Description

Technical Field

[0001] The utility model relates to the technical field of cooling, in particular to an energy-saving and noise-reducing micro-cooling channel. Background Technique

[0002] In precision electronic instruments, liquid cooling is usually required for cooling. The liquid generally circulates in the heat dissipation system of the device, thereby taking away the heat generated by the device to achieve the purpose of cooling the device. The liquid can be a cooling medium such as water, ethylene glycol aqueous solution, fluorinated liquid, oil, etc. The traditional micro-cooling channel uses two header pipes, and is connected by multiple cooling pipes. The two ends of the cooling pipe extend into the two header pipes for welding and sealing. The two ends of the existing cooling pipe are both flat, as Figure 1 and Figure 2 shown. Since the coolant needs to flow through the two header pipes, the flat shape not only hinders the flow of the coolant, increases the resistance, increases the power consumption, but also generates noise. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the utility model provides an energy-saving and noise-reducing micro-cooling channel, which can not only reduce the resistance of the coolant flowing through the header pipe, reduce the power consumption, but also reduce the noise.

[0004] To achieve the above purpose, the utility model provides the following technical solution: an energy-saving and noise-reducing micro-cooling channel, including a first header pipe, a second header pipe and a plurality of cooling pipes. The two ends of the cooling pipe are respectively connected to the first header pipe and the second header pipe, and the first header pipe is provided with a liquid inlet and a liquid outlet. The two ends of the cooling pipe extending into the first header pipe and the second header pipe are of a concave arc structure.

[0005] Preferably, the cooling pipe is flat and hollow, and is internally provided with a plurality of strip partitions. The adjacent two partitions form a trapezoidal water channel. The flat and hollow cooling pipe can increase the heat dissipation area, and the trapezoidal water channel can dissipate heat better.

[0006] Preferably, a corrugated fin is provided between adjacent cooling pipes. The fin can increase the heat dissipation area and has a better heat dissipation effect

[0007] Preferably, valves are provided at two positions near the ends of the first header pipe. When the internal coolant decreases, the valves can be opened for adding liquid, discharging liquid, or exhausting gas.

[0008] Preferably, a baffle is provided in the middle of the inner cavity of the first header pipe. To prevent the coolant from entering the inner cavity of the first header pipe through the liquid inlet and directly discharging from the liquid outlet, and to improve the flow path of the coolant.

[0009] Preferably, the two ends of the first header pipe and the second header pipe are provided with sealed end caps. The sealing effect is good and it is convenient for installation.

[0010] Compared with the prior art, the utility model provides an energy-saving and noise-reducing micro-cooling channel, which has the following beneficial effects:

[0011] Since the two ends of the cooling pipe of the utility model extending into the first header pipe and the second header pipe are of concave arc structures. The concave arc structures can not only reduce the resistance of the coolant flowing through the header pipes, but also achieve the same coolant flow rate effect as that at high power consumption while at low power consumption. After the blockage is reduced, the noise can naturally be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the utility model without creative efforts shall fall within the protection scope of the utility model.

[0022] Embodiment 1, see Figure 3-9As shown in the figure, an energy-saving and noise-reducing micro-cooling channel includes a first header pipe 1, a second header pipe 2, and several cooling pipes 3. The first header pipe 1 and the second header pipe 2 are circular tubes with a central hole for passing coolant. Sealed end caps 11 are welded to both ends of the first header pipe 1 and the second header pipe 2. Valves 9 are provided at two positions near the ends of the first header pipe 1. Due to phenomena such as coolant leakage, the valves 9 can be opened to add coolant at any time. Moreover, when cleaning is required, the coolant can be emptied through the valves 9, and it can also be used for exhaust. See Figure 7 As shown in the figure, a baffle 10 is provided in the middle of the inner cavity of the first header pipe 1. Since the first header pipe 1 has an inlet 4 and an outlet 5, the baffle 10 prevents the coolant from entering the inner cavity of the first header pipe 1 through the inlet 4 and directly discharging from the outlet 5, improving the flow path of the coolant and enhancing the heat dissipation effect.

[0023] See Figure 8 and 9 As shown in the figure, the cooling pipes 3 are flat and hollow. Several cooling pipes 3 are provided according to the heat dissipation requirements. Corrugated fins 8 are provided between adjacent cooling pipes 3 and are evenly distributed. See Figure 9 As shown in the figure, there are several strip partitions 6 inside the cooling pipes 3. The inclination angles of every other partition 6 among the partitions 6 are the same. Therefore, adjacent two partitions 6 form a trapezoidal water channel 7. This is convenient for increasing the flow rate and has a good heat dissipation effect.

[0024] See Figure 3 As shown in the figure, the two ends of the cooling pipes 3 are respectively connected to the first header pipe 1 and the second header pipe 2. Due to the need of the welding process, the cooling pipes 3 need to extend into the inner cavities of the first header pipe 1 and the second header pipe 2. In the prior art, see Figure 1 and 2 As shown in the figure, compared with the present application Figure 6 and 7 As shown in the figure, the two ends of the cooling pipes 3 are of concave arc 61 structure. When the coolant flows through the first header pipe 1 and the second header pipe 2, the flow area is larger and the resistance is smaller. The same coolant flow rate effect as that of high power consumption can be achieved at low power consumption. After reducing the blockage, the noise can naturally be reduced.
