[0034] The integrated power supply housing 1 is a rectangular box as a whole. The integrated power supply housing 1 includes a plurality of cabinet doors 11 hinged to the integrated power supply housing 1. The integrated power supply housing 1 can be opened through the cabinet doors 11 for the installation and maintenance of the power supply and the dehumidification and heat dissipation module 2.

The ventilation component 6 is installed on the installation box 3 and the installation box cover plate 4. The compressor 7 is arranged outside the installation box 3. The compressor 7 is connected to the dehumidification and heat dissipation component 5 inside the installation box 3. The refrigerant in the compressor 7 circulates through the condenser tube 54 and is injected into the dehumidification and heat dissipation component 5 to dehumidify and cool the hot air inhaled into the installation box 3.

[0037] The main function of the installation box 3 is to serve as a carrier for the installation of the dehumidification and heat dissipation component 5 and the ventilation component 6. The dehumidification and heat dissipation component 5 and the ventilation component 6 are installed inside the installation box 3.

[0038] The main function of the installation box cover plate 4 is to close the opening on the front of the installation box 3. At the same time, the intake fan 61 in the ventilation component 6 is also installed on the installation box cover plate 4.

[0039] The main function of the ventilation component 6 is to suck the high-temperature and high-humidity air accumulated in the integrated power supply housing 1 into the dehumidification and heat dissipation component 5 of the dehumidification and heat dissipation module 2, and at the same time release the dried low-temperature air back into the integrated power supply housing 1.

[0040] The main function of the dehumidification and heat dissipation component 5 is to cool down and condense and dehumidify the high-temperature and high-humidity air accumulated in the integrated power supply housing inhaled by the ventilation component 6, thereby realizing the cooling and dehumidification of the integrated power supply device and improving the service life of the equipment in the integrated power supply device.

[0041] The compressor 7 is an important part of the dehumidification and heat dissipation module 2.

[0042] Definition: In this embodiment, taking the plane on which the integrated power supply housing 1 is placed as a reference, the direction from the integrated power supply housing 1 to the placement surface is the lower direction, and the direction opposite to it is the upper direction. The side of the integrated power supply housing 1 where the cabinet door 11 is installed is the front, and the other side opposite to it is the back.

[0043] As Figure 2 and 3 shown, the installation box 3 includes an installation cavity 31 and a water storage tank 32. The water storage tank 32 is arranged on the lower surface of the installation box 3 and is communicated with the installation cavity 31 inside the installation box 3. The condensed water discharged from the dehumidification and heat dissipation component 5 in the installation cavity 31 falls into the lower water storage tank 32.

[0044] The installation box 3 is a hollow box with a rectangular cross-section. The front of the installation box 3 is open, and a cavity for installing the dehumidification and heat dissipation component 5 is left inside the installation box 3. This cavity is named the installation cavity 31, and the dehumidification and heat dissipation component 5 is installed in this cavity.

[0045] For the convenience of installing the water storage tank 32, a rectangular hole communicating with the installation cavity 31 is opened on the lower surface of the installation box 3. The water storage tank 32 is fixed on the installation box 3 by screws and is communicated with the installation cavity 31 through the rectangular hole.

[0046] The water storage tank 32 is an overall hollow conical cover. The upper end of the water storage tank 32 with a larger size is fixed on the installation box 3 by screws, and a drain pipe 35 communicated with the water storage tank 32 is welded at the lower end of the water storage tank 32 with a smaller size. The condensed water falling into the water storage tank 32 is discharged to the outside through the drain pipe 35.

[0047] To facilitate the installation of the exhaust fan 62, on two sides of the installation box 3, circular exhaust holes 33 penetrating the installation box 3 are vertically opened on the sides of the installation box 3. To improve the exhaust effect, two exhaust holes 33 are evenly opened on each side of the installation box 3. Four exhaust fans 62 are installed on both sides of the installation box 3 by screws.

[0048] To facilitate the fixation of the installation box 3, a rectangular fixing plate 34 is welded on the upper end face of the installation box 3 and the side face of the water storage tank 32. Installation holes are opened on the fixing plate 34, and the installation box 3 can be fixed into the integrated power supply housing 1 by screws.

[0049] To facilitate the installation of the compressor 7, a rectangular compressor mounting plate 36 is welded on another side face of the water storage tank 32. The size of the compressor mounting plate 36 is larger than that of the fixing plate 34. Installation holes are opened on the compressor mounting plate 36, and the compressor 7 can be connected to the installation box 3 through the installation holes.

[0050] As Figure 2 、 4 As shown in 8, the installation box cover plate 4 is a plate with a certain thickness and a rectangular cross-section. The installation box cover plate 4 is fixed to the open end on the front of the installation box 3 by screws to enclose the installation box 3.

[0051] To facilitate the installation of the intake fan 61, two circular intake holes 41 are spaced apart on the surface of the installation box cover plate 4. The intake fan 61 in the ventilation assembly 6 corresponds to the size of the intake holes 41. At the same time, on the surface of the installation box cover plate 4, a rectangular intake fan mounting ring 42 protrudes outward perpendicular to the installation box cover plate 4. The width of the intake fan mounting ring 42 is slightly larger than the width of the intake fan 61, and the length of the intake fan mounting ring 42 is slightly larger than twice the length of the intake fan 61. Two intake fans 61 are placed in this intake fan mounting ring 42.

[0052] To prevent dust in the integrated power supply housing 1 from entering the dehumidification and heat dissipation module 2 and affecting the heat dissipation and dehumidification effect of the dehumidification and heat dissipation component 5 in the dehumidification and heat dissipation module 2, a filter screen 44 is also provided on the intake fan mounting ring 42.

[0053] To facilitate the installation of the filter screen 44, on the four inner side faces of the intake fan mounting ring 42, a rectangular filter screen slot 43 is recessed at one end close to the front, and the filter screen slot 43 on one of the side faces communicates with the outside of the intake fan mounting ring 42. The filter screen 44 can be inserted into the filter screen slot 43 inside the intake fan mounting ring 42 from here. Such a setting facilitates the installation, disassembly and cleaning of the filter screen 44 and is convenient to use.

[0054] As Figure 2 、 5As shown in FIGS. 6, 7 and 9, the dehumidifying and heat-dissipating component 5 includes an evaporator 51, a condenser 52 and a mounting bracket 53. The evaporator 51 and the condenser 52 are connected by a capillary tube 56, and the condenser 52 and the evaporator 51 are mounted in the mounting cavity 31 in the mounting box 3 through the mounting bracket 53.

[0055] The evaporator 51 includes a condensation tube 54 for refrigerant circulation and heat-dissipating fins 55 mounted on the condensation tube 54. The condensation tube 54 is a circular copper tube distributed in an "S" shape. The condensation tube 54 is also called a copper tube in the industry. One end of the condensation tube 54 is connected to the capillary tube 56, and the other end is connected to the copper tube on the compressor 7.

[0056] In order to improve the heat dissipation effect and increase the contact surface of the condensation tube 54, a heat-dissipating groove 57 with a rectangular cross-section is recessed inside the condensation tube 54 along the extending direction of the condensation tube 54. The heat-dissipating groove 57 is opened along the length direction of the condensation tube 54. Through the heat-dissipating groove 57, the contact area between the condensation tube 54 and the refrigerant can be increased, thereby increasing the refrigeration effect.

[0057] In order to facilitate the rapid condensation of moisture in the air inside the integrated power machine case 1, a plurality of heat-dissipating fins 55 are arranged in parallel along the extending direction of the condensation tube 54 on the condensation tube 54. The heat-dissipating fins 55 are rectangular thin sheets made of aluminum foil, and a hydrophilic layer is coated on the surface of the heat-dissipating fins 55. Condensed water will quickly spread on the heat-dissipating fins 55 and will not condense into water droplets, increasing the heat exchange area and accelerating the refrigeration and heating speed.

[0058] The function of the heat-dissipating fins 55 is to conduct the temperature of the heat-dissipating groove 57 and increase the contact area with the air. After the hot air encounters the cold heat-dissipating fins 55, the moisture in the air will condense on the heat-dissipating fins 55 and fall into the lower water storage tank 32, and then be discharged to the outside through the drain pipe 35 to complete dehumidification.

[0059] The condenser 52 is the same as the evaporator 51, including a condensation tube 54 distributed in an "S" shape and heat-dissipating fins 55 mounted on the condensation tube 54. One end of the condensation tube 54 on the condenser 52 is connected to the capillary tube 56, and the other end is connected to the copper tube on the compressor 7. The capillary tube 56 is spiral and is made of copper tube as a whole. The diameter of the capillary tube 56 is smaller than the diameter of the condensation tube 54. The capillary tube 56 is located at the interval between the evaporator 51 and the condenser 52. The high-temperature and high-pressure gas discharged by the compressor 7 is cooled by the condenser 52 and then throttled into a low-temperature and low-pressure liquid by the capillary tube 56, and then flows into the evaporator 51 for heat dissipation and dehumidification.

[0060] In order to facilitate the installation of the evaporator 51 and the condenser 52, mounting brackets 53 are provided on the evaporator 51 and the condenser 52, and the evaporator 51 and the condenser 52 are fixed in the mounting cavity 31 through the mounting brackets 53.

[0061] The cross-section of the mounting bracket 53 is in the shape of a "work" character. Mounting holes penetrating through the crossbeams are provided on the upper and lower crossbeams of the mounting bracket 53. The mounting bracket 53 is fixed in the mounting cavity 31 through the mounting holes by using screws. A limiting port 58 penetrating through the vertical beam is provided perpendicularly to the vertical beam on the vertical beam in the middle of the mounting bracket 53. The limiting port 58 is provided on both sides of the mounting bracket 53, and there is a certain distance between the limiting ports 58 on both sides. The condensing pipes 54 in the evaporator 51 and the condenser 52 can be stuck in the limiting port 58 to complete the fixation of the evaporator 51 and the condenser 52.

[0062] As Figure 2 and 9 shown, the ventilation component 6 includes an intake fan 61 and an exhaust fan 62. Among them, there are two intake fans 61, which are respectively installed in the intake fan mounting rings 42 on the mounting box cover plate 4 by screws, and the intake fan 61 corresponds to the position of the intake holes 41 on the mounting box cover plate 4.

[0063] The exhaust fan 62 is a turbo fan. There are four exhaust fans 62, which are fixed on two side surfaces of the mounting box 3 by screws, and the exhaust fan 62 corresponds to the position of the exhaust holes 33 on the mounting box 3.

[0064] The intake fan 61 sucks the hot and humid air in the integrated power supply housing 1 into the dehumidification and heat dissipation module 2, and then after being cooled and dehumidified by the dehumidification and heat dissipation component 5, the cold and dry air is discharged into the integrated power supply housing 1 through the exhaust fan 62 to complete dehumidification and cooling.

[0065] For the convenience of automatic control, a temperature and humidity sensor is also installed outside the dehumidification and heat dissipation module 2, and the automatic switch of the dehumidification and heat dissipation module 2 is controlled through the sensor.

[0066] The usage process of this embodiment: When the temperature and humidity sensor detects that the temperature or humidity in the integrated power supply housing 1 is relatively high, the dehumidification and heat dissipation module 2 is started. The intake fan 61 sucks the air in the integrated power supply housing 1 into the dehumidification and heat dissipation module 2. The hot and humid air contacts the heat dissipation fins 55 and the condensing pipes 54 for heat exchange, and then condenses and falls into the lower water storage tank 32. The cooled and dehumidified air is then discharged into the integrated power supply housing 1 through the exhaust fan 62. In this way, the temperature reduction and dehumidification of the integrated power supply housing 1 are realized, and it is convenient to use.

[0067] In addition, the modular dehumidification and heat dissipation module 2 not only simplifies the installation process, but also gives users extremely high flexibility, allowing the number of dehumidification and heat dissipation modules 2 to be increased or decreased according to actual needs to achieve the best temperature control and humidity control effects, and it is convenient to use.

[0068] The above embodiments are only used to illustrate the technical idea of the present utility model, and the protection scope of the present utility model cannot be limited thereby. Any modification made on the basis of the technical solution according to the technical idea proposed by the present utility model falls within the protection scope of the present utility model.
