Description

Technical Field

[0001] The utility model relates to the field of electric control boxes, in particular to an air-cooled electric control box. Background Art

[0002] The electric control box is an important electrical equipment for opening, closing, controlling and protecting in the power system. The electric control box is mainly composed of measuring equipment, circuit breakers, disconnectors, load switches, operating mechanisms and various protective devices. If the heat in the electric control box is too large, it will seriously affect the reliability and service life of the electric control box body. Therefore, the heat dissipation of the electric control box is particularly important.

[0003] The existing electric control box is generally provided with a plurality of cooling pipes or water pipes on the side wall inside the box, and a water pump or other structure for transmitting and providing power is provided outside the box. The water pump or other structure supplies water to the cooling pipes or water pipes to remove the heat generated by various electronic components in the box, and the heat in the electric control box is removed through continuous repeated circulation, or a certain number of heat dissipation holes are directly added to the outside of the electric control box to directly dissipate heat through the heat dissipation holes, or a heat dissipation fan is installed inside the electric control box to increase the air circulation in the box through the operation of the heat dissipation fan, thereby removing the heat in the electric control box. However, these methods still have the following defects:

[0004] 1) The cooling efficiency of water cooling and direct heat dissipation through heat dissipation holes is limited. When the air temperature is too high in summer, the cooling efficiency of this method is very limited and the cost is high. Due to the high temperature in summer, the water temperature inside the cooling pipe is usually high. The internal water has poor heat absorption capacity and can only take away a limited amount of heat. The water itself absorbs heat slowly. In addition, the summer temperature is high and the heat dissipation speed is slow. Therefore, it is difficult to discharge the heat inside the electric control box. The heat dissipation through heat dissipation holes has a low heat dissipation efficiency. The number of heat dissipation holes is limited, and the heat dissipation holes are usually very small in diameter. Heat accumulates and is difficult to discharge in a short time.

[0005] 2) When the air temperature is too high in summer, the cooling fan is used to dissipate heat without fully considering the cooling needs during long-term high-load operation, which causes the cooling fan to increase in temperature during continuous use, thereby affecting the heat dissipation of the electric control box. When used for a long time, the internal cooling fan will generate a large amount of heat. If it cannot be effectively dissipated, the cooling fan itself will burn out. The cooling fan itself contains some electronic components. Although it can dissipate the heat inside the electric control box, the heat generated by itself cannot be dissipated. Long-term heat accumulation will cause damage to the cooling fan. Utility Model Content

[0006] In order to overcome the deficiencies of the existing technical solutions, the utility model provides an air-cooled electric control box, which can effectively solve the technical problems that the heat inside the electric control box is difficult to discharge and the cooling fan cannot effectively dissipate heat, which easily leads to self-burning.

[0011] Furthermore, a movable door is provided on the surface of the chassis via a hinge, and a door lock is provided between the door and the chassis.

[0012] Furthermore, the surface of the door is inlaid with tempered glass.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1) The utility model provides an air-cooled electric control box, which enhances air circulation through air inlet holes, and can blow air into the inside of the box through the cooling fan, so that the inside of the box is cooled down. The air blown by the cooling fan takes away the heat generated inside the box, and the hot air can be dispersed and discharged from the bottom frame through the cooling holes on the top of the top plate and the circulation holes on the side, so that the inside of the box can quickly dissipate heat, greatly improve the heat dissipation efficiency, and have a better heat dissipation effect, which solves the problem that a large amount of heat is accumulated by other electronic components inside the electric control box when it is used for a long time, making it difficult to discharge the heat inside the electric control box, resulting in the electric control box being easily burned;

[0015] 2) The utility model provides an air-cooled electric control box. A plurality of grooves, through holes and air outlet pipes on the surface of a fan mounting seat can allow air to enter or flow out, thereby accelerating the dissipation of heat inside the cooling fan, enabling the cooling fan to be in a good working condition, and achieving rapid heat dissipation of the cooling fan, thus solving the problem that the cooling fan inside the electric control box will generate a large amount of heat when used for a long time, and the cooling fan itself will be burned if it cannot be effectively dissipated.
