soldering, so that the two side water tanks 12 and the The cooling fins 10 and the flat tubes 11 are connected to form the water-cooling device 1 , wherein the water-cooling device 1 has a water inlet 13 and a water outlet 14 respectively connected to two water conduits (not shown), The heat dissipating fins 10 and the water flow flat tubes 11 and the water tank 12 must be sealed to each other by welding. Bonding, welding is a manufacturing process and technology for joining metal or other thermoplastic materials such as plastics in a heated manner. However, when the molten filler added during the welding process is heated, there is often a molten molten filler flowing out to block a part of the fluid inlet and outlet. Or the sealing is not true, causing some fluid to overflow during the operation of the fluid, or the molten residual filler remaining in the hardening causes the appearance of the water-cooling device 1 to be poor.

Moreover, the heat of the working liquid in the flat tubes 11 of the conventional water-cooling device 1 is conducted to the heat-dissipating fins 10 to dissipate heat, but another problem extends, that is, the heat of the working liquid is transferred to the The heat dissipation efficiency of the heat dissipation fins 10 is not good. Since the heat dissipation fins 10 and the flat tubes 11 are soldered by two separate components, the heat dissipation fins 10 are not the flat tubes 11 . A part of itself causes the flat tubes 11 to conduct heat between the heat dissipating fins 10 to cause thermal resistance, so that the flat tubes 11 conduct heat absorbed into the water cooling liquid to the heat dissipating fins on both sides. The heat transfer efficiency on the 10 is poor, which in turn causes a problem that the heat-dissipating efficiency of the entire water-cooling device 1 is lowered (or the heat exchange efficiency is lowered). In addition, since the heat dissipating fins 10 are welded to the outside of the flat tubes 11 on both sides through the outer side of the bending point, the structural strength of the intermediate portions of the heat dissipating fins 10 is relatively weak, and is easily damaged by external force collision (eg, The problem of deformation), and the heat conduction effect between the equal flat tubes 11 and the heat radiating fins 10 is also extremely unsatisfactory.

In addition, the manufacturing method of the conventional water-cooling device 1 also requires a lot of man-hours and production costs, and the manufacturing steps are very complicated, and since the water-cooling device 1 requires welding processing, it is complicated and time-consuming in the assembly process.
