COOLING UNIT AND ELECTRONIC APPARATUS PROVIDED WITH THE SAME

PROBLEM TO BE SOLVED: To provide a cooling unit that can be downsized while enhancing cooling efficiency and obtain a low profile by a simple structure at a low cost, and to provide an electronic apparatus provided with the same. SOLUTION: This invention provides the cooling unit and the electronic apparatus provided with the same. The cooling unit is configured such that a contact heat exchange pump 7 is in contact with a heat generation electronic component 3 to transmit heat away from the electronic component 3 by the heat exchange action of a coolant inside the pump and a radiator 8 radiates the heat. A pump casing 15 of the contact heat exchange pump 7 is made of a material with high thermal conductivity, a heat receiving face 15a is formed at the side face of the pump casing 15 along an internal pump chamber 15b and the shape of the heat receiving face 15a at its contact position is formed to be complementary to the three-dimensional shape of the upper surface of the heat generation electronic component 3.
