At least one of technical problem.
In order to achieve the above object, the technical solution adopted in the utility model is as follows：
A kind of vacuum drying oven, for the vacuum drying of battery or super capacitor, the vacuum drying oven includes babinet and chamber door,
The vacuum drying oven further includes several plate bodys, and several plate bodys are covered in the babinet and the inner surface of chamber door constitutes blocking heat
Measure the radiation baffle to external radiation, the inner surface at each radiation baffle and place is separated by a distance so that in the babinet
With formation insulated space at the inner wall of chamber door, it is true to be pulled out composition for the air of the insulated space after being vacuumized in the babinet
Empty thermal insulation layer.
In above-mentioned vacuum drying oven, it is preferable that the radiation baffle is at least towards the surface at the center of the babinet
Minute surface.
In above-mentioned vacuum drying oven, it is preferable that the radiation baffle includes one or more plate bodys, radiation baffle
Multiple plate bodys are stacked and spaced apart when including multiple plate bodys.
In above-mentioned vacuum drying oven, it is preferable that the thickness of the plate body is not more than 2mm.
In above-mentioned vacuum drying oven, it is preferable that the plate body is single layer thin plate or multi-layer thin plate body.
In above-mentioned vacuum drying oven, it is preferable that the radiation baffle is installed on the babinet by thermal insulating connectors
Respective inner walls.
In above-mentioned vacuum drying oven, it is preferable that adjacent radiation baffle is staggered.
Compared with prior art, the utility model at least has the advantages that：
Together with above-mentioned radiation baffle is formd with vacuum heat-insulating layer in babinet or several thermal insulation layer, case can be effectively prevented
Internal heat is transmitted outward by radiation mode and conduction pattern, so as to greatly reduce thermal loss, is avoided outside heat
The problem of thermal balance difference caused by dissipating, and babinet and chamber door are not in high-temperature condition, can reduce the maintenance of equipment at
This.
Description of the drawings
Fig. 1 is the structural schematic diagram of the babinet of some embodiment vacuum drying ovens；
Fig. 2 is its front view；
Fig. 3 is the structural schematic diagram of its chamber door.
Specific implementation mode
The utility model is described further with reference to the accompanying drawings and examples.
Vacuum drying of the Fig. 1 to some embodiment vacuum drying ovens shown in Fig. 3 for battery or super capacitor.Referring to Fig.1
To Fig. 3, the vacuum drying oven includes babinet 10 and chamber door 20.Innovative content therein be on the basis of existing vacuum drying oven,
Heat insulation structural is increased, to reach the problem and the reduction that reduce thermal loss, avoid thermal balance difference caused by being dissipated outside heat
The purpose of cost of equipment maintenance.
For this purpose, the vacuum drying oven further includes several plate bodys 31,32, several plate bodys are covered in the babinet 10 and case
The inner surface of door 20 constitutes blocking radiation baffle 30 of the heat to external radiation, the inner surface of each radiation baffle 30 and place
11,21 is separated by a distance so that the first insulated space 50 is formed at the inner wall of the babinet 10 and chamber door 20, when the case
The air that rear first insulated space 50 is vacuumized in body 10 is pulled out composition vacuum heat-insulating layer.
It can stop that heat is transmitted with radiation mode to outside babinet by radiation baffle 30, and can be with by vacuum heat-insulating layer
Blocking heat is transmitted with conduction pattern to outside babinet.It is above-mentioned to effectively prevent babinet using the heat-insulated principle with vacuum heat-insulation of baffle
Heat loss in 10, and then can ensure that babinet 10 and chamber door 20 are not in high-temperature condition, and avoid dissipating outside heat and draw
The problem of the thermal balance difference risen.
The radiation baffle 30 is minute surface at least towards the surface at the center of the babinet 10 as a preferred method,
(i.e. surface is smooth and smooth), to reach better heat insulation effect.
Further, the radiation baffle 30 includes two plate bodys 31,32, and two plate bodys 31,32 are stacked
And it is spaced apart.In this way, also forming the second insulated space between two plate bodys 31,32 for constituting radiation baffle 30
60, the air of second insulated space 60 is pulled out composition vacuum heat-insulating layer after being vacuumized in the babinet 10.Exist in this way
It is formed two layers of vacuum heat-insulating layer at the inner wall of babinet 10, preferably heat can be prevented to be transmitted outward with conduction pattern.
Under above-mentioned inspiration, it will be understood that can also be laminated with three or more plate bodys and compartment of terrain constructs radiation baffle, to be formed
More vacuum heat-insulating layers achieve the purpose that more preferably to prevent to dissipate outside heat.
The thickness for constituting the plate body of radiation baffle should be thin as possible, usually more than 2mm.
Alternatively embodiment, the plate body are the double-deck plate body or multilayer plate body of hollow-core construction, each plate body
A radiation baffle with insulated space can be separately formed.
Radiation baffle 30 described further is installed on the respective inner walls of the babinet 10 by ceramic connecting piece 40.
As a kind of more preferably embodiment, adjacent radiation baffle is staggered, can not only be made so above-mentioned heat-insulated
Space is connected to babinet, and the air that can be detached simultaneously when being vacuumized in babinet in insulated space forms vacuum heat-insulating layer,
And it can preferably stop that hot-air between insulated space and babinet, reaches better heat insulation again.
The heat preserving method of some embodiment vacuum drying ovens includes：Blocking heat is constructed in the inner surface setting plate body of babinet 10
To the radiation baffle 30 of external radiation；And between the radiation baffle 30 and inner surface 21 or 11 where it setting first every
Heat space 50 so that after being vacuumized in babinet 10, vacuum heat-insulating layer is formed in the inner wall of the babinet 10.
The heat preserving method of the vacuum drying oven further comprises using radiation baffle 30 described in minute surface thin-slab construction, with more
Good prevention heat outside radiation mode to dissipate.
