Patent ID: 8915293

Claim:
A heat exchanger, comprising: evaporator channels extending between a first end and a second end of said heat exchanger; condenser channels extending between the first end and the second end of said heat exchanger; a first connecting part and a second connecting part arranged at said first end and the second end, respectively, of said heat exchanger, the first connecting part and the second connecting part providing fluid paths between said evaporator channels and said condenser channels; a first heat transfer element arranged in a vicinity of said first end for transferring a heat load to a fluid in said evaporator channels; and a second heat transfer element arranged in a vicinity of said second end for transferring a heat load from a fluid in said condenser channels, wherein said evaporator channels and said condenser channels have capillary dimensions, wherein said evaporator channels and said condenser channels are arranged grouped together into at least a first group and a second group, each group including at least one evaporator channel and at least one condenser channel, wherein said first connecting part arranged at said first end of said heat exchanger comprises a first fluid distribution element arranged to conduct fluid from at least one predetermined condenser channel of said first group only into at least one corresponding predetermined evaporator channel of said second group, and wherein said second connecting part arranged at said second end of said heat exchanger comprises a second fluid distribution element arranged to conduct fluid from the at least one predetermined evaporator channel of said first group only into the at least one corresponding predetermined condenser channel of the first group.
