Abstract
The invention discloses a heat exchanger comprising a relatively sealed heat exchange chamber which is provided with more than two rows of heat exchange pipes communicated end to end in order. Each row of exchange pipe comprises more than one branch pipe. The branch pipes of adjacent two rows of heat exchange pipes are arranged staggered at intervals. The water outlets of the heat exchange pipes are arranged at the hot end of the exchange chamber, while the water inlets of the heat exchange pipes are arranged at the cold end of the exchange chamber. A heat source is arranged at the hot end of the exchange chamber. In the invention, the special arrangement of the heat exchange pipes makes hot airflow go forward in a wave shape in the heat exchange chamber and stay longer in the heat exchange chamber. Therefore, the hot airflow is heated more sufficiently. At the same time, the invention further adopts a special flame nozzle structure so that the sprayed flame is spherical, more uniform and combusted more sufficiently.
