What is the difference between a water-cooled stack and an air-cooled stack?
The existing high-power metal stack needs to be formed by stacking a large number of electrode plates, but because the single-piece electrode plate is relatively thin, the electrode plate is easily deformed, causing damage to the metal stack. So, what is the difference between a water-cooled stack and an air-cooled stack?
What is the difference between a water-cooled stack and an air-cooled stack?
1. Air cooling conducts heat to the heat sink through solid metal (copper or aluminum) or heat pipe;
2. Water cooling conducts heat to the radiator through liquid (water or other liquid with good thermal conductivity). The fan blows the heat sink to dissipate heat as soon as possible.
3. In fact, air cooling and water cooling are all fans blowing fins to dissipate heat. The difference between the two lies in the conductive medium of the intermediate link. Dangers of water-cooled radiators: water-cooled radiators have certain risks due to the use of liquid medium for heat conduction. Once the pipes and joints are damaged, the liquid will leak, and the electrical components will be short-circuited and burned.
What are the technical elements of a water-cooled stack?
A water-cooled high-power metal stack includes a plurality of electrode plates; a frame is arranged between two adjacent electrode plates, and the frame is welded with the electrode plates. The utility model increases the thickness of the electrode plate by welding the frame between the two electrode plates, and also increases the thickness of the entire metal stack, improves the stability of the metal stack, and improves the electrical conductivity of the stack; The service life of the stacks; the welding method guarantees a stable connection between them. The frame is provided with a welding part, and the electrode plate is provided with a welding part that matches the welding part; On the same horizontal line, and, eh, the welding part and the welding part can also ensure that the distance between the welding points after welding is completed within a predetermined interval, so as to avoid unstable welding due to excessive distance. The convex part arranged on the frame, the welding part is the concave part set on the electrode plate; when welding, the convex part is placed in the concave part, so that the inner wall of the concave part and the side wall of the convex part are mutually defined, thus ensuring the joint part and the welding part The accurate positioning between the two electrodes reduces the probability of the welding protrusions protruding outward due to welding, and ensures that the distance between two adjacent electrode plates is within the specified value. One end of the electrode is provided with a water inlet, and the other end is provided with a water outlet which can be communicated with the water inlet; the water inlet and the water outlet can promote the circulating flow of cooling water between two adjacent electrode plates and improve the cooling effect. The inner wall of the water inlet is provided with a plurality of protrusions; the protrusions can slow down the water flow speed, prolong the heat absorption time of the water flow, and improve the utilization rate of water; the inner wall of the water outlet is provided with a plurality of protrusions. The welding part has a trapezoidal structure; the trapezoidal shape can reduce the difficulty of welding, and it is convenient to weld the edge of the welding part during welding.
