All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
An embodiment of a two-phase flow electric element radiator of the present invention, as shown in fig. 1 to 5, includes a heat radiating plate 100, a heat pipe 200, and a heat radiating fin 300.

The heat pipe 200 comprises a heat conducting section and two heat radiating sections, wherein the two heat radiating sections are arranged at intervals, and one ends of the two heat radiating sections, which are positioned on the same side, are respectively communicated with two ends of the heat conducting section; the heat pipes 200 are multiple, the heat conducting sections of the heat pipes 200 are distributed on the heat dissipation plate 100 along the first direction in sequence and are fixedly connected with the heat dissipation plate 100, the heat conducting sections of the heat pipes 200 are arranged along the second direction, and the lengths of the heat conducting sections of the heat pipes 200 are reduced from the center of the heat dissipation plate 100 to the corners in sequence. Preferably, the first direction and the second direction intersect but are not perpendicular, that is, the heat dissipation plate 100 has a rectangular structure, and the length of the heat conduction section of the heat pipe 200 is consistent with the width of each position on the heat dissipation plate 100 in the second direction, and the heat dissipation plate 100 having the rectangular structure enables the heat pipes 200 located at both sides of the heat dissipation plate 100 in the first direction to be staggered from each other.
The heat dissipation fins 300 are multiple, are sequentially distributed at intervals along the axial direction of the heat dissipation sections and are parallel to the first direction, the heat dissipation sections of the heat pipes 200 penetrate through the heat dissipation fins 300, and an external fan supplies air to the heat dissipation sections along the first direction.
By distributing the heat pipes 200 along the diagonal direction of the heat dissipation plate 100 and adapting the lengths of the heat conduction sections of the heat pipes 200 to the width of the heat dissipation plate 100, the heat dissipation sections of the heat pipes 200 are staggered in the first direction, so that the influence of mutual shielding on the heat dissipation of the fans caused by the mutual shielding is avoided; compared with the prior art, the heat pipe 200 is prevented from being blocked by the way of bending the heat dissipation section of the heat pipe 200, so that the bending times of the heat pipe 200 can be reduced, and the heat dissipation effect can be improved.
In the present embodiment, a side of the heat conduction section of the heat pipe 200 away from the heat dissipation plate 100 is locally pressed into a plane, and a side of the plurality of heat pipes 200 pressed into the plane is coplanar, so as to be attached to the electrical component, increase a contact surface between the heat pipe 200 and the electrical component, and improve heat conduction efficiency.
In the present embodiment, the diameters of the plurality of heat pipes 200 decrease in order from the center to the corners of the heat dissipation plate 100. The heat pipe 200 with the heat conduction section on the diagonal of the heat dissipation plate 100 is a central heat pipe, the diameter of the central heat pipe is the largest among the plurality of heat pipes 200, and the heat conduction section is the longest; the heat conduction section and the heat dissipation section of the central heat pipe are coplanar; the heat dissipation section of the other heat pipes 200 consists of an inclined section and a straight line section, the inclined section is connected with the straight line section and the heat conduction section of the heat pipe 200, the straight line section is parallel to the central heat pipe, and the inclined section is inclined relative to the central heat pipe; and one end of the inclined section connected with the heat conduction section is close to the central heat pipe compared with one end connected with the straight line section, and ensures that the flattened sides of the heat pipes 200 with different diameters are coplanar, and the central axis of the heat pipe 200 with smaller diameter is positioned at one side of the central axis of the heat pipe 200 with larger diameter, which is far away from the heat plate 100 (shown as 200a and 200c in fig. 6), when the heat pipe 200 is flattened at one side of the heat pipe 200, the heat pipe 200 with smaller diameter and the heat pipe 200 with larger diameter are overlapped to a certain extent in the diameter direction parallel to the flattening surface (shown as distance B in fig. 6), and compared with the heat pipes 200 with the same diameter and parallel distribution (shown as 200a and 200B in fig. 6), the distance between the heat conduction sections of the heat pipes 200 is smaller, so that the contact area of the heat pipe 200 to electrical components can be increased, and the heat conduction efficiency is further improved.
In this embodiment, the included angle between the heat conducting section and the side of the heat dissipating section, which is close to the heat dissipating plate 100, of the central heat pipe is not smaller than 90 °.
In this embodiment, the included angle between the heat conducting section and the inclined section, and the included angle between the inclined section and the straight line section of the other heat pipes 200 are not smaller than 90 ° except the central heat pipe. The heat pipes 200 are formed by bending a single pipe, the greater the bending degree is, the worse the heat conducting performance is, in order to reduce the size of the radiator, the included angle between different pipe sections of the heat pipe 200 is generally 90 degrees, but the bending radius between different pipe sections of the heat pipe 200 can be increased as much as possible, the diameter of the bending part is kept unchanged as much as possible, and the performance reduction effect caused by bending is reduced to the minimum.
In this embodiment, one end of the heat dissipation section of the heat pipe 200, which is far away from the heat conduction section, is a sealing structure.
