Description

Technical Field

[0001] This invention relates to the field of high-frequency switching power supply technology, and in particular to a high-low zone fireproof isolation cavity. Background Technology

[0002] In the field of modern power electronic equipment, high-frequency power switches are widely used due to their high efficiency and miniaturization. However, with the continuous increase in equipment power density, fire safety issues between high and low voltage zones are becoming increasingly prominent. During operation, high-frequency power switches are prone to generating localized high temperatures due to factors such as high current change rate and large switching losses. If fire isolation measures between high and low voltage zones are inadequate, flames or high-temperature gases may spread, causing equipment failure or even safety accidents.

[0003] Currently, when traditional high-frequency power switches are in use, the high rate of current change can easily generate localized high temperatures. If the fireproof isolation measures between the high and low zones are not in place, flames or high-temperature gases may spread, causing damage to the high-frequency power switch. Summary of the Invention

[0004] (a) Technical problems to be solved The purpose of this invention is to provide a fireproof isolation chamber for high and low zones, which solves the problem mentioned in the background art that inadequate fireproof isolation measures between high and low zones may lead to the spread of flames or high-temperature gases, thereby causing damage to high-frequency power switches.

[0006] As a further aspect of the present invention, a flow groove is provided inside the outer casing, and a top cover is bolted to the top surface of the outer casing. The top cover allows for the inspection and maintenance of the internal parts of the device.

[0007] As a further embodiment of the present invention, two sets of fixing plates are fixedly connected to the top surface of the top cover, and each set of fixing plates is provided with a handle. The handles enable the user to move the device.

[0008] As a further embodiment of the present invention, a control board is fixedly connected to one side of the housing, and a switch button is provided on the surface of the housing. The control board serves to control the operation of the device.

[0009] As a further embodiment of the present invention, a flow pipe is fixedly connected to the top surface of the water storage tank, and a sealing cap is threadedly connected to the outside of the flow pipe. The flow pipe serves to add cold water into the water storage tank.

[0010] As a further embodiment of the present invention, a mounting frame is fixedly connected to the top surface of the outer shell, and a sealing gasket is fixedly connected to the top surface of the mounting frame. The sealing gasket serves to prevent dust or moisture from entering the interior of the device.

[0011] As a further embodiment of the present invention, a protective cover is fixedly connected to one side of the water storage tank, and a cooling fan is provided on the surface of the protective cover. The cooling fan is used to cool the hot surface of the semiconductor cooling chip.

[0012] (III) Beneficial Effects This invention provides a high-low zone fireproof isolation cavity, which has the following beneficial effects: 1. The high and low zone fireproof isolation chamber, through the setting of fireproof components, ensures that the ceramic substrate on the outside of the high-frequency switching power supply has good high temperature resistance and non-combustible properties during use. Combined with the flame-retardant coating, it can prevent the internal electronic components from burning. The heat insulation layer has good heat preservation capabilities, thereby reducing the risk of fire in the high-frequency switching power supply, reducing circuit damage, ensuring safe operation, and extending the service life of the equipment.

[0013] 2. The high and low zone fireproof isolation chamber, through the setting of heat dissipation components, allows the semiconductor cooling chip to cool the water inside the water tank during use. When the water pump is started, the water pump delivers the water inside the water tank to the interior of the flow channel through the water inlet pipe. The cold water flows inside the flow channel to dissipate heat from the device, which can effectively reduce the operating temperature, ensure that the equipment operates within a safe temperature range, reduce equipment failures caused by high temperature, and improve the reliability and stability of the equipment.
