Benefits of technology
The patent is about a cooling material that is added to a fabric to help spread heat away from electronic devices. The material contains ceramic particles that have high thermal conductivity, which allows the heat to be quickly transferred to the outside. This results in a more efficient way to cool electronic devices while using the fabric.
Problems solved by technology
However, both the fins and the fans occupy an additional space to accommodate the fans or the fins, such that the fans or the fins are unsuitable for the portable electronic products that are designed toward size minimization.
The aluminum-magnesium alloy is applied as a case for the portable electronic product to solve the space problem, but the cost of the aluminum-magnesium alloy is high compared with the fans or the fins.
However, since the operational power of the portable electronic product tends to get high, the heat-dissipating effect provided by the intervals to dissipate the heat generated from the portable electronic product is insufficient.

Embodiment Construction
[0019]With reference to FIG. 1, FIG. 2 and FIG. 3, a preferred embodiment of a fabric material in accordance with the present invention comprises a fabric body 10, a cooling stuff 20, and an auxiliary cooling layer 30.
[0020]The fabric body 10 comprises multiple fibers 11 and multiple intervals. The fabric body 10 is woven by the fibers 11, such as carbon fibers, glass fibers, or aramid fibers. Each interval is formed between two adjacent fibers of the multiple fibers 11. The cooling stuff 20 is coated on the fabric body 10, fills the intervals, and comprises a stuff body 21 and multiple ceramic particles 22. The stuff body 21 is made of resin, wherein the resin is a viscous liquid initially, and then the resin undergoes aging to make the stuff body 21 hardened. The ceramic particles 22 are distributed within the stuff body 21. Preferably, each ceramic particle 22 is on a nanometer scale. The auxiliary cooling layer 30 is combined with the cooling stuff 20. The auxiliary cooling laye...

Abstract
A fabric of composite material has a fabric body and a cooling stuff. The fabric body is woven by multiple fibers. The cooling stuff is coated on the fabric body and combined with the fabric body, and has a stuff body and multiple ceramic particles. The stuff body infiltrates within the fabric body. The ceramic particles are distributed within the stuff body. The ceramic particles have high thermal conductivity and high coefficient of thermal radiation. Therefore, the fabric can provide sufficient cooling effect for a portable electronic product.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a fabric, and more particularly to a fabric of composite material and a method of preparing the fabric of composite material.[0003]2. Description of Related Art[0004]Currently, a portable electronic product is designed to be small in volume while functions of the portable electronic product are continuously expanded. When the electronic product is reduced in size with high performance, an efficient heat dissipation mechanism ensures that the electronic product operates smoothly. Therefore, having a sufficient heat dissipation capability is important for the portable electronic product.[0005]Generally, the heat dissipation methods applied on an electronic product comprises using fans, fins, or aluminum-magnesium alloy. The fans or the fins are assembled on the electronic product, and the thermal grease is smeared between the electronic product and the fans or the fins to reduce the contac...
