Embodiment Construction
[0012] The structural principle and working principle of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0013] see figure 1 , 2, the present invention includes a heat exchanger core 3 with a small-diameter intermediate channel 6 and a peripheral channel 7, and the intermediate channel 6 protrudes from the peripheral channel 7, and the peripheral channel 7 surrounds the intermediate channel 6, so that the intermediate channel 6 The fluid does not exchange heat with the environment, ensuring no loss of effective heat or cooling. At the same time, the fluid isolation structure can further ensure no loss of effective heat or cooling. The middle channel 6 and the peripheral channel 7 can be one or more rows of small-aperture channels 11. The two ends of the heat exchanger core 3 are respectively fitted with liquid collection tanks 1 and 5 communicating with the middle channel 6 and liquid collecting tanks 2 and 4 com...

A multi-channel plug-type heat returner which consists of the heat exchanger core and the liquor accumulating tank linked with the core as a whole. The heat exchanger core is made up of middle channel set with a small holes and exterior channel. The middle channel pops out from the exterior channel. At both side of the heat exchange core, a liquor accumulating tank with holes on one side communicating with the middle channel and a liquor accumulating tank with holes one both side communicating with the exterior channel, are sleeved outside in. The invention is adopted with a heat exchanger with several arrays of holes as the main heat exchanging body of the two kinds of flows enlarging heat exchanging area with this multi-hole structure so that the effecting heat will not leak in consequence of the exterior channel surrounding the inner channel. The heat exchanger core connects respectively with the one side holed water tank and the two side holed water tank effectively enhancing the system efficiency and the heat exchange without over enlarging the size of the system.
Description
technical field [0001] The invention relates to a regenerator, in particular to a multi-channel plug-in regenerator used in carbon dioxide supercritical cycle equipment for refrigeration, air conditioning and heat pump cycles. technical background [0002] With the complete prohibition of CFCs, carbon dioxide, as a natural working fluid with great potential to replace CFCs and HCFCs, has attracted increasing attention from various countries, and is currently widely used in refrigeration, air conditioning and heat pump circulation systems. If the working fluid has a greater subcooling degree before entering the throttle valve, it will improve the operating efficiency of the system and improve system performance; if the working fluid has a certain superheating degree before entering the compressor, it can be well protected compressor, while the regenerator can realize the subcooling of the working fluid before entering the throttle valve and the superheating of the working flu...
