Abstract
The utility model relates to a fin type heat exchanger. The utility model is used for air conditioning systems to exchange heat. The utility model mainly solves the defects of the existing heat exchanger that the resistance loss is large and the heat transferring effect is poor. The high-efficiency fin type heat exchanger comprises a plurality of primary air collection pipes. The utility model is characterized in that the primary air collection pipes are orderly combined into two secondary air collection pipes at least; the secondary air collection pipes are combined into a final air collection pipe. The utility model has the advantages that the resistance loss is overcome, the heat-transfer efficiency is improved, the production cost is reduced and the utility model has wide popularization value.
Description
(1) technical field under
The utility model relates to a kind of finned heat exchanger, particularly a kind of highly effective fin heat exchanger that is applicable in the air-conditioning system.
(2) background technology
High-efficiency condensation unit in the air-conditioning system, low-temperature receiver derives from atmosphere, and critical component finned heat exchanger wherein is as the place of atmosphere, the cold and hot exchange of refrigeration machine, and the heat exchange efficiency of finned heat exchanger exerts a decisive influence to unit performance.At first, existing condensation unit is generally the air-out form, and finned heat exchanger side surface wind speed distributes uneven, and heat exchanger middle part wind speed maximum weakens to the both sides wind speed gradually from the middle part; Secondly, because cold-producing medium changes liquid state into by gaseous state in finned heat exchanger, and refrigerant mass flow rate remains unchanged in this process, and volume flow rate changes with the variation of refrigerant density, and the flow velocity of cold-producing medium in heat exchanger changes.Therefore, cause the cold-producing medium flow velocity irregular, poor refrigerating efficiency.
(3) summary of the invention
The utility model provides the highly effective fin heat exchanger that a kind of Energy Efficiency Ratio is higher, production cost is lower in order to overcome the deficiency of above technology.
The utility model is realized by following measure:
Highly effective fin heat exchanger of the present utility model includes several elementary discharges, and its special feature is: described elementary discharge converges successively and is that it is a final stage discharge that at least two secondary discharges, secondary discharge converge.
Highly effective fin heat exchanger of the present utility model, described elementary discharge is preferably four, and described secondary discharge is preferably two.
As the finned heat exchanger of last air-out form, its side surface wind speed distributes uneven, and heat exchanger middle part wind speed maximum weakens to the both sides wind speed gradually from the middle part; In addition, because cold-producing medium changes liquid state into by gaseous state in finned heat exchanger, and refrigerant mass flow rate remains unchanged in this process, volume flow rate changes with the variation of refrigerant density, therefore, must cause drag losses in the running of cold-producing medium in finned heat exchanger in finned heat exchanger, influence heat conduction efficiency.The balance drag losses, is successively decreased discharge in discharge design of the present utility model successively according to the variation of cold-producing medium.
The beneficial effects of the utility model are, balance drag losses, improved heat transfer efficiency, reduced production cost, have very wide promotional value.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model
Among the figure, 1 elementary discharge, 2 level discharges, 3 final stage discharges.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is made specific description.The structure of present embodiment as shown in the figure.The utility model discharge sets up four elementary discharges 1 separately, and two elementary discharges of top are merged into a secondary discharge 2, and two elementary discharges of below are merged into 2, twice discharges 2 of a secondary discharge and merged into a final stage discharge.The final stage discharge flows out in the bottom loop of finned heat exchanger.Confirm that by this unit test run situation this finned heat exchanger heat transfer property obviously improves, unit operation efficient improves.
Claims (2)
1. a highly effective fin heat exchanger includes several elementary discharges, it is characterized in that: described elementary discharge converges successively and is that it is a final stage discharge that at least two secondary discharges, secondary discharge converge.
2. highly effective fin heat exchanger according to claim 1 is characterized in that: described elementary discharge is four, and described secondary discharge is two.
