PURPOSE: To watch abnormal states in an atomic lamp container under high temperature environment by improving the cooling efficiency of a TV camera case.
CONSTITUTION: An inner case 7 and the finned outer case 8 of the case and the part other than cooling module are wholly made of aluminium, and a good heat insulating material 10 such as rock wool etc. is packet between the two cases. A window for lens in front of the case is doubly glassed. Heat of 27b, 27c transmitted from the outer case 8 to the inner case through the heat insulating material 10 is attracted again from the inner case to the cooling module, and consequently, does not come into the inner case. Accordingly, intrusion of heat into the inner case is made only through the double glassed window 20 in front of the case. The intruded heat 21 and heat generation of the camera 17 are transmitted to the inner case 7b and carried to the outer case 8b by the cooling module 9. Accordingly, cooling efficiency higher than conventional technique can be obtained by a cooling module having the same cooling capacity as used in conventional techniques.
