Description

Technical Field

[0001] The invention relates to the technical field of wire cooling, and in particular to a high-current liquid-cooled aluminum busbar connector. Background Art

[0002] In the development of new energy vehicles, due to the constraints of battery capacity technology development, the demand for lightweight vehicles to alleviate mileage anxiety is increasing, and the demand for weight reduction of wiring harnesses is becoming more and more important. At present, in the wiring harness industry, the use of aluminum wires to replace traditional copper wires for lightweight wiring harnesses has become mature. The battery power wiring harnesses of traditional fuel vehicles and new energy vehicles have already used a large number of aluminum wires to transmit power energy. After using aluminum wires, the wiring harness can achieve a 40% weight reduction compared to the original copper wires, and achieve a cost saving of about 30%. Under the condition that the outer diameter of aluminum wires meets the current carrying capacity of traditional copper wires, the outer diameter of aluminum wires is about 1.3 times that of copper wires. This makes it impossible to use aluminum wires due to space limitations in the design and layout of the vehicle wiring harness. In order to solve the problem of insufficient space for the layout of the vehicle wiring harness caused by the increase in the outer diameter of aluminum wires, the application plan of aluminum busbar wires is proposed. Compared with traditional coaxial circular aluminum wires, the flattened design of aluminum busbar wires reduces space occupancy. Under the same current carrying conditions, the cross-sectional area is reduced by 10%, further reducing the space occupied by the wiring harness. Since the resistance of aluminum wire is greater than that of copper wire, it is easy to generate heat when a large current flows through the aluminum wire. The temperature rise will cause safety hazards. It is usually necessary to cool the heated wire. The conventional cooling method is to install a liquid cooling pipe on the outside of each wire and connect each liquid cooling pipe to a liquid cooling pump. When the circuit is complex, the liquid cooling pipe is also complex. If the heat generated by different wires in the circuit is different, the liquid cooling pump cannot properly adjust the temperature of the liquid cooling pipe according to the heat generated by each wire, resulting in a waste of resources.

[0022] like Figures 1 to 4 As shown, a high-current liquid-cooled aluminum bar connector provided by an embodiment of the present invention includes an aluminum bar 110, a cooling sleeve 120 and an adjustment component.

[0023] Both ends of the aluminum bar 110 are provided with connection terminals 111, and the connection terminals 111 are electrically connected to the aluminum bar 110. The aluminum bar 110 has a first chamber 112 inside, and the first chamber 112 is arranged along the length direction of the aluminum bar 110. The cooling sleeve 120 is sleeved on the outside of the aluminum bar 110, and the cooling sleeve 120 and the aluminum bar 110 are spaced apart. A second chamber 130 can be formed between the inner wall of the cooling sleeve 120 and the outer wall of the aluminum bar 110, and the second chamber 130 is in a relatively closed state. The side wall of the aluminum bar 110 is provided with a first opening 113 and a second opening 114 that connect the first chamber 112 and the second chamber 130, so as to attach Figure 2 and attached Figure 3 As shown, the aluminum bar 110 has an upper end and a lower end, the first opening 113 on the aluminum bar 110 is close to the lower end of the aluminum bar 110 , and the second opening 114 of the aluminum bar 110 is close to the upper end of the aluminum bar 110 . The side wall of the cooling sleeve 120 is provided with a water inlet 140 and a water outlet 150 connecting the second chamber 130 with the external environment. When the cooling sleeve 120 is arranged on the outside of the aluminum bar 110, the cooling sleeve 120 also has an upper end and a lower end. The water inlet 140 and the water outlet 150 are both arranged close to the lower end of the cooling sleeve 120, wherein the water inlet 140 is below the water outlet 150. The coolant can enter the second chamber 130 through the water inlet 140, and the coolant entering the second chamber 130 can enter the first chamber 112 through the first opening 113. The coolant entering the second chamber 130 can be discharged from the second chamber 130 through the second opening 114, and the coolant can be discharged from the second chamber 130 through the water outlet 150. The cooling sleeves 120 on the outside of the conductors of two adjacent aluminum bars 110 are connected, that is, the water outlet 150 of one aluminum bar 110 conductor is connected with the water inlet 140 of the adjacent aluminum bar 110 conductor, avoiding the setting of complex liquid cooling pipes. The adjustment component includes a blocking member, a detection member and a control member; the blocking member can block the first opening 113; the detection member is used to detect the temperature of the coolant after cooling the aluminum bar 110 and the temperature of the coolant entering the second chamber 130; the control member can control the degree of blocking of the first opening 113 by the blocking member according to the relevant data of the detection member, thereby controlling the amount of coolant entering the first chamber 112, and reasonably using the coolant to cool the aluminum bar 110, ensuring that multiple aluminum bar 110 conductors are in the normal working temperature range, thereby avoiding waste of resources.

[0024] A high-current liquid-cooled aluminum bar connector of the present invention connects the cooling sleeves 120 on the outsides of two adjacent aluminum bar 110 conductors when the aluminum bar 110 conductors are put into use, that is, the water outlet 150 of one aluminum bar 110 conductor is connected to the water inlet 140 of the adjacent aluminum bar 110 conductor, thereby avoiding the need to set up complex liquid cooling pipelines. The coolant enters the second chamber 130 through the water inlet 140, part of the coolant enters the first chamber 112 through the first opening 113, and part of the coolant flows directly to the water outlet 150. The coolant entering the first chamber 112 effectively cools the wires of the aluminum bar 110. After the coolant effectively cools the wires of the aluminum bar 110, it is discharged from the first chamber 112 from the second opening 114, and then the coolant after the wires of the aluminum bar 110 are cooled is discharged from the water outlet 150. At the same time, the detection component detects the temperature of the coolant after the aluminum bar 110 is cooled. The detection component can also detect the temperature of the coolant entering the second chamber 130. The control component can control the degree to which the blocking component blocks the first opening 113 according to relevant data of the detection component, thereby controlling the amount of coolant entering the first chamber 112, and reasonably using the coolant to cool the aluminum bar 110 to ensure that the wires of multiple aluminum bars 110 are in a normal working temperature range, thereby avoiding waste of resources.

[0025] In one embodiment, a plurality of first openings 113 are provided at the lower end of the aluminum bar 110 , and the plurality of first openings 113 are evenly distributed along the circumference of the aluminum bar 110 . Accordingly, a plurality of second openings 114 are provided at the upper end of the aluminum bar 110 , and the plurality of second openings 114 are evenly distributed along the circumference of the aluminum bar 110 .

[0026] In one of the embodiments, a spoiler is provided in the first chamber 112, and the spoiler can change the flow speed of the coolant in the first chamber 112. When the degree of blocking of the first opening 113 by the blocking member is determined, the total amount of coolant entering the first chamber 112 through the first opening 113 per unit time is fixed. Under the action of the spoiler, the faster the coolant flows in the first chamber 112, the less the temperature rise of the coolant flowing out through the second opening 114, thereby controlling the temperature of the coolant after cooling the wire of the aluminum bus 110.

[0027] In one of the embodiments, the spoiler is coaxially arranged in the first chamber 112, and the spoiler can be telescopically arranged. When the length of the spoiler changes, the diameter of the spoiler changes, and the change in the length of the spoiler changes synchronously with the degree to which the blocking member blocks the first opening 113. In a specific setting, when the degree to which the blocking member blocks the first opening 113 increases, the spoiler shortens and the diameter of the spoiler increases. When the degree to which the blocking member blocks the first opening 113 decreases, the spoiler lengthens and the diameter of the spoiler decreases, wherein the degree to which the blocking member blocks the first opening 113 is controlled by the control member. In a further setting, when the detection member detects that the temperature of the coolant after the aluminum bar 110 is cooled is greater than the first preset temperature, the control member controls the degree to which the blocking member blocks the first opening 113. The degree of cooling decreases, the spoiler is extended, the diameter of the spoiler is reduced, the total amount of coolant entering the first chamber 112 per unit time increases, the flow rate of the coolant in the first chamber 112 decreases, and the coolant can fully cool down the aluminum bar 110. On the contrary, when the detection component detects that the temperature of the coolant after cooling the aluminum bar 110 is less than the first preset temperature, the control component controls the blocking component to increase the degree of blocking the first opening 113. At this time, the spoiler is shortened, the diameter of the spoiler is increased, the total amount of coolant entering the first chamber 112 per unit time decreases, and the flow rate of the coolant in the first chamber 112 increases, then the heat absorbed by the coolant from the aluminum bar 110 is reduced, thereby ensuring that the temperature of the aluminum bar 110 wire after the coolant cools down is in a stable range. In this embodiment, the first preset temperature is the temperature at which the aluminum bar 110 wire works normally.

[0028] In one embodiment, the blocking member is a blocking sleeve 210, which is arranged in the second chamber 130. The blocking sleeve 210 is sleeved on the outside of the aluminum row 110, and the blocking sleeve 210 is slidably and sealedly connected to the aluminum row 110. When the blocking sleeve 210 slides along the aluminum row 110, the blocking degree of the first opening 113 can be changed. In a further configuration, when the blocking sleeve 210 slides upward along the aluminum row 110, the blocking degree of the first opening 113 by the blocking sleeve 210 increases, and when the blocking sleeve 210 slides downward along the aluminum row 110, the blocking degree of the first opening 113 by the blocking sleeve 210 decreases, wherein when the blocking sleeve 210 slides downward along the aluminum row 110, the spoiler is synchronously extended, and when the blocking sleeve 210 slides upward along the aluminum row 110, the spoiler is synchronously shortened.

[0029] In a further embodiment, a drainage hole 211 is provided on the sealing sleeve 210. When the sealing sleeve 210 slides on the aluminum row 110, the drainage hole 211 on the sealing sleeve 210 can be connected to the first opening 113 on the aluminum row 110. When the sealing sleeve 210 slides upward along the aluminum row 110, the degree of connection between the first opening 113 and the drainage hole 211 decreases. When the sealing sleeve 210 slides downward along the aluminum row 110, the degree of connection between the first opening 113 and the drainage hole 211 increases.

[0030] In one embodiment, the detection element includes a first temperature detector and a second temperature detector, the first temperature detector is used to detect the temperature of the coolant entering the second chamber 130; the second temperature detector is used to detect the temperature of the coolant after cooling the aluminum bar 110, and the first temperature detector and the second temperature detector can accurately measure the coolant temperature at the corresponding position. In another embodiment, the detection element can also be a first thermocouple and a second thermocouple, the first thermocouple is used to detect the temperature of the coolant entering the second chamber 130; the second thermocouple is used to detect the temperature of the coolant after cooling the aluminum bar 110.

[0031] In one embodiment, the control member includes a first telescopic rod 310, a second telescopic rod 320 and a control panel. The first telescopic rod 310 and the second telescopic rod 320 are arranged in the second chamber 130. The first telescopic rod 310 and the second telescopic rod 320 both have a fixed end and a telescopic end. The fixed ends of the first telescopic rod 310 and the second telescopic rod 320 are both fixedly arranged on the inner wall of the cooling sleeve 120. The telescopic ends of the first telescopic rod 310 and the second telescopic rod 320 are both connected to the blocking sleeve 210. When the first telescopic rod 310 and the second telescopic rod 320 are extended, they can push the blocking sleeve 210 to slide downward along the aluminum bar 110. The control panel can receive data from the first temperature detector and the second temperature detector, and the control panel can control the length change of the first telescopic rod 310 and the second telescopic rod 320 according to the received data. In a specific setting, the control board controls the length of the first telescopic rod 310 to change according to the data of the first temperature detector, and controls the length of the second telescopic rod 320 to change according to the data of the second temperature detector. When the temperatures of the first temperature detector and the second temperature detector both change, and the temperature change amplitudes are different, if the temperature change amount of the first temperature detector is greater than the temperature change amount of the second temperature detector, the control board first controls the lengths of the first telescopic rod 310 and the second telescopic rod 320 to change simultaneously. When the length of the second telescopic rod 320 reaches the length change of the second telescopic rod 320 corresponding to the temperature change amount of the second temperature detector, the control board further changes the length of the second telescopic rod 320 when controlling the length change of the first telescopic rod 310. At this time, the length change of the first telescopic rod 310 cannot reach the length change of the first telescopic rod 310 corresponding to the temperature change amount of the first temperature detector. Then, the movement of the sealing sleeve 210 on the aluminum bar 110 is jointly controlled by the first telescopic rod 310 and the second telescopic rod 320. It can be understood that the coolant entering the first chamber 112 is jointly controlled by the first temperature detector or the second temperature detector.

[0032] In one embodiment, the spoiler is a bellows 330. When the bellows 330 is extended, the diameter of the bellows 330 decreases, and when the bellows 330 is shortened, the diameter of the bellows 330 increases. In a further configuration, when the diameter of the bellows 330 changes, and the total amount of coolant entering the first chamber 112 through the first opening 113 per unit time is fixed, if the diameter of the bellows 330 increases, the channel gap that can supply the coolant flow decreases, so that the flow speed of the coolant in the first chamber 112 increases, and conversely, if the diameter of the bellows 330 decreases, the channel gap that can supply the coolant flow increases, so that the flow speed of the coolant in the first chamber 112 decreases.

[0033] In one embodiment, a support rod 340 and a fixing rod 350 are fixedly arranged in the first chamber 112, and the support rod 340 is fixedly connected to one end of the bellows 330. In a specific arrangement, the fixing rod 350 is arranged near the lower end of the aluminum bar 110, and the support rod 340 is arranged near the upper end of the aluminum bar 110, and the support rod 340 is fixedly connected to the upper end of the bellows 330. A first elastic member 360 is arranged between the fixing rod 350 and the lower end of the bellows 330, and the first elastic member 360 always has a force to drive the bellows 330 to shorten. The first elastic member 360 can be a compression spring, which is always in a compressed state, and is arranged vertically, and the lower end of the compression spring is fixedly connected to the fixing rod 350, and the upper end of the compression spring is fixedly connected to the lower end of the bellows 330, and the restoring force of the compression spring can drive the bellows 330 to shorten. In another embodiment, the first elastic member 360 can also be a hydraulic rod. The hydraulic rod always has a tendency to stretch, and when the hydraulic rod stretches, it can drive the bellows 330 to shorten.

[0034] In one embodiment, a traction rope 370 is connected between the end of the bellows 330 connected to the first elastic member 360 and the plugging sleeve 210, and the traction rope 370 is arranged around the fixing rod 350. In a specific arrangement, a first through hole is arranged on the fixing rod 350, and a second through hole connecting the first chamber 112 and the second chamber 130 is arranged on the aluminum bar 110. One end of the traction rope 370 is fixedly connected to the lower end of the bellows 330, and the middle part of the traction rope 370 slides through the first through hole and the second through hole. The other end of the traction rope 370 is connected to the plugging sleeve 210. When the plugging sleeve 210 slides along the outer wall of the aluminum bar 110, the length of the bellows 330 changes synchronously under the action of the traction rope 370.

[0035] In one embodiment, the cooling sleeve 120 includes a sleeve body 121 and two blocking covers 122, each of which is plugged into one end of the sleeve body 121, and the blocking cover 122 can block the gap between the sleeve body 121 and the aluminum bar 110. In a specific setting, an elastic claw is provided on the sleeve body 121, and a one-way rack is provided on the blocking cover 122. When the sleeve body 121 and the blocking cover 122 are plugged, the elastic claw can engage the one-way rack to prevent the sleeve body 121 and the blocking cover 122 from separating during use. The contact surfaces of the cylinder body and the blocking cover 122 are both set to rough inclined surfaces to ensure that the chamber surrounded by the cylinder body and the blocking cover 122 is in a closed state.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
