Abstract
A radio heatsink, a radio unit, and a base station are disclosed. According to an embodiment, the radio heatsink (10) comprises a heatsink base (11) and a plurality of heatsink fins (12) extending from a first side of the heatsink base (11), wherein at least one portion (13) of the heatsink base (11) bulges at the first side toward the heatsink fins (12), a recess (14) opening to a second side of the heatsink base (11) that is opposite to the first side is formed at the portion (13), and the radio heatsink (10) further comprises a metal cavity filter (40) integrated with the heatsink base (11). According to another embodiment, the metal cavity filter (40) is separately formed and then inserted into the recess (14).
Claims13
A radio heatsink comprising:
- a heatsink base having a first side and a second side that is opposite to the first side;
- a plurality of heatsink fins attached to the first side of the heatsink base and extending in a direction away from the first side of the heatsink base, wherein at least a first portion of the heatsink base bulges in the direction in which the heatsink fins are extending, thereby forming a recess;
- and
- a metal cavity filter positioned within the recess of the radio heatsink.
A radio unit comprising:
- a radio board;
- a radio heatsink comprising a heatsink base having a first side and a second side that is opposite to the first side and a plurality of heatsink fins attached to the first side of the heatsink base and extending in a direction away from the first side of the heatsink base, wherein at least a first portion of the heatsink base bulges in the direction in which the heatsink fins are extending, thereby forming a recess;
- and
- a metal cavity filter positioned within the recess of the radio heatsink, wherein a first surface of the radio board is assembled with the heatsink base of the radio heatsink at the second side of the heatsink base.
A radio unit comprising:
- a circuit board having a first side and a second side opposite the first side, the first side of the circuit board having a first portion, a second portion, and a third portion;
- a heatsink comprising:
- a first portion having a first side and a second side opposite the first side, the first side of the first portion of the heatsink facing and abutting the first portion of the first side of the circuit board;
- a second portion having a first side and a second side opposite the first side, the first side of the second portion of the heatsink facing the second portion of the first side of the circuit board and spaced apart from the second portion of the first side of the circuit board by a distance of d units of distance, where d>0, thereby forming a gap between the first side of the second portion of the heatsink and the first side of the second portion of the circuit board;
- a third portion having a first side and a second side opposite the first side, the first side of the third portion of the heatsink facing and abutting the third portion of the first side of the circuit board;
- a first plurality of heatsink fins attached to the second side of the first portion of the heatsink;
- and
- a second plurality of heatsink fins attached to the second side of the third portion of the heatsink;
- and
- a metal cavity filter positioned in the gap between the first side of the second portion of the heatsink and the first side of the second portion of the circuit board.
