PURPOSE: A multi pipe type heat exchanger is provided to improve the assembling performance of a heat-transferring tube and improve heat transfer efficiency. CONSTITUTION: A multi pipe type heat exchanger comprises first and second header tanks and plural heat-transferring tubes(30). The header tanks comprises plate headers(11,21) each having plural heat-transferring tube insertion holes(13,23) and tanks(12,22) combined to the headers, and the headers installed oppositely. The ends of the heat-transferring tubes are inserted into the teat-transferring tube insertion holes. Rubbers(14,24) are formed to the heat-transferring tube insertion holes to guide insertion of the heat-transferring tubes.
