Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to an adjustable and efficient heat exchanger. Background Art

[0002] A heat exchanger is an energy-saving device that realizes heat transfer between two or more fluids at different temperatures. It enables heat to be transferred from a fluid with a higher temperature to a fluid with a lower temperature, so that the fluid temperature reaches the specified index of the process to meet the needs of process conditions. At the same time, it is also one of the main devices for improving energy utilization efficiency and has a wide range of applications. As the working time increases, water scale adheres to the heat exchange cylinder, resulting in a decline in the heat exchange effect. At the same time, due to different geographical locations and environments, the heat exchange efficiency is different, making it difficult to control and adjust. Moreover, it cannot change the water flow rate following the change of the hot air flow rate. There is no protection device, resulting in overheating of the heat exchange cylinder, and the service life of the heat exchange cylinder is likely to be shortened during long-term operation. Content of the Utility Model

[0003] The purpose of the utility model is to provide an adjustable and efficient heat exchanger to overcome the above-mentioned defects in the prior art.

[0004] According to an adjustable and efficient heat exchanger of the utility model, it includes a first fixing plate. A working cylinder is arranged at the upper end of the first fixing plate. The working cylinder and the first fixing plate are connected by a support mechanism. The support mechanism includes a support frame fixed on the first fixing plate, a fixing ring fixed on the working cylinder, and the fixing ring and the support frame are connected by a connecting rod. Removable left and right heat exchange cylinders are respectively fixed at the left and right ends of the working cylinder. Handles are fixed at the mutually remote ends of the left and right heat exchange cylinders. The left and right heat exchange cylinders are in contact with each other and sealed by a sealing ring. A heat exchange cavity is communicated and opened between the left and right heat exchange cylinders. A threaded guide rail is rotatably fitted in the first fixing plate and is located at the outer ends of the left and right heat exchange cylinders. Inlet and outlet water pipes are respectively and communicatively fixed at the left and right ends of the first fixing plate. A pneumatic mechanism is connected to the left end of the first fixing plate. An air inlet pipe is communicated with the pneumatic mechanism. A rotating mechanism is arranged in the pneumatic mechanism. The right end of the rotating mechanism is connected with a rotating wheel. A gear ring is rotatably arranged at the left end of the first fixing plate. The rotating wheel meshes with the gear ring. The gear ring is fixedly connected with the threaded guide rail. A detachable air inlet pipe is communicatively fixed between the pneumatic mechanism and the heat exchange cavity. The air inlet pipe and the pneumatic mechanism are flange-connected. Two symmetrically arranged electromagnetic lifting rods are connected to the upper end of the first fixing plate. Two symmetrically arranged second fixing plates are fixed at the lower end of the first fixing plate. The two second fixing plates and the two electromagnetic lifting rods are hinged.

[0005] The beneficial effects of the present utility model are as follows:

[0006] By controlling the rotation speed of the threaded guide rail through the hot air flow rate, when the hot air flow rate increases, the total heat per unit time at the heat exchange chamber increases, and the rotation speed of the threaded guide rail is controlled to increase, so as to be able to divert the hot water absorption on the threaded guide rail faster, increase the heat exchange efficiency, ensure that the temperature at the heat exchange chamber is at a suitable temperature for the operation of the left heat exchange cylinder and the right heat exchange cylinder, prevent the phenomenon that the temperature at the heat exchange chamber gradually rises, and maintain the heat exchange work. On the contrary, the water flow speed at the threaded guide rail decreases, ensuring that the water flow fully exchanges heat with the heat at the heat exchange chamber. The inclination angle of the working cylinder is adjusted by the electromagnetic lifting rod to adjust the water flow speed in different environments, which is more in line with the actual requirements. The heat exchange chambers are distributed in layers, increasing the flow time of the hot air in the heat exchange chamber. BRIEF DESCRIPTION OF THE DRAWINGS

Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0016] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time.

[0017] Embodiment 1:

[0018] Referring to Figures 1-6 , an adjustable and efficient heat exchanger according to an embodiment of the present utility model includes a first fixing plate 10. A working cylinder 11 is provided at the upper end of the first fixing plate 10. The working cylinder 11 is connected to the first fixing plate 10 through a support mechanism 12. The support mechanism 12 includes a support frame fixed on the first fixing plate 10, a fixing ring fixed on the working cylinder 11, and the fixing ring and the support frame are connected by a connecting rod. Removable left heat exchange cylinders 15 and right heat exchange cylinders 16 are respectively fixed at the left and right ends of the working cylinder 11. Handles are fixed at the mutually remote ends of the left heat exchange cylinder 15 and the right heat exchange cylinder 16. The left heat exchange cylinder 15 and the right heat exchange cylinder 16 are in abutment with each other and sealed by a sealing ring. A heat exchange cavity 17 is communicated and opened between the left heat exchange cylinder 15 and the right heat exchange cylinder 16. A threaded guide rail 18 is rotatably fitted in the first fixing plate 10. The threaded guide rail 18 is located at the outer ends of the left heat exchange cylinder 15 and the right heat exchange cylinder 16. Water inlet and outlet pipes 14 are communicated and fixed at the left and right ends of the first fixing plate 10. A pneumatic mechanism 19 is connected to the left end of the first fixing plate 10. An air inlet pipe is communicated on the pneumatic mechanism 19. A rotating mechanism is provided in the pneumatic mechanism 19. The right end of the rotating mechanism is connected to a rotating wheel 20. A gear ring 21 is rotatably provided at the left end of the first fixing plate 10. The rotating wheel 20 is engaged with the gear ring 21. The gear ring 21 is fixedly connected to the threaded guide rail 18. A detachable air inlet pipe 25 is communicated and fixed between the pneumatic mechanism 19 and the heat exchange cavity 17. The air inlet pipe 25 is flange-connected to the pneumatic mechanism 19. Two symmetrically arranged electromagnetic lifting rods 24 are connected to the upper end of the first fixing plate 10. Two symmetrically arranged second fixing plates 23 are fixed at the lower end of the first fixing plate 10. The two second fixing plates 23 and the two electromagnetic lifting rods 24 are hinged.

[0019] The hot air passes through the filter and then enters the pneumatic mechanism 19, pushing the rotating mechanism inside the pneumatic mechanism 19 to rotate, thereby driving the rotation of the rotating wheel 20 rotatably arranged on the pneumatic mechanism 19. Through the meshing between the rotating wheel 20 and the gear ring 21, the gear ring 21 is driven to rotate, and further the threaded guide rail 18 fixedly connected to the gear ring 21 rotates. The working cylinder 11 can be in an inclined state through the connection at the support mechanism 12. Through the rotation of the threaded guide rail 18, the water flow moves along the thread direction of the threaded guide rail 18, contacts the outer peripheral surface of the right heat exchange cylinder 16, and absorbs the heat at the heat exchange cavity 17. The rotation speed of the threaded guide rail 18 is related to the hot air flow rate entering the pneumatic mechanism 19. The greater the hot air flow rate, the faster the rotation speed of the threaded guide rail 18; conversely, the smaller the flow rate, the slower the rotation speed.

[0020] With the connection at the air inlet pipe 25, the hot air enters the heat exchange cavity 17 and is located in the outer part of the heat exchange cavity 17. Through the abutment between the left heat exchange cylinder 15 and the right heat exchange cylinder 16, the hot air flows in the heat exchange cavity 17 and gradually flows from the outer part of the heat exchange cavity 17 to different parts inside the heat exchange cavity 17, and through the connection of the air outlet pipe 13, it flows towards the air outlet pipe 13.

[0021] By energizing and working the electromagnetic lifting rods 24, the left and right electromagnetic lifting rods 24 respectively extend and retract up and down. Under the connection of the support mechanism 12, while keeping the center of the working cylinder 11 unchanged, the working cylinder 11 is inclined. Through the work of the electromagnetic lifting rods 24, under the hinge connection between the second fixing plate 23 and the electromagnetic lifting rods 24, the overall inclination angle of the working cylinder 11 fixedly connected to the second fixing plate 23 is adjusted.

[0022] Those skilled in the art can clearly understand that various modifications can be made to the above embodiments without departing from the general spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scope of the present invention is subject to the claims attached to the present invention.
