Semiconductor coolers are a form of solid state cooling that incorporates both semiconductor Technologies and electronic assembly techniques. Cooling quickly, outstanding effect. Stable and practical. Easy to operate. in use. Refrigeration effect depends on the size of the cooling space, ambient temperature, heat insulation, seal ability, etc. Application for small space cooling, air cooling dehumidification, semiconductor refrigeration learning etc. size:175*100*98 mm Material: metal colour:black Package Contents: 1 * Semiconductor Refrigeration Cooler Only the above package content, other products are not included.
