Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Figure 1 to Figure 3 Some examples shown are vacuum ovens for vacuum drying of batteries and supercapacitors. refer to Figure 1 to Figure 3 , the vacuum oven includes a box body 10 and a box door 20 . The innovative content is that on the basis of the existing vacuum oven, a heat insulation structure is added to achieve the purpose of reducing heat loss, avoiding the problem of poor thermal balance caused by heat dissipation, and reducing equipment maintenance costs.

[0021] For this reason, described vacuum oven also comprises several plate bodies 31,32, and described several plate bodies are covered on the inner surface of described box body 10 and box door 20 to form the radiation baffle plate 30 that blocks heat from radiating outwards, each The radiation baffle 30 is separated from the inner surfaces 11 and 21 by a certain distance so ...

Abstract

The invention provides a vacuum oven and a heat preservation method thereof. The vacuum oven is used for vacuum drying of a battery or a super capacitor; the vacuum oven comprises a box body, a box door and a plurality of plate bodies; the plurality of plate bodies cover the inner surfaces of the box body and the box door to form radiation baffles for prevent outward heat radiation; each radiationbaffle has a certain distance from the inner surface where the corresponding radiation baffle is positioned so that a heat insulating space is formed at the inner walls of the box body and the box door; and after the box body is internally vacuumized, the air in each heat insulating space is exhausted to form vacuum heat insulating layers. The heat preservation method comprises the following steps: the inner surface of the box body is provided with the radiation baffles for preventing outward heat radiation; and each heat insulating space is formed between the corresponding radiation baffle and the inner surface of the corresponding radiation baffle is positioned. The radiation baffles and the vacuum heat insulating layers form one or a plurality of heat insulating layers inside the box body, thus heat loss can be greatly reduced, the problem about poor heat balance caused by heat dissipation is prevented, and the maintenance cost of equipment is lowered.

Description

technical field [0001] The invention relates to battery vacuum drying equipment, more specifically to a vacuum oven and its heat preservation method. Background technique [0002] The main body of the lithium battery vacuum oven is made of stainless steel plate, which is mainly used to seal the cavity while ensuring sufficient strength so that the cavity and the sealing door will not be deformed by atmospheric pressure when the cavity is evacuated. But when the vacuum oven is working, if there is no heat protection, the surface of the stainless steel material, which is a good conductor of heat, will reach a very high temperature, resulting in a large loss of heat in the vacuum oven, and more seriously, it will affect the vacuum. The thermal stability in the oven causes the temperature of the lithium battery near the cavity and the sealed door to be low, resulting in uneven baking temperature of the lithium battery. Even if it is wrapped with thermal insulation cotton to pre...
