When cooling tube 20, closure duct 40 can directly be compressed cooling tube 20 on longitudinal Z and on transverse direction H, be led without filling
Hot silicone grease, structure are simply conducive to product miniaturization, even more realize inner wall and the cooling fluid comprehensive engagement in closure duct 40, sufficiently
Using the inner wall area in closure duct 40 as heat exchange area, radiating efficiency, good heat dissipation effect, wherein in the present embodiment are improved
Longitudinal Z refer to closure duct 40 minimum internal orifice dimension direction, lateral H refer to closure duct 40 any other internal orifice dimension
Direction.Radiator (following abbreviation radiators) provided by the utility model for component heat dissipation, structure is simple and energy
Improve radiating efficiency, excellent in heat dissipation effect and the service life for improving convertible frequency air-conditioner.
In the present embodiment, it can be but be not limited to, be closed the outer tube diameter of longitudinal Z internal orifice dimension than cooling tube 20 in duct 40
Small 10%-20%, and since the lateral H internal orifice dimension in closure duct 40 is greater than or equal to the outer tube diameter of cooling tube 20, it can be and close
The lateral H internal orifice dimension for closing duct 40 is 0%-5% bigger than the outer tube diameter of cooling tube 20, guarantees cooling tube 20 on longitudinal Z and transverse direction H
It can be closed the inner wall slight squeeze in duct 40, but the tube wall face for being unlikely to cooling tube 20 generates fold, cooling tube 20 is not present
Accommodating the space of gas, that is to say, that the inner wall of cooling tube 20 is contacted with the cooling fluid of flowing, realizes that heat efficiently conducts,
Wherein, longitudinal Z in the present embodiment and transverse direction H is not limited to be direction signified in Fig. 2, and longitudinal Z refers to closure duct
40 minimum internal orifice dimension direction, lateral H refer to any other internal orifice dimension direction in closure duct 40.In addition, in order to avoid closing
The hole end margin for closing duct 40, which generates stress concentration to the outer tube wall surface of cooling tube 20, can destroy the outer tube wall surface of cooling tube 20,
Meeting carries out rounding or chamfered to the slot end margin of the first groove portion 11 and the second groove portion 31 in process.
