Problems solved by technology
First of all, the existing condensing units are generally in the form of upper air outlet, and the wind speed distribution on the side surface of the fin heat exchanger is uneven. In the heat exchanger, the gaseous state is transformed into a liquid state, while the mass flow rate of the refrigerant remains unchanged during this process, and the volumetric flow rate changes with the change of the refrigerant density, and the flow rate of the refrigerant in the heat exchanger changes
Therefore, the refrigerant flow rate is uneven and the cooling effect is poor.

Embodiment Construction
[0012] The present invention will be specifically described below in conjunction with the accompanying drawings and specific embodiments.
[0013] The structure of this embodiment is shown in the figure. The air collecting pipe of the present invention is divided into four primary air collecting pipes 1, the two primary air collecting pipes above are combined into one secondary air collecting pipe 2, the two primary air collecting pipes below are combined into one secondary air collecting pipe 2, and the two secondary air collecting pipes are combined into one secondary air collecting pipe 2. The trachea 2 is merged into a final gas collector. The final air collector flows out of the bottom loop of the fin heat exchanger. It is confirmed by the test operation of the unit that the heat transfer performance of the finned heat exchanger is obviously improved, and the operating efficiency of the unit is improved.

This invention relates to a fin type heat exchanger, it is used in air condition system for heat exchange. Big resistance loss and poor heat transfer effect in existing air condition is solved. The high efficiency fin heat exchanger includes several primary gas collectors, the special feature is that the primary collectors converge into at least two secondary collectors, and secondary collectors converge into final collector. The beneficial effect is that resistance loss is conquered, heat transfer efficiency is increased, cost is reduced, so it has good generalization value.
Description
(1) Technical field [0001] The invention relates to a finned heat exchanger, in particular to a high-efficiency finned heat exchanger suitable for an air-conditioning system. (2) Background technology [0002] In the high-efficiency condensing unit in the air conditioning system, the cold source comes from the atmosphere, and the fin heat exchanger, the key component, serves as a place for the air and refrigerator to exchange heat and cold. The heat transfer efficiency of the fin heat exchanger has a decisive impact on the performance of the unit. First of all, the existing condensing units are generally in the form of upper air outlet, and the wind speed distribution on the side surface of the fin heat exchanger is uneven. In the heat exchanger, the gaseous state is transformed into a liquid state, and the mass flow rate of the refrigerant remains unchanged during this process. The volumetric flow rate changes with the change of the refrigerant density, and the flow rate of...
