Abstract
The present invention relates to an apparatus for supplying heat to directly cooled electronics. To ensure that directly cooled electronics are maintained at a temperature above 0° C., a circulation fan is provided in a transverse junction between an outlet duct and an inlet duct, for a recirculation flow of supplied cooling air, whereby outgoing hot air from the electronics, when necessary, may be mixed with the cold air, so as to raise the temperature of the cooling air to be supplied to the electronics.
Claims4
Apparatus for supplying heat at low temperatures to directly cooled electronics housed in an outdoor cabinet or the like, comprising:
- an inlet duct (9) for supply of outdoor air to the electronics;
- an outlet duct (10) for removal of the outdoor air, which is heated by the electronics;
- a transverse junction (12) arranged between the outlet duct (10) and the inlet duct (9) for possible recirculation of the outdoor air, which is heated by the electronics, from the outlet duct (10) to the inlet duct (9),
- characterised in that
- a one-way valve (11) is arranged in the outlet duct (10) to be opened under influence of the air pressure of the heated air acting on the valve, so as to discharge air from the outlet duct (10);
- and
- a speed controlled fan (13) is arranged in the transverse junction (12) to draw air from the outlet duct, and thereby control the amount of recirculated air to the inlet duct as well as the amount of discharged air leaving the outlet duct (10) via the one-way valve (11).
