Patent ID: 8050036

Claim:
A heat receiver for a liquid cooling unit, comprising: a casing including a planar thermal conductive plate as a part of the casing, the casing defining a flow passage formed between a top surface of the planar thermal conductive plate and a top plate of the casing, the casing defining a depression adjacent to the planar thermal conductive plate for establishing a space connected to an upstream end of the flow passage, the depression being at a level lower than the flow passage and extending across an entire width of the planar thermal conductive plate; at least one inflow nozzle extending into the space, each of the at least one inflow nozzle having a discharge opening facing the upstream end of the flow passage, the discharge opening having a lowest inner surface that is disposed below the top surface of the planar thermal conductive plate, the discharge opening having a highest inner surface that is disposed above the top surface of the planar thermal conductive plate; and an outflow nozzle extending into the casing, the outflow nozzle having an inflow opening; facing a downstream end of the flow passage, wherein the entire width of the planar thermal conductive plate is traverse to a flow direction of a coolant from the upstream end to the downstream end of the flow passage.
