The high heat conduction substrate is located the colloidal silica and is kept away from a ventilation groove terminal surface, absorbs the heat of radiation source and goes out through high heat conduction substrate, makes the colloidal silica lateral wall can pass through the flowing air through vertically and horizontally staggered's ventilation groove, and then takes away the heat of colloidal silica inside. The curved ventilation slot increases the contact area with air, so that the internal heat can be fully released.

Description

Heat dissipation and wave absorption silica gel sheet

Technical Field

The utility model relates to a silica gel piece technical field especially relates to a heat dissipation is inhaled ripples silica gel piece.

Background

Silica gel (also called silicon rubber) is a safe and nontoxic polymer environment-friendly material and has stable chemical properties. Silica gel has the characteristic of difficult substitution of other similar materials, so that the silica gel is widely applied to industries such as electronic appliances, medicines, automobiles, machinery, buildings, textiles, chemical industry, light industry, printing and the like.

With the development of modern science and technology, the influence of electromagnetic wave radiation on the environment is increasing day by day. Such as: at an airport, airplane flights are mistakenly started because the airplane flights cannot take off due to electromagnetic wave interference; in hospitals, mobile phones often interfere with the normal operation of various electronic medical instruments. Therefore, the electromagnetic pollution treatment is combined with the silica gel sheet, and the silica gel sheet is arranged in the gap near the radiator to realize the wave absorbing effect.

However, the electromagnetic wave radiation source is usually accompanied by a heating phenomenon, the wave-absorbing silica gel sheet is very easy to be heated and heated, and the heat inside the silica gel sheet is difficult to be transferred out due to the fact that the wave-absorbing silica gel sheet is clamped in the gap, so that the service life is finally shortened.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a good ripples silica gel piece that absorbs wave dispels heat.

The utility model discloses a technical scheme that wave-absorbing silica gel piece adopted is inhaled in heat dissipation is:

a heat dissipation and wave absorption silica gel sheet comprises a silica gel body and a high-heat-conductivity base material, wherein one end face of the silica gel body is provided with criss-cross ventilation grooves which are all in a bent extending shape; the high heat conduction substrate is arranged on the end face, far away from the ventilation groove, of the silica gel body.

Preferably, the bottom of the ventilation groove is arc-shaped.

Preferably, the silica gel body is provided with a ventilation groove, and one end face of the silica gel body is coated with a metal powder layer.

Preferably, the heat-conducting silica gel further comprises wire-drawing fibers, and the wire-drawing fibers are arranged between the silica gel body and the high heat-conducting base material.

Preferably, one end of the high-thermal-conductivity base material is provided with a plurality of reinforcing ribs.

The utility model discloses a heat dissipation microwave-absorbing silica gel piece's beneficial effect is: criss-cross ventilation groove has been seted up to colloidal silica one end face, and ventilation groove all is crooked extension form. The high heat conduction substrate is arranged on the end face, far away from the ventilation groove, of the silica gel body. Absorb the heat of radiation source and go out through high heat conduction substrate, make the colloidal silica lateral wall can pass through the flowing air through vertically and horizontally staggered's ventilation groove, and then take away the heat of colloidal silica inside. The curved ventilation slot increases the contact area with air, so that the internal heat can be fully released.

The high thermal conductive substrate 20 is disposed on an end surface of the silicone body 10 away from the ventilation slot 11. The high heat conduction base material 20 absorbs heat of the radiation source, and the criss-cross ventilation grooves 11 enable the side wall of the silica gel body 10 to penetrate through flowing wind, so that heat inside the silica gel body 10 is taken away. The curved ventilation slot 11 increases the contact area with air, so that the heat inside the silicone body 10 can be fully released.

The bottom of the ventilation groove 11 is arc-shaped, so that the contact area with air is increased, and the heat in the silicon body 10 can be fully released.

The silicon body 10 is provided with a ventilation groove 11, and one end face of the silicon body is coated with a metal powder layer 30. Through the shielding effect of metal, the wave-absorbing colloidal silica 10 is assisted to shield overflowing radiation waves.

The embodiment further comprises a fiber drawing 40, wherein the fiber drawing 40 is arranged between the colloidal silica 10 and the high thermal conductivity base material 20. The good toughness of the drawn fiber 40 enhances the extrusion and stretching resistant effects of the whole structure.
