Embodiment 1

[0028] Such as image 3 As shown, the present invention provides a heat dissipation pipeline, which includes a pipeline body 9, and the pipeline body 9 is a refrigerant passage; the pipeline body 9 includes an ordinary pipe section 92 and at least one flexible pipe section 91, and the flexible pipe section 91 is at least in an expanded state Its inner diameter is larger than the inner diameter of normal pipe section 92 .

[0029] The flexible pipe section 91 can expand when the refrigerant flow rate increases, thereby increasing the heat dissipation area of ​​the heat dissipation pipeline. After the radiator is equipped with the heat dissipation pipeline, when the heat generation of the components increases, the flexible pipe section 91 is expanded by increasing the flow rate of the refrigerant, and the heat exchange area between the pipeline body 9 (refrigerant) and the heating components is increased, which greatly improves heat radiation.

Abstract

The invention provides a radiating pipeline, a radiator and a control method of the radiator, relates to the technical field of radiators, and solves the technical problem that an existing IGBT radiator is poor in radiating effect. The heat dissipation pipeline comprises a pipeline body, the pipeline body comprises a flexible pipe section, the inner diameter of the flexible pipe section is larger than that of a common pipe section at least in the expansion state, the flexible pipe section can expand when the flow of a refrigerant is increased, and therefore the heat dissipation area of the heat dissipation pipeline is increased. After the radiator is provided with the radiating pipeline, when the heating value of a component is increased, the flexible pipe section is expanded by increasing the flow of a refrigerant, the heat exchange area of the pipeline body and the heating component is increased, and the radiating effect is greatly improved.

Description

technical field [0001] The invention relates to the technical field of radiators, in particular to a heat dissipation pipeline, a radiator and a control method thereof. Background technique [0002] IGBT is an insulated gate bipolar transistor, which is a composite fully-controlled voltage-driven power semiconductor device composed of a bipolar transistor BJT and an insulated gate field effect transistor MOS. It has both high input impedance of MOSFET and low conduction of GTR. Advantages in terms of pressure drop. The saturation voltage of GTR is low, the carrying current density is large, but the driving current is large; the driving power of MOSFET is small, the switching speed is fast, but the conduction voltage drop is large, and the current carrying density is small. The IGBT combines the advantages of the above two devices, with low driving power and low saturation voltage. It is very suitable for the conversion system with a DC voltage of 600V and above, such as AC...
