Description

Technical Field

[0001] The invention belongs to the technical field of distribution boxes, and in particular relates to an electric power construction distribution box with temperature and humidity sensors. Background Art

[0002] Power construction distribution boxes play a vital role in the manufacturing process of power electronic components such as metal oxide semiconductor field effect transistors (MOSFETs), insulated gate bipolar transistors (IGBT) chips and modules. These components are the core components of modern power electronic systems and are widely used in power conversion, motor drive, renewable energy access and other fields. During the manufacturing process, power construction distribution boxes are mainly used to provide a stable and reliable power supply and ensure the safety and controllability of the production environment.

[0003] At present, when the wires enter the power distribution box through the wire holes for the installation of components, there is a large gap between the wires and the wire holes. This causes a large amount of dust and impurities to enter the distribution box during the construction process, which easily causes internal dust accumulation and adheres to the outer surface of the equipment, causing uneven heat dissipation of the equipment and components in the distribution box and even static electricity fire. In addition, moisture in the air can also enter the distribution box through the gaps, accelerating the aging of internal components and even causing short circuit fires. Summary of the invention

[0004] The object of the present invention is to provide an electric power construction distribution box with a temperature and humidity sensor to solve the problems raised in the above-mentioned background technology.

[0006] Preferably, the cooling and dehumidification mechanism includes an air inlet bend pipe, a filter bag is fixedly connected to the bottom of the air inlet bend pipe, a water-locking cotton is provided on the curved surface of the filter bag, a liquid inlet bend pipe is provided inside the air inlet bend pipe, and a plurality of connecting columns are fixedly connected between the air inlet bend pipe and the liquid inlet bend pipe.

[0007] Preferably, the heat dissipation mechanism comprises a plurality of heat dissipation shells, a plurality of connecting pipes are fixedly connected between two adjacent heat dissipation shells, and a water outlet pipe is fixedly connected to the top of the uppermost heat dissipation shell.

[0008] Preferably, the outer fixing ring is fixedly connected to the box body, the inner fixing ring is fixedly connected to the box body, the sealing gasket is slidably connected to the liquid shell, the threaded rod is threadedly connected to the liquid shell, the connecting seat is fixedly connected to the box body, and the movable plate is clamped to the back side of the box body.

[0009] Preferably, the top end of the air inlet bend is connected to the rectangular tube, the water-locking cotton is movably installed at the bottom of the rectangular shell, the liquid inlet bend is located at the center of the air inlet bend, the connecting column is fixedly connected to the rectangular shell, the upper end of the liquid inlet bend is connected to the liquid inlet of the liquid pump, and the lower end of the liquid inlet bend is connected to the bottom heat dissipation shell.

[0010] Preferably, the plurality of heat dissipation shells are fixedly connected to the back side of the box body, and the upper end of the water outlet pipe is connected to the liquid outlet of the liquid pump.

[0011] Preferably, the elastic membrane is made of elastic material, the interior of the liquid shell is filled with hydraulic oil, and the interiors of the plurality of heat dissipation shells and the liquid inlet elbows are filled with coolant.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The present invention installs electronic components on multiple connection seats, and the connected wires pass through the wire holes into the interior of the box. Then, the threaded rod is rotated so that the threaded rod pushes the push block and the sealing gasket to move backward. During the process, the space behind the sealing gasket becomes smaller, so that the hydraulic oil squeezes the elastic film to deform, and finally the elastic film is tightly fitted with the surface of the wire, so that the interior of the distribution box forms a relatively closed space, thereby solving the problem that a large amount of dust and impurities enter the interior of the distribution box during the construction process, which easily causes internal dust accumulation and adheres to the outer surface of the equipment, resulting in uneven heat dissipation of equipment and components in the distribution box and even static electricity fire.

[0014] 2. The present invention works by driving the motor, which will drive the fan blades to rotate, thereby sucking the hot air inside the box into the interior of the rectangular tube through the intake pipe, and finally entering the air intake elbow. Since the temperature of the coolant inside the liquid inlet elbow is relatively low, it will absorb the heat in the hot air inside the air intake elbow. When the temperature of the coolant inside the liquid inlet elbow is relatively high, the liquid pump will work to pump the higher coolant inside the liquid inlet elbow into the uppermost heat dissipation shell, and transfer the heat brought out to the atmosphere, and the cooled air will be discharged from the filter bag. The filter bag will filter the dust in the gas inside the filter bag, and the filtered gas will flow upward through the water-locking cotton and finally be discharged through the air outlet, thereby cooling the internal environment of the box.

[0015] 3. The present invention passes gas with high humidity into the air inlet elbow, so that it contacts with coolant with low temperature inside the liquid inlet elbow, which condenses into water droplets on the outer wall of the liquid inlet elbow, slides to the bottom of the liquid inlet elbow, and finally drips into the inside of the filter bag. When the condensed gas passes through the filter bag and contacts the dust on the inner wall of the filter bag, the water molecules in the gas will form droplets attached to these dust particles, thereby further dehumidifying, thereby solving the problem of high humidity inside the distribution box, accelerating the aging of internal components, and even causing short circuit and fire.

Its function is to install electronic components on multiple connecting seats 14, and the connected wires pass through the wire holes 5 into the box 1 The inside of the distribution box is then rotated, and the threaded rod 11 is made to push the pushing block 9 and the sealing gasket 10 to move backward. During the process, the space behind the sealing gasket 10 becomes smaller, so that the hydraulic oil will squeeze the elastic membrane 7 to deform, and finally the elastic membrane 7 is tightly fitted with the surface of the wire, so that the inside of the distribution box is formed into a relatively closed space, thereby solving the problem that a large amount of dust and impurities enter the distribution box during the construction process, which is easy to cause internal dust accumulation and adhere to the outer surface of the equipment, resulting in uneven heat dissipation of equipment and components in the distribution box and even static electricity fire.

[0025] Among them, the cooling and dehumidification mechanism 20 includes an air intake elbow 201, a filter bag 202 is fixedly connected to the bottom of the air intake elbow 201, a water-locking cotton 203 is arranged on the curved surface of the filter bag 202, a liquid inlet elbow 204 is arranged inside the air intake elbow 201, and a plurality of connecting columns 205 are fixedly connected between the air intake elbow 201 and the liquid inlet elbow 204, whose function is to pass the gas with higher humidity into the air intake elbow 201 so that it contacts with the coolant with lower temperature inside the liquid inlet elbow 204, and condense into water droplets on the outer wall of the liquid inlet elbow 204, slide to the bottom of the liquid inlet elbow 204, and finally drip into the inside of the filter bag 202. When the condensed gas passes through the filter bag 202 and contacts with the dust on the inner wall of the filter bag 202, the water molecules in the gas will form droplets with the dust particles attached to these dust particles, thereby further dehumidifying, thereby solving the problem that the humidity inside the distribution box is high, the aging of internal components is accelerated, and even a short circuit and fire are caused.

[0026] Among them, the heat dissipation mechanism 22 includes multiple heat dissipation shells 221, multiple connecting pipes 222 are fixedly connected between two adjacent heat dissipation shells 221, the top of the uppermost heat dissipation shell 221 is fixedly connected with a water outlet pipe 223, the top of the air intake elbow 201 is connected to the rectangular tube 16, the water locking cotton 203 is movably installed at the bottom of the rectangular shell 12, the liquid inlet elbow 204 is located at the center of the air intake elbow 201, the connecting column 205 is fixedly connected to the rectangular shell 12, the upper end of the liquid inlet elbow 204 is connected to the liquid inlet of the liquid pump 21, and the lower end of the liquid inlet elbow 204 is connected to the lowermost heat dissipation shell 221, multiple heat dissipation shells 221 are fixedly connected to the back side of the box body 1, the upper end of the water outlet pipe 223 is connected to the liquid outlet of the liquid pump 21, the elastic membrane 7 is made of elastic material, the interior of the liquid shell 6 is filled with hydraulic oil, and the interiors of multiple heat dissipation shells 221 and the liquid inlet elbow 204 are filled with cooling Liquid, its function is to work through the driving motor 18, and the driving motor 18 will drive the fan blades 19 to rotate, so as to suck the hot air inside the box body 1 into the inside of the rectangular tube 16 through the suction pipe 15, and finally enter the air intake elbow 201. Since the temperature of the coolant inside the liquid inlet elbow 204 is relatively low, it will absorb the heat in the hot air inside the air intake elbow 201.

[0027] Working principle:

[0028] When the present invention is used, the electronic components are mounted on the plurality of connection seats 14, the connected wires pass through the wire holes 5 into the interior of the box 1, and then the threaded rod 11 is rotated so that the threaded rod 11 pushes the push block 9 and the sealing gasket 10 to move backwards. During the process, the space behind the sealing gasket 10 becomes smaller, so that the hydraulic oil squeezes the elastic film 7 to produce deformation, and finally the elastic film 7 is closely fitted to the surface of the wire;

[0029] Then, the sealing cover 2 is installed on the front of the box 1, and the electronic components will work inside the box 1. During the process, the temperature sensor 3 and the humidity sensor 4 will monitor the humidity and temperature inside the box 1. When the internal temperature and humidity of the box 1 are high, the drive motor 18 is operated through the existing controller, and the drive motor 18 will drive the fan blades 19 to rotate, so that the hot air inside the box 1 is sucked into the interior of the rectangular tube 16 through the suction pipe 15, and finally enters the air intake elbow 201. Since the coolant temperature inside the liquid intake elbow 204 is low, It absorbs the heat in the hot air inside the air inlet elbow 201. When the temperature of the coolant inside the liquid inlet elbow 204 is high, the liquid pump 21 works to pump the coolant inside the liquid inlet elbow 204 into the top heat dissipation shell 221, and transfers the heat brought out to the atmosphere. The cooled air will be discharged from the filter bag 202. The filter bag 202 will filter the dust in the gas inside the filter bag 202. The filtered gas passes through the water-locking cotton 203 and flows upward, and is finally discharged through the air outlet 13, thereby cooling the internal environment of the box body 1.

[0030] When the hot air entering the air inlet elbow 201 has a high humidity, it will come into contact with the coolant with a lower temperature inside the liquid inlet elbow 204, and condense into water droplets on the outer wall of the liquid inlet elbow 204, slide to the bottom of the liquid inlet elbow 204, and finally drip into the inside of the filter bag 202. When the condensed gas passes through the filter bag 202 and comes into contact with the dust on the inner wall of the filter bag 202, the water molecules in the gas will form droplets attached to these dust particles, thereby further dehumidifying, and the water-locking cotton 203 will condense the outer wall of the liquid inlet elbow 204 into water droplets and the water molecules will attach to the dust particles to form droplets for absorption, thereby preventing water from volatilizing. When there are large dust clusters inside the filter bag 202 or the water-locking cotton 203 absorbs a lot of water, the filter bag 202 and the water-locking cotton 203 can be replaced by opening the movable plate 23.
