<p>PURPOSE:To improve the heat exchanging performance in the heat radiating fins compared with the case in which the heat radiating fins are cooled only in the temp. of suction air by forming such an air flow passage that the air flow in the box body is made to flow from a suction opening to the cooling fins, the heat radiating fins, and to a discharge opening in order. CONSTITUTION:An electronic cooling element 10 which has an endothermic side and an exothermic side and absorbs heat in the endothermic side and generates heat in the exothermic side by energizing, cooling fins 11 provided in the endothermic side of the cooling element 10, heat radiating fins 12 provided in the exothermic side of the cooling element 10, and a blower 6 forming air fluw X are received the box body 1, 2 having an air suction opening 4 and a discharge opening 5. Such an air flow passage is formed in the box body 1, 2 that the air flow X is made to flow from the air suction opening 4 to the cooling fins 11, heat radiating fins 12 and the discharge opening 5 in order. As a result, the heat exchanging performance is improved compared with the case in which the heat radiating fins are cooled only in the temp. of suction air.</p> |
