Winshare heat pipe customization

Winshare Thermal Alloy: Highly efficient heat conduction, flexible customization, solving local heat dissipation problems.

What is Heat Pipe?

Heat pipes are heat transfer elements with extremely high thermal conductivity and are known as "super thermal conductors". It uses the evaporation-condensation phase change cycle of the working fluid in a closed vacuum tube to transfer heat. When heat is applied to one end of the heat pipe (evaporative end), the working fluid inside will quickly evaporate and absorb heat; The steam flows to the other end (the condensing end) driven by a small differential pressure, where it condenses and releases heat, transferring the heat efficiently. The condensed liquid flows back to the evaporation end through the wick structure inside the heat pipe, completing a continuous cycle.

The effective thermal conductivity of heat pipes can reach hundreds or even thousands of times that of pure copper, far exceeding any known metal material. Due to their passive, efficient, noiseless and flexible structure, heat pipes have become an ideal solution to solve the problems of local hot spot heat dissipation and heat homogenization in electronic equipment, industrial equipment and other fields, especially suitable for customized applications with limited space and high requirements for heat dissipation efficiency and reliability.

The core benefits of Winshare heat pipes

Excellent ultra-high thermal conductivity

The effective thermal conductivity of heat pipes far exceeds that of any known metal material, and can quickly transfer heat from the heat source to the heat dissipation area with very little temperature difference, making it ideal for solving the problem of high heat flux density.

Highly flexible shape customization

The heat pipe can be bent, flattened, stamped, and even made into complex three-dimensional shapes according to the actual application space, perfectly adapting to various compact and special-shaped heat dissipation spaces to achieve customized integration.

Passive operation with high reliability

The heat pipe works without external power or moving parts, which means it is extremely reliable and long-lasting, and operates without noise, vibration, and low maintenance.even made into complex three-dimensional shapes according to the actual application space, perfectly adapting to various compact and special-shaped heat dissipation spaces to achieve customized integration.

Excellent temperature equalization ability

Heat pipes can quickly diffuse heat from local hot spots to the entire heat dissipation surface, achieving temperature uniformity, effectively reducing chip junction temperature, and improving equipment performance and life.

Wide range of temperature adaptability

By selecting different working fluids, heat pipes can operate efficiently over a wide temperature range from minus tens of degrees to more than two hundred degrees, meeting the needs of various demanding environments.

Cost-effective cooling solution

Compared to active cooling systems, heat pipes provide high-performance heat dissipation while having lower initial and operating costs, making them a cost-effective batch choice for many medium- to high-load applications.

Winshare Heat Pipe Technology Principles

The core working principle of heat pipes is based on phase change heat transfer, which allows them to absorb heat from the heat source end and quickly transfer it to the heat dissipation end with great efficiency. The entire process is circulated in a closed vacuum chamber

Evaporation

The transfer of heat from a heat source (e.g., CPU, LED chip) to the evaporation section of the heat pipe. The working fluid (such as water, methanol, etc.) inside the evaporation section absorbs heat and quickly changes from liquid to gaseous (steam).

Vapor Flow

Since the temperature at the evaporation end is slightly higher than at the condensing end, a small pressure difference is generated, and the steam flows to the condensation section at a very fast speed in the tube.

Condensation

After the steam reaches the condensation section, it transfers heat to the radiator or cooling medium, and its own condensation turns back into a liquid state. Liquid Return: The condensed liquid passes through the Wick Structure inside the heat pipe and uses capillary force (not gravity) to flow back to the evaporation section to complete a closed cycle.

This continuous evaporation-condensation-reflux cycle allows heat pipes to transfer large amounts of heat energy with very small temperature differences, and their effective thermal conductivity far exceeds that of any solid metal, which is a key technology for efficient thermal management.

Winshare Heat Pipes: Frequently Asked Questions (FAQs)

Q Is the heat dissipation performance of heat pipes affected by direction?

A Yes, the heat dissipation performance of heat pipes can be affected by the direction of gravity. The best performance is when the evaporation end is higher than the condensation end (gravity-assisted direction). The performance is secondary when placed horizontally; Capillary requirements are highest when the evaporation end is lower than the condensation end (in the anti-gravity direction), and sintered heat pipes are generally better suited for anti-gravity applications.
Q How long does the heat pipe last?

A Properly designed and manufactured heat pipes for a very long life. Winshare's heat pipes use high-purity materials and strict sealing processes to ensure that the internal working fluid is not lost. Under normal operating conditions, their lifespan often matches that of electronic devices, or even longer, up to decades.
Q What is the working fluid inside the heat pipe? Is it safe?

A The working fluid inside the heat pipe is selected according to the operating temperature range, the most commonly used is water, in addition to methanol, acetone, ammonia, etc. These fluids are sealed inside the heat pipes and do not leak into the outside environment. The working fluid and manufacturing processes we use comply with environmental and safety standards, ensuring that the products are harmless to humans and the environment.
Q What is the difference between heat pipes and vapor chambers?

A Heat pipes are linear heat transfer elements primarily used to transfer heat from one point to another. The vapor chamber can be understood as a two-dimensional planarized heat pipe, which can quickly diffuse and homogenize heat across the entire surface, suitable for surface uniformity of high heat flux density chips, and provide stronger local heat dissipation capabilities.
