Liquid cooling heat exchange device and data center

A data center comprising a liquid-cooled server container (10) and a liquid cooling heat exchange device, wherein the liquid cooling heat exchange device comprises:

• at least a box body (1), a heat exchange component (2), a pump body (3), a filtering component (4) and a control box (5), wherein the heat exchange component (2) is provided with an internal liquid inlet (21), an internal liquid outlet (22), an external liquid inlet (23) and an external liquid outlet (24);
• the heat exchange component (2), the pump body (3), the filtering component (4) and the control box (5) are installed in the box body (1), the heat exchange component (2) is positioned between the pump body (3) and the filtering component (4), and the control box (5) is positioned directly above the pump body (3) or the filtering component (4);
• the internal liquid inlet (21) is communicated with one end of an internal liquid return pipeline (6), the pump body (3) is connected in series to the internal liquid return pipeline (6), the internal liquid outlet (22) is communicated with one end of the internal liquid inlet pipeline (7), and the filtering component (4) is connected in series to the internal liquid inlet pipeline (7);
• the external liquid inlet (23) is communicated with one end of an external liquid inlet pipeline (8), and the external liquid outlet (24) is communicated with one end of an external liquid return pipeline (9);
• and
• a projection of the internal liquid return pipeline (6), a projection of the internal liquid inlet pipeline (7), a projection of the external liquid inlet pipeline (8) and a projection of the external liquid return pipeline (9) on a plane where the pump body (3) and the filtering component (4) are on are positioned between the pump body (3) and the filtering component (4);
• wherein the other end of the internal liquid return pipeline (6) and the other end of the internal liquid inlet pipeline (7) are respectively communicated with an interior of the liquid-cooled server container (10).
