Embodiment Construction

[0024] From image 3 and Figure 4 It can be seen from the figure that the compact microchannel heat exchanger of the present invention includes a housing 1, on which the high-temperature fluid inlets and outlets 2 and 3 and the low-temperature fluid inlets and outlets 4 and 5 are respectively set, It is characterized in that: the shell 1 is provided with a plurality of channels stacked up and down the micro channel 6, the single layer high temperature fluid channel 7 on the micro channel 6 communicates with the high temperature fluid inlet and outlet 2 and 3, its double Several layers of low-temperature fluid passages 8 communicate with the low-temperature fluid inlets and outlets 4 and 5, and there are partitions between the high-temperature fluid passages 7, between the low-temperature fluid passages 8, and between the high-temperature fluid passages 7 and the low-temperature fluid passages 8. layer.

[0025] After the high-temperature fluid (such as refrigerant) flows in...

Abstract

The invention discloses a compact micro-passage heat exchanger comprising a shell which is respectively provided with an inlet and an outlet of the high-temperature fluid and low-temperature fluid and a micro-passage. The micro-passage is combined into an integral structure by a method that a high-temperature fluid passage, a low-temperature fluid passage and an interlayer between the high-temperature fluid passage and the low-temperature fluid passage are diffused by atoms. Compared with all existing micro-passage heat exchanger, the compact micro-passage heat exchanger has no thermal resistance generated by welding; the hydrodynamic diameter of the micro-passage can be designed freely; and the heat-transmission area in unit volume is more than 700. The micro-passage heat exchanger can be used as condensers, gas coolers or evaporators used by heat pump water heaters, heat pump boilers and geothermal heat pumps, can greatly improve the heat exchanging capability of the heat exchanger in unit volume, and can save the needed materials of the heat exchanger, thus reducing the volume and weight of the heat pump water heaters, heat pump boilers and geothermal heat pumps.

Description

Technical field: [0001] The invention relates to a compact microchannel heat exchanger for exchanging heat energy between a working fluid and a refrigerant, in particular to a condenser, a gas cooler or an evaporator used in heat pump water heaters, heat pump boilers and geothermal heat pumps, and belongs to heat transfer. heat transfer technology field. Background technique: [0002] Heat pump water heaters, heat pump boilers and geothermal heat pumps are all inseparable from heat exchangers, which put forward high requirements on the performance, size, quality and cost of heat exchangers. For the existing above-mentioned products, under the condition that the performance and quality are guaranteed, how to make the heat exchanger smaller, lighter, and lower cost has become the focus of technical research. Under the condition of a certain heat exchange capacity, the compactness of the heat exchanger means that the forced convection heat transfer coefficient of the working f...
