Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
In an embodiment of the present utility model, as shown in Figure 1, provide a kind of Modular, semiconductor refrigerating plant, comprise combination framework 1, containing semiconductor chilling plate 2, fan and 4 mats 3 in combination framework 1.
Be arranged in the air channel of air conditioning for automobiles for the ease of combination framework, the size of combination framework 1 has certain restriction, and can regulate according to the size of different car duct, the width of preferred compositions framework 1 or diameter are lower than 5cm; This size not only can so that combo box body 1 be arranged near the blow-off outlet of former vehicle air conditioner duct system, and can ensure space and allow air-conditioning in former car can blow out hot and cold air from air channel.
Be provided with semiconductor chilling plate 2 in combination framework 1, semiconductor chilling plate 2 is divided into refrigeration end 6 and heat conduction end 9, and refrigeration end 6 temperature is low, and heat conduction end 9 temperature is high needs heat radiation.
The refrigeration end of semiconductor chilling plate 2 and heat conduction end are connected to cool guide sheet 5 and conducting strip, conducting strip can be aluminium flake, receive the refrigeration effect energy of semiconductor refrigerating end fast or receive the cooling effect energy of semiconductor chilling plate heat conduction end fast, the refrigeration effect of refrigeration end could be improved.
Between cool guide sheet 5 and conducting strip, be provided with the heat insulating mattress 7 for isolation of semiconductor cooling piece refrigeration end and heat conduction end, heat insulating mattress 7 can ensure the cold junction of semiconductor chilling plate and the isolation in hot junction, prevents exchange heat, improves refrigerating efficiency.
The two ends of combination framework 1 are provided with fan 4 and mat 3; Fan 4 can accelerate heat conduction refrigerating efficiency, and mat 3 can prevent foreign matter from invading and damage fan, and when protecting conduction cooling fan close to the person, can not damage people.
