Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 illustrates a kind of regenerative heat exchanger, described heat exchanger comprises housing 16, heat storage medium 15, fluid passage, described heat storage medium 15 is positioned at housing 16, described fluid passage is positioned at heat storage medium 15, described fluid passage has fluid intake 17 and outlet 18, wherein along the flow direction of fluid, the heat storage capacity of described heat storage medium 15 raises gradually, namely the heat storage capacity of described regenerative heat exchanger is S, heat storage capacity S is set to the function of distance fluid intake x, i.e. S=f(x), in regenerative heat exchanger, f'(x) >0, wherein f'(x) be f(x) first order derivative.
If fluid is high temperature fluid, because along with the flowing of fluid, the temperature of fluid can decline gradually, also therefore its emission capacity reduces gradually, and progressively raised by the heat storage capacity of heat storage medium, the heat storage medium made overall accumulation of heat on fluid flow direction is even, avoids producing the uneven situation of accumulation of heat, thus the part affecting the uneven accumulation of heat caused of the inner accumulation of heat of regenerative heat exchanger too much is easily damaged.In like manner, if fluid is cryogen, along with the flowing of fluid, the temperature of fluid can raise gradually, also therefore its heat absorption capacity reduces gradually, and progressively raised by the heat storage capacity of heat storage medium, the heat storage medium made overall heat absorption on fluid flow direction evenly, is avoided producing the uneven situation of heat absorption.
Certainly, as preferably, along the direction of fluid flowing, the amplitude that the heat storage capacity of heat storage medium raises reduces gradually, i.e. f''(x) <0, wherein f''(x) be f(x) and second derivative.Because along the flowing of fluid, high temperature fluid temperature can be more and more lower, by setting like this, avoids fluid temperature (F.T.) to decline too fast, thus affect the uniformity of accumulation of heat.Prove by experiment, in this, set-up mode makes the accumulation of heat of storage heater more even.
Above-mentioned function do not represent that the heat storage capacity of heat-storing material is continually varying, and in fact the heat storage capacity of heat-storing material is change that can be discrete.Such as, the heat-storing material that described storage heater comprises comprises polylith, and such as, the left and right directions along Fig. 1 arranges polylith, and the heat storage capacity that arbitrary neighborhood is two pieces is different, and along the flow direction of fluid, the heat storage capacity of adjacent two pieces raises gradually.Further preferably, the amplitude of rising reduces gradually.This kind of situation be also included within above-mentioned function f (x) in.
As preferably, fluid passage outer setting fin, with augmentation of heat transfer.As preferably, along with the flow direction of fluid, the height of fin increases gradually.Because along with fluid flowing, fluid temperature (F.T.) constantly reduces, by the increase of fin height, make on the path of fluid flowing, the quantity of the heat radiation of unit length is substantially identical, thus reaches even accumulation of heat.
As preferably, along with the flow direction of fluid, the amplitude that fin increases is increasing.Found through experiments, overall accumulation of heat can be made more even by arranging like this.
