<p>An apparatus to detect a leakage of a heat exchanger with at least one end of a pipe for an inlet or an outlet comprises: a fixing unit temporarily fixating the heat exchanger; a nozzle block closely located on the end of the pipe of the heat exchanger; a testing unit connected to the nozzle block measuring a pressure change by injecting or discharging a gas through the heat exchange; and at least one nozzle unit installed in the nozzle block to correspond to the end of the pipe. The nozzle unit is packed and connected to the end of the pipe by a relative access between the heat exchanger and the nozzle block.</p> |
