Cold beam equipment

The invention provides beam cooling equipment. The beam cooling equipment comprises a pressure self-balancing device, a static pressure box, a nozzle, an air return opening, a heat exchanger, an air supply opening and an air outlet device. The static pressure box comprises an air inlet cavity and an air outlet cavity, and a connecting wall is arranged between the air inlet cavity and the air outlet cavity; the air inlet cavity and the connecting wall are divided into the fixed section and the adjusting section through the pressure self-balancing device, the communication state of the fixed section and the adjusting section is controlled through the pressure self-balancing device, and therefore the air speed of the nozzle is controlled by opening or closing the adjusting section, air speed control over the indoor air supply outlet is achieved, and meanwhile noise generated when the air speed of the nozzle is too high is avoided. Furthermore, an air volume self-balancing device is additionally arranged, so that
