Description

Technical Field

[0001] The utility model relates to the technical field of dew point detection, in particular to a dew point detection system for a water-cooled radiator. Background Art

[0002] High-power induction heating power supplies are generally water-cooled. When the cooling water temperature is too low, condensation will occur. Severe condensation will cause insulation degradation, resulting in leakage, short circuit and other accidents, seriously affecting the service life and safety of the power supply.

[0003] The inverter device in the induction heating power supply generally uses IGBT. When the IGBT is working, it will generate a certain amount of loss and turn into heat. The total loss of the IGBT is composed of conduction loss and switching loss. The switching loss is related to the operating frequency. The higher the frequency, the greater the loss. The heat generated by the IGBT during operation must be dissipated as soon as possible, otherwise the IGBT core temperature will be too high to cause thermal breakdown, causing permanent damage. The cooling method is generally divided into natural cooling, forced air cooling, water cooling, etc. For low-power induction heating power supplies, natural cooling or forced air cooling can be used, but high-power power supplies can generally only be cooled by water.

[0004] A water channel is made in the radiator of the IGBT so that cooling water with a certain pressure flows through the radiator. The cooling water forms a heat exchange with the radiator, takes away the temperature of the radiator, and achieves the purpose of cooling the IGBT. In order to save water resources, the cooling water channel is generally recycled. The temperature of the cooling water will rise after it flows out of the radiator. It must be cooled before flowing into the radiator, otherwise it will not have a heat dissipation effect. The cooling method of cooling water generally adopts cooling towers, refrigerators, natural cooling and other methods. Among them, natural cooling and cooling towers require a large space and the cooling effect is also average. The cooling machine adopts a principle similar to air conditioning refrigeration, which has the advantages of small size and good cooling effect, and is widely used.

[0005] The cooling system using a refrigerator often encounters the problem of condensation on the radiator in actual use. Condensation on the surface of an object is related to the ambient temperature, the surface temperature of the object and the ambient humidity. The higher the ambient humidity, the easier it is to condense, and the greater the temperature difference between the environment and the surface of the object, the easier it is to condense. It can be seen from the dew point temperature table (Table 1) that when the ambient temperature is 26 degrees, if the relative humidity is 90%, condensation will occur when the surface temperature of the object is ≤24.1 degrees; if the relative humidity is 60%, condensation will occur when the surface temperature of the object is ≤17.2 degrees. At the same ambient temperature, due to different relative humidity, the dew point temperature differs by nearly 7 degrees. In other words, the dew point temperature will change with changes in ambient humidity and ambient temperature.

[0006] When using a refrigerator, the refrigeration temperature is often set at a certain temperature, and generally will not be changed according to changes in ambient temperature and humidity. Some customers set one temperature in summer and another in winter at most, which often leads to electrical insulation failures caused by condensation in actual use. Therefore, a dew point detection system for water-cooled radiators is invented. Utility Model Content
