Description

Technical Field

[0001] The invention relates to the technical field of current probes, and in particular to an efficient heat dissipation current probe for an embedded cooling system. Background Art

[0002] When the current probe is working, it needs to pass current to detect the current parameters in the circuit, and a certain amount of heat will be generated in this process; this is because when the current flows through the probe, resistance will be generated, and the resistance will cause energy conversion, and part of the electrical energy will be converted into heat energy, thereby causing the probe to heat up; this heating phenomenon is more obvious when the current is large or the probe resistance is large. In order to reduce the heating problem of the probe during operation, natural heat dissipation or forced heat dissipation is usually adopted. Among them, forced heat dissipation is through an external driving force, such as using a fan or blower, to accelerate air flow and enhance the convective heat transfer effect, thereby improving the heat dissipation efficiency. However, due to the influence of the working environment temperature, the convective heat transfer effect of relying on external air is limited, and the heat dissipation effect is not as good as the traditional water cooling method.

[0003] After a traditional current probe is embedded in a cooling system, in order to cool the needle in time, the heat exchanger in the cooling system needs to be embedded and installed inside the needle, and the heat exchanger connector extends to the outside of the needle to facilitate connection to the cooling system; however, the embedding of the heat exchanger requires connecting and disconnecting the heat exchanger from the cooling system when assembling and disassembling the needle with the needle tube, which makes the probe assembly and disassembly operations more troublesome.

[0073] Principle and advantages of embedded cooling system efficient heat dissipation current probe:

[0074] First, the heat exchanger 24 is preset inside the needle tube 21, and the two ends of the heat exchanger 24 are placed outside the needle sleeve 1 through the slider 23. After the needle tube 21 is installed inside the needle sleeve 1 through the slider 23, the two ends of the heat exchanger 24 can be connected to the external cooling system by connecting with the catheter 42. By connecting the two ends of the heat exchanger 24 to the cooling system, the cooling system inputs the coolant into the heat exchanger 24. Finally, the needle sleeve 1 is installed on the test module through the plugging head 18 and can be used. When the needle tube 21 and the probe 22 are heated during use, the temperature is transferred to the heat exchanger through the thermal grease inside the needle tube 21. On the outside of the hot element 24, the coolant inside the heat exchange element 24 absorbs the heat and transfers it to the outside of the needle tube 21, so that the needle tube 21 can be directly cooled; and in the working process of the needle tube 21, the spring 17 inside the needle sleeve 1 applies elastic force to the conductive sheet 16, so that the conductive sheet 16 fits tightly against the top of the conductive sheet 210. When the needle tube 21 passes the current, the current flows through the threaded cap 28 to the conductive sheet 210 on the top of the guide core 29, so that the current signal flows to the conductive sheet 16 on the top of the conductive sheet 210, and finally guides to the test equipment through the wire 19 outside the conductive sheet 16.

[0075] The advantages are that the heat is absorbed and transferred by embedding the heat exchanger 24 inside the needle tube 21, thereby achieving the effect of cooling and dissipating the heat of the needle tube 21. The heat exchange effect of the heat exchanger 24 is less affected by the working environment temperature, which can ensure that each needle tube 21 on the module can be cooled in time and the heat dissipation is more uniform. After the heat exchanger 24 is embedded, the heat exchanger 24 can be assembled and disassembled together with the needle tube 21 through the slider 23 by changing the assembly and disassembly method of the needle head 2 and the needle sleeve 1. After the needle tube 21 and the heat exchanger 24 are disassembled together, the needle tube 21 can be replaced separately by further disassembling the heat exchanger 24 and the needle tube 21, thereby reducing the loss caused by the wear and tear of the needle tube 21.

[0076] When assembling the needle tube 21 of the limiting component 3 in the high-efficiency heat dissipation current probe of the embedded cooling system of the present application, the slider 23 is inserted from the bottom of the needle sleeve 1 into the inner side of the slot 11, and then the needle tube 21 is rotated to drive the slider 23 to slide to the inner side of the transverse groove 12. When the slider 23 passes under the stopper 31, the stopper 31 rotates around the pin shaft 15 under the push of the slider 23 until it slides into the inner side of the longitudinal groove 13 and is pushed upward. At this time, the stopper 31 continues to rotate upward, so that the slider 23 moves to the top of the limiting component 3, and the slider 23 is free from the obstruction of the stopper 31. At this time, the stopper 31 on one side The inclined surface 1 312 is pressed against the outer side of the inclined surface 2 332, and the counterweight block 32 is located on the side of the block 31 close to the longitudinal groove 13, so that the block 31 automatically rotates downward under the action of the counterweight block 32, so that the vertical surface 1 311 on one side of the block 31 rotates to fit with the vertical surface 2 331, and at this time, the bottom of the inclined surface 1 312 is flush with one side of the longitudinal groove 13, so that when the slider 23 slides on the inner side of the longitudinal groove 13, the slider 23 is prevented from entering the inner side of the transverse groove 12 and getting stuck under the obstruction of the block 31, and at this time, the inclined surface 3 333 on one side of the locking block 33 is located on the outer side of the elastic sheet 37;

[0077] When the needle tube 21 is to be disassembled, the needle tube 21 is pushed upward, so that the needle tube 21 pushes the conductive sheet 16 upward through the conductive sheet 210 to compress the spring 17. After the conductive sheet 16 is pushed a certain distance, the bracket 35 is pushed upward by the push rod 110, so that the bracket 35 drives the locking block 33 to move upward to the top of the elastic sheet 37 through the slide bar 34, so that the elastic sheet 37 supports the bottom of the locking block 33. At this time, the locking block 33 releases the obstruction of the stopper 31, and then the slider 23 can be rotated to slide toward the inside of the horizontal groove 12 for disassembly; and the slider 23 is moved upward by the slide bar 34. When passing the bottom of the inclined surface 312, the slider 23 gradually squeezes the upward curved side of the elastic sheet 37 to continue to bend upward, thereby releasing the support for the locking block 33. At this time, the locking block 33 moves downward and is located on the outside of the vertical surface 311, and the inclined surface 333 does not contact the elastic sheet 37. When the slider 23 disengages from the inner side of the transverse groove 12, the stopper 31 automatically rotates downward and resets, and the locking block 33 moves downward to follow and move, so that the locking block 33 and the vertical surface 311 are automatically reset. After the reset, the stopper 31 and the locking block 33 will return to the initial state to facilitate subsequent assembly.

[0078] It is worth mentioning that the above disassembly and assembly method has the following advantages:

[0079] Advantage 1: The slider 23 is slidably assembled along the slot 11, the transverse groove 12 and the longitudinal groove 13 to facilitate positioning of the needle tube 21 and the center of the needle sleeve 1, and after the slider 23 slides into the longitudinal groove 13, it is automatically limited by the limit assembly 3 to prevent the slider 23 from sliding into the inner side of the transverse groove 12 during operation, making it more convenient to use and assemble, and ensuring that the two ends of the heat exchanger 24 are always located outside the needle sleeve 1 and connected to the cooling system.

[0080] Advantage 2: By pushing the needle tube 21 upward, the locking block 33 can be triggered to move, so that the locking block 33 releases the limiting effect on the stopper 31. When the slider 23 is disassembled, the stopper 31 can be pushed to rotate and enter the inner side of the transverse groove 12 to facilitate the disassembly of the needle tube 21.

[0081] Advantage three, when the slider 23 passes under the block 31 during the disassembly process, the elastic sheet 37 is squeezed by the block 31 to release the limit on the locking block 33, so that the locking block 33 moves downward to the outside of the vertical surface 311, and when the block 31 is rotated downward to reset, the locking block 33 can automatically move downward, so that the limit assembly 3 can be automatically reset after disassembly, which is convenient for subsequent disassembly and assembly operations.

[0082] In practical applications, the connection method between the heat exchange element 24 and the cooling system is as follows:

[0083] First, when the slider 23 is inserted into the inner side of the slot 11, the conductive sheet 210 above the slider 23 starts to push the conductive sheet 16 to squeeze the spring 17. At this time, the waterproof groove 4 outside the heat exchanger 24 and the top cover 41 outside the conductive sheet 16 are tightly connected by magnetic adsorption. When the slider 23 slides toward the inner side of the longitudinal groove 13, the slider 23 drives the connector 25 located inside the waterproof groove 4 to approach the butt joint 43. At this time, the resistance brought by the butt joint 43 to the sliding of the slider 23 can be felt. The butt joint 43 can be made of rubber or The connecting head 25 is made of materials such as silicone. As the slider 23 continues to slide toward the inside of the longitudinal groove 13, the connecting head 25 gradually squeezes the butt joint 43. Since the butt joint 43 has the ability to deform, when the slider 23 is located on the inside of the longitudinal groove 13, the connecting head 25 always maintains a pressed state with the butt joint 43. At this time, the heat exchange component 24 and the butt joint 43 maintain a butt joint state in the horizontal direction, and the waterproof groove 4 and the top cover 41 attract each other in the vertical direction to ensure stability in the vertical direction, so as to facilitate the heat exchange component 24 to be connected to the external cooling system through the conduit 42.

[0084] It is worth mentioning that the above disassembly and assembly method has the following advantages:

[0085] Advantage 1: When the needle tube 21 is installed, the heat exchange element 24 can be automatically docked with the catheter 42, so that the heat exchange element 24 embedded in the needle tube 21 can be connected to the external cooling system.

[0086] Advantage 2: After docking, the docking point is protected by the waterproof groove 4 and the top cover 41 to prevent leakage during use from damaging the test piece, thereby ensuring safety of use. In addition, the cooperation between the waterproof groove 4 and the top cover 41 does not affect the assembly and disassembly of the slider 23, making it more convenient to use.

[0087] Advantage three: by setting a conductive pin 44 at the bottom of the top cover 41, leakage detection is performed inside the waterproof tank 4. When leakage occurs, the coolant will conduct the two conductive pins 44, causing the external alarm system to issue a leakage alarm, thereby improving safety in use.

[0088] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
