[0013] The present invention provides an adjustable air heat exchanger. Compared with the prior art, it has the following beneficial effects: (1) Through the setting of the pipeline stepping movement mechanism, the automatic adjustment of the insertion amount of the intake pipe into the heat exchange finned tubes is realized. By changing the intake position in the heat exchange finned tubes, the heat exchange time using the heat exchange finned tubes is further changed, achieving the purpose of freely controlling the heat exchange efficiency. When the insertion amount of the intake pipe is larger, the path of the air passing through the heat exchange finned tubes is shorter, the heat exchange time is less, and the heat exchange efficiency is lower. When the insertion amount of the intake pipe is smaller, the path of the air passing through the heat exchange finned tubes is longer, the heat exchange time is more, and the heat exchange efficiency is higher. It can be adaptively adjusted according to the external environmental temperature, air flow rate or heat exchange requirements.

[0014] (2) Through the setting of the dust accumulation cleaning component, the cleaning of the dust accumulated on the inner wall of the heat exchange finned tubes is realized. In cooperation with the pipeline stepping movement mechanism, the cleaning is carried out during the period when the intake pipe stops after stepping movement, which can better and quickly clean the dust. After cleaning the dust, it can prevent the dust from blocking the pipeline and improve the intake effect and heat exchange efficiency.

[0015] (3) Through the setting of the intake angle adjustment component, when the dust accumulation cleaning component works, it can drive the swing plate to swing synchronously. By using the continuous reciprocating swing of the swing plate, the intake angle is continuously changed, the contact position between the air and the inner wall of the heat exchange finned tubes is flexibly changed, the contact area between the air and the tube wall is increased, the original flow direction of the air is disrupted, and the air is more evenly distributed on the heat exchange core body, avoiding excessive or insufficient local heat exchange and further improving the heat exchange efficiency.

[0016] (4) Through the setting of the knocking vibration component, when the pipeline stepping movement mechanism works, it can drive the knocking vibration component to work synchronously, so that the ball reciprocally knocks the heat exchange finned tubes. The knocking vibration can periodically break the fluid boundary layer on the inner wall of the heat exchange finned tubes, increase the fluid turbulence degree, and improve the heat exchange efficiency. At the same time, the dust accumulated on the inner wall of the heat exchange finned tubes can also be shaken off through the knocking, further improving the heat exchange effect.

[0021] Through the setting of the pipeline step - by - step moving mechanism 6, the automatic adjustment of the insertion amount of the intake pipe 5 in the heat - exchange finned tube 3 is realized.

[0024] The toothed ring 155 is engaged with the third gear 154. A pipe sleeve 156 is fixed to one side of the toothed ring 155. The pipe sleeve 156 rotates sleeved on the air inlet pipe 5. A plurality of vertical rods 157 are fixed to the bottom of the pipe sleeve 156. A cleaning arc plate 158 is fixed to the bottom end of the vertical rod 157. The cleaning arc plate 158 is adapted to the size of the inner wall of the heat exchange fin tube 3. When the cleaning arc plate 158 rotates, it can clean the dust on the inner wall.

[0025] Through the setting of the dust accumulation cleaning assembly 15, the cleaning of the dust accumulated on the inner wall of the heat exchange fin tube 3 is realized. In cooperation with the pipeline step moving mechanism 6, the cleaning is carried out during the period when the air inlet pipe 5 stops after step moving, which can better and quickly clean the dust. After cleaning the dust, it can prevent the dust from blocking the pipeline and improve the air intake effect and heat exchange efficiency.

[0026] An air intake angle adjusting assembly 16 for adjusting the air intake angle is provided inside the air inlet pipe 5. The air intake angle adjusting assembly 16 includes a fixing rod 161 fixed between the inner walls of the air inlet pipe 5. Two rotating plates 162 are rotatably connected to the fixing rod 161. A swing plate 163 is fixed between one sides of the two rotating plates 162. The setting of the swing plate 163 can flexibly adjust the air intake angle, continuously change the contact position between the air and the inner wall of the pipe, disrupt the original flow direction of the air, and improve the heat exchange efficiency. An installation rod 164 is fixed between the opposite sides of the two rotating plates 162. A sliding seat 165 is slidably connected to the installation rod 164. A cross bar 166 is fixed to one side of the sliding seat 165. A rod sleeve 167 is fixed to the top wall of the air inlet pipe 5. A driving rod 168 is rotatably connected inside the rod sleeve 167.

[0027] One end of the driving rod 168 is fixed with a turntable 169. One end of the cross bar 166 penetrates through the turntable 169 and extends to the outside of the turntable 169. The outer surface of the cross bar 166 is slidably connected with the inner surface of the turntable 169. One end of the driving rod 168 is fixed with a first bevel gear 1610.

[0028] Through the arrangement of the air inlet angle adjusting assembly 16, when the dust collecting and cleaning assembly 15 works, the swing plate 163 can be synchronously driven to swing. By the continuous reciprocating swing of the swing plate 163, the air inlet angle is continuously changed, the contact position between the air and the pipe wall of the heat exchange fin tube 3 is flexibly changed, the contact area between the air and the pipe wall is increased, the original air flow direction is disrupted, the air is more evenly distributed on the heat exchange core, local overheating or insufficient heat exchange is avoided, and the heat exchange efficiency is further improved.

[0029] Embodiment 3: On the basis of Embodiment 2, see Figures 7-8 As shown in the figure, a knocking and vibrating assembly 7 is arranged on one side of the housing 1. The knocking and vibrating assembly 7 is used for intermittently knocking the heat exchange fin tube 3 to make the heat exchange fin tube 3 vibrate. The knocking and vibrating assembly 7 includes a folding plate 71 fixed on one side of the housing 1. A side plate 72 is fixed on one side of the folding plate 71. A side rod 73 is rotatably connected to one side of the side plate 72. A fifth bevel gear 74 is fixed to one end of the side rod 73.

[0030] A linkage rod 75 is rotatably connected inside the folding plate 71. A sixth bevel gear 76 is fixed to one end of the linkage rod 75. The fifth bevel gear 74 meshes with the sixth bevel gear 76. A ratchet wheel 77 is fixed to the other end of the linkage rod 75. A claw 79 is rotatably connected to one side of the folding plate 71 through a rotating column 78. A torsion spring is installed between the inside of the rotating column 78 and the folding plate 71. The setting of the torsion spring allows the claw 79 to quickly reset after swinging. The claw 79 is clamped with the teeth of the ratchet wheel 77. A cylinder 710 is fixed on the rotating column 78. A knocking rod 711 is fixed to the top of the cylinder 710. A spherical ball 712 is fixed to the top end of the knocking rod 711. When the spherical ball 712 swings, it can continuously knock the air outlet 17 end of the heat exchange fin tube 3 to generate vibration.

[0031] Through the arrangement of the knocking and vibrating assembly 7, when the pipeline stepping moving mechanism 6 works, the knocking and vibrating assembly 7 can be synchronously driven to work, so that the spherical ball 712 reciprocally knocks the heat exchange fin tube 3. The knocking vibration can periodically break the fluid boundary layer on the inner wall of the heat exchange fin tube 3, increase the fluid turbulence degree, improve the heat exchange efficiency, and at the same time, the dust accumulated on the inner wall of the heat exchange fin tube 3 can also be shaken off through knocking, further improving the heat exchange effect.

[0032] A pulley 8 is fixed on each of the side rod 73 and one of the connecting rods 67. The two pulleys 8 are drivingly connected by a belt 9. Through the arrangement of the pulleys 8 and the belt 9, the pipeline stepping movement mechanism and the knocking vibration assembly can work synchronously.

[0033] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0034] During operation, insert the intake pipe 5 into the heat exchange fin tube 3 and tighten the limit ring 10. When it is necessary to improve the heat exchange efficiency, start the first motor 66. The first motor 66 drives the first gear 64 and the second gear 65 to rotate in opposite directions. Further, the first gear 64 and the second gear 65 drive the two runners 68 to rotate synchronously in opposite directions. When the runner 68 drives the arc-shaped convex block 69 to rotate into the clamping groove 62, it drives the support plate 61 and the intake pipe 5 to extend into the heat exchange fin tube 3. By changing the air intake position of the intake pipe 5 in the heat exchange fin tube 3, the heat exchange time is shortened, thereby reducing the heat exchange efficiency. By reversing the first motor 66, the intake pipe 5 can be extended to the right, and the time for the air to contact the heat exchange fin tube 3 is extended, so as to improve the heat exchange efficiency. Start the second motor 153 to make the second motor 153 rotate forward and backward. The second motor 153 drives the rotating rod 152 to rotate. The rotating rod 152 drives the third gear 154 to rotate. The third gear 154 drives the toothed ring 155 to rotate. The toothed ring 155 drives the cleaning arc plate 158 to rotate forward and backward. When the cleaning arc plate 158 rotates, it sweeps the dust accumulated on the inner wall of the heat exchange fin tube 3, and finally discharges it from the air outlet 17 through the air flow. When the cleaning arc plate 158 rotates to be about to contact the rotating rod 152, the cleaning arc plate 158 reverses. Utilizing the time when the pipeline stepping movement mechanism 6 stays during operation, the cleaning arc plate 158 performs dust cleaning during this time period. The heat exchange fin tube 3 after dust cleaning can expand the contact area with the air and improve the heat exchange efficiency. When the rotating rod 152 rotates, it synchronously drives the movable rod 1611 to rotate. The movable rod 1611 drives the turntable 169 to rotate. Further, the turntable 169 drives the rotating plate 162 and the swing plate 163 to swing around the fixed rod 161. By using the swing of the swing plate 163, the blowing angle of the air is continuously adjusted, increasing the contact area between the air and the tube wall of the heat exchange fin tube, and improving the heat exchange efficiency. When the runner 68 rotates, through the cooperation of the pulley 8 and the belt 9, it synchronously drives the side rod 73 to rotate. Further, the side rod 73 drives the ratchet wheel 77 to rotate. When the ratchet wheel 77 rotates, it drives the pawl 79 to perform reciprocating swinging around the rotating column 78, and further drives the ball 712 to continuously knock the heat exchange fin tube 3. The vibration of the heat exchange fin tube 3 causes the fluid boundary layer on its inner wall to periodically break, increasing the fluid turbulence degree and improving the heat exchange efficiency. At the same time, the dust accumulated on the inner wall of the heat exchange fin tube 3 can also be shaken off through the knocking, further improving the heat exchange effect.

[0035] The embodiments of the invention have been described in detail above, but the above content is only the preferred embodiments of the present invention and should not be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
