Abstract
A cooling system, in particular for electronics cabinets, is proposed, comprising a casing, wherein the casing comprises at least a cabinet side partitionment, wherein the cooling system comprises a first cooling circuit and a second cooling circuit, wherein the second cooling circuit is an active cooling circuit, wherein the first cooling circuit and the second cooling circuit are thermally coupled, wherein the second cooling circuit is not disposed in the cabinet side partitionment.
Claims9
A cooling system for electronics cabinets, comprising:
- a casing including a cabinet side partitionment, a first cooling circuit, and a second cooling circuit,
- wherein the second cooling circuit is an active cooling circuit and the second cooling circuit is not disposed in the cabinet side partitionment,
- the second cooling circuit is a vapor compression cycle circuit and the second cooling circuit includes a combustible refrigerant with a Global Warming Potential (GWP) of less than 1,000,
- the first cooling circuit includes a heat absorbing heat exchanger section arranged in the cabinet side partitionment and a heat releasing heat exchanger section not disposed in the cabinet side partitionment,
- wherein the second cooling circuit includes a heat absorbing heat exchanger section,
- wherein the heat absorbing heat exchanger section of the second cooling circuit is thermally coupled to the heat releasing heat exchanger section of the first cooling circuit, such that heat absorbed from the heat absorbing heat exchanger section of the first cooling circuit in the cabinet side partitionment is transferred via the heat releasing heat exchanger section of the first cooling circuit outside the cabinet side partitionment to the heat absorbing heat exchanger section of the second cooling circuit, and
- wherein the cabinet side partitionment includes a partition wall separating the electronics cabinet and the cabinet side partitionment, the partition wall including one inlet opening for inflow of air from an interior of the electronics cabinet and an outlet opening for outflow of air into the electronics cabinet.
An electronics cabinet with a cooling system, comprising:
