Description
Technical field
The present invention relates to a kind of heat exchanger, particularly relate to a kind of discharge structure of heat exchanger.
Background technology
Usually, refrigerating circulation system comprises parts such as compressor, condenser, expansion valve and evaporimeter, and wherein condenser and evaporimeter are collectively referred to as heat exchanger, and the effect of heat exchanger is to carry out heat exchange with surrounding air.In heat exchanger, refrigerant is converted to gaseous state or is converted to liquid state by gaseous state by liquid state, neither endothermic nor exothermic in this process, thus reach the purpose of refrigeration or pyrogenicity.
Existing common heat exchangers can be divided into several types according to its design feature: the one, and ' finned tube ' formula heat exchanger, the design feature of the type heat exchanger is, the refrigerant pipe is provided with several cooling fins that is parallel to each other, and this heat exchanger is widely used as the evaporimeter of household appliances such as refrigerator and air-conditioner.The operation principle of ' finned tube ' formula heat exchanger is, when refrigerant flows through circulation refrigerant pipe, tube wall by the refrigerant pipe and cooling fin and surrounding air are carried out heat exchange, and cooling fin has increased the contact area of heat exchanger and surrounding air, has improved heat exchanger effectiveness.
The 2nd, plate heat exchanger is formed with certain refrigerant flow in the template pipeline of this heat exchanger, and when refrigerant flow through these refrigerant flows, the tube wall of template pipeline was by carrying out heat exchange with surrounding air.
The 3rd, miniature tubing heat exchanger in miniature tubing heat exchanger, comprising: isocon and several cooling fins of the female pipe of refrigerant inlet, the female pipe of refrigerant exit, several flat; Be formed with several miniature refrigerant flows in the isocon of described flat respectively, be arranged on evenly and at intervals between female pipe of refrigerant inlet and the female pipe of refrigerant exit, and make the two ends of each isocon be connected and be communicated with the female pipe of refrigerant exit with the female pipe of refrigerant inlet respectively.During heat exchanger work, refrigerant flows into from female pipe that enters the mouth, and is incorporated into the female pipe of refrigerant exit through each diverter then, flows out through the outlet of the female pipe of refrigerant exit.
More particularly, as depicted in figs. 1 and 2, existing miniature tubing heat exchanger comprises: the female pipe 1 of inlet, the female pipe 2 of outlet, flat isocon 3 and cooling fin 4; The female pipe 1 of described inlet be arranged in parallel in opposite directions with the female pipe 2 of outlet, and the inlet of the female pipe 1 of inlet is connected with the outlet of the compressor of refrigerating circulation system or the outlet of expansion valve, and the outlet of the female pipe 2 of outlet is connected with the inlet of the compressor of refrigerating circulation system; Described isocon 3 is arranged between female pipe 1 of inlet and the female pipe 2 of outlet evenly and at intervals, and is perpendicular with the female pipe of the female pipe 1 of inlet and outlet 2 respectively and be connected; Described cooling fin 4 undulates are arranged between each isocon 3, and its wave crest point contacts with the tube wall of isocon 3 respectively.
The female pipe 1 of described inlet is the identical pipe of diameter with the female pipe 2 of outlet, is formed with the installing port (not shown) that is used for inserting and welding each isocon 3 uniformly at interval on its tube wall.
Be formed with the miniature refrigerant flow that several are used for shunting refrigerant in the described flat isocon 3, these miniature refrigerant flows connect flat isocon 3.
Described cooling fin 4 is that to utilize the alternating bending of strip thin aluminum sheet to form corrugated, and each wave crest point of cooling fin 4 is welded on respectively on the tube wall of flat isocon 3.
The course of work when below above-mentioned existing miniature tubing heat exchanger being used as evaporimeter is illustrated:
The female pipe 1 of inlet of the gas-liquid mixed attitude refrigerant inflow evaporator of discharging from compressor divides to flow into each flat isocon 3 then, converges to the female pipe 2 of outlet by the miniature refrigerant flows in each the flat isocon 3.
In this process, liquid refrigerants carries out heat exchange by the tube wall and the cooling fin 4 of flat isocon 3 with surrounding air, from surrounding air, absorb heat, ambient air temperature is descended, reach cooling effect, the liquid refrigerants that meanwhile absorbs heat is gasified, and the inlet of compressor is given in the outlet loopback of refrigerant through exporting female pipe 2 that is converted to gaseous state.Said process constantly circulates, thereby reaches cooling effect.
But above-mentioned existing miniature tubing heat exchanger has following shortcoming: as illustrated in fig. 1 and 2, female pipe 1 of its inlet and the female pipe 2 of outlet vertically are provided with, and flat isocon 3 is along continuous straight runs settings.In the course of the work, the condensed water that is condensed in above the flat isocon 3 can not all successfully flow away, thereby forms frost, proceeds heat exchange thereby can influence between heat exchanger and the surrounding air, finally causes effectiveness of heat exchanger to descend.
Summary of the invention
