Abstract: A system for cooling an auxiliary device having a main housing with at least one canister port, at least one fluid manifold mounted within the housing and in communication with the port, and a removable dry ice canister inserted in to the fluid manifold. Connected to the fluid manifold is a fluid line and connected to the canister is an air pressure line. Both the air pressure and fluid lines are connected to the pump. As the dry ice melts, it cools the fluid and creates pressure that activates the pump to pump fluid to the auxiliary device and back to the manifold for subsequent cooling.
