The titanium plate heat exchanger is safe and reliable to use: two sealing devices are designed between the plates, and a signal hole is provided, once a leak occurs, it may be external, that is, to prevent the mixing of the two media to play a safety alarm.
Small cooling water: titanium plate heat exchanger due to the geometry of its flow path, and the two liquids are very high thermal efficiency, so the cooling water consumption can be greatly reduced. This in turn reduces the installation costs of pipes, valves and pumps.
Finned titanium tube heat exchangers are also known as tube fin heat exchangers. Its structural characteristics are equipped with many fins on the outer surface or inner surface of the heat exchanger tube. Common fins are longitudinal and transverse. Titanium fin row tube heat exchanger is used as a condensing unit, which is widely used in industry. Using gas instead of water-cooled heat dissipation can not only be applied from areas with little water, but also in areas with abundant water resources, the choice of air cooling has also achieved great economic benefits.

Wire and cable are composed of conductors, insulation layers and protective layers. Under certain working conditions, they can safely operate and transmit electric energy. However, when they are under overload, short circuit, local overheating and other fault conditions and external heat, they can cause damage to the insulation material. , make the insulation resistance drop lose insulation ability, even burn. Cable fire is a vicious accident in the power system. When a fire accident occurs, the fire is fierce, the combustion is rapid, and the smoke is harmful. In addition, due to the narrowness of the active area around the cable, it is difficult to save, and the repair time is long and the loss is serious. Its occurrence will bring huge losses to the national economy and the lives and property of the people. Therefore, we should attach great importance to the fire protection of power system cables.
In the cable manufacturing process, the electrical insulation performance of the cable body is reduced, the insulation is destroyed, and hidden fire hazards are buried. The main reasons are as follows: the insulation medium contains impurities, moisture and air bubbles; the thickness of the insulation layer is not uniform; the surface between the main insulation and the conductor and the shielding layer is rough, there are burrs, there is an air gap, resulting in uneven distribution of the electric field intensity in the insulation layer.
The distance between the cable and the heat pipe is too short or the cable is overloaded for a long time. The temperature is too high to cause the insulation material to deteriorate and the overheating causes short-circuit auto-ignition, resulting in a decrease in insulation performance and breakdown ignition. Due to the thermal expansion and contraction phenomenon of the cables on the cable trays, the cable and the cable edges are mechanically damaged by the cable edges, which damages the cable's protective layer and insulation layer, and reduces the electrical insulation performance.
With the rapid development and application of high technology in today's world, in modern buildings, especially in intelligent high-rise buildings, various electrical and electronic systems are becoming more and more complex, and the lines are densely distributed, which brings great opportunities for office automation and agile communication. Convenience, at the same time, also highlights the increase in the number of electrical fire accidents year after year, which has brought negative effects to high-rise managers, users and maintenance personnel, adding to many annoyances.
