Cooling fan

BCR-4DM and BCR-12DM are direct cooling type, so there is only one cooling fan,
BCR-4DM is an 80×80MM cooling fan, and BCR-12DM is a 120×120MM cooling fan;
BCR-18DM and BCR-30DM are air-cooled, so there are two cooling fans inside and outside,
The outer fans are all 120×120MM cooling fans, the inner fan BCR-18DM is a centrifugal fan, and BCR-30DM is a bracket fan.
4. The conductive block, which conducts cold or heat energy, is made of aluminum and will not fail.
5. The control board is used to control the current direction. When the current direction changes, only the current on the cooling chip changes, and the current direction on the fan will not change. The function of the control board is to ensure the normal operation of the product. Shutdown; each model has its own control panel.

6. Toggle switch, BCR-12DM, BCR-18DM use toggle switch to switch between alternating current and direct current.
7. Switching power supply, divided into 4A and 6A switching power supply, one is used for BCR-4DM and BCR-12DM, the other is used for BCR-18DM and BCR-30DM, which are vulnerable parts.
8. The resettable temperature protector is a universal type.
