III. Product Overview

The high vacuum oven is used for moisture removal baking of lithium battery cells and electrode sheets. Compared with conventional ovens, it has advantages of stable performance, high vacuum level, short baking time, excellent dewatering and drying effect, and good pressure retention. It is combined with a dedicated high vacuum unit and cooling system to form an independent baking system, replacing conventional traditional ovens.

IV. Working Principle

Each machine can operate in continuous cycles; the basic process: open the door, place the cells or electrode sheets into the oven, then set the heating time, vacuum time, and nitrogen time. The system will automatically complete heating and timed gas exchange according to the preset time parameters, completing the baking process.

 

V. Product Features

High Vacuum Design

The internal chamber is made using pressure vessel standard welding process, with high vacuum retention, long durability, and no deformation.

Stable Temperature Uniformity

Temperature uniformity reaches ±3℃ under constant temperature.

Optimized Space Design

The internal chamber size can be customized according to the customer’s battery size, improving space utilization efficiency.

Precise Temperature Control

Temperature is controlled using silicon-controlled rectifier (SSR) + PID mode, with low thermal inertia and good control effect.

Heating Method

Hot air circulates both inside and outside the chamber, maintaining consistent internal and external chamber temperatures. Heat radiation and heat conduction ensure chamber temperature uniformity. During cooling, heating tubes are shut off, and internal heat is carried away by air circulation, accelerating cooling speed.

Sixfold Safety Protection

Ensures operational safety and product reliability.

Automated Program Control

PLC program controls heating, vacuuming, and nitrogen injection. Manual/automatic operation modes can be switched. Automatic timed heating is completed by simply setting heating time, vacuum time, and nitrogen time. The system will automatically perform baking and gas exchange.

Internal Airflow Structure

Uses magnetofluid circulation with good sealing and high temperature resistance.

Height 350mm × Width 850mm × Depth 1250mm (× 3 units)

External Dimensions

Height 2140mm × Width 2000mm × Depth 1400mm

Outer Shell Material

Double-Door Interlock Function

When one door is opened, the opposite door lights up and locks. Forcibly opening both doors will trigger an alarm and light prompt (effectively prevents cell trays from being pushed through and falling out the other side)

Vacuum and Nitrogen Charging Port Position and Interface Specifications

Interface position is at the rear of the equipment; vacuum interface is KF40, dry gas charging interface is φ12mm air pipe interface

 

VII. Vacuum and Temperature Control

Vacuum Degree

No-load chamber vacuum ≤10 Pa, full-load chamber vacuum: 50–100 Pa, leakage ≤500 Pa within 24 hours

Heating Method

Dual circulation of air internally and externally, dual heat source dual-control heating via thermal radiation, thermal conduction, and electric heating

External Heating Structure

U-shaped airflow; air is discharged from the left, drawn in from the right, with exhaust from top and bottom, achieving temperature uniformity

Main Heating Temperature Control

Temperature control accuracy within ±0.5℃

Chamber Temperature Deviation

±3℃ (empty box, constant temperature state)

Temperature Range

Room temperature +20℃ to 200℃

Heating Rate

Room temp to 85℃ ≤30 minutes (atmospheric pressure, no load; time for instrument to reach set temperature); internal chamber temperature stabilization time 60–90 minutes (no load); room temp to 85℃ ≤45 minutes (full load); internal chamber temperature stabilization time 90–120 minutes (full load)

Heating State

Temperature rises in a curve to the set value, then remains flat during constant temperature phase

Cooling Method

Cold air system connected to external airflow duct; alternating conduction cooling from outside the inner liner air duct; internal vacuum nitrogen is used for alternating cooling

Cooling Time

≤60 minutes (empty box, from 100℃ to 55℃, measured at core); full-load test time ≈120 min (depending on battery size and capacity)

Surface Temperature of the Chamber

When internal temp is 100℃, surface temp ≤ room temperature + 20℃

Independent Operation Per Layer

Each layer independently performs heating, vacuuming, and nitrogen charging

 

VIII. System Composition

1. The vacuum oven body mainly consists of sheet metal structure, heating system, circulation fan system, and software control system.

2. The auxiliary cooling system mainly consists of cooling exchange valves, cooling pipelines, and high-pressure fans, which cool the chamber from outside the working chamber.

3. The auxiliary cooling system is shared by three chambers, each independently controlled by valves.

4. The vacuum system consists of vacuum piping.
