Abstract

The invention provides a refrigerant distributing device and a heat exchanger with the same. The refrigerant distributing device comprises a conduit, a first distributing pipe and a second distributing pipe, wherein the inner cavity of the conduit is divided into an upper cavity and a lower cavity; the first distributing pipe is provided with a gas phase refrigerant inlet and a gas phase refrigerant outlet and limits a first end inserted into the conduit and a second end extending out of the conduit; the gas phase refrigerant inlet is arranged in the upper cavity; the gas phase refrigerant outlet is arranged outside the conduit, with the opening downward; the second distributing pipe is provided with a liquid phase refrigerant inlet and a liquid phase refrigerant outlet and limits a first end inserted into the conduit and a second end extending out of the conduit; the liquid phase refrigerant inlet is arranged in the lower cavity; and the liquid phase refrigerant outlet is arranged outside the conduit, with the opening upward. The refrigerant distributing device has the following advantage: the gas phase and liquid phase refrigerants are mixed uniformly, thus the heat exchange efficiency is high.

Description

technical field [0001] The invention relates to a refrigerant distribution device and a heat exchanger with the refrigerant distribution device. Background technique [0002] In traditional heat exchangers, in order to improve heat exchange performance, a refrigerant distribution device is usually provided in the inlet header of the heat exchanger. For example, Chinese patent application CN101031762A describes a refrigerant distribution device in which a small-diameter conduit is provided in the inlet channel, wherein the inlet end of the small-diameter conduit is inserted into the liquid-phase fluid below the refrigerant gas-liquid interface in the inlet channel Inside, the outlet port is located outside the inlet channel. [0003] When the gas-liquid two-phase fluid flows in the inlet channel, gas-liquid stratification will inevitably occur, with the gas phase on top and the liquid phase on top. For the above conventional refrigerant distribution equipment, the inlet end...
