Circulation cooling device of acceleration sensor

A circulation cooling device of an acceleration sensor comprises a plurality of hollow cooling aluminum blocks, a cooling water tank, a circulating pump and a radiator which are connected in sequence through connecting pipelines to form a circulation cooling return circuit. The acceleration sensor is adhered to the surfaces of the hollow cooling aluminum blocks which are connected with the radiator through water pipes, the radiator performs circulation cooling to water in the cooling water tank through a radiating fin assembly under the action of the circulating pump, and two fans jointly perform auxiliary cooling to radiating fins. In addition, the water flowing speed can be changed and cooling efficiency can be controlled by adjusting opening degree of a valve. The circulation cooling device of the acceleration sensor can not only be suitable for acceleration acquisition at a high-temperature position of an exhaust system of a finished automobile test or an engine pedestal test, but also is convenient to in
