Uniform-section upright main water passage alloy belt water-cooled resistor

Abstract

The invention relates to a uniform-section upright main water passage alloy belt water-cooled resistor, which mainly comprises a corrugated alloy belt resistor core, a uniform-section upright main water passage main board, two uniform-section upright main water passage side boards and two metal electrodes, wherein the uniform-section upright main water passage main board and the two uniform-section upright main water passage side boards are made of PVDF (polyvinylidene fluoride) fluoroplastic. Both sides of the uniform-section upright main water passage main board are provided with symmetrical open water channels, which consist of upright main water channels and curved water channels connected with the upright main water channels, the water channels on both sides are connected to form a serial water passage or parallel water passages according to need, and the bottom is provided with a water inlet and a water outlet; one side of each uniform-section upright main water passage side board is provided with an open water channel which corresponds to the open water channel on the uniform-section upright main water passage main board; the two electrodes are enchased on the uniform-section upright main water passage main board, one end of each electrode is extended out of the open water channel to serve as an internal electrode, and the other end of each electrode is extended out of the side or top of the main board to serve as an external electrode; and the corrugated alloy belt is wound in the open water channels according to the trend of the water passage, both ends of the corrugated alloy belt are respectively soldered on the two internal electrodes, and thereby the corrugated alloy belt resistor core is formed.

Description

1. Technical field [0001] The invention belongs to the field of water cooling resistors. 2. Background technology [0002] In the existing water-cooled resistors, an alloy strip or wire is wound on the outer wall of a porcelain tube to make a resistance core, and the resistance core is put into a water cavity, and the water cavity is sealed by a sealing ring. When working, the water flowing in the water cavity will take away the heat generated by the resistance core, thereby greatly increasing the power density of the resistance core. [0003] Disadvantages of this type of resistor: [0004] 1. The structure is complex and there are many parts; [0005] 2. A sealing ring should be used for sealing. The life of the sealing ring is short, and it will be replaced after a few years. [0006] 3. The cross-sectional area of ​​the internal water chamber of the resistor is larger than that of the external waterway, the flow rate of the internal water chamber is slower than that o...

AI Technical Summary

Problems solved by technology

[0004] 1. The structure is complex and there are many parts;

[0005] 2. The sealing ring should be used for sealing. The life of the sealing ring is short and it needs to be replaced after a few years.

[0006] 3. The cross-sectional area of ​​the internal water chamber of the resistor is larger than that of the external waterway, the flow rate of the internal water chamber is slower than that of the external waterway, and the shape of the internal water chamber is complex, and the water flow rate is different everywhere, which results in a certain internal water chamber. The flow rate of the water at the place is much lower than the flow rate required by the design, then the impurities in the cooling water will be deposited there, breeding microorganisms, and affecting the water quality of the entire water system

[0007] There is little water in the water chamber inside the resistor, and when there is a water outage, the water will boil quickly, causing damage to the system
