Description

Technical Field

[0001] The utility model belongs to the field of intelligent switching power supplies, and in particular relates to an intelligent switching power supply with good heat dissipation effect. Background Art

[0002] A switching power supply is a type of power supply. With the development of electronic technology, intelligent switching power supplies are increasingly used in all aspects of life because of their more stable voltage / current, smaller ripple factor, smaller power, and faster response time. The switch components in the intelligent switching power supply are more sensitive to temperature, so better heat dissipation and ventilation conditions are required. The current intelligent switching power supply generally only uses the heat dissipation ports opened on the power box body to assist in heat dissipation, and the heat dissipation effect is poor. It is necessary to design an intelligent switching power supply that can enhance heat dissipation.

[0003] The existing Chinese utility model patent with announcement number CN218301955U discloses an intelligent switch power box, which relates to the technical field of fuel cell-related production equipment. The utility model includes a box body and a power source body inside the box body. Positioning plates are provided at the front and rear parts of the left and right sides of the power source body, and strip-shaped openings are provided at the front and rear parts of the bottom side of the box body; limiting plates are fixed at the left and right parts of the lower side of the box body between the two strip-shaped openings, and two U-shaped blocks are provided at the position between the two limiting plates; wherein, springs are fixed to one side wall of the U-shaped blocks corresponding to the limiting plates that are close to each other; T-shaped pull rods are provided at the left and right sides of the lower side of the box body; and a heat dissipation dustproof plate is provided inside the box body on the upper side of the power source body. The utility model limits the power source body to the internal position of the box body through the positioning plate, thereby ensuring the stability of the position of the power source body inside the box body. At the same time, the setting of the heat dissipation dustproof plate can accurately protect the power source body and realize the function of quickly replacing or cleaning the heat dissipation dustproof plate.

[0004] Therefore, in view of the fact that the above-mentioned traditional intelligent switching power supply relies on the box ventilation structure to assist in heat dissipation, which is poor and not conducive to the stable operation of the switch component, a new type of intelligent switching power supply is developed, which uses a built-in temperature sensor and an external air blowing heat dissipation mechanism driven by a motor to enhance the heat dissipation and ventilation of the equipment when the internal temperature is too high. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an intelligent switching power supply with good heat dissipation effect, which aims to solve the technical problem that the traditional intelligent switching power supply relies on the box ventilation structure to assist in heat dissipation, which is poor and is not conducive to the stable operation of the switch component.

[0007] (2) Technical solution

[0008] In order to solve the above technical problems, the utility model provides an intelligent switching power supply with good heat dissipation effect, which includes a power box and a back plate installed on the upper end of the power box.

Accelerated heat dissipation holes are opened on the rear side of the upper end of the back plate. Through openings are opened symmetrically at the front end of the power box. An L-shaped locking piece is arranged between the upper end of the power box and the upper end of the back plate. A blower is installed on the upper end of the locking piece, and the blower is arranged above the accelerated heat dissipation holes.

When the intelligent switch component is running and generating heat, the temperature sensor monitors the temperature changes inside the power box in real time. When the temperature rises to a certain threshold, a signal is sent to the control unit of the motor. The motor starts and controls the locking plate to rotate counterclockwise by ninety degrees through the transmission shaft, so that the blower is above the accelerated heat dissipation hole. The blower starts synchronously to blow air into the power box, squeezes the internal hot air out of the heat dissipation slot, and accelerates the cooling inside the power box.

[0010] Furthermore, a temperature sensor and a motor are installed on the inside of the power box. A through hole is opened on the rear side of the upper end of the power box.

The rotation direction is clockwise or counterclockwise, and each rotation is ninety degrees.

[0012] Furthermore, a No. 1 dustproof net with a diameter larger than the diameter of the accelerated heat dissipation hole is installed at the right end of the locking plate. The No. 1 dustproof net is arranged on the upper side of the power box. In a normal state, the No. 1 dustproof net is above the accelerated heat dissipation hole. The hot air in the power box slowly escapes outward through the accelerated heat dissipation hole, and the No. 1 dustproof net intercepts external dust and impurities.

[0013] Furthermore, a slider is provided on the inner side of the through-hole, a guide column is longitudinally installed on the inner side of the through-hole, the slider is movably connected to the outer side of the guide column, the slider moves stably longitudinally in the through-hole through the guide column, and the guide column is used to horizontally position the slider to prevent it from slipping out of the through-hole.

[0014] Furthermore, the front end of the slider is fixedly connected to a movable frame, the upper end of the movable frame is fixedly connected to a snap piece, the snap piece is arranged on the upper side of the power box and the back plate, the spring has elastic expansion performance, and produces a downward pushing effect on the slider, so that the snap piece is tightly squeezed on the back plate to form a locking effect.

[0015] Furthermore, a spring is fixedly installed between the upper end of the slider and the upper end of the inner wall of the through opening, and a No. 2 dustproof net is installed at the front end of the movable frame. Through the through opening and the No. 2 dustproof net, the hot air in the power box can also escape outward from the front end, and the No. 2 dustproof net intercepts external dust and impurities.
