A brief introduction to heat pipes, the thermal conductivity of heat pipes

Thermal grease is a type of high thermal conductivity that has a high thermal conductivity. It is a common material used in heat dissipation systems to effectively transfer heat from the heat source to the heat sink, thus ensuring the stable operation of the equipment. The thermal conductivity of thermal grease refers to the amount of heat transferred through a unit area per unit of time at a certain temperature.

This is an important parameter to measure the thermal conductivity of thermal grease. The higher the thermal conductivity, the better the thermal conductivity of the thermal grease and the more effective it is in transferring heat to the heat sink. It is calculated as follows:

k = q (a * t) where k is the thermal conductivity, q is the heat transferred, a is the surface area of the radiator, and t is the time. Thermal grease is widely used in various fields, such as electronics, machinery, medical, etc. In the field of electronics, thermal grease is used in computers, servers, 、...

Heat pipes. Material: Copper + Coolant.

Specification: D2 D3 D4 D5 D6 D8 D10 Length: 50-500mm

This conversion process does not only transfer heat through the metal, but also uses the refrigerant in the copper tube as a heat exchange medium, and the thermal conductivity is about 200 times that of copper. No rust, no limescale, and the temperature range is 50 to 200

Summary. The thermal conductivity of a heat duct refers to the ability of heat to be conducted through a unit area per unit of time. For heat pipes, the higher the thermal conductivity, the better the heat transfer will be.

Regarding the thermal conductivity of heat pipes, I can tell you for sure that the thermal conductivity of heat pipes is generally between 10w (m·k) and 1000w (m·k). However, the specific value should be determined according to the heat pipes of different materials and structures.

The thermal conductivity of a heat duct refers to the ability of heat to be conducted through a unit area per unit of time. For heat pipes, the higher the thermal conductivity, the better its heat transfer effect. Regarding the thermal conductivity of heat pipes, I can tell you with certainty that the thermal conductivity of the hollow heat pipe lumen is generally between 10 w (m·k) and 1000 w (m·k).

However, the specific value should be determined according to the heat pipes of different materials and structures.

Thermal conductivity is an important performance indicator of a large material, and is often used to measure the heat transfer performance of a material. Materials with high thermal conductivity can conduct heat more quickly, so they are widely used in applications that require efficient heat transfer, such as heat pipes. A heat pipe is a device capable of conducting heat from one place to another.

It consists of two or more materials with different thermal conductivity properties, usually including an internal heat pipe and an external insulation. The internal heat pipes are usually made of materials with high thermal conductivity such as copper or aluminum, while the outer insulation is used to prevent heat loss. In addition to the thermal conductivity, the heat transfer performance of a heat pipe is also affected by other factors, such as the length, diameter, heat dissipation area, and operating temperature of the heat pipe.

In practical applications, we need to select the right heat pipes according to the specific needs to achieve the best heat transfer effect.

Summary. Hello, glad to answer for you. For the question of the direction of heat pipe heat conduction, mine is:

The heat pipe conduction direction is mainly along the direction of the pipe shaft. The working principle of the heat pipe is to use the working medium to absorb heat and evaporate in the tube, and then condense the working medium through the condenser transmitted from the cold side, so that it can release the absorbed heat. This process is achieved by the endothermic vapor in the tube is conducted in the direction of the tube shaft to the cold face condenser and the heat is released at the cold face condenser.

Therefore, the direction of heat conduction of heat pipes is mainly carried out in the direction of the tube axis.

Hello, glad to answer for you. Daqiaoqin's question about the heat pipe heat conduction direction, my is: the heat pipe heat conduction direction is mainly along the pipe shaft direction.

The working principle of the heat pipe is to use the working medium to absorb heat and evaporate in the tube, and then condense the working medium through the condenser transmitted from the cold side, so that it can release the heat collected after sucking and rolling. This process is achieved by the endothermic vapor in the tube is conducted in the direction of the tube shaft to the cold face condenser and the heat is released at the cold face condenser. Therefore, the direction of heat conduction of heat pipes is mainly carried out in the direction of the tube axis.

Fellow, I really didn't understand, I can be more specific.

Heat pipe heat conduction is the process of transferring heat from one place to another using the heat transfer principle of heat pipes. A heat pipe is a device consisting of two relatively independent confined areas, in which a special working medium is disturbed. When one side of the heat pipe is heated, this working medium is heated and evaporates into a gas.

The gas moves from the gas area of the Talker dust heat pipe to the cooling area of the heat pipe, where it cools and condenses into a liquid. This cyclic process of this working medium is repeated over and over again, thus transporting heat from one side to the other. Heat pipe heat transfer is typically used for efficient thermal management applications, such as heat dissipation and temperature control in electronic devices.

I hope my reply is helpful to you and I wish you a happy life.

The heat pipe is a cooling rod suitable for narrow locations such as slender cores and areas that ordinary cooling water cannot reach, it has good heat transfer performance, the heat from one Mori Sakura end can be quickly transferred to the other end, and the cooling water is connected at the right position to achieve a worst heat conversion process.

Uses: Used for plastic mold maintenance, mold improvement, high-speed heat absorption and cooling, to prevent product shrinkage and deformation, etc.

Method and use: When the heat conduction pipe is inserted into the mold, apply thermal paste on the surface, and try to make the thermal paste fill the gap between the mold hole and the heat pipe.

The heat pipe is suitable for use in narrow locations such as slender cores and areas that cannot be reached by ordinary cooling water, it has good heat transfer performance, heat from one end can be quickly transferred to the other end, and the cooling water or heat sink is connected at the right position to achieve an optimal heat conversion process.

The heat exchanger tube is one of the elements of the heat exchanger, which is placed in the cylinder and used for the exchange of heat between the two media. In addition to light heat exchanger tubes, heat exchangers can also use a variety of reinforced heat transfer tubes such as fin tubes, threaded tubes, spiral groove tubes, etc. When the heat coefficient difference between the two sides of the inner diameter of the tube is large, the fins of the finned tube should be arranged on the side with the low heat supply coefficient.

When there is a temperature difference between the two ends of the heat pipe, the liquid at the evaporation end will quickly vaporize, bringing heat to the condensing end at a very fast speed.
