Embodiment Construction

[0034] The core of the present invention is to provide a heat exchanger capable of effectively, stably and reasonably distributing refrigerant, especially a kind of distribution for liquid or vapor-liquid two-phase refrigerant in the heat exchanger used as an evaporator. Through the distributor reasonably arranged and installed in the inlet header, the condensed and throttling refrigerant is reasonably distributed to the corresponding sets of flat tubes for heat exchange according to the heat exchange conditions of the heat exchanger.

[0035] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] figure 1It is a structural schematic diagram of a heat exchanger used as an evaporator in the present invention. In order to clarify the content of the view, most of the flat tubes and fins inside are...

Abstract

The invention discloses a heat exchanger, which comprises an inlet header, one side of the inlet header is provided with a plurality of interfaces for inserting flat tubes, and nozzles at one end of multiple sets of flat tubes pass through the interfaces Inserted into the inner cavity of the inlet header, the multiple groups of flat tubes are provided with micro-channels for circulating refrigerant; the heat exchanger is also provided with a distributor for refrigerant distribution, and the distributor is in the collection A part of the inner cavity of the header or the distributor is located on the lower side of the header in the inner cavity of the header. So that the refrigerant coming out of the distribution hole disperses the liquid refrigerant at the bottom of the inlet header and mixes with each other, so as to ensure that the refrigerant from the inlet header to the microchannels of each set of flat tubes is relatively uniform and stable , and make the distribution of refrigerant relatively reasonable, thereby improving the heat exchange efficiency of the heat exchanger.

Description

technical field [0001] The invention relates to the technical field of heat exchangers, in particular to a parallel flow heat exchanger used as an evaporator. Background technique [0002] A heat exchanger is a device that realizes heat transfer between cold and hot fluids, and is widely used in HVAC, refrigeration and other fields. [0003] The heat exchanger in the prior art generally includes a first header and a second header that are parallel to each other, and the two can usually be arranged in parallel to each other, and there are a plurality of heat exchange flats arranged in parallel between the two. tubes, and fins for fixed heat exchange are provided between the flat tubes for heat exchange. The first header and the second header are respectively provided with a plurality of interfaces for connecting with the flat tubes for heat exchange on the opposite tube walls, and the two ends of the flat tubes for heat exchange respectively pass through the interfaces for t...
