Surrounding type heat dissipation cold plate

The utility model relates to a surrounding type heat dissipation cold plate which comprises a sealing cover, an upper cover plate, a vertical face cold plate, a plane cold plate, a lower cover plate and an inlet and outlet connector. The end faces between the vertical face cold plates and the plane cold plates are welded, so that the heat exchange medium flow channels flowing in the longitudinal direction communicate with the heat exchange medium flow channels flowing in the transverse direction. The inlet and outlet connector is located on the lower cover plate and communicated with the transversely-flowing heat exchange medium flow channel, so that the heat exchange medium circularly flows. According to the utility model, the plates are formed by one-step welding through hanging materials. And the process difficulty of the product is greatly reduced, the welding deformation is reduced, and the yield of the product is improved. 本实用新型涉及一种环绕式散热冷板，包括封盖、上盖板、立面冷板、平面冷板、下盖板和进出口接头。立面冷板与平面冷板之间的端面焊接使得所述纵向流动的换热介质流道与所述横
