Heat Pipe Heat sink


Heat pipe heat dissipation principle of heat pipe Heat sink : heat pipe technology uses the evaporation and condensation of the working fluid to transfer heat. The general heat pipe consists of three parts, namely the tube shell, the liquid absorbing core and the end cap. The inside of the heat pipe is pumped into a negative pressure state. In this state, a certain amount of liquid is filled, and the boiling point of this liquid is relatively low , volatile, the inner wall of the heat pipe has a liquid-absorbing wick, which is composed of capillary porous materials. The heat pipe is divided into two ends, one end is the evaporation end, and the other end is the condensation end. When one end of the heat pipe is heated, the liquid inside the heat pipe will evaporate rapidly, and the vapor will flow from one end to the other end under the pressure difference, and release energy. It is made to condense into a liquid again, and the formed liquid flows back to the evaporation end under the action of capillary force along the capillary porous material. This has been circulating back and forth, and the heat is transferred from one end of the heat pipe to the other end.

The heat sink is a device used to dissipate heat for components that are easy to heat. It is made of aluminum/copper materials with high thermal conductivity to make radiators of different shapes such as plate, sheet, and multiple pieces. 

The heat dissipation efficiency of the heat sink not only depends on the characteristics of the high thermal conductivity of the heat sink material, but also the heat capacity of the heat dissipation medium of the heat sink and the effective heat dissipation area of ​​the heat sink. The radiator materials are mostly made of copper and aluminum. Copper has good thermal conductivity, is more expensive, difficult to process, too heavy, has a small heat capacity, and is easy to oxidize. Aluminum is lighter and has worse thermal conductivity than copper. Generally speaking, for heat sinks made of the same material and technology, the thicker the heat sink material and the larger the surface area, the better the heat dissipation effect.

Our heat sink mainly includes: aluminum extrusion + CNC machining large heat sink, FSW large heat sink, riveted heat sink, insert heat sink, heat pipe heat dissipation system, shovel heat sink, forged heat sink, application It is used to solve the heat dissipation solution of industrial automation, power & transmission, medical equipment, new energy transportation, instrument and testing equipment and other industries.

 Heat pipe is a heat transfer element with extremely high thermal conductivity. It was invented in Los Alamos National Laboratory in the United States in 1964 and reached the peak of theoretical research in the late 1960s in the 1970s Began to be widely used in the industrial field. It transfers heat through the vapor and liquid phase changes of the working fluid in the fully enclosed vacuum tube. It has extremely high thermal conductivity, which is hundreds of times the thermal conductivity of pure copper. It is known as the "thermal superconductor". Heat pipe heat sink is a new product that uses heat pipe technology to make major improvements to many old radiators or heat exchange products and systems.
Since the advent of heat pipes, the heat dissipation system of power electronic devices has undergone new development. Regardless of the heat dissipation method, the final heat dissipation medium is air, and the other is the middle loop connection. Natural air convection cooling is the most direct and convenient way, and the application range of self-cooling is rapidly expanded by heat pipes. Because the heat pipe self-cooling heat dissipation system does not require fans, no noise, maintenance-free, safe and reliable, the heat pipe air-cooling or even self-cooling can replace the water-cooling system, saving water resources and related auxiliary equipment investment. In addition, the heat pipe heat dissipation can concentrate or even seal the heating elements, and move the heat dissipation part to the outside or far away, which can prevent dust, moisture, and explosion, and improve the safety and reliability of electrical equipment and the scope of application.

The type of heat pipe radiator can be divided into:
Profile + heat pipe, shovel tooth + heat pipe, insert + heat pipe, buckle tooth piece + heat pipe, aluminum & copper plate + heat pipe

regis is a heat pipe radiator manufacturer with advanced heat pipe technology, looking for heat pipe heat sink or advanced cooling solutions, please contact us, we provide custom heat pipe heat sink design and manufacture .
Many fluids can be used as phase transitions in heat pipes. In conventional applications, deionized water is chosen as the working fluid due to its high latent heat, surface tension, thermal conductivity, and boiling temperature. The negative vacuum pressure inside the heat pipe causes the water to boil and turn into steam at a lower temperature than normal. The inner wick can vary depending on the application and orientation of the cooling unit. The three most common methods are:
  1. Grooves - low cost, doesn't resist gravity well
  2. Silkscreen - the most common method
  3. Sintering - highest performance and cost
