[0030] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] Please refer to Figure 1 - Figure 7 The utility model is a blown plate heat exchange component, comprising: at least one heat exchange plate 9, which is hollow and has openings at both ends along a first direction to form a heat exchange channel 10, at least one reinforcing block 13 is arranged on the inner wall of the heat exchange channel 10, at least one first protrusion 11 is distributed on both sides of the heat exchange plate 9 along a second direction, and the first direction and the second direction are perpendicular to each other along a vertical plane.

[0032] Specifically, the heat exchange plate 9 is in sheet shape, and the first direction can be any direction without specific limitation. The present application takes the first direction as a reference, which can be understood as the width direction of the heat exchange plate 9, and the second direction can be understood as the height direction of the heat exchange plate 9. By setting the heat exchange plate 9 hollow and opening both ends, the inside and outside of the heat exchange plate 9 can be separated to form a heat exchange flow channel 10 and a heat exchange channel for the flow of the cold source and the heat source, which can maximize the contact area between the cold source and the heat source and greatly improve the heat exchange efficiency.

[0033] During use, at least one reinforcing block 13 is arranged in the inner wall of the heat exchange channel 10 formed by the hollow heat exchange plate 9 and the openings at both ends along the first direction, which can not only play the function of reinforcing the structure, but also can push the inner walls on both sides of the heat exchange channel 10 away from each other, so that the heat exchange channel 10 will not be closed due to the influence of external force during use. At the same time, the reinforcing block 13 can also change the direction of the gas or fluid to improve the heat exchange efficiency; at least one first protrusion 11 is distributed on both sides of the heat exchange plate 9 along the second direction, which can also play the function of reinforcing the structure, and enable the outer surface of the heat exchange plate 9 to cooperate with the outer surface of other heat exchange plates 9 or the inner surface of the shell to form a heat exchange channel, and the heat source and heat source are exchanged through the heat exchange channel and the heat exchange channel 10, which can ensure that when the gas or fluid flows outside the heat exchange plate 9, the heat exchange channel outside the heat exchange plate 9 will not be closed due to the influence of external force. At the same time, the first protrusion 11 can also change the direction of the gas or fluid. This design method has a simple structure and greatly improves the heat exchange efficiency.

[0034] In one embodiment of the present invention, the heat exchange plate 9 is narrowed at both ends along the third direction to form a connecting plate 14, and the first direction and the third direction are perpendicular to each other along a horizontal plane.

[0035] Specifically, the third direction can be understood as the length direction of the heat exchange plate 9. The heat exchange plate 9 has connecting plates 14 on both sides, and the connecting plates 14 can be connected and limited with the shell with connecting grooves; and the connecting plates 14 are formed by narrowing the two ends of the heat exchange plate 9 along the third direction, which can increase the opening formed between multiple connecting plates 14, so that gas or fluid can circulate quickly, greatly improving the heat exchange efficiency.

[0036] In one embodiment of the present invention, there are multiple heat exchange plates 9, and the multiple heat exchange plates 9 are stacked along the second direction.

[0037] Specifically, by stacking the plurality of heat exchange plates 9 in the height direction, the cold source and the heat source can be fully diverted for heat exchange, and when stacked, the first protrusion 11 of the lower layer of the heat exchange plate 9 is just in contact with the first protrusion of the upper layer of another heat exchange plate 9, which can not only ensure the stability of the heat exchange component, but also further form turbulence for the passing gas or fluid. The structure is simple and stable, and the assembly is convenient while greatly improving the heat exchange efficiency.

[0038] In one embodiment of the present invention, at least one second protrusion 12 is distributed on both sides of the heat exchange plate 9 along the second direction, and the second protrusion 12 is staggered with the first protrusion 11 .

[0039] Specifically, by setting different protrusion structures, the flow direction of the gas or fluid can be changed, thereby improving the heat exchange efficiency; in the present application, the first protrusion 11 and the second protrusion 12 are staggered and distributed, which can separate the flow direction of the gas or fluid into multiple branches, prevent the accumulation of heat sources and cold sources, and greatly improve the heat exchange efficiency.

[0040] In one embodiment of the present invention, the number of the reinforcing block 13 , the first protrusion 11 and the second protrusion 12 are all multiple, and are symmetrically distributed in pairs along the axis of the heat exchange plate 9 .

[0041] Specifically, the reinforcing block 13, the first protrusion 11 and the second protrusion 12 are symmetrically distributed along the height direction of the heat exchange plate 9, symmetrically distributed in the width direction and / or symmetrically distributed in the length direction, so that the heat exchange channel 10 and the heat source and the cold source in the heat exchange channel can exchange heat more fully, greatly improving the heat exchange efficiency; and the reinforcing block 13 is symmetrical up and down, and can push the upper and lower layers of the heat exchange plate 9 away from each other, which can not only strengthen the heat exchange plate 9, but also ensure that the heat exchange channel 10 is not easily deformed by external forces and has better stability; through the symmetrical distribution of the first protrusion 11 up and down, multiple heat exchange plates 9 can be guaranteed to have a larger heat exchange channel when they are stacked, and the heat exchange channel is not easily deformed by external forces, and also has good stability.

[0042] In one embodiment of the present invention, two adjacent first protrusions 11 and a corresponding second protrusion 12 are arranged alternately in an isosceles triangle.

[0043] Specifically, Figure 6 As shown, the first protrusions 11 and the second protrusions 12 are arranged at intervals along the first direction, and the first protrusions 11 and the second protrusions are arranged alternately along the second direction. When arranged in the first direction, the number of the first protrusions 11 is n, and the number of the second protrusions 12 is n-1. The second protrusions 12 are staggered with the first protrusions 11, so that when arranged in the second direction, two adjacent first protrusions 11 and a corresponding second protrusion 12 are arranged in an isosceles triangle in an alternating manner, which not only ensures the stability of the heat exchange component, but also further forms turbulence for the passing gas or fluid. The structure is simple and stable, and the assembly is convenient while greatly improving the heat exchange efficiency.

[0044] In one embodiment of the present invention, the heat exchange plate 9 is blown integrally.

[0045] Specifically, the heat exchange plate 9 has a simple structure and is made by a blowing process. The bosses blown out can be used as heat exchange fins to improve heat exchange efficiency. The structure is also compact, avoiding the use of a relatively bulky structure, and there is no need to weld external fins.

[0046] Setting the heat exchange component to a compact structure can better adapt to the heat exchange needs of different scenarios, such as the recovery of heat from high-temperature flue gas in industry and the cooling of high-temperature gas in high-power density inverter boxes, thereby ensuring the normal operation of electrical components. Heat exchange between gases can be achieved through reasonable flow channel layout and fluid dynamics flow mode; the efficiency is greatly improved by the layer-by-layer staggered heat exchange between high-temperature fluid and low-temperature fluid; compared with traditional heat exchangers, it occupies less area and can meet the limited needs of airborne operations, while reducing energy losses and achieving efficient heat exchange. Miniaturized and lightweight materials are also more advantageous.

[0047] In one embodiment of the present invention, the first protrusion 11 is a circular protrusion, the second protrusion 12 is a strip-shaped protrusion, and the second protrusion 12 is arranged along the third direction.

[0048] Specifically, the gas or fluid can be separated by the circular first protrusion 11, and the gas or fluid can be gathered by the strip-shaped second protrusion 12 so as to be sent to the next first protrusion 11 for separation again. This can be repeated multiple times to prevent the accumulation of heat sources or cold sources and improve the heat exchange efficiency.

[0049] In one embodiment of the present invention, the first protrusion 11 and the second protrusion 12 are formed by bending from the inner side of the heat exchange plate 9 toward the outer side.

[0050] Specifically, the heat exchange plate 9 forms different flow channels through reasonable lamination, and the flow channels can efficiently exchange heat by reasonably arranging protrusions, and also have the function of strengthening the structure; the fluid forms turbulence in the heat exchange plate 9, has higher thermal efficiency, and can greatly improve the performance of the heat exchanger; the heat exchange plate 9 is mainly formed by blow molding, and there are three different types of protrusions in the heat exchange plate 9, namely the first protrusion 11, the second protrusion 12 and the reinforcing block 13. The reinforcing block 13 is used for heat exchange enhancement of high-temperature fluid between the heat exchange plates 9, and the first protrusion 11 and the second protrusion 12 are used for heat exchange enhancement of low-temperature fluid. The overall flow channel layout is reasonable and efficient; the present application can cool down high-temperature fluid while preheating low-temperature fluid, so it has more application scenarios; it can be used for flue gas heat exchange in industry and for high-temperature air cooling of inverter cabinets, which plays a role in energy saving and environmental protection.

[0051] On the other hand, the utility model also provides a heat exchanger, including a shell and the above-mentioned blown plate heat exchange assembly, wherein mounting grooves corresponding to the heat exchange plates 9 are arranged on both sides of the interior of the shell, and the heat exchange plates 9 cooperate with the mounting grooves along a first direction to form a first heat exchange channel, and the outer sides of each of the heat exchange plates 9 cooperate with the inner wall of the shell to form a second heat exchange channel, and the shell is connected to an external cold source and heat source respectively through the first heat exchange channel and the second heat exchange channel.

[0052] Specifically, the shell can be an integral structure or a detachable assembly structure. In the present application, the first shell 1, the second shell 2, the first side cover 3 and the second side cover 4 are detachably connected, so that the assembly of the heat exchanger is relatively simple, the overall heat exchanger and the heat exchange component are simple and efficient, and the complex processes of welding and threaded connections are reduced, the heat dissipation area is increased, the heat exchange efficiency is improved, the structure is stable, and the reinforced structure is evenly distributed. The structure is compact and simple, and the hot and cold flow channels are effectively and reasonably arranged, which can meet the needs of scenarios with limited space.

[0053] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
