Description
Technical Field
The invention relates to the technical field of ocean nuclear power systems, in particular to a heat pipe heat exchange device.
Background
In a marine nuclear power system, a heat pipe is usually used for utilizing capillary force passive heat transfer as a reactor core heat conduction means, namely the heat pipe is inserted into a solid reactor core to form a heat pipe cooling reactor (called a heat pipe reactor for short), so that moving parts such as a unified loop main pump and the like can be omitted, the reactor core structure is greatly simplified, and the reliability is improved. The heat pipe is divided into an evaporation section, a heat insulation section and a condensation section, wherein the evaporation section is positioned in the reactor core body, and the heat insulation section and the condensation section are positioned outside the reactor core.
In the prior art, a heat pipe heat exchanger is usually arranged at a condensation section of a heat pipe, the surface of the heat pipe is directly flushed by a two-loop working medium, the heat pipe is cooled, and the heat of the heat pipe is taken away for subsequent work, but the heat exchange efficiency is not ideal. Therefore, in order to improve the heat exchange capacity, the heat exchange is enhanced by adopting measures such as adding fins on the surface of the heat pipe, but the method cannot be directly applied to the heat pipe pile.
The main reasons are that the outlet temperature of the heat pipe pile is usually above 600 ℃, if the power conversion system adopts water as working medium, phase change can occur in the heat exchanger, the volume of the working medium is suddenly increased, the flow rate is increased, and the heat pipe pile has high corrosiveness at high temperature, and if the power conversion system adopts gas working medium such as helium, supercritical carbon dioxide and the like, the ultrahigh flow rate can bring flow-induced vibration of the heat pipe. The power conversion system runs for a long time under the two conditions, and the hidden danger of heat pipe damage exists. In addition, the temperature of the cooling working medium is unevenly distributed due to uneven power distribution of the reactor, so that the flow loss of the working medium can be caused, and the vibration of the heat pipe is further aggravated. Moreover, the severe temperature rising condition of the working medium inlet and the strong heat exchange between the working medium and the heat pipe can cause abnormal complexity of the temperature field inside the heat exchanger, so that the expansion of structural members at all positions inside the heat pipe heat exchanger is uneven, and thermal stress and thermal damage of different degrees occur.

The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
Fig. 1 is a schematic longitudinal section structure of a heat pipe heat exchange device according to an embodiment of the invention. The heat pipe heat exchange device comprises a heat exchange body 1, wherein the heat exchange body 1 comprises a plurality of layers of substrates which are sequentially sleeved, mounting holes 10 for inserting heat pipes are distributed in each layer of substrates, heat transfer channels which are used for cooling working mediums to circulate and penetrate through the substrates are distributed around each mounting hole 10, and the cross sectional area of each heat transfer channel is gradually reduced from the innermost substrate to the outermost substrate of the heat exchange body 1. The substrate may be a cylindrical structure, for example, a cylindrical structure, or may be other structures, and embodiments of the present invention are not limited in particular. When the base body is of a cylindrical structure, the axis of the mounting hole 10 is parallel to the central axis of the base body. The heat pipe exchanges heat with the cooling working medium through the substrate.
The arrangement of the mounting holes 10 is the same as the arrangement of the heat pipes on the heat pipe stack 2 to be mounted correspondingly. For example, a typical heat pipe stack is formed by alternately inserting heat pipes and fuel rods into the holes of a "honeycomb" structure, and then the mounting holes 10 and heat transfer channels are also arranged in a "honeycomb" like hole arrangement.
Fig. 2 is a schematic diagram of an installation structure of a heat pipe heat exchange device and a heat pipe stack according to an embodiment of the invention. When in use, the heat pipe 3 is inserted into the mounting hole 10 and tightly combined with the mounting hole 10, so that the heat of the heat pipe 3 can be transferred to the substrate. The heat pipe 3 takes heat from the heat pipe stack 2 and transfers the heat to the substrates of each layer by means of heat conduction. The cooling working medium flows in from one end of the heat transfer channel close to the heat pipe pile 2, absorbs the heat of the matrix when flowing through the heat transfer channel, and flows out from the other end, so that the heat exchange between the heat pipe 3 and the cooling working medium is realized.
Because of the uneven radial power distribution of the heat pipe pile 2, the temperature of the heat pipe 3 on the heat pipe pile 2 is distributed in a cosine curve, so that the temperature of the heat exchange body 1 from the innermost matrix to the outer matrix is distributed in a corresponding curve. In the embodiment of the invention, the cross-sectional area of the heat transfer channel gradually decreases from the innermost substrate to the outermost substrate, a larger heat exchange area, a stronger heat exchange capacity and smaller flow resistance are obtained through a large passthrough, a larger flow speed is obtained through a small passthrough, and the heat exchange coefficient is improved. The flow and the cooling load of the cooling working medium in the heat exchange body 1 are gradually reduced from the innermost matrix to the outermost matrix in a gradient manner, namely, the middle large-flow cooling working medium is utilized to take away more heat load to the edge small-flow cooling working medium to take away a small amount of heat load, so that the heat exchange body 1 tends to be in uniform temperature distribution from the innermost matrix to the outermost matrix, each layer of matrix is subjected to uniform heat stress, stress damage caused by uneven expansion of the heat exchange body 1 is avoided, and the safety and reliability of the heat exchange device are improved.
According to the heat pipe heat exchange device provided by the embodiment of the invention, on one hand, the mounting holes 10 for mounting the heat pipes 3 and the heat transfer channels for circulating the cooling working medium are arranged in each layer of the substrate of the heat exchange body 1, so that the cooling working medium flows only in the special heat transfer channels and is not in direct contact with the heat pipes, and the heat exchange is performed through the substrate and the heat pipes 3.
Wherein the cross-sectional area of the heat transfer channels in the same matrix decreases gradually in a direction extending outwards from the centre. So that the heat exchange body 1 exhibits a more uniform temperature distribution in the direction extending outwards from the center. For example, the base body has a cylindrical structure, and the cross-sectional area of the heat transfer passage inside thereof gradually decreases from the center to the outside in the radial direction of the base body.
In the embodiment of the invention, in order to further even the temperature of each layer of matrix in the heat exchange body 1, the distribution density of the heat transfer channels in the heat exchange body 1 can be gradually reduced from the innermost layer of matrix to the outermost layer of matrix of the heat exchange body, so that the matrix with relatively higher temperature has relatively larger heat exchange area, the heat of the matrix with relatively higher temperature can be more effectively transferred to the cooling working medium, and the overall temperature distribution of the heat exchange body 1 is even.
FIG. 3 is a cross-sectional view of a heat pipe heat exchanger and a heat pipe after installation according to an embodiment of the present invention. In the embodiment of the present invention, six heat transfer channels are distributed around each mounting hole 10. Of course, the number of the heat transfer channels around the mounting hole 10 may be increased or decreased according to actual requirements, and embodiments of the present invention are not particularly limited.
As shown in fig. 1, the mounting hole 10 in the embodiment of the invention is a blind hole, so that the heat pipe 3 is not contacted with the cooling working medium outside the matrix after being mounted in the mounting hole 10, and the leakage of the working medium containing alkali metal in the heat pipe 3 into the cooling working medium is avoided, so that the cooling working medium damages components such as blades in the power generation device during subsequent work.
The degree of expansion of each layer of matrix is different, considering that the temperature of each layer of matrix is different. In the embodiment of the invention, the matrix from the innermost layer to the outermost layer is made of materials with gradient expansion coefficients, so that the whole heat exchange body 1 is uniformly expanded from inside to outside. In addition, the thermal stress born by the matrix at different temperatures is considered, the inner matrix at a higher temperature is made of a material with relatively high mechanical strength, the integrity and the safety of the heat exchange body 1 are ensured, and the outer matrix at a lower temperature is preferably made of a material with high thermal conductivity.
As shown in fig. 3, in the embodiment of the present invention, the heat exchange body 1 includes two layers of substrates, that is, an inner substrate 11 and an outer substrate 12, and the outer substrate 12 is sleeved on the outer side of the inner substrate 11. Wherein, the inner matrix 11 is in the high power region of the heat pipe pile 2, the outer matrix 12 is in the low power region of the heat pipe pile 2, the inner matrix 11 is provided with a first heat transfer channel 110, the outer matrix 12 is provided with a second heat transfer channel 120, and the cross section area of the first heat transfer channel 110 is larger than that of the second heat transfer channel 120. The inner matrix 11 adopts a large-diameter heat transfer channel, more heat load in the inner matrix 11 is taken away through a large-flow cooling working medium, meanwhile, the large-diameter heat transfer channel can increase the heat exchange area of the cooling working medium, improve the heat exchange capacity of the cooling working medium and reduce the flow resistance of the cooling working medium, the outer matrix 12 adopts a small-diameter heat transfer channel, less heat load in the outer matrix 12 is taken away through a lower-flow cooling working medium, and meanwhile, the flow speed of the cooling working medium can be improved through the small-diameter heat transfer channel, so that a higher heat exchange coefficient is obtained.
In the embodiment of the invention, the temperature of the inner matrix 11 is high, the temperature change of the cooling working medium from the inlet to the outlet of the heat transfer channel is large, and the expansion of the inner matrix 11 is large, so that the titanium alloy material with low expansion coefficient and high mechanical strength is adopted to limit the expansion and ensure higher reliability. The temperature of the outer matrix 12 is low, the temperature change of the cooling working medium from the inlet to the outlet of the heat transfer channel is relatively small, and the expansion of the outer matrix 12 is small, so that the stainless steel material with high heat conductivity is adopted. Therefore, the heat exchange body 1 structure with the inner matrix 11 with less expansion and higher strength and the outer matrix 12 with more expansion and higher heat conductivity is formed, the heat pipe 3 is more beneficial to transferring heat to the matrix and cooling working medium, and stress damage caused by uneven thermal stress of the inner matrix and the outer matrix is avoided.
In the embodiment of the present invention, the heat transfer channels in the inner matrix 11 are wavy along the flow direction of the cooling medium. The contact area between the cooling working medium in the inner matrix 11 in the high temperature area and the inner matrix 11 is further increased, and the heat exchange capacity of the cooling working medium is improved. The heat transfer channels in the outer matrix 12 are then provided as straight channels to achieve a lower flow resistance of the cooling medium. The wavy heat transfer channels are circumferentially and symmetrically distributed with respect to the center of the inner substrate 11, for example, when the inner substrate 11 is cylindrical, the wavy heat transfer channels in the inner substrate 11 are centrally and symmetrically distributed with respect to the axis of the inner substrate 11.
In the embodiment of the invention, as shown in fig. 1 and 2, an inlet distribution box 4 is installed at the working medium inlet 41 end of the heat exchange body 1, an outlet mixing box 5 is installed at the working medium outlet 51 end of the heat exchange body 1, a working medium inlet 41 and a through hole 42 are arranged on the inlet distribution box 4, the through hole 42 is used for inserting the heating pipe 3 into the mounting hole 10 after passing through, and a working medium outlet 51 is arranged on the outlet mixing box 5. The cooling working medium enters the inlet distribution box 4 from the working medium inlet 41, then enters the heat transfer channel to exchange heat with the heat pipe 3, enters the outlet mixing box 5 through the heat transfer channel to be mixed, and is discharged from the working medium outlet 51 for subsequent work. FIG. 4 is a cross-sectional view of a heat pipe heat exchanger and a heat pipe according to an embodiment of the present invention.
The inlet distribution box 4 and the outlet mixing box 5 can be welded and fixed with the end face of the heat exchange body 1 respectively, and can also be sleeved and fixed with the base body, such as a screw sleeve mode, and the sealing connection between the inlet distribution box 4 and the outlet mixing box 5 and the base body is ensured.
In the embodiment of the present invention, a plurality of working medium inlets 41 may be disposed on the inlet distribution box 4, the plurality of working medium inlets 41 are uniformly distributed on the side wall of the inlet distribution box 4, so that the cooling working medium enters the inlet distribution box 4 from a plurality of directions at the same time, and thus uniformly enters each heat transfer channel, and the working medium outlet 51 is disposed at the center of the end cover of the outlet mixing box 5.
