Description

Heating board

Technical field

This utility model relates to a kind of heating board for vacuum drying oven, is mainly used in the drying of lithium battery.

Background technology

Existing vacuum drying oven, in being the wiring groove that resistance wire is embedded heating board, during Resistant heating, conducting heat to heating board, lithium battery is dried by heating board heat radiation, has air owing to being positioned at around the resistance wire of wiring groove, therefore the most aging during the long-time electrified regulation of resistance wire, and the heating board heating of this kind of structure is uneven, and insulating properties are poor, and service life is short.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of heating board, resistance wire is arranged between two-layer silica gel cloth, the most hot-forming, resistance wire is closed in silica gel cloth, will not oxidation by air, and the insulating heat-conductive characteristic due to silica gel cloth, uniformly, the baking needed time is short, good drying effect in heating board heating.

The purpose of this utility model is achieved in that

A kind of heating board, it is characterized in: described heating board includes the first silica gel cloth, resistance wire and aluminium sheet, described first silica gel is furnished with two pieces, resistance wire is arranged between two piece of first silica gel cloth, two piece of first silica gel cloth and resistance wire are by hot-forming, described aluminium sheet has two pieces, and the first silica gel cloth clamped by two blocks of aluminium sheets, and the point of incoming cables of described resistance wire is additionally provided with temperature controller.

This utility model one heating board, the edge of its aluminium sheet is provided with fixing hole.

This utility model one heating board, two blocks of aluminium sheets are outside equipped with the second silica gel cloth.

Compared with prior art, the beneficial effects of the utility model are:

1. this utility model one heating board, after two piece of first silica gel cloth is hot-forming, internal air is discharged, and stop extraneous air to enter, therefore, during resistance wire is in the environment of a vacuum, long-time heating also will not be aging, improves the service life of heating board；

2. this utility model one heating board, under the common effect of the first silica gel cloth and aluminium sheet, heating board surface heat is uniform, and hot face temperature and minimum temperature difference are at 2-3 DEG C, and therefore lithium battery dries quantity is good；

3. this utility model one heating board, during use, surface of aluminum plate of being fitted by lithium battery, the heat that resistance wire 3 sends conducts to lithium battery through the first silica gel cloth and aluminium sheet, and compared with existing heating board, drying time shortens 80%.

Detailed description of the invention

See Fig. 1-3, this utility model relates to a kind of heating board, it includes the first silica gel cloth 1, resistance wire 3 and aluminium sheet 4, described first silica gel cloth 1 has two pieces, resistance wire 3 is arranged between two piece of first silica gel cloth 1, the most hot-forming, two piece of first silica gel cloth 1 resistance wire 3 after hot pressing is closed in the first silica gel cloth 1, air will not be had to enter, described aluminium sheet 4 has two pieces, two blocks of aluminium sheets 4 clamp hot-forming after the first silica gel cloth 1, then it is bonded together, the point of incoming cables of described resistance wire 3 is additionally provided with temperature controller 5, temperature controller 5 instantaneous transmission temperature signal, the heating power of resistance wire can be adjusted according to specific needs.

The edge of described aluminium sheet 4 is provided with fixing hole, and this fixing hole is for the (see figure 3) that is arranged side by side of multiple aluminium sheets.

Second silica gel cloth 2 can also be set outside two blocks of aluminium sheets 4, further such that heating board surface heat is uniform.

Operation principle: after two piece of first silica gel cloth 1 is hot-forming, internal air is discharged, and stops extraneous air to enter, and during therefore resistance wire is in the environment of a vacuum, long-time heating also will not be aging, improves the service life of heating board；Under the common effect of the first silica gel cloth 1 and aluminium sheet 4, heating board surface heat is uniform, and hot face temperature and minimum temperature difference are at 2-3 DEG C, and therefore lithium battery dries quantity is good；Seeing Fig. 3, during use, aluminium sheet 4 surface of being fitted by lithium battery 6, the heat that resistance wire 3 sends conducts to lithium battery 6 through the first silica gel cloth 1 and aluminium sheet 4, and compared with existing heating board, drying time foreshortens to 80%.
