Description

TECHNICAL FIELD

[0001] The utility model relates to heat exchange equipment technical field, especially relate to a heat exchange device. BACKGROUND

[0002] At present, the evaporative condenser widely adopts the coil type heat exchange pipe as the main heat exchange element. In this kind of design, the heat exchange capacity of the heat exchange pipe directly determines the working efficiency of the whole condenser. However, the heat dissipation mode relying on the heat exchange pipe itself inevitably limits the effective heat dissipation area of the condenser, resulting in low overall heat dissipation efficiency. In addition, in the traditional design scheme, the heat exchange coil is directly in contact with cooling water, which not only easily causes the surface of the heat exchange coil to rust and corrode, but also significantly shortens the service life of the heat exchange pipe. At present, the market more adopts the mode of coating the heat dissipation fin on the heat exchange pipe to increase the heat dissipation area. Although this improvement improves the heat exchange efficiency to a certain extent, due to the limitation of structure, the inner wall of the heat dissipation fin coated outside the heat exchange pipe cannot fully contact with the external environment to participate in the heat exchange process. This results in dry spots and dead angles on the surface of the heat dissipation fin, which cannot fully utilize the heat dissipation area, thereby greatly reducing the evaporation heat transfer efficiency. SUMMARY

[0006] Heat dissipation component, including laminated first heat dissipation fin and second heat dissipation fin, first heat dissipation fin is provided with first slot, second heat dissipation fin is provided with second slot, and the projection part of first slot and second slot in depth direction is partially overlapped or completely staggered.

[0007] According to the heat exchange device, the following beneficial effects are achieved: the heat exchange pipe row is composed of multiple straight pipes and elbows connecting the straight pipes, and forms a continuous flow channel, which not only simplifies the fluid path inside the condenser and reduces pressure loss, but also effectively increases the contact time and area between the fluid and the pipe wall, thereby improving the heat exchange efficiency; the heat dissipation assembly includes the first heat dissipation fin and the second heat dissipation fin which are stacked and are respectively provided with the first slot and the second slot, the design of the slots makes it possible to partially overlap or completely stagger the projection layout, and ensures that the heat dissipation fins can fully utilize their surface area for heat exchange, avoiding the dry point and dead angle problems in the traditional design, and the overlapping part of the two heat dissipation fins after being attached can participate in heat exchange, so that all the area of the heat dissipation fins can participate in heat exchange, thereby improving the heat exchange efficiency of the heat exchange pipe row; the reasonably arranged slots and heat dissipation fins help to uniformly distribute the heat load, reduce local overheating phenomenon, and thereby protect the material from excessive wear and corrosion, prolonging the service life of the equipment.

[0030] The heat exchange tube row is composed of multiple straight tubes 105 and elbows 100 connecting the straight tubes 105, forming a continuous flow channel. This design not only simplifies the fluid path inside the condenser, reduces pressure loss, but also effectively increases the contact time and area between the fluid and the tube wall, thereby improving the heat exchange efficiency; the heat dissipation assembly includes stacked first and second heat dissipation fins 110 and 120, which are respectively provided with first and second slots 145 and 150. The design of these slots makes it possible to have partially overlapping or completely staggered projection layouts, and ensures that the heat dissipation fins can fully utilize their surface area for heat exchange, avoiding the dry spots and dead angles in traditional designs. The overlapping parts of the two heat dissipation fins can participate in heat exchange after being attached, so that all the area of the heat dissipation fins can participate in heat exchange, thereby improving the heat exchange efficiency of the heat exchange tube row. The reasonable layout of the slots and heat dissipation fins helps to evenly distribute the heat load, reduce local overheating, and thus protect the material from excessive wear and corrosion, prolonging the service life of the equipment.

[0031] The first heat dissipation fin 110 is provided with multiple first slots 145 at equal intervals, and the first heat dissipation part 160 formed between adjacent two first slots 145 has a width of 1.1-1.2 times the width of the second slot 150; the second heat dissipation fin 120 is provided with multiple second slots 150 at equal intervals, and the second heat dissipation part 170 formed between adjacent two second slots 150 has a width of 1.1-1.2 times the width of the first slot 145. The second heat dissipation part 170 is arranged corresponding to the first slot 145, and the first heat dissipation part 160 is arranged corresponding to the second slot 150, so that each heat dissipation part can realize back heat exchange through the corresponding slot.

In some preferred embodiments, the slot length of the first slot 145 and the second slot 150 is 20mm, and the slot width is 2mm, which can help to evenly distribute the heat load and reduce local overheating.

[0034] The first heat exchange fin 130 is arranged in a direction away from the first heat dissipation fin 110, and the second heat exchange fin 140 is arranged in a direction away from the second heat dissipation fin 120. The inclined heat exchange fin can guide the airflow to be more evenly distributed on the surface of the heat dissipation fin, avoiding the problem of uneven heat exchange caused by too fast or too slow airflow in local areas. Such design ensures the effective use of the entire heat exchange surface and improves the overall heat exchange efficiency.

[0035] The angle between the first heat exchange fin 130 and the first length direction slot 145 is 45°-90°, and the angle between the second heat exchange fin 140 and the second length direction slot 150 is 45°-90°. Smaller angles can increase the airflow path length and disturbance, improving heat exchange efficiency; while larger angles can help simplify the structure and maximize the use of space.

[0036] The first heat exchange fin 130 and the second heat exchange fin 140 are provided with a hydrophobic coating on the surface. The hydrophobic coating makes the fin surface not easy to be contaminated by dust, oil stains and other impurities, which helps to maintain long-term efficient operation. Even if a small amount of dust adheres, it is easy to be carried away by flowing air, reducing the need for cleaning and maintenance.

[0037] The first heat exchange fin 130 and the second heat exchange fin 140 are formed by stamping. It can produce a large number of heat exchange fins with consistent shape and high precision in a short time, which is suitable for mass production, helps to reduce unit cost and improve production efficiency.

[0040] This embodiment details a high-efficiency condenser design based on the aforementioned technical features, aiming to improve overall heat exchange efficiency by optimizing the configuration of heat exchange tube arrays and heat dissipation components. The specific design details and steps are as follows.

[0041] A continuous flow channel is formed by connecting multiple straight pipes 105 end to end with elbows 100. The length of each straight pipe 105 is customized according to actual needs to maximize the heat exchange area within a limited space. Copper or aluminum alloy with good thermal conductivity and corrosion resistance is selected as the material for the straight pipes 105 to extend service life and improve heat transfer efficiency.

The projected portions of the first slots 145 and the second slots 150 in the depth direction overlap or are completely offset to optimize the airflow path.

[0043] A first heat exchange fin 130 is provided on one side of the first slot 145, and a second heat exchange fin 140 is provided on one side of the second slot 150. The heat exchange fins are installed at an angle of 45° to 90°, away from the corresponding heat sink surface, to enhance airflow turbulence and promote heat transfer. A hydrophobic coating is applied to the surfaces of the first heat exchange fin 130 and the second heat exchange fin 140 to reduce moisture accumulation, prevent scaling, and improve condensation efficiency.

[0044] The first heat sink 110 and the second heat sink 120 are fixedly connected using laser welding, thermally conductive epoxy resin, or riveting. The most suitable connection method is selected based on the specific requirements of the application scenario. A thin and uniform layer of thermally conductive silicone grease is filled at the connection interface to ensure tight contact, reduce contact thermal resistance, and improve heat conduction efficiency.

[0045] The first heat exchange fin 130 and the second heat exchange fin 140 are manufactured using a stamping process to ensure dimensional accuracy and consistency, while optimizing material utilization and reducing waste. All components are precisely assembled according to the design drawings, ensuring correct alignment of all parts, and necessary quality inspections are performed, such as pressure testing and leak detection.

[0046] Thanks to its optimized slotted design, inclined heat exchange fins, and hydrophobic coating, this condenser delivers higher heat exchange capacity within the same volume. Its rational structural design and material selection strategy not only ensure a long service life but also allow it to adapt to various operating conditions. Its efficient self-cleaning capability and simple maintenance process make it easier for users to maintain the equipment in optimal operating condition.

[0047] To sum up, the embodiment shows a design scheme of a high-efficiency condenser, which realizes excellent heat exchange performance and good economy through innovative structural design and advanced manufacturing process, and is suitable for various application scenarios requiring efficient heat energy conversion.
