Description

Technical Field

[0001] The utility model relates to the technical field of JP cabinets, in particular to a JP cabinet with a heat dissipation structure. Background Art

[0002] JP integrated distribution box (JP cabinet for short) is a new integrated control box that integrates power distribution, metering, protection, control, and reactive power compensation. It is widely used in the power industry. Most JP integrated distribution boxes are installed in outdoor environments. The electrical components inside the JP integrated distribution box will generate a lot of heat when working. If this heat is not discharged in time, it will affect the normal operation of the internal electrical components, and in serious cases, it will cause damage to the components. In view of this, the JP cabinet needs to undergo a temperature rise test before leaving the factory to verify whether the JP cabinet meets the use standards. During the inspection, it is required that the cabinet door of the JP cabinet is completely closed when there is no power inside, and the exhaust fan inside the JP is tested when it is not powered on. The temperature rise is required not to exceed 70K.

[0003] The existing JP cabinet heat dissipation method completely relies on the ventilation shutters on the JP cabinet shell to dissipate heat. The opening gap of the shutter is originally very small, and the protection level is required to be no less than IP4X. Therefore, a protective net with an aperture of <=1mm is attached to the inner surface of the shutter opening, which greatly reduces the ventilation area and is not conducive to heat dissipation. Even if many more shutters are opened on the top cover and left and right side panels of the entire shell, the hot air in the cabinet and the normal temperature air outside the cabinet cannot form convection, and the effect is not very ideal when detecting the temperature rise experiment, making it difficult to pass the test.

[0004] In view of this, a JP cabinet structure is proposed to achieve good heat dissipation function. Utility Model Content

[0005] The utility model aims to provide a JP cabinet with a heat dissipation structure, which solves the problem that the existing JP cabinet only relies on ventilation shutters to dissipate heat, but has poor heat dissipation effect.

[0006] To achieve the above-mentioned purpose, the utility model provides a JP cabinet with a heat dissipation structure, including a cabinet body and a heat dissipation component;

[0007] The heat dissipation assembly includes a non-powered hood and a protective component. There are multiple non-powered hoods, and the multiple non-powered hoods are respectively connected to the cabinet and are respectively located at the top of the cabinet. The cabinet has multiple entry channels, and the multiple entry channels are respectively located below the cabinet. The protective component is provided at each entry channel.

[0008] Wherein, the protective component includes a protective net and a protective cover, the protective net is detachably connected to the cabinet and is located at the entrance passage; the protective cover is connected to the protective net.

[0009] Wherein, the protective cover includes a mounting piece and a cover body. The mounting piece is detachably connected to the protective net and is located on the side of the protective net away from the cabinet body. The cover body is fixedly connected to the mounting piece and is located below the mounting piece. The cover body has an opening, and the opening is located at the bottom of the cover body.

[0010] Wherein, the JP cabinet with a heat dissipation structure further includes a handle. The handle is detachably connected to the cabinet body and is located on the outer wall of the cabinet body.

[0011] Wherein, the JP cabinet with a heat dissipation structure includes a cable cover. The cabinet body has a cable channel, and the cable channel is located below the cabinet body. The cable cover is fixedly connected to the cabinet body and is located at the cable channel.

[0012] For a JP cabinet with a heat dissipation structure of the present utility model, a large amount of heat is generated when the electrical components inside the cabinet body are powered on. The temperature difference value between the inside and outside of the cabinet is about 60 degrees. Due to the large temperature difference between the inside and outside, that is, there is a large pressure difference between the inside and outside. When the hot air flow passes through the blades of the unpowered wind cap, there is a pressure difference on the inner and outer surfaces of the blades. The pressure difference pushes the blades to rotate. When rotating, a centrifugal force is generated to suck up the hot air inside and discharge it. The normal temperature gas outside the cabinet body enters through the inlet channel at the bottom or side of the cabinet body to supplement, and this cycle repeats continuously to discharge the heat inside the cabinet, achieving the effect of heat dissipation and temperature reduction. When doing the temperature rise experiment, the small fan inside the cabinet was originally not powered on, that is, the test was carried out under the condition that the fan was not powered on. Therefore, when doing the temperature rise detection, this heat dissipation structure is very ideal and practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0019] The first embodiment of this application is as follows:

[0020] Please refer to Figure 1 , wherein, Figure 1 is the overall structural schematic diagram of the JP cabinet with a heat dissipation structure according to the first embodiment of the present utility model. The present utility model provides a JP cabinet with a heat dissipation structure: including a cabinet body 101, a heat dissipation component, a handle 104 and a cable cover 105. The heat dissipation component includes a power-free wind cap 102 and a protective member. The cabinet body 101 has a plurality of access passages 103. Through the foregoing solution, the foregoing problems are solved. It can be understood that the foregoing solution can be used in xxx scenarios and can also be used to solve xxx problems.

[0021] For this specific implementation mode, the number of the power-free wind caps 102 is multiple. The multiple power-free wind caps 102 are respectively communicated with the cabinet body 101 and are respectively located at the top of the cabinet body 101. The multiple access passages 103 are respectively located below the cabinet body 101, and the protective member is arranged at each access passage 103.

[0022] The power-free wind cap 102 is a device that uses the principle of natural wind force and indoor and outdoor air convection to improve the indoor ventilation and air change effect. Its working principle is based on the natural wind speed in nature to drive the turbine inside the wind cap to rotate, thereby accelerating and changing the air flow direction, changing from parallel flow to vertical flow from bottom to top, so as to achieve the effects of ventilation and cooling, removing moisture and odor. The number of the power-free wind caps 102 is at least two, and they are installed on the top of the cabinet body 101. A plurality of the access passages 103 are arranged on the lower side surface of the cabinet body 101 for cold air to enter. The protective member is arranged on the access passage 103 on the side for protection and filtration. Small hole-shaped access passages 103 can also be arranged at the bottom of the cabinet body 101 for cold air to enter.

[0023] Among them, the handle 104 is detachably connected to the cabinet body 101 and is located on the outer wall of the cabinet body 101. The handle 104 is arranged on the outer wall of the cabinet body 101, which is convenient for people to exert force to carry the cabinet body 101, and is convenient to use.

[0024] Secondly, the cabinet body 101 has a cable channel 106, and the cable channel 106 is located below the cabinet body 101; the cable cover 105 is fixedly connected to the cabinet body 101 and is located at the cable channel 106. The cable channel 106 is arranged on the cabinet body 101 to facilitate the cable to enter the cabinet body 101, and the cable cover 105 is arranged at the cable channel 106 to protect the cable.

[0025] When using a JP cabinet with a heat dissipation structure according to this embodiment, a large amount of heat is generated when the electrical components inside the cabinet body 101 are energized. The temperature difference value between the inside and outside of the cabinet body 101 is about 60 degrees. Due to the large temperature difference between the inside and outside, that is, there is a large pressure difference between the inside and outside. When the hot air flow passes through the blades of the non-powered wind cap 102, there is a pressure difference on the inner and outer surfaces of the blades. The pressure difference pushes the blades to rotate, and when rotating, a centrifugal force is generated to suck up and discharge the hot air inside. The normal temperature gas outside the cabinet body 101 enters through the inlet channel 103 at the bottom or side of the cabinet body 101 to replenish, and this cycle continues, constantly discharging the heat in the cabinet to achieve the effect of heat dissipation and temperature reduction. When doing the temperature rise experiment, the small fan inside the cabinet body 101 was originally not energized, that is, the test was carried out under the condition that the fan was not energized. Therefore, when doing the temperature rise detection, this heat dissipation structure is very ideal and practical.

[0026] The second embodiment of this application is as follows:

[0027] On the basis of the first embodiment, please refer to Figure 2 and Figure 3 , among which, Figure 2 is the overall structure schematic diagram of the JP cabinet with a heat dissipation structure according to the second embodiment of the present invention. Figure 3 is the cross-sectional schematic diagram of the protection component according to the second embodiment of the present invention. The protection component of this embodiment includes a protection net 201 and a protection cover. The protection cover includes a mounting piece 202 and a cover body 203.

[0028] For this specific embodiment, the protection net 201 is detachably connected to the cabinet body 101 and is located at the inlet channel 103; the protection cover is connected to the protection net 201. The protection net 201 is installed at the inlet channel 103 to play a role in protection and filtration, effectively blocking tiny particles, dust, insects or other sundries from entering the inside of the cabinet body 101, thereby protecting the equipment inside the cabinet from damage or pollution, and the protection cover covers the protection net 201.

[0029] Among them, the mounting piece 202 is detachably connected to the protective net 201 and is located on the side of the protective net 201 away from the cabinet body 101; the cover body 203 is fixedly connected to the mounting piece 202 and is located below the mounting piece 202; the cover body 203 has an opening 204, and the opening 204 is located at the bottom of the cover body 203. The mounting piece 202 and the cover body 203 are integrally formed for mounting the cover body 203. The opening 204 of the cover body 203 is arranged at the bottom, and cold air enters from below, reducing the accumulation of dust inside the cover body 203 and further reducing the frequency and difficulty of cleaning.

[0030] When using a JP cabinet with a heat dissipation structure according to this embodiment, external cold air enters from the opening 204 of the cover body 203, and then enters the cabinet body 101 after being filtered by the protective cover, effectively blocking tiny particles, dust, insects or other sundries from entering the interior of the cabinet body 101, thereby protecting the equipment in the cabinet from damage or pollution.

[0031] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand the entire or partial processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
