Specific embodiment one:

[0029] Please refer to Figures 1-4 As shown, the present utility model is a modular computer room cooling wall, including a plurality of wall cooling modules 1, a main inlet pipe 2, and a main return pipe 3 installed on the wall, and also including a water chiller 4 and a circulation pump 5 placed outdoors. The water chiller 4 is a refrigeration device using water as a cooling medium, which takes away the indoor heat through a water circulation system, thereby achieving the purpose of reducing the indoor temperature.

[0035] Among them, a water inlet joint 91 is fixedly communicated with the lower end of the cold water inner tank 9. A water outlet joint 92 is fixedly communicated with the upper end of the cold water inner tank 9. An air guide groove 93 communicated with the upper end thereof is arranged on the back surface of the cold water inner tank 9. The width of the air guide groove 93 is the same as the distance between the outer walls of the two air duct side plates 82. A row of rectangular installation grooves 94 for placing the silent fan 10 are arranged on the inner bottom wall of the air guide groove 93. An air outlet channel 95 penetrating through the cold water inner tank 9 is arranged at the bottom of the rectangular installation groove 94. A ball valve 96 is installed on each of the water inlet joint 91 and the water outlet joint 92. Two insertion plates 97 which are in plug-in fit with the two positioning insertion rings 87 are fixed at the upper end of the cold water inner tank 9. The channel between the air guide groove 93 and the two air duct side plates 82 forms an air duct.

[0036] The wall mounting bracket 8 can be quickly installed on the wall through expansion bolts. The wall mounting bracket 8 and the cold water inner tank 9 are installed and positioned by means of upper-end plug-in and lower-end support, and lower-end positioning with the bolt-with-handle 86. The overall construction and installation are fast and convenient, and it is suitable for adding installation in an existing formed computer room.

[0037] Among them, in order to avoid condensation of the conveying water pipe, heat preservation pipes are respectively sleeved on the outer walls of the water inlet main pipe 2 and the return water main pipe 3.
