Maintenance and Notice of High Power Radiator

In the room close to the radiator as far as possible to adhere to a certain heat dissipation space, do not accumulate debris on the radiator or in front of the radiator, otherwise it will affect the radiation effect of the radiator. High Power Heat Pipe Radiator

Valves in heating pipes should not be switched on and off at will. When the heating system first moves, it usually needs to be debugged. Detailed to each household is to adjust the valve of each riser to the appropriate position, turn over the manual exhaust valve of each radiator, discharge the air collected in the radiator, or turn over the exhaust valve of the collector installed on the top of the system. The debugging is completed until each radiator is heated up. Once the commissioning is completed, the valve should be fixed and cannot be switched on and off at will.

Heater sheet can not be arbitrarily changed orientation, the installation of heating sheet is arranged in the direction conducive to indoor heating, can ensure the relative average of air convection and indoor temperature, once the orientation is changed, the imbalance of indoor temperature will be formed. On the other hand, once the pipeline and heater sheet are moved, it will be very easy to leak, forming unnecessary loss at home.

If you can't discharge water from the system at will and there is no hot water in the pipeline, you need to add cold water to make the pipeline system adhere to the certain pressure. The more hot water is lost, the water temperature in the pipeline network will decrease rapidly, resulting in a decrease in indoor temperature. Brothers who use steel heating should pay attention to closing the valve in time when stopping heating. It is full of water in the heating. This can extend useful life. Conditional copper-aluminium composite heating sheet can also be maintained in full water.

There are still many ways to protect and maintain the radiator. If the radiator presents a big problem, we should try to invite professional HVAC engineers or technicians to protect it for us, so as to avoid more hidden dangers and affect the use of the radiator and its service life.

1. Appearance Quality Requirements of High Power Radiators

1.1 There should be no shrinkage, rust and crack on the surface of the radiator.

1.2 The metal fasteners (pressure plate, cover, disc spring) of flat radiator and the conductive sheets of water-cooled radiator should be maintained by coating.

1.3 The maximum allowable surface roughness Ra of the radiator countertop is 3.2, M.

1.4 The flatness of the radiator mesa is not less than 9 grades.

1.5 The radiator (including radiators, fasteners and insulators) used in wet tropical power semiconductor devices should be protected from dampness, salt spray and mildew. Its ability to withstand dampness, salt spray and mildew should conform to the corresponding specifications for tropical power semiconductor devices.

1.6 Fasteners and insulators for radiators shall be compatible with GBB446.3 (radiator insulators and fasteners for power semiconductor equipment)

1.7 The tightening moment or tightening pressure of radiators and power semiconductor devices shall conform to the relevant rules of the commodity specifications of equipment.

1.8 Medium pin size for flat radiator mesa: 2.5mm in diameter, lmmo for high surface

2. Requirements for the Application of Environmental Conditions

2.1 For the quality of cooling water, the resistivity of circulating water should not be less than 2.5Ki2, the PH value should be between 6} 9, the temperature of inlet water should not be higher than 35 C, and the flow rate of water should be 4-18L/min.

2.2 When used in high voltage or high voltage equipment, it is necessary to ensure the above water quality requirements or higher water quality requirements.

2.3 During the operation of water-cooled radiators, special attention should be paid to water leakage prevention, blocking prevention and condensation prevention.

2.4 When air-cooled radiator is installed, the radiator blade should follow the direction of cooling air flow; the inlet air temperature is not higher than 400C, and the inlet wind speed is 4-6mls; 2.5 Because the air-cooled radiator has the characteristics of wind resistance parameters, the selection of the radiator in the whole machine should be based on the load demand and the ability of the fan, check the relationship curve between the heat resistance, flow resistance and wind speed of the radiator, and summarize and think about the heat resistance and wind speed of the radiator. Wind resistance two parameters.

3. Damage and identification of residual radiators on the market presents many low-priced and low-quality residual radiators. This kind of radiator is far away from the national industry standards in terms of raw materials, processing requirements, component quality and other aspects. It has a great impact on the life of equipment and the quality of the whole machine in operation. Users can distinguish when they are available from the following aspects:

3.1 The quality of raw materials (purity, thickness, processing accuracy, etc.) and manufacturing technology (cracks and shrinkage holes occurring in casting), low quality raw materials and rough and defective technology will directly sound the thermal conductivity of radiator.

3.2 The surface roughness and flatness of the radiator touching table directly affect the touching thermal resistance and pressure drop.

3.3 Disk-shaped spring for radiator should ensure that after 24 hours of flattening, the tension spring should be stable from the height. Otherwise, the tension spring may fail after a period of time, which will lead to poor touch between radiator and tube core.

4. Questions on the Repeated Use of Radiator Replacement Components

 installing a radiator, it requires a lot of pressure or torque. Because the diameter of the radiator mesa is larger than the diameter of the tube core, under the action of pressure or moment, the mesa of the radiator will inevitably deform. If the same diameter or larger diameter of the tube core is mounted on the radiator, it will cause poor touch between the table and the outer surface of the tube core, thus failing to ensure outstanding heat dissipation.

If the user needs to reuse the radiator, it must ensure that the surface roughness, parallelism and flatness of the radiator countertop meet the demand, otherwise in operation, it is very simple to damage the equipment due to overheating. Especially for water-cooled series radiators, before repeated use, it is necessary to carefully check the deformation of their countertops. If there is a clear subsidence, they should be replaced.

In order to ensure excellent heat dissipation conditions, each tube core should have the corresponding radiator matching.

5. Avoidance of SS Series Radiator Condensation

In hot and humid season, the water-cooled radiator simply presents the appearance of condensation. If we do not pay attention to it, it will easily lead to equipment insulation reduction and short circuit fault. For most application environments, attention should be paid to the following things to avoid condensation.

5.1 In hot and humid season, pay attention to the difference between ambient temperature and cooling water temperature not less than 5 C.

5.2 When power failure occurs, the water shall be shut down immediately after closing the knife; when starting, the water shall be closed immediately after opening and closing operation is closely linked with the water cut-off operation, and the order can not be inverted.

6. Application in High Frequency Circumstances
