1. A liquid cooling plate, having a first liquid cooling portion and a second liquid cooling portion that are perpendicular to each other, the first liquid cooling portion being located at a middle position of the second liquid cooling portion in a first direction, the liquid cooling plate comprising:
a first plate body having a one-piece structure, the first plate body comprising the first liquid cooling portion and a cover body portion of the second liquid cooling portion, the first plate body having a first flow channel of the first liquid cooling portion, the first plate body comprising a first part, a second part, a third part, and a fourth part that are bent consecutively, wherein the second part and the third part are arranged opposite to each other to form the first liquid cooling portion, the cover body portion is formed by the first part and the fourth part, the first part has an end connected to an end of the fourth part, the first part and the fourth part extend in opposite directions from the respective ends connected to each other;
a second plate body having a one-piece structure and being fixedly connected to the cover body portion, a second flow channel of the second liquid cooling portion being defined between the second plate body and the cover body portion, wherein the first flow channel is in communication with the second flow channel, and wherein the second plate body has a third flow sub-channel formed through stamping, the third flow sub-channel comprising a groove surface and a bottom surface, the bottom surface protruding in a direction away from a side of the cover body portion, and the second flow channel being defined by the third flow sub-channel and the cover body portion; and
a third plate body disposed at a side of the second plate body away from the cover body portion, the bottom surface of the third flow sub-channel being in contact with the third plate body, a thermal insulation passage being formed between the third plate body and a part, on which no second flow channel is formed, of the second plate body, and the thermal insulation passage being filled with a thermal insulation material, wherein:
the first plate body and the second plate body are in face-to-face contact and sealingly connected to each other at positions corresponding to the thermal insulation passage;
the liquid cooling plate has a fixation hole penetrating the second liquid cooling portion and formed at the second flow channel, wherein:
each of the first part and the fourth part has a sealing portion configured to form the fixation hole, the sealing portion extending towards a side close to the second plate body, and the second plate body having a passage hole for passage of the sealing portion; and
a seal is further disposed between the second plate body and the third plate body and configured to seal the fixation hole, the seal having an outer diameter greater than a diameter of the fixation hole at the third plate body.
