Heat pipe is a heat transfer excellent artificial components, commonly used heat pipe consists of three parts: the main body of a closed metal tube, a small amount of internal working medium and capillary structure, the tube air and other debris must be excluded. Below I will introduce you to the knowledge about the heat pipe radiator.
What is a heat pipe radiator
The use of heat pipe technology can be many old radiators or heat exchanger products and systems to make significant improvements and produce new products. The thermal resistance of a radiator is determined by the thermal conductivity of the material and the effective area within the volume. Solid aluminum or copper heat sink in the volume of 0.006m3, and then increase its volume and area can not significantly reduce the thermal resistance. For double-sided heat dissipation of discrete semiconductor devices,
air-cooled all-copper or all-aluminum heat sinks can only reach the thermal resistance of 0.04 ℃ / W. While the heat pipe heat sink can reach 0.01 ℃ / W. In the natural convection cooling conditions, heat pipe heat sinks than the entity's performance can be increased by more than ten times.
Advantages of heat pipe radiator and aluminum (copper) solid radiator and water-cooled radiator
1, strong heat dissipation ability. Aluminum (copper) solid radiator in 6m / s wind speed,
thermal resistance of 0103e / W; while the heat pipe, water-cooled thermal resistance in the same conditions is only 0101e / W.2, cost-effective. In the same thermal resistance conditions of heat pipe radiator consumes only half of the material for the aluminum (copper) entity radiator, while the water cooling is not only more equipment, but also to increase the water system. Loop type heat pipe radiator Gezhouba Power Plant is currently a **** 3F, 14F, 19F high-power rectifier cabinet using the loop type heat pipe radiator, the principle of the loop type heat pipe is as follows: the loop heat pipe by the evaporator, steam section, condensing section, reflux section and the compensation chamber of the five parts, there is a set of capillary structure within the evaporator, the inner wall of the evaporator or the capillary structure of the vapor has a number of grooves. In the actual use of the process, the assembly circuit type heat pipe radiator power cabinet power device temperature rise is low, are running far below its limit junction temperature 0 state, to meet the demand for heat dissipation, but because of the circuit type heat pipe assembly form, so that the entire power cabinet are filled with radiator parts,
cabinet ambient temperature is high.3, heat pipe radiator has both the advantages of aluminum radiator and copper radiator, in the case of natural air-cooled, the thermal resistance of the smallest can reach 0104e / W, to achieve the natural conditions of efficient heat dissipation, while in use also has a fan with a thermostat, the ambient temperature over the limit of the fan is automatically activated after the limit, which ensures that the power device in the far lower than the limit of its / junction temperature of the state of the long-term operation of the rated. Moreover, the normal operation of the heat pipe radiator no noise, equipment dust less, which all give maintenance personnel overhaul brought great convenience.
