A heat exchanger comprises a heat exchange flat pipe and a collecting pipe. The heat exchanger can achieve the effect of uniformly distributing refrigerant while being used as an evaporator or a condenser so as to improve the heat exchange performance of the evaporator or the condenser. The collecting pipe comprises an upper collecting pipe wall, a lower collecting pipe and a splitter pore plate for uniformly shunting. A splitter pore is arranged on the splitter pore plate. The splitter pore plate is inserted between the upper collecting pipe wall and the lower collecting pipe and encircles to form an upper cavity and a lower cavity together with the upper collecting pipe wall and the lower collecting pipe. The refrigerant gas firstly enters into the lower cavity, enters into the upper cavity via the splitter pore and finally enters into a heat exchange flat pipe. The refrigerant gas flow entering into the heat exchange flat pipe is uniformly distributed due to shunting action of the splitter pore plate so that the uniform and full heat exchange effect is achieved and the overall heat exchange performance of the heat exchanger is improved.
