Description

Technical Field

[0001] The utility model relates to a heating module and a heating device comprising the heating module. Background Art

[0002] In the prior art, in order to heat shrink the heat shrink tube on the wire harness, the heat shrink tube must be heated evenly. If the heating is uneven, the quality of the wire harness product will be unqualified. The heating temperature and heating time are key factors in controlling the shrinkage quality of the heat shrink tube. However, in some heat shrink applications, due to the size of the tube, it is impossible to heat evenly. This will result in poor heat shrinkage quality of the heat shrink tube.
