Abstract
A magnetic resonance examination system comprises cooling clients (113, 144, 115) from which heat is carried-off by way of a system cooling circuit. A heat source (109) is in thermal contact with the system cooling circuit. A main pump (107) drives flow of the coolant in the system cooling circuit. The coolant is kept in motion and may be heated by the heat source. Thus, freezing of the coolant is avoided without the need of antifreeze. A back-up pump (121) of lower performance requirements may maintain flow of the coolant even if the main pump fails. A low viscosity coolant, such as water may be used. The system also contains a shut-off valve (127) and a short-circuit (141) parallel to the shut-off valve.
Claims10
A magnetic resonance examination system comprising:
- a cooling client;
- a system cooling circuit in thermal correspondence with the cooling client and in thermal correspondence with a heat drain;
- including:
- a main pump arranged in the system cooling circuit to drive fluid flow in the system cooling circuit wherein
- a heat source is arranged in thermal correspondence with the system cooling circuit
- a shut-off valve in the system cooling circuit and upstream or downstream of the cooling client and
- the system cooling system has a short-circuit parallel to the shut-off valve and a heat source is arranged in thermal correspondence with the short-circuit.
