Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments, but it should not be understood that the scope of the subject matter of the present invention is limited to the following embodiments, and various modifications, substitutions and alterations made based on the common technical knowledge and conventional means in the art without departing from the technical idea of the present invention are included in the scope of the present invention.
The split-type multi-flow heat exchanger in this embodiment includes a heat exchange core and a core connection pipeline 5. The heat exchange core body is divided into a hot end heat exchange core body 8 (heating core body), a medium temperature end heat exchange core body 11 (heating/cooling core body) and a cold end heat exchange core body 1 (cooling core body). The heat exchange core body is formed by laminating a fluid channel and a cold plate, a medium temperature plate or a hot plate, and a fluid flow channel 13 is arranged in the cold plate, the medium temperature plate or the hot plate. The fluid flow channel 13 and the core connecting pipeline 5 form a closed, single-flow and non-flow-dividing loop. When the heat exchanger is used, heat transfer working media need to be filled in the closed loop, and liquid filling working media are selected according to the temperature range during use. Experiments show that compared with a low-liquid-filling-rate thermosiphon and a common heat pipe, the liquid-filling loop is a high-liquid-filling-rate two-phase thermosiphon, the equivalent heat conductivity coefficient is much higher, high heat flow density heat transfer can be realized, the self-driving force is strong, the situation that the liquid return of a separate heat pipe is difficult can not occur, the liquid-filling loop is suitable for long-distance heat transmission, and the gravity-resistant work can be realized.
When the heat exchanger works, the working medium in the flow channel 13 of the hot plate can generate bubbles due to heating, the working medium in the flow channel 12 of the medium-temperature plate can be partially liquefied due to cooling, and the working medium in the flow channel 12 of the cold plate can be liquefied due to cooling. The buoyancy of the bubbles and the pressure difference of the cold end, the middle temperature and the hot end drive the fluid in the pipe to circularly flow. At the moment, the pressure of fluid in the pipe fluctuates, the pressure fluctuation can accelerate bubble growth and break away from the wall surface at the heating end, the bubble annihilation and liquefaction can be accelerated at the medium-temperature end and the cooling end, and the micro-convection of the working medium is assisted, so that the purpose of strengthening phase change heat transfer is achieved, and stronger and farther heat transfer than that of a common heat pipe heat exchanger can be realized.
The flow channels 13 on the cold plate, the medium temperature plate and the hot plate and the core body connecting pipeline 5 form a closed loop. The core body connecting pipeline 5 is provided with a stop valve 4 for liquid filling. When in use, the liquid filling rate is 70-100% of the total volume of the closed loop formed by all the processed flow passages 13 and the core body connecting pipelines 5.
When the heat exchanger works, the use condition is that the medium-low temperature liquid filling working medium selects R134a, and the high temperature liquid filling working medium selects Nak alloy.
The heat exchange fins 12 are any one of offset fins, perforated sheets, or corrugated fins having slits and perforations.
As an option, two cold plates with the same flow channel 13, two medium temperature plates with the same flow channel 13 or a group of two hot plates with the same flow channel 13 are welded and formed, each layer of hot plate, medium temperature plate or cold plate is processed into the flow channel 13 with a semicircular section by using a chemical etching or machining method, the flow channels 13 are parallel to each other, the flow channels 13 are butted with each other in pairs according to corresponding positions, so that a second fluid channel and a third fluid channel of the first fluid flow channel are formed, wherein the adjacent flow channels 13 are connected through a bent pipe 14. The first fluid flow channel, the second fluid flow channel or the third fluid flow channel formed by the flow channels 13 is a single-flow channel and cannot be divided, and the first fluid flow channel, the second fluid flow channel and the third fluid flow channel are any one of a serpentine channel, a semi-elliptical channel and a plate-shaped channel.
The hot plate, the cold plate, the medium temperature plate and the core body connecting pipeline 5 are all rigid parts, and the rigid parts are made of metal materials selected from any one of copper, copper alloy, aluminum alloy, steel, titanium alloy or nickel-based high-temperature alloy.
The split heat exchanger in this embodiment is a completely novel split multi-stream heat exchanger, in which heat exchange ends are formed by combining heat exchange fins 12 and heat exchange plates (cold plates, medium temperature plates or hot plates), and are connected by pipelines, and the arrangement of the structural form is different from that of the conventional arrangement, and the liquid filling pipeline is different from that of the conventional heat pipe.
As shown in fig. 1, the heat exchanger is formed by connecting a hot-end heat exchange core body 8, a medium-temperature-end heat exchange core body 11, a cold-end heat exchange core body 1 and a core body connecting pipeline 5. Cold fluid flows through the cold end heat exchange core body 1 through the cold end inlet pipeline 2 and flows out through the cold end outlet pipeline 3 to form a cold fluid circulation channel. The medium temperature fluid flows through the medium temperature end heat exchange core body 11 from the medium temperature end inlet pipeline 9 and flows out from the medium temperature end outlet pipeline 10 to form a hot fluid circulation channel. The hot fluid flows through the hot end heat exchange core body 8 from the cold end inlet pipeline 6 and flows out from the hot end outlet pipeline 7 to form a hot fluid flow channel.
As shown in fig. 2, the hot-end heat exchange core 8, the medium-temperature heat exchange core 11, and the cold-end heat exchange core 1 are formed by stacking heat exchange fins 12 and hot plates, medium-temperature plates, or cold plate sheets of etching flow channels 13. The heat exchange fins 12 of the heat exchanger can adopt various fins, and need to be optimally designed according to the conditions of cold fluid, medium temperature fluid and hot fluid. The heat exchange fins 12 of the cold, medium and hot end heat exchange cores can be selected from different parameters.
As shown in fig. 3, fluid channels are required to be etched and processed in the cold plate, the medium temperature plate and the hot plate, a connecting pipeline interface is reserved, and finally a closed, single-flow and non-shunt fluid channel loop is formed by the cold plate, the medium temperature plate and the hot plate and the core body connecting pipeline 5.
It should be noted that only the main part of the present invention is illustrated in fig. 1, and other parts such as the fluid connection, the flow path sealing box, the fixing bracket, the baffle plate, etc. are omitted and not shown.
