1）. Heatpipe and heatpipe exchanger working principle:
Heatpipe basic working principle:heatpipe is composed of pipe cover,external expanded heating surface and end plug. Pulls out 1.3× (10 ˉ 1~10 ˉˉ 4) Pa negative pressure, and inject amount operating fluid sufficiently, then seals.The transmit heat is using working substance phase transition under vacuum condition. The substance will be carburated by evaporation when heating the heat pipe‘s evaporation section. It will coagulate into liquid that the vapor under the pressing of micro pressure and flow to the condenser section. Then it returns to the evaporator section under the gravity function. Moving in this endless cycles, the heat transfer from one to another point, it will achieve the heat dissipation.
2)、Basic features of heat pipe and heatpipe exchanger
• Inner heat pipe has small heat resistance, and have high heat dissipation ability.
• Pressure difference of heat pipe inner cavity is low, and have good equal isothermality
• Heat exchanger have good safety and it is suitable for heat exchange place which is combustible, explosive, corrosive etc.
• Heat exchanger is compact, it is economic and utility,
• and appeal to lower taste of heat recycle
• Abrasion resistance is good for high dust loading liquid.
• The temperature of heat pipe surface is higher than air pre-heater 20℃-30℃, so as to reduce corrosion greatly, and it has outstanding defended against the ash.
• Solve problem of the boiler air leakage, and improve the thermal efficiency
• 3)、Heatpipe and heatpipe exchanger application scope:
• Chemical industry and petroleum chemical industry
• Architecture and light textile industry
• Metallurgy industry
• Dynamical project
• Electronic and appliance project
• Solar energy
• Nuclear power project
• Spaceflight technology
