[0031] Most of the existing liquid cooling cables currently use the wires in the cable as conductors and conduits to form a cooling liquid circulation loop inside the wires. The existing connection method is to directly connect the wires without a transition section, which causes flow resistance when the coolant circulates through the circulation loop and passes through the connecting port, thereby greatly reducing the liquid cooling effect.

[0032] The utility model provides a liquid cooling wire.

[0033] In the embodiment of the utility model, the liquid-cooled wire 100 includes: a first conduit 110, the first conduit 110 has a first flow cavity for conveying insulating coolant; a second conduit 120, the second conduit 120 has a second flow cavity for conveying insulating coolant; and a connecting pipe 130, the connecting pipe 130 connects the first conduit 110 and the second conduit 120 to communicate the first flow cavity and the second flow cavity, the first conduit 110, the second conduit 120 and the connecting pipe 130 are all made of conductive materials, and the connecting pipe 130 is used to output the current transmitted through the first conduit 110 and the second conduit 120. Figure 4-5As shown in the figure, the liquid-cooled wire 100 is composed of a first conduit 110, a second conduit 120 and a connecting pipe 130, and the connecting pipe 130 connects the first conduit 110 and the second conduit 120. Since the first conduit 110 and the second conduit 120 are hollow structures, the hollow parts form a first flow cavity and a second flow cavity respectively. When the connecting pipe 130 connects the first conduit 110 and the second conduit 120, the first flow cavity formed in the first conduit 110 and the second flow cavity formed in the second conduit 120 are connected through the connecting pipe 130. When the liquid-cooled wire 100 is put into use, insulating coolant will flow inside it, thereby playing a role in heat dissipation of the liquid-cooled wire 100. Since the first flow cavity in the first conduit 110 and the second flow cavity in the second conduit 120 are connected through the connecting pipe 130, a circulation loop for insulating coolant is formed, so that the first conduit The cold source device connected to the pipe 110 and the second pipe 120 at one end away from the connecting pipe 130 can form a circuit for the circulation of red insulating coolant through the first circulation cavity, the connecting pipe 130 and the second circulation cavity. Because the first pipe 110 and the second pipe 120 are both made of conductive materials, and the connecting pipe 130 is also made of conductive materials, when the first pipe 110 and the second pipe 120 are connected through the connecting pipe 130, a single-phase wire with the connecting pipe 130 as the output end is formed. Through the setting of the connecting pipe 130, the insulating coolant can flow more smoothly from the first circulation cavity to the second circulation cavity under the promotion of the cold source device, and then flow back to the cold source device through the second circulation cavity for cooling treatment. Through such a setting, the insulating coolant can circulate more smoothly, thereby indirectly improving the insulating coolant to achieve efficient and rapid cooling treatment of the liquid-cooled wire 100.

[0034] Specifically, Figure 5 As shown, in one embodiment, the connecting pipe 130 includes a first connecting section 1301, a second connecting section 1302 and an arc section 1303, wherein the arc section 1303 connects the first connecting section 1301 and the second connecting section 1302, wherein the first connecting section 1301 is connected to the first conduit 110, and the second connecting section 1302 is connected to the second conduit 120. In order to further improve the flow of the insulating coolant from the first flow cavity in the first conduit 110 to the second flow cavity in the second conduit 120, the connecting section of the connecting pipe 130 is configured as an arc section 1303, and in order to further facilitate the connection between the connecting pipe 130 and the first conduit 110 and the second conduit 120, the first connecting section 1301 and the second connecting section 1302 are further configured on both sides of the arc section 1303. By such a configuration, the connecting pipe 130 is not only convenient for connecting with the first conduit 110 and the second conduit 120, but also can better circulate and transport the insulating coolant through the arc section 1303.

[0035] More specifically, Figure 5 As shown, in one embodiment, the first connection section 1301 is sealed and welded to the first conduit 110, and the second connection section 1302 is sealed and welded to the second conduit 120. In order to ensure the sealing effect of the connection between the connecting pipe 130 and the first conduit 110 and the second conduit 120, the first connection section 1301 of the connecting pipe 130 and the first conduit 110 can be sealed and welded by welding, and the second connection section 1302 of the connecting pipe 130 and the second conduit 120 can also be sealed and welded by welding. Of course, when the first connection section 1301 and the second connection section 1302 are connected to the first conduit 110 and the second conduit 120, a threaded adapter can also be used to achieve a tight connection.

[0036] Further, such as Figure 4-5 As shown, in one embodiment, the first connecting section 1301, the second connecting section 1302 and the arc section 1303 are connected to form a "U" shape. The U-shaped connecting pipe 130 has the best conduction effect when it is put into connection with the first conduit 110 and the second conduit 120.

[0037] In one embodiment, in order to facilitate the connection of the liquid cooling wire 100 with an external plug or socket, as shown in FIG. Figure 4-5 As shown, the liquid-cooled wire 100 further includes a connection terminal 140, which is disposed at the arc segment 1303 and extends in a direction away from the arc segment 1303. Since the connecting pipe 130 is used as an output end, in order to facilitate the connection between the connecting pipe 130 and other components, a connection terminal 140 connected to an external component is protrudingly disposed at the arc segment 1303 of the connecting pipe 130, and the connection terminal 140 is disposed in a direction away from the opening of the arc segment 1303. Of course, the connection terminal 140 is also supported by a conductor material, and the connection terminal 140 can be fixedly installed on the connecting pipe 130 by screwing, or fixed on the connecting pipe 130 by welding.

[0038] In one embodiment, the insulating coolant is dimethyl silicone oil.

[0039] The utility model also proposes a liquid-cooled cable 200, the liquid-cooled cable 200 includes at least one liquid-cooled wire 100 according to any one of claims 1-6, the liquid-cooled cable 200 also includes a protective cover 210, the liquid-cooled wire 100 is arranged in the protective cover 210, the protective cover 210 is filled with insulating material, and when there are at least two liquid-cooled wires 100, the space between any two of the liquid-cooled wires 100 is filled with insulating material. The specific structure of the liquid-cooled cable 200 refers to the above-mentioned embodiment. Since the liquid-cooled cable 200 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here. Among them, Figure 1-3 As shown, in order to provide protection for the liquid-cooling wire 100 arranged inside the liquid-cooling cable 200, a protective cover 210 is provided on the periphery of the liquid-cooling wire 100. The protective cover 210 is made of insulating material, such as polyethylene, rubber or glass fiber, etc., and no excessive requirements are made here. Since at least two liquid-cooling wires 100 are required in the liquid-cooling cable 200 to constitute a two-phase transmission circuit for use, in order to prevent the two liquid-cooling wires 100 from contacting each other and causing a circuit short circuit, the periphery of the two liquid-cooling wires 100 is filled with insulating material inside the protective cover 210. The insulating material can prevent the two liquid-cooling wires 100 from contacting each other and further protect the liquid-cooling wires 100 from being damaged by external forces.

[0040] In one embodiment, the insulating material is a rubber filling layer 230. Of course, the insulating material can also be an insulating filling material such as plastic.

[0041] In one embodiment, the liquid cooling cable 200 further includes a connecting sleeve 220, which has an opening for the first conduit 110 and the second conduit 120 to pass through, and the connecting sleeve 220 is disposed at one end of the first conduit 110 and the second conduit 120 close to the connecting pipe 130. Figure 1-2 As shown, in order to make the protective sleeve 210 and the insulating material filled in the protective sleeve 210 better protect the liquid-cooled wire 100, a connecting sleeve 220 is installed at one end of the first conduit 110 and the second conduit 120 in the liquid-cooled wire 100 close to the connection with the connecting pipe 130 to seal the opening of the protective sleeve 210.

[0042] Specifically, in one embodiment, the liquid cooling cable 200 includes at least two liquid cooling wires 100, and the connecting pipes 130 of the at least two liquid cooling wires 100 are arranged to be inclined in opposite directions. Figure 1-3As shown, two liquid-cooling wires 100 are arranged in the protective cover 210 of the liquid-cooling cable 200, so two groups of first conduits 110 and second conduits 120 are arranged inside the liquid-cooling cable 200. In order to conveniently connect the connecting pipe 130 with one group of the first conduits 110 and the second conduits 120 in the liquid-cooling cable 200, and facilitate the connection of the other group of the first conduits 110 and the second conduits 120 with the connecting pipe 130, the connecting pipe 130 is arranged in an inclined state. Such an arrangement can leave more space for installing another connecting pipe 130 after the connecting pipe 130 and the first group of the first conduits 110 and the second conduits 120 are installed. Such an arrangement makes it more convenient to install the connecting pipe 130. Of course, there can also be three liquid-cooling wires 100 in the liquid-cooling cable 200 to form a three-phase transmission circuit.
