Embodiment Construction

[0022] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0023] Including a cooling air pipe and a cooling air pipe, the two channels are not connected to each other, and each takes its own path. The cooling air duct is composed of 3 to 6 heat exchange units 5 with cold sides and pipes connected in series. In this embodiment, there are 5 heat exchange units. Each heat exchange unit is vertically spaced up and down, and the hot side The inlet and outlet ends are connected by the guide elbow 2 and are connected in series. The bottom end of the heat exchange unit is connected to the hot side inlet pipe 11, which is the hot side inlet end, and the uppermost heat exchange unit is the hot side end. The air outlet end is connected with the hot side air outlet pipe 10 to form a refrigerating air pipe; the heat exchange unit 5 is a plate-fin heat exchange unit, which includes a housing 12 and cold and hot side fins 20,...

Abstract

The present invention relates to an air-air heat exchanger choosing water and air as mixing working medium for refrigerating, which includes a refrigerating air pipeline and a cooling air pipeline. The refrigerating air pipeline is constituted by connecting the heat edge of a heat exchanging unit and a pipeline in series, the cold edge of the heat exchanging unit is connected to the cooling air pipeline. The differences between the two pipelines are that: the cooling pipeline is disposed with a water vapor atomizing chamber which is mounted with an atomizing nozzle connected to high pressure water source. The heat exchanging unit is plate fin heat exchanging unit disposed according to furcate-reverse flow heat exchanging mode. The cooling air pipeline is at negative pressure status. The present invention brings forward a design idea for refrigerating by choosing water and air as mixing working medium, the moisture absorption phase change step is design to be executed with high efficiency in the heat exchanger, and the medium transmission and heat transmission are synchronous, and good circulation is executed. The present invention is made as an air-air heat exchanger with high refrigerating function.

Description

Technical field [0001] The invention relates to an air-air heat exchanger for refrigeration using water and air as mixed working fluids, and belongs to the technical field of refrigeration and air conditioning. Background technique [0002] At present, most of the working fluids used for air-conditioning refrigeration are Freon. Although this type of air-conditioning has high refrigeration efficiency, it has the problem of environmental pollution. Whether a new harmless substance can be used to replace Freon for refrigeration and to have higher refrigeration efficiency is a difficult problem in the current refrigeration industry. [0003] In general air-to-air heat exchangers, low-temperature cold fluid flows through the cold side and exchanges heat with the heat exchanger fins on the cold side. The cold is transferred to the fins on the hot side through this, and the fluid flowing through the hot side is the same fin. The fins perform heat exchange to lower their temperature, ta...
