Description

Technical Field

[0001] The utility model relates to a filter, in particular to a filter for preventing electromagnetic information leakage, belonging to the technical field of filters. Background Art

[0002] The primary function of an electromagnetic leakage filter is to effectively filter out electromagnetic leakage signals from the power input or signal transmission lines, thereby reducing the impact of electromagnetic interference on the device and protecting sensitive information within the device from leakage. Through internal filtering circuits, the electromagnetic leakage filter utilizes components such as capacitors, inductors, and resistors to filter electromagnetic leakage signals from the power input or signal transmission lines. These components absorb, reflect, or direct electromagnetic energy, reducing it to a safe level and preventing electromagnetic information leakage and electromagnetic interference.

[0003] In the prior art, a filter disclosed in announcement number CN220774701U includes a cavity, a resonator, and an elastic sleeve. The cavity has a mounting hole and a first limiting step. The first limiting step abuts the resonator to limit the resonator from being further inserted into the mounting hole along the depth direction of the mounting hole. One of the mounting hole wall and the resonator is used to engage with the elastic sleeve, and the other of the mounting hole wall and the resonator has a second limiting step, which abuts the elastic sleeve. The resonator is fixed to the cavity through the mounting hole, the first limiting step, the second limiting step, and the elastic sleeve, without requiring the cavity to be machined with a threaded hole. This solves the technical problems of low processing efficiency and high processing cost of the cavity of existing filters, thereby reducing the processing cost of the cavity.

[0004] In the above technical solution, the resonant component is fixed to the cavity through the mounting hole, the first limiting step, the second limiting step and the elastic sleeve, and the cavity does not need to be machined with a threaded hole, which reduces the processing cost of the cavity. However, it is not convenient to dissipate the heat of the filter during use, and the parts inside the filter will generate heat during operation, and it is unable to dissipate the internal heat. In view of this, a filter that prevents electromagnetic information leakage is provided to overcome the above defects. Utility Model Content

A heat-absorbing gasket 24 is installed on the lower surface of the heat-absorbing gasket 24. Several filter capacitors 3 are tightly fitted on the lower surface of the heat-absorbing gasket 24. A cooling mechanism for cooling the heat dissipation mechanism is provided on the upper surface of the water tank 2. The cooling mechanism includes a heat dissipation fin 4, which is fixed to the upper surface of the water tank 2.

A mounting plate 42 is installed on the upper surface of the fin 4, and two cooling fans 43 are installed inside the mounting plate 42. Coolant is stored in the water tank 2. The coolant in the water tank 2 can be extracted by the delivery pump 21 and sent to the inside of the heat conducting plate 23 through the delivery pipe 22. The heat absorbing gasket 24 can absorb the heat generated during the operation of the filter capacitor 3, thereby effectively reducing the internal heat and improving the service life of the filter. The heat pipe 41 arranged on the cooling fin 4 can absorb the heat in the coolant and then transfer it to the cooling fin 4.

When in use, the filter capacitor 3 inside the filter body 1 can absorb, reflect or guide electromagnetic energy, thereby reducing it to a safe level to prevent electromagnetic information leakage and electromagnetic interference.

[0024] Working principle: Before using the filter to prevent electromagnetic information leakage, first place the filter body 1 in a suitable position, then tighten the fixing bolts 6 on the fixing plate 5 to fix the filter body 1, and then use the fixing block 7 set on the filter body 1 to connect the wires of the external device and the terminal 8, and then tighten the fixing nut 9 to fix the guide to achieve the connection between the external device and the filter. When in use, the filter capacitor 3 inside the filter body 1 can absorb, reflect or guide electromagnetic energy, thereby reducing it to a safe level to prevent electromagnetic leakage. Information leakage and electromagnetic interference occur. Coolant is stored in the water tank 2. The coolant in the water tank 2 can be extracted by the delivery pump 21 and delivered to the inside of the heat conduction plate 23 through the delivery pipe 22.
