Abstract
The utility model relates to an adopt heat exchange tube of wave fin, arrange in a plurality of fins of heat exchange tube periphery including heat exchange tube and the radial parallel along the heat exchange tube, a plurality of fins set two in the upper and lower bilateral central symmetry of heat exchange tube. The fin be the wave fin, the cross-section in the radial direction of heat exchange tube is the rectangle, the length of rectangle is 1.5 ~ 2.5 times of the external diameter of heat exchange tube, the width is 1 ~ 2 times of the external diameter of heat exchange tube, just the fin sets up to the semicircle groove with heat exchange tube external diameter complex with heat exchange tube contact position. The fins are made of steel plates or other hard metals and are fixed on the periphery of the heat exchange tube in a welding or cementing mode. The utility model discloses under the condition that does not change former indirect heating equipment's volume, effectively improved heat exchange efficiency, guarantee indirect heating equipment compact structure.
Description
Technical Field
The utility model relates to a heat exchange element that heat transfer equipment used especially discloses a heat exchange tube of adopting wave fin piece.
Background
Fins, also known as fins or fins, are commonly used in heat exchange equipment, and can increase heat transfer area, reduce thermal resistance for convective heat transfer, and enhance heat transfer capability of the equipment, such as condensers, radiators, air heaters, and the like, of refrigeration devices. In order to increase the heat exchange efficiency and reduce the volume of the heat exchanger, the heat exchange surface area is generally increased by adopting heat exchange tubes with fins, the conventional heat exchange tubes with fins are flat steel plates, and the common fins are trapezoidal fins, triangular fins and rectangular fins.
Under the condition that the size of the heat exchange equipment is not influenced, the heat exchange surface area maximization of the heat exchange tube with the flat plate type steel plate fins cannot be realized, when the heat exchange quantity needs to be increased, the number of the fins can only be correspondingly increased, the size of the heat exchange equipment is correspondingly increased, and the normal use of a user on the equipment is probably influenced.
Disclosure of Invention
The utility model aims at solving prior art's defect, design an adopt heat exchange tube of wave fin piece, design the fin into the wave, set up the fin that occupies the same space size on the heat exchange tube of same length respectively, the heat transfer surface area of wave fin piece obviously is greater than conventional flat fin, has improved heat exchange efficiency, and can not change heat exchange equipment's volume.
The utility model discloses a realize like this: the utility model provides an adopt heat exchange tube of wave fin, includes heat exchange tube and a plurality of fins of radial parallel arrangement in the heat exchange tube periphery along the heat exchange tube, its characterized in that: the fin be the wave fin, be a wave avris and regard as and link up by smooth mellow and smooth and a plurality of positive and negative corresponding circular arcs that the radian size equals and form, a plurality of fins set to two in heat exchange tube upper and lower bilateral central symmetry, set up to the semicircle groove with heat exchange tube external diameter complex with heat exchange tube contact position.
The section of the wavy fin in the radial direction of the heat exchange tube is rectangular, the length of the rectangular fin is 1.5-2.5 times of the outer diameter of the heat exchange tube, and the width of the rectangular fin is 1-2 times of the outer diameter of the heat exchange tube. The fins are made of steel and are fixed on the heat exchange tube in a welding or gluing mode, and the welding mode is optimized. The fins are correspondingly divided into 10-100 fins according to the size and the volume of the heat exchange equipment, and the fins are arranged on the heat exchange pipe in parallel.
The utility model has the advantages that: the utility model discloses with the fin of wave design, replace current flat fin on the heat exchange tube, set up the different shape fins of the same quantity respectively on the heat exchange tube of same length, the heat transfer surface area of wave fin is obviously greater than conventional flat fin, has effectively improved heat exchange efficiency, and all adopts smooth mellow and full wave line design, does benefit to heat transfer medium and flows, and whole occupation space size does not change simultaneously, can not change former indirect heating equipment's volume.

Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
According to attached drawing 1 and attached drawing 2, the utility model relates to an adopt heat exchange tube of wave fin, including heat exchange tube 1 and a plurality of fins 2 of radial parallel arrangement in heat exchange tube 1 periphery along heat exchange tube 1, a plurality of fins 2 set to two at heat exchange tube 1 upper and lower bilateral central symmetry. Fin 2 be the wave fin, be a wavy avris and regard as and link up by smooth mellow and smooth and a plurality of positive and negative corresponding circular arcs that the radian size equals and form, the wave fin is the rectangle at the cross-section of heat exchange tube 1's radial direction, and the length of rectangle is 1.5 ~ 2.5 times, preferred 2 times of the external diameter of heat exchange tube 1's pipe, and the width is 1 ~ 2 times of the external diameter of heat exchange tube 1, just fin 2 sets up to the semicircle groove with 1 external diameter complex of heat exchange tube with 1 contact site of heat exchange tube. The fins 2 are made of steel plates or other hard metals, are fixed on the periphery of the heat exchange tube 1 in a welding or cementing mode, and the welding mode is preferred.
The utility model discloses under the condition that does not change former indirect heating equipment's volume, effectively improved heat exchange efficiency, guarantee indirect heating equipment compact structure.
