Description
Technical Field
[0001] The utility model relates to the technical field of high and low voltage distribution boxes, in particular to a high and low voltage distribution box with internal circulation heat dissipation. Background Art
[0002] As the name implies, high and low voltage distribution boxes are distribution equipment used for power distribution, control, metering and cable connection in power supply systems. Generally, power supply bureaus and substations use high voltage switch cabinets, which are then stepped down by transformers and led out to low voltage distribution boxes on the low voltage side. The low voltage distribution boxes are then led to distribution boards, control boxes and switch boxes for each power user. The equipment inside is a distribution device that is assembled into one by some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices to meet the design functional requirements.
[0003] During daily operation, the internal circuit components of the high and low voltage distribution box will generate heat due to the load, so the heat needs to be discharged in time. The traditional heat dissipation methods of high and low voltage distribution boxes are air cooling and water cooling. Air cooling is to discharge the internal heat by installing a fan at the bottom or top, while water cooling is to arrange cooling pipes inside the box to remove the surface heat of the circuit components through hot and cold contact.
[0004] However, since there are many circuit components installed inside the high and low voltage distribution cabinets, with different specifications and installation positions, it is difficult to effectively dissipate the heat of some load circuit components that generate severe heat and are located at corners by using air cooling. In addition, since circuit components need to be replaced and the layout needs to be adjusted, the originally fixed cooling pipes are also difficult to accurately contact the various load circuit components that generate severe heat, and there is also the problem of poor heat dissipation.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0022] The utility model is further described below in conjunction with embodiments. Example
[0023] Reference Figure 1-4 , which is the first embodiment of the utility model, discloses a high- and low-voltage distribution box with internal circulation heat dissipation, including a distribution box 1 and a circulating liquid pump 5 installed on the top of the distribution box 1. The circulating liquid pump 5 has a heat dissipation metal sheet to assist the cooling of the coolant. A serpentine cooling pipe 51 is arranged in the inner cavity of the distribution box 1. The two ends of the serpentine cooling pipe 51 are respectively connected to the output end and the input end of the circulating liquid pump 5. The fixed frame 2 is detachably installed in the distribution box 1. The two opposite inner frame walls of the fixed frame 2 are provided with a first slide groove 21. The front of the fixed frame 2 is provided with two second slide grooves 22 respectively connected to the corresponding first slide grooves 21. A plurality of lifting bars 3 are lifted and slidably installed in the distribution box 1. The first sliders 33 are fixedly installed at both ends of the plurality of lifting bars 3. The plurality of first sliders 33 are respectively slidably installed in the corresponding first slide grooves 21, and the plurality of A first screw 34 is threadedly installed on the first slider 33, and several first screws 34 respectively penetrate the corresponding second slide groove 22 and conflict with the fixed frame 2. Several transverse blocks 4 are respectively penetrated and slidably installed in the corresponding lifting strips 3. The length of the transverse blocks 4 is consistent with the width of the lifting strips 3, and the tops of several transverse blocks 4 are telescopically and slidably installed with extrusion blocks 46. The extrusion blocks 46 are telescopically and slidably installed in the grooves 43. When flush with the surface of the grooves 43, an extrusion force is generated on the upper hole top of the bar-shaped mounting hole 31. Several extrusion blocks 46 conflict with the corresponding lifting strips 3 respectively. A limiting stopper 47 is vertically fixedly installed at one end in the same direction of several transverse blocks 4. Several limiting stoppers 47 conflict with the serpentine cooling tube 51. The serpentine cooling tube 51 is guided to be attached to the surface of the heat load circuit component by moving the position of the limiting stopper 47. Example
[0024] Reference Figure 1-4, which is the second embodiment of the utility model. This embodiment is different from the first embodiment in that: a distribution cavity is provided on the front of the distribution box 1, and a box door 11 is rotatably installed at the cavity opening of the distribution cavity. Locking screws 23 are provided at the four corners of the fixed frame 2. The four locking screws 23 are threaded through the fixed frame 2 and threadedly installed with the distribution box 1, so that the fixed frame 2 can be easily disassembled and the heating circuit components can be repaired and replaced. Strip mounting holes 31 are provided on both sides of the lifting bars 3, and the transverse blocks 4 are slidably installed in the corresponding strip mounting holes 31 respectively. The bottom of the lower holes of the strip mounting holes 31 are provided with third sliding grooves 32, and the bottom ends of the transverse blocks 4 are fixedly installed with second sliding blocks 41. If The second sliding blocks 41 are slidably installed in the corresponding third sliding grooves 32, respectively, so that the corresponding transverse block 4 can only slide linearly back and forth in the strip mounting hole 31, and the second screws 42 are threadedly installed at one end of the transverse blocks 4 away from the corresponding limit stop rods 47, and the tops of the transverse blocks 4 are provided with grooves 43, and the ends of the second screws 42 are vertically fixed with gears 44, and one side of the gears 44 is meshed with racks 45, and the tops of the racks 45 are fixed with extrusion blocks 46. When the tops of the extrusion blocks 46 are respectively pressed and pressed against the upper hole tops of the corresponding strip mounting holes 31, the second screws 42 are just tightly attached to the ends of the corresponding transverse blocks 4, so that the extrusion blocks 46 remain fixed.
[0025] The remaining structures are the same as those of Example 1.
[0026] First, the fixing frame 2 is detachably installed in the power distribution cavity by means of four locking screws 23;
[0027] Secondly, a plurality of lifting bars 3 are moved up and down. At this time, the first sliders 33 at both ends of the lifting bars 3 slide in the corresponding first slide grooves 21 respectively, and the first screws 34 threadedly mounted on the first sliders 33 also slide up and down in the corresponding second slide grooves 22 simultaneously. When the lifting bars 3 are lifted to a specified height (the height at which the limit stopper 47 contacts the serpentine cooling tube 51), the first screws 34 at both ends are tightened respectively, so that the first screws 34 are fixed to the fixing frame 2, thereby realizing the limit fixation of the corresponding lifting bars 3.
[0028] Finally, slide the corresponding transverse blocks 4 respectively. At this time, the transverse blocks 4 and the second screws 42 slide synchronously, and the second slider 41 at the bottom of the transverse block 4 will assist in sliding in the corresponding third slide groove 32 to ensure that the transverse block 4 can only move linearly back and forth. When the transverse block 4 slides to the specified position (the position where the limit lever 47 contacts the serpentine cooling tube 51), tighten the second screws 42 at one end of the transverse block 4 to drive the corresponding gear 44 to rotate, which in turn drives the corresponding rack 45 to rise and slide, pushing the extrusion block 46 to squeeze and contact the upper hole top of the strip mounting hole 31, which limits the lateral position of the transverse block 4 and fixes it. Finally, the limit lever 47 can make the serpentine cooling tube 51 contact and attach to the surface of the heat-generating load circuit component, thereby realizing accurate and efficient internal circulation liquid cooling.
[0029] 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 replace some of the technical features therein by equivalents. 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.
