  • Description: The utility model provides a flow division device for a heat exchanger, and the heat exchanger, and can solve the problem that liquid cannot be divided uniformly in the prior art. The technical scheme is that the flow division device for the heat exchanger comprises a liquid division pipe and a liquid divider which are integrally connected with each other; the liquid divider is provided with an inlet end and two outlet ends; the liquid division pipe is connected with the inlet end of the liquid divider; the connection end of the liquid division pipe and the liquid divider is a straight pipe; the straight pipe is vertically inserted into the inlet end of the liquid divider; the liquid division pipe is U-shaped; the liquid divider is Y-shaped; and the plane where the U-shaped liquid division pipe is positioned is vertical to the plane where the Y-shaped liquid divider is positioned. In the utility model, the liquid division pipe is vertically inserted into the liquid divider, and the plane where the liquid division pipe is positioned is vertical to the plane where the liquid divider is positioned, so when the liquid division pipe divides liquid to the liquid divider, the influence of gravity, centrifugal force, and other actions are avoided, the divided refrigerant liquid which enters the heat exchanger is uniform, and the whole heat exchange efficiency of the heat exchanger is improved; therefore, energy efficiency ratio is improved.
