Claim 12:
13. A heat sink configured to be mountable on a cooling wall of a heat exchanger, the heat sink having coolant passageway configured such that coolant is flowable therethrough and comprising:
a coolant lead-in part configured to introduce the coolant into the coolant passageway;
a coolant lead-out part configured to discharge the coolant from the coolant passageway;
an upstream coolant-contact part in fluid communication with the coolant lead-in part;
a downstream coolant-contact part disposed spaced apart from the upstream coolant-contact part in a coolant path extending from the coolant lead-in part to the coolant lead-out part;
a first coolant-transit part disposed between the upstream coolant-contact part and the downstream coolant-contact part in the coolant path; and
first connecting parts respectively interposed between, and fluidly connecting, the first coolant-transit part and the upstream coolant-contact part and the downstream coolant-contact part;
wherein:
the upstream and downstream coolant-contact parts are configured to cause the coolant flow against the cooling-wall part, and
the first connecting parts each have a passageway cross-sectional area that is smaller than passageway cross-sectional areas of the upstream and downstream coolant-contact parts and of the first coolant-transit part.
