Abstract

A cabinet for housing electronic equipment such as radio base station transceivers. The cabinet has one opening comprising at least one inlet section and at least one outlet section, a fan assembly and a baffle assembly arranged to force and direct an incoming air flow entering through the inlet section of the opening of the cabinet so it can pass through an electronic component storage area housing the electronic equipment and exit through the outlet section of the same opening in the cabinet.

First claim

1 . A thermal management cabinet for electronic equipment comprising:
a cabinet frame having side walls and defining a front, a back, a top and a bottom, the cabinet forming a generally sealed enclosure for electronic equipment; an electronic component storage area including at least one rack mounting assembly for supporting electronic equipment in an interior section of the cabinet; one opening in the cabinet comprising at least one inlet section and at least one outlet section; and a fan assembly and a baffle assembly arranged to force and direct an incoming air flow entering through the inlet section of the opening of the cabinet so it can pass through the electronic component storage area and exit through the outlet section of the same opening in the cabinet.

2 . A thermal management cabinet as in claim 1 wherein the cabinet further comprises a first and a second elongated compartment wherein the first compartment is arranged to guide the air flow upwards and the second compartment being adjacent to the first compartment is arranged to guide the air flow downwards.

3 . A thermal management cabinet as in claim 1 wherein the opening comprises one inlet section and two outlet sections and wherein the baffle assembly is further arranged to divide the incoming air flow received through the inlet section into two air flows so that each one of the two air flows can exit through one dedicated outlet section of the opening.

4 . A thermal management cabinet as in claim 1 wherein the inlet sections and outlet sections of the opening are separated by baffles on the outside of the cabinet.

5 . A thermal management cabinet as in claim 1 wherein the opening is located in the upper part of the cabinet.

6 . A thermal management cabinet as in claim 1 wherein the opening is located in the lower part of the cabinet.

7 . A base station comprising a thermal management cabinet as in claim 1 and transceiver equipment mounted in the electronic component storage area within the cabinet.
