| description | The invention relates to a heat exchange structure efficient brazing constant-pressure loading device and a constant-pressure loading method.The device is composed of an insulating layer with through holes, disc spring constant-pressure sandwich plates and a rigid fastening tool, and an upper combined structure and a lower combined structure with disc springs serve as the constant-pressure sandwich plates to be placed between a multi-layer heat exchange structure and the rigid fastening tool; a plurality of through holes which are arranged in an array mode and used for installing heating electrodes are reserved in the fastening tool and the constant-pressure sandwich plate in advance, pressure control is conducted on the constant-pressure sandwich plate through the pressure adjusting screw rod, and the heating rates of different areas are controlled through electrode currents. The special constant-pressure clamping device is developed for a large-size complex heat exchanger through dot-matrix resistor extreme |
