Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a multi-layer staggered fin heat exchanger. Background Technology

[0002] A heat exchanger is a device used to transfer heat from one fluid to another while ensuring that the two fluids do not come into direct contact. It is widely used in a variety of industrial and commercial processes, including but not limited to refrigeration, air conditioning, power plants, chemical production, and food processing.

[0003] In existing heat exchangers, when fins are used for heat exchange, the fins are usually arranged on the outside of the heat exchange tubes or heat exchange box. However, the fin design makes the arrangement of the heat exchange tubes insufficiently compact, which affects the heat exchange effect. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-layer staggered finned heat exchanger to solve the problem mentioned in the background art that when heat exchangers on the market use fins for heat exchange, the fins are usually arranged on the outside of the heat exchange tubes or heat exchange box. However, the fin design makes the arrangement of the heat exchange tubes not compact enough, which affects the heat exchange effect.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-layer staggered finned heat exchanger, comprising a heat exchanger body, a first fluid tank on the heat exchanger body, and rotary fluid tanks symmetrically connected to both ends of the first fluid tank, a second fluid tank evenly spaced inside the first fluid tank, and sealing insertion interfaces fixed at both ends of the second fluid tank, which are tightly inserted into the first fluid tank and the rotary fluid tank respectively, and upper heat exchange fins and lower heat exchange fins fixed at the upper and lower ends of the second fluid tank respectively, with adjacent upper and lower heat exchange fins staggered.

[0006] Preferably, the first fluid tank has a first fluid inlet / outlet connection cover sealed to the other two opposite sides, and the first fluid inlet / outlet connection cover has a flange connection structure.

[0007] Preferably, the dimensions of the second fluid box are the same as the internal dimensions of the first fluid box, and the gap between the second fluid boxes is greater than the height of the upper heat exchange fins.

[0008] Preferably, the upper heat exchange fins and the lower heat exchange fins are of the same corrugated structure, and each plane of the upper heat exchange fins and the lower heat exchange fins is perpendicular to the upper and lower surfaces of the second fluid tank.

[0009] Preferably, the distance between the upper heat exchange fins and the lower heat exchange fins is less than the width of the corrugated structure of the upper heat exchange fins.

[0010] Preferably, the rotary fluid tank is sealed with second fluid inlet and outlet pipe fittings at the upper and lower ends of its side, and a partition is also sealed and snapped into the rotary fluid tank. Furthermore, the rotary fluid tank and the second fluid tank are connected by the partition to form an S-shaped flow channel.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: This multi-layer staggered finned heat exchanger designs the heat exchange fins with a wave-shaped structure and staggers adjacent heat exchange fins in the upper and lower layers, which effectively increases the heat exchange area, while maintaining a compact structure and increasing turbulence to ensure efficient heat exchange. The multi-layer staggered finned heat exchanger also allows for overlapping areas between the staggered upper and lower heat exchange fins, effectively enhancing fluid turbulence and extending the fluid flow path, thus ensuring sufficient heat exchange.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: a multi-layer staggered finned heat exchanger, including a heat exchanger body 1, a first fluid tank 2 on the heat exchanger body 1, and first fluid inlet / outlet connection covers 201 sealed to the other two opposite sides of the first fluid tank 2, with flange connection structures. This structure allows the first fluid tank 2 to be connected via the flange structure on the first fluid inlet / outlet connection covers 201 for fluid inlet / outlet processing. The fluid in the first fluid tank 2 flows between multi-layered second fluid tanks 3, and the heat exchange effect is enhanced by the upper heat exchange fins 4 and the lower heat exchange fins 6. The first fluid tank 2 has two ends... A symmetrically connected rotary fluid tank 5 is provided. Second fluid tanks 3 are evenly spaced within the first fluid tank 2, and each of the second fluid tanks 3 has a sealing interface 301 fixed at both ends. The sealing interfaces 301 are tightly inserted into both the first fluid tank 2 and the rotary fluid tank 5. Upper heat exchange fins 4 and lower heat exchange fins 6 are fixed to the upper and lower ends of each second fluid tank 3, respectively. The dimensions of the second fluid tanks 3 are the same as the internal dimensions of the first fluid tank 2, and the gap between the second fluid tanks 3 is greater than the height of the upper heat exchange fins 4. This structure ensures reliable positioning of the second fluid tanks 3 and prevents contact between the upper second fluid tank 3 and the lower upper heat exchange fins 4, thus avoiding any impact on heat exchange efficiency. As a result, the upper heat exchange fins 4 and lower heat exchange fins 6 at adjacent positions are staggered. The upper heat exchange fins 4 and lower heat exchange fins 6 have the same wavy structure, and each plane of the upper heat exchange fins 4 and lower heat exchange fins 6 is perpendicular to the upper and lower surfaces of the second fluid tank 3. This structure, through the wavy structure of the upper heat exchange fins 4 and lower heat exchange fins 6, can increase the turbulence of the fluid and effectively improve the heat exchange effect. The staggered arrangement between the upper heat exchange fins 4 and lower heat exchange fins 6 can effectively increase the height of the upper heat exchange fins 4 and lower heat exchange fins 6, while keeping the internal structure of the heat exchanger body 1 compact, and ensuring the heat exchange effect. The spacing between the upper heat exchange fin 4 and the lower heat exchange fin 6 is smaller than the width of the corrugated structure of the upper heat exchange fin 4. This structure allows for an overlap area between the staggered upper heat exchange fin 4 and the lower heat exchange fin 6, ensuring normal fluid flow while improving turbulence. The upper and lower ends of the side of the rotary fluid tank 5 are respectively sealed with second fluid inlet and outlet pipe fittings 501, and a partition 502 is also sealed and snapped into the inside of the rotary fluid tank 5. Furthermore, the rotary fluid tank 5 and the second fluid tank 3 form an S-shaped flow channel through the partition 502. This structure allows fluid to enter the rotary fluid tank 5 through the second fluid inlet and outlet pipe fittings 501, and the S-shaped flow channel extends the fluid flow path, ensuring sufficient heat exchange treatment.

[0018] Working Principle: When using this multi-layer staggered finned heat exchanger, the heat exchanger body 1 operates by allowing two fluids to enter and exit the first fluid tank 2 and the rotary fluid tank 5 through the first fluid inlet / outlet connecting cover 201 and the second fluid inlet / outlet pipe fitting 501, respectively. The fluid in the first fluid tank 2 flows through the gap between the upper heat exchange fins 4 and the lower heat exchange fins 6, and undergoes efficient heat exchange during the flow. The rotary fluid tank 5 and the multi-layered second fluid tank 3 form an S-shaped channel under the action of the partition 502. The sealing plug 301 is sealed and snapped into the first fluid tank 2 and the rotary fluid tank 5 to ensure that the two fluids do not flow into each other. When the fluid flows in the second fluid tank 3, it undergoes heat exchange through the cooperation of the upper heat exchange fins 4 and the lower heat exchange fins 6. The staggered arrangement of the upper heat exchange fins 4 and the lower heat exchange fins 6 effectively improves the heat exchange efficiency and makes the overall structure more compact, thereby completing a series of tasks.

[0019] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
