PROBLEM TO BE SOLVED: To provide a cooler of which the cooling performance is prevented from being reduced.SOLUTION: An inflow port 41a of a flow channel is formed at a position where, when a coolant is made flow from the inflow port 41a into a flow channel 41, a total sum of flow vectors per unit volume of the coolant flowing from the inflow port 41a becomes rectangular to a length direction of the flow channel 41. The inflow port 41a is formed in contact with a heat transfer part 33 and an end wall surface of the flow channel 41 in the length direction and the inflow port 41a is formed in such a manner that its height becomes smaller than maximum depth of the flow channel 41. An outflow port 41b is formed at a position where, when the coolant is made flow from the inflow port 41a into the flow channel, a total sum of flow vectors per unit volume of the coolant passing through the outflow port 41b becomes rectangular to the length direction of the flow channel. The outflow port 41b is formed in contact with the heat transfer part 33 and the end wall surface of the flow channel 41 in the length direction, and the outflow port 41b is formed in such a manner that its height becomes smaller than the maximum depth of the flow channel 41.SELECTED DRAWING: Figure 2 |
