The invention provides a GPRS wireless data transmission method. a server is arranged in a server cabinet; the server cabinet is in a cuboid structure; a liquid storage cabinet containing refrigerantfluid is arranged on the top wall of the server cabinet; the bottom wall of the liquid storage cabinet accommodating the refrigerant fluid is communicated with two heads of a cavity with the two headsbeing cut-through; the cavity with the two heads being cut-through is arranged on the surface at the edge part in the server cabinet; fins are arranged inside the lower part of the cavity with the two heads being cut-through; integer variables and GPRS communication modules are arranged in a one-to-one correspondence manner; data received by the GPRS communication modules are packaged to form data packages; after the GPRS communication modules send the data packages to the server, the number of the data packages sent from the GPRS communication modules to the server is calculated by adoptinga data package number calculation program and is taken as a current value. According to the method, the defect in the prior art that a baseboard management controller is overwhelmed as tasks of the baseboard management controller are increased when a large number of information is sent to the baseboard management controller in a short time can be effectively avoided.
