Integrated radiator having temperature gradient

An integrated radiator having a temperature gradient disposed between a high-temperature device and a low-temperature device, comprising:

• a first heat dissipation unit and a second heat dissipation unit which are integrally fixed, wherein the first heat dissipation unit is configured to maintain the high-temperature device within a first temperature range, the second heat dissipation unit is configured to maintain the low-temperature device within a second temperature range, a thermal conductive path of the first heat dissipation unit is isolated from a thermal conductive path of the second heat dissipation unit, and the first heat dissipation unit is physically connected to but thermally separated from the second heat dissipation unit;
• wherein the first heat dissipation unit comprises a heat dissipation base and a heat dissipation plate which are integrally connected, a side surface of the heat dissipation plate facing away from the low-temperature device is kept in contact with the high-temperature device, and a temperature gradient of the first heat dissipation unit points to the heat dissipation plate from the heat dissipation base;
• wherein a connection portion is provided between the first heat dissipation unit and the second heat dissipation unit, and the connection portion is thermally separated from the heat dissipation plate through an insulating air gap;
• wherein one end of the connection portion is connected to the second heat dissipation unit, and another end of the connection portion is connected to the heat dissipation base.
