Abstract

The invention relates to the technical field of heat exchange equipment, in particular to a liquid separation device for a heat exchanger and the heat exchanger, and aims to solve the problems that when a refrigerant enters a heat exchange pipe of an existing heat exchanger, gas-liquid two-phase mixing is not uniform, and the heat exchange effect is affected. In order to achieve the purpose, the liquid separation device for the heat exchanger comprises a liquid inlet pipe, a liquid separation component and a speed increasing component, the liquid separation component is provided with a mixing cavity, the mixing cavity communicates with the liquid inlet pipe, one end of the speed increasing component communicates with the mixing cavity, and the other end of the speed increasing component communicates with a heat exchange pipe of the heat exchanger; and the speed increasing component can enable the refrigerant in the mixing cavity to be quickly sprayed into the heat exchange tube. By means of the arrangement, when refrigerants enter the mixing cavity from the liquid inlet pipe, the gas-phase refrigerants and the liquid-phase refrigerants are evenly mixed, the gas-phase refrigerants and the liquid-phase refrigerants are prevented from being separated, the refrigerants in the mixing cavity are rapidly sprayed into the heat exchange pipes under the action of the speed increasing component, and therefore the heat exchange efficiency of the heat exchanger is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchange equipment, and in particular provides a liquid separation device for a heat exchanger and a heat exchanger. Background technique [0002] The existing heat exchanger still has the problem of low heat exchange efficiency. [0003] Taking the dry evaporator as an example, the conventional dry evaporator does not study the tube-side liquid separation carefully, which leads to the partial condensation effect of most dry evaporators and the relatively poor evaporation effect, which greatly wastes the performance of the heat exchanger. So that the heat exchanger can not give full play to its effect. [0004] In the existing dry evaporator, the refrigerant has two-phase separation at the inlet, which leads to uneven mixing of gas and liquid two phases when the refrigerant enters the heat exchange tube, which affects the heat exchange effect of the heat exchanger. [0005] Therefore, a new technic...
