1. A cooling unit for cooling a heat generating component mounted on a printed wiring board, said unit comprising:
- a heat-receiving section which receives heat from the heat generating component and which opposes the printed wiring board across the heat generating component;
a heat sink thermally connected to the heat-receiving section and configured to release heat from the heat generating component; and
a cooling fan which applies cooling air to the heat sink, said cooling fan having a fan case and an impeller provided in the fan case, said fan case arranged side by side with the heat-receiving section along the printed wiring board and protruding from that side of the printed wiring board which faces away from the heat-receiving section.

Abstract
A cooling unit having a heat-receiving section, a heat sink and a cooling fan. The heat-receiving section opposes a printed wiring board across a heat generating component mounted on the board. The section receives heat from the heat generating component. The heat sink is thermally connected to the heat-receiving section. The cooling fan has a fan case. The heat-receiving section and the fan case are arranged, side by side, along the printed wiring board. The fan case protrudes from that side of the printed wiring board which faces away from the heat-receiving section.

9. A cooling unit for cooling a heat generating component mounted on a printed wiring board having a side, said unit comprising:
-
a heat-receiving section which receives heat from the heat generating component and which opposes the printed wiring board across the heat generating component;
a heat sink thermally connected to the heat-receiving section and configured to release heat from the heat generating component; and
a cooling fan which applies cooling air to the heat sink, said cooling fan having a fan case and an impeller provided in the fan case, said fan case arranged side by side with the heat-receiving section along the printed wiring board in such a way that a line passing the center of the heat-receiving section and extending in a direction in which the cooling fan and the heat-receiving section are arranged deviates from a line passing the center of the impeller of the cooling fan and extending in the direction in which the cooling fan and the heat-receiving section are arranged, and from the side of the printed wiring board toward the center thereof. - View Dependent Claims (10, 11, 12)

-
a housing;
a printed wiring board provided in the housing and having a side;
a heat generating component mounted on the printed wiring board; and
a cooling unit provided in the housing and configured to cool the heat generating component, said unit comprising;
a heat-receiving section which receives heat from the heat generating component and which opposes the printed wiring board across the heat generating component;
a heat sink thermally connected to the heat-receiving section and configured to release heat from the heat generating component; and
a cooling fan which applies cooling air to the heat sink, said cooling fan having a fan case and an impeller provided in the fan case, said fan case arranged side by side with the heat-receiving section along the printed wiring board, in such a way that a line passing the center of the heat-receiving section and extending in a direction in which the cooling fan and the heat-receiving section are arranged deviates from a line passing the center of the impeller of the cooling fan and extending in the direction in which the cooling fan and the heat-receiving section are arranged, and from the side of the printed wiring board toward the center thereof. - View Dependent Claims (18)
