Description

Technical Field

[0001] The utility model belongs to the technical field of electric vehicle charging, and in particular relates to a liquid-cooled socket terminal. Background Art

[0002] With the development of society and the improvement of people's environmental awareness, new energy vehicles have been favored by more and more consumers, and the importance of charging equipment related to new energy vehicles has gradually become prominent. At present, new energy charging equipment has problems such as low charging power, slow charging, and long charging time. The power terminals in the charging gun need to pass a large current when charging. During use, the current increases, causing the temperature to rise rapidly. Continuous high temperature can easily damage the electronic components of the charging device, and in severe cases it can cause safety accidents such as burning.

[0003] In order to achieve better heat dissipation between the socket and the plug of the charging connector, a cooling structure is generally set in the socket of the electrical connector in the prior art. For example, the patent with publication number: CN115939819A is a socket cooling structure previously applied for by the applicant, which only forms a cooling circulation path, that is, the coolant enters from half of the periphery of the terminal and flows out from the other half of the periphery, and the heat dissipation uniformity is poor. The load connection terminal will still overheat during power transmission; some prior arts also set a double helix structure in the load socket connection terminal to achieve the effect of cooling the socket connection terminal, but due to the gap between the outer cover and the flow channel, the coolant flows from the gap, resulting in the failure of the cooling function, and then the temperature is too high to cause ablation, and when the temperature is too high, the temperature control detection cannot pass, and the charging gun will not charge. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a liquid-cooled socket terminal, in which a flow channel with a spiral micro-guide groove structure is arranged to separate the coolant input end and the output end, and the heat dissipation is uniform. The outer cover is welded to the top wall of the flow channel to prevent leakage, thereby avoiding failure of the liquid cooling function.

[0005] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0006] A liquid-cooled socket terminal, comprising:

[0007] The outer cover has a connection hole recessed at one end thereof for connecting the socket terminal, and a wire installation hole at the other end thereof for connecting the wire;

[0008] The flow channel is covered on the periphery of the connecting hole and is located in the outer cover. The flow channel is in a spiral structure. A connecting portion is provided on the periphery of one end of the connecting hole. The connecting portion is connected to one end of the flow channel. The top wall of the flow channel is welded to the outer cover.

[0009] Furthermore, the flow channel adopts a double helix structure.

[0010] Furthermore, one end of the flow channel is symmetrically provided with a liquid inlet tank and a liquid outlet tank, one end of the flow channel is connected to the liquid inlet tank, and the other end is connected to the liquid outlet tank, one end of the liquid inlet tank is connected to one end of the cooling liquid chiller circulating refrigerator, and one end of the liquid outlet tank is connected to the other end of the cooling liquid chiller circulating refrigerator.

[0011] Furthermore, the outside of the liquid inlet bin and the liquid outlet bin are respectively provided with a bin opening sealing cover, and the sealing cover is provided with a liquid cooling pipe quick connector, and one end of the liquid cooling pipe quick connector is used to connect the liquid cooling pipe.

[0012] Furthermore, a clamp is provided outside the hatch sealing cover, a connecting seat is provided in the middle of the clamp, a channel is provided inside the connecting seat, the channel is connected to the corresponding liquid cooling pipe quick connector, and fasteners are provided at both ends of the clamp.

[0013] Furthermore, a first sealing groove is recessed inwardly at the top of the port sealing cover, and a second sealing groove is recessed correspondingly at one end of the channel. The first sealing groove and the second sealing groove are arranged correspondingly, and sealing members are arranged in the first sealing groove and the second sealing groove.

[0014] The beneficial effects of the utility model are:

[0015] 1. The top wall of the flow channel is welded to the outer cover to avoid the coolant in the hot and cold flow channels from mixing and dispersing. The input and output ends of the coolant are separated, and the heat dissipation is more uniform.

[0016] 2. A double-helix structured micro-guide groove is provided to separate hot and cold into independent flow channels, and a connecting portion is provided at one end of the flow channel, and a liquid inlet tank and a liquid outlet tank are provided at the other end. The coolant flows from the liquid inlet tank into the liquid inlet section of the spiral flow channel, and then the connecting portion enters the liquid outlet section of the spiral channel and flows out from the liquid outlet tank with the heat removed and then flows into the liquid cooler circulating refrigeration machine, so that the liquid cooling socket can withstand a higher current when charging.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0027] like Figure 1-Figure 7 As shown, this embodiment provides a liquid-cooled socket terminal including: an outer cover 100 and a flow channel 200 disposed in the outer cover 100. The front end of the outer cover 100 is recessed inwardly and provided with a connection hole 120, and the connection hole 120 is used to connect the socket terminal. The rear end is provided with a wire installation hole 110, and is used to connect the wire. The flow channel 200 covers the outer periphery of the connection hole 120 and is located in the outer cover 100. A connecting portion 210 is provided at the front end of the flow channel 200. The connecting portion 210 is located at the outer periphery of the front end of the connection hole 120 and is disposed in the outer cover 100. In order to achieve a better heat dissipation effect, the flow channel 200 is extended by a predetermined length along the rear end of the connection hole 120 in the direction of the guiding installation hole 110, so that the outer wall of the liquid-cooled socket terminal is cooled. The flow channel 200 is spirally wound inside the outer cover 100 to form a spiral micro-guide groove structure. One end of the flow channel 200 is connected to the coolant input end, and the other end is connected to the coolant output end, so that the coolant enters one end of the flow channel 200 through the coolant input end and flows to the connecting portion 210, then flows to the other end of the flow channel 200 through the connecting portion 210, and then flows to the coolant output end through the other end of the flow channel 200, so as to cool the area around the connecting hole 120 and between the connecting hole 120 and the wire installation hole 110. The top of the flow channel 200 is connected to the outer cover 100 by ultrasonic welding, so that the outer cover 100 and the top wall of the flow channel 200 are closed to avoid the coolant in the cold and hot flow channels from dispersing and mixing, which may cause cooling failure.

[0028] Specifically, Figure 6 As shown, the flow channel 200 adopts a double helix structure to increase the flow rate of the coolant entering the flow channel 200 and improve the uniformity of heat dissipation. The connecting portion 210 divides the spiral structured flow channel 200 into a liquid inlet section and a liquid outlet section. When in use, the coolant flows from the liquid inlet bin into the liquid inlet section of the spiral flow channel, and then the connecting portion enters the liquid outlet section of the spiral channel and flows out of the liquid outlet bin with the heat removed and then flows into the liquid cooler circulating refrigeration machine, so that the liquid cooling socket can withstand a higher current when charging.

[0029] Specifically, Figure 3-Figure 5 As shown, the rear end of the flow channel 200 is symmetrically provided with a liquid inlet tank 121 and a liquid outlet tank 122, and the liquid inlet tank 121 and the liquid outlet tank 122 are located between the wire installation hole 110 and the flow channel 200, one end of the flow channel 200 is connected to the liquid inlet tank 121, and the other end is connected to the liquid outlet tank 122, one end of the liquid inlet tank 121 is connected to the liquid outlet end of the cooling liquid chiller circulating refrigerator, and one end of the liquid outlet tank 122 is connected to the liquid return end of the cooling liquid chiller circulating refrigerator, thereby forming a reflux path.

[0030] Specifically, Figure 5 As shown, the outside of the liquid inlet bin 121 and the liquid outlet bin 122 are respectively provided with a bin opening sealing cover 123, and the outside of the bin opening sealing cover 123 is provided with a liquid cooling pipe quick connector 130, one end of the liquid cooling pipe quick connector 130 is facing one side of the wire installation hole 110, and is connected to the liquid cooling pipe, so that the liquid cooling pipes corresponding to the corresponding liquid cooling pipe quick connector 130 are respectively connected to the liquid outlet end and the liquid return end of the cooling liquid chiller circulation refrigeration machine.

[0031] Preferably, the outer cover and the port sealing cover 123 are integrally formed to ensure sealing.

[0032] Specifically, Figure 1-Figure 3 , Figure 7 As shown, a clamp 131 is provided on the outside of the port sealing cover 123, a connecting seat 133 is provided in the middle of the clamp 131, and a channel 134 is provided in the connecting seat 133, so that the channel 134 of the connecting seat 133 on one clamp 131 is connected to the other end of the liquid cooling pipe quick connector 130 on the corresponding side, and fasteners 132 are provided at both ends of the clamp 131, so that the clamp 131 presses the connection between the channel 134 and the port sealing cover 123.

[0033] Specifically, Figure 3 , Figure 7 As shown, in order to further improve the sealing performance, a first sealing groove 135 is recessed inwardly at the top of the port sealing cover 123, and a second sealing groove 136 is recessed at one end of the channel 135 facing the top of the port sealing cover 123, so that the first sealing groove 135 and the second sealing groove 136 are arranged correspondingly, and a sealing member is arranged therein.

[0034] Specific application process:

[0035] Insert one end of the liquid cooling tube 124 into the corresponding sealing cover 123, put the liquid cooling tube quick connector 130 on one end of the liquid cooling tube 124, and set the two clamps 131 opposite to each other, lock them with the fastener 132, and then connect the other end of each liquid cooling tube 124 to the corresponding liquid inlet and outlet of the liquid cooling machine circulation refrigerator, so that a cooling reflux circulation channel is formed inside the socket terminal. When the socket liquid cooling terminal is working, the heat generated by the connection part is taken away, thereby improving the cooling effect of the connection part.

[0036] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
