Description
Technical field
The present invention relates to a kind of regenerator, particularly a kind ofly be applied to freeze, the multi-channel plug-in heat regenerator in the CO 2 supercritical recycle unit of air-conditioning and heat pump cycle.
Technical background
Along with comprehensive forbidding of CFCs, carbon dioxide is subjected to various countries day by day as a kind of natural refrigerant that has potentiality CFC alternative s and HCFCs and payes attention to, and is widely used at present in the middle of refrigeration, air-conditioning and the heat pump circulating system.If working medium has bigger degree of supercooling before entering choke valve, then can improve the operational efficiency of system, improve the performance of system; If working medium has certain degree of superheat before entering compressor, then can well protect compressor, and regenerator can be realized entering the mistakes cold-peace of working medium before the choke valve simultaneously and enters preceding overheated of compressor.But owing to consider the relation of regenerator, generally strengthen evaporator size or adopt gas-liquid separator to realize that the compressor dry-pressing is contracted and protect the compressor purpose of safe operation in traditional refrigeration system with this to systemic circulation efficient and physical dimension size.Adopt the system of carbon dioxide as refrigeration working medium, its kind of refrigeration cycle is to stride critical cycle, working medium is to cool off at gas cooler, and be different from traditional gas-liquid two-phase methods for cooling, it is postcritical single-phase cooling, can not enter the gas-liquid two-phase district, so the general employing parallel-flow heat exchanger that structure is more compact, heat exchange efficiency is higher, the sender property outlet temperature relatively approaches environment temperature.If adopt traditional cold way of mistake: do not adopt regenerator, make working medium cold excessively, not only increase quality and cost, and the sender property outlet temperature can not be lower than environment temperature, not reach predetermined effect but increase the gas cooler size.The operating pressure of carbon dioxide itself is very high, and flow resistance is little to the influence of cycle performance, is applicable to the channel-type regenerator that the aperture is less.In configuration aspects, traditional regenerator adopts sleeve pipe or shell-tube type, complex structure, and size is bigger, and is compact inadequately, and production and processing technology is also comparatively complicated, is difficult to realize, only is fit to apply to traditional working medium refrigeration system.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of and can strengthen heat exchange, reduce loss of refrigeration capacity, increase circulatory system efficient, dwindle physical dimension simultaneously, reduce the multi-channel plug-in heat regenerator of product cost.
For achieving the above object, the solution that the present invention adopts is: comprise heat exchanger core body and the catch box that is connected as a single entity with heat exchanger core body, be characterized in, said heat exchanger core body is made of the center-aisle of offering the small-bore and peripheral channel, and center-aisle protrudes in peripheral channel, two ends at heat exchanger core body are respectively installed with catch box that is connected with center-aisle and the catch box that is connected with peripheral channel certainly outside to inside, wherein the catch box that is connected with center-aisle is communicated with center-aisle by the one-sided perforate on the catch box, and one-sided perforate is identical with the cross-sectional sizes of center-aisle, and the catch box that is connected with peripheral channel is connected with peripheral channel by the bilateral perforate on the catch box, wherein the cross-sectional sizes of hole of the catch box that is connected with peripheral channel and heat exchanger core body is identical, and the outstanding center-aisle cross-sectional sizes of another hole and heat exchanger core body is identical.
The catch box that the present invention is connected with peripheral channel is the pipe of internal diameter greater than the thickness of heat exchanger core body; The catch box that is connected with center-aisle is the pipe of internal diameter greater than heat exchanger core body center-aisle thickness; Heat exchanger core body is by how row small-bore passages constitute up and down, and the aperture of every row's passage can be the same or different; Heat exchanger core body is flat type or bending type structure.
The present invention to have the main bodys of arranging the heat exchanger of small-bore channel design as two kinds of fluid heat exchange more, many rows small-bore channel design has increased heat exchange area, strengthen heat exchange, peripheral channel surrounds center-aisle simultaneously, the efficient heat or the cold of fluid in the center-aisle can not lost, heat exchanger core body communicates with bilateral perforate catch box and one-sided perforate catch box respectively and has solved the isolation of two kinds of fluids, can effectively improve system effectiveness and strengthen heat exchange, being unlikely the size that makes system again increases too many.
