Abstract

The invention relates to a liquid cooling device for a computer, provided for a housing (1), enclosing a computer processor. In order to dissipate the heat by a radiant effect, the device advantageously comprises heat-removal means (20, 22, 23, 25) within the housing, attached to a lower wall (100), an upperwall (105) and at least one lateral wall (102, 103) of the housing (1). Each of the heat-removal means has two walls (P1, P2) at a separation from each other, made from a thermally-conducting material between which at least one circulation channel for a fluid is formed which is connected by a closed circuit (3) to at least one cooling element (61, 62, 63, 64, 65), attached to a power component in the computer. A pump (30), integrated in the circuit (3), circulates the fluid which permits a dissipation of the heat across the walls.

Dependent claims

A liquid cooling device for a computer, including heat-removal means (20, 22, 23, 25) attached to at least one wall (100, 102, 103, 105) to dissipate the heat by radiant effect, each of the heat-removal means including two spaced walls (P1, P2) made of a thermally-conducting material between which is formed at least one circulation channel (200) for a fluid, said channel 200 being linked to at least one cooling element (6) attached to an electronic component of the computer by a closed circuit (3) including a pumping device (30), Characterized in that:

each of the two walls (P1, P2) delimit the channel (200);
and
the walls (P1, P2) of at least one of the heat-removal means (20, 22, 23, 25) constitute an external wall (P1) and an internal wall (P2) of a housing (1) enclosing a computer processor, said heat-removal means (20, 22, 23, 25) being substantially spread out on the whole of the housing (1) to let the housing (1) play the role of heat exchanger with exterior.
