Abstract
Description
Technical Field
[0001] This utility model relates to the field of terminal box technology, and in particular to an anti-condensation terminal box. Background Technology
[0002] Terminal boxes are one of the most important pieces of equipment in substations, providing control and power supplies for the equipment. Their safety and reliability directly affect the safe operation of the substation. A significant problem with some outdoor terminal boxes is that condensation easily forms inside them when the temperature drops and humidity is high. This condensation adheres to the inner walls of the terminal box, and when it accumulates, it drips down, damaging not only the internal components but also affecting the operation of the entire circuit.
[0003] Traditional terminal boxes have multiple ventilation holes on both sides of the box for heat dissipation. The airflow inside the box is accelerated by a fan or air convection circulation. This inevitably brings humid air into the box. When the temperature inside the box is lower than the outside temperature, the water vapor in the high-humidity air will condense into water droplets when it comes into contact with the cold box surface, which will corrode electrical components and affect the normal operation of the equipment. Therefore, the applicant has made a useful design and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the traditional terminal box design and provide a product that prevents condensation and controls temperature rise.
[0005] A terminal box with anti-condensation features includes a box body and a door. A first sealing strip is provided between the box body and the door. One side of the box body is provided with a protective cover. The lower part of the protective cover has several air inlets, and the upper part of the protective cover has several heat dissipation holes. A mounting plate is provided inside the box body. The mounting plate has a heat-conducting part that passes through the box body. A second sealing strip is provided between the heat-conducting part and the side wall of the box body. The heat-conducting part has a heat dissipation plate and is disposed inside the protective cover. The heat dissipation plate has several equally spaced heat dissipation fins from left to right. The heat dissipation fins have several detachable metal parts from bottom to top. The metal parts have several heat dissipation sections and are disposed on both sides of the heat dissipation fins.
[0006] Preferably, the door has an annular protrusion, and the first sealing strip is fixed to the outer wall of the protrusion.
[0007] Preferably, one end of the box body is provided with a cavity to accommodate the protrusion, the entrance of the cavity is provided with an inclined surface, the back of the box body is provided with a through hole for the heat-conducting part to pass through, the bottom of the box body is provided with a box cavity, and a solid desiccant is provided in the box cavity.
[0008] Preferably, the mounting plate has a plurality of equally spaced first mounting holes.
[0009] Preferably, the metal part has fixing portions on both sides, the fixing portions have at least two second mounting holes, and the heat dissipation portion is disposed in the fixing portions.
[0010] Preferably, the heat sink has grooves on both sides for accommodating the fixing part, and the grooves have through holes corresponding to the second mounting holes.
[0011] Preferably, the outer walls of the first sealing strip and the second sealing strip are provided with protruding pockets, which respectively abut against the cavity and the through hole. Beneficial effects
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] (1) This utility model strengthens the sealing between the door and the body by using the first sealing strip and strengthens the sealing between the heat dissipation part and the body by using the second sealing strip. The above design prevents external humid air and dust from entering the body, prevents condensation from forming inside the body, and avoids condensation from affecting the normal operation of the equipment, so that the product has the advantage of anti-condensation.
[0014] (2) In this utility model, the temperature generated during the operation of the equipment is absorbed by the mounting plate and transferred to the heat sink and metal parts through the heat conduction part. When the air comes into contact with the heat sink and heat dissipation part and heat exchange occurs, the air is heated and sealed, becomes smaller and rises and is discharged from the heat dissipation hole. The cold air outside enters through the ventilation hole to replenish the air in the protective cover, thereby forming an air convection circulation, thereby reducing the temperature inside the box and giving the product the advantage of controlling the temperature rise.

[0033] Reference example Figures 1 to 7 A terminal box for preventing condensation includes a box body 1 and a door 2. A first sealing strip 3 is provided between the box body 1 and the door 2. One side of the box body 1 is provided with a protective cover 4. The lower part of the protective cover 4 is provided with several air inlets 41, and the upper part of the protective cover 4 is provided with several heat dissipation holes 42. A mounting plate 5 is provided inside the box body 1. The mounting plate 5 is provided with a heat-conducting part 51 and passes through the box body 1. A second sealing strip 6 is provided between the heat-conducting part 51 and the side wall of the box body 1. The heat-conducting part 51 is provided with a heat dissipation plate 7 and is disposed inside the protective cover 4. A plurality of equally spaced heat sinks 71 are provided from left to right. A plurality of detachable metal parts 8 are provided from bottom to top on the heat sinks 71. The metal parts 8 are provided with a plurality of heat dissipation sections 81 and are provided on both sides of the heat sinks 71. The sealing between the door 2 and the housing 1 is strengthened by the first sealing strip 3, and the sealing between the heat dissipation section 81 and the housing 1 is strengthened by the second sealing strip 6. The above design prevents external humid air and dust from entering the housing 1, prevents condensation from forming inside the housing 1, and avoids condensation from affecting the normal operation of the equipment.
[0034] It is worth mentioning that the door 2 is provided with an annular protrusion 21, and the first sealing strip 3 is fixed on the outer wall of the protrusion 21. When the protrusion 21 is embedded in the cavity 11, it forms a labyrinth-type sealing structure to improve the sealing performance.
[0035] It is worth mentioning that one end of the box body 1 is provided with a cavity 11 to accommodate the protrusion 21, and the entrance of the cavity 11 is provided with an inclined surface 12. The back of the box body 1 is provided with a through hole 13 for the heat conduction part 51 to pass through. The bottom of the box body 1 is provided with a box cavity 14, and a solid desiccant 15 is provided in the box cavity 14. The solid desiccant 15 can be anhydrous calcium carbonate, silica gel, or activated carbon, which adsorbs the residual moisture in the box body 1 and further prevents condensation from forming in the box body 1.
[0036] It is worth mentioning that the mounting plate 5 is provided with several equally spaced first mounting holes 52, which are connected and fixed to the equipment;
[0037] It is worth mentioning that the metal part 8 has a fixing part 82 on both sides, the fixing part 82 has at least two second mounting holes 83, the heat dissipation part 81 is provided on the fixing part 82, and fasteners such as bolts and fastening screws are provided in the second mounting holes 83 to connect and fix the fixing part 82 to the groove 72.
[0038] It is worth mentioning that the heat sink 71 has grooves 72 on both sides to accommodate the fixing part 82. The grooves 72 have through holes 73 corresponding to the second mounting hole 83. Since the box 1 forms a sealed space, in order to exhaust the temperature generated during the operation of the equipment to the outside, the mounting plate 5 absorbs the temperature generated during the operation of the equipment and conducts heat to the heat sink 7 and metal parts 8 through the heat conduction part 51. When the air comes into contact with the heat sink 71 and the heat dissipation part 81 and generates heat exchange, the air is heated and the seal becomes smaller and rises and is discharged from the heat dissipation hole 42. The cold air outside enters from the ventilation hole to replenish the air in the protective cover 4, thereby forming an air convection circulation, thereby reducing the temperature inside the box 1. The heat dissipation part 81 increases the contact area with the air, further improving the heat dissipation effect under natural heat dissipation conditions.
[0039] It is worth mentioning that the outer walls of the first sealing strip 3 and the second sealing strip 6 are provided with protruding bladders 9, which respectively abut against the cavity 11 and the through hole 13. The bladders 9 ensure that the first sealing strip 3 and the second sealing strip 6 are sealed and fitted against the side walls of the cavity 11 and the through hole 13, respectively, preventing external air from seeping in.
[0040] The above design scheme enables the product to achieve the advantages of preventing condensation and controlling temperature rise.
[0041] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
