Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a heat exchanger with a high-efficiency circulation function. Background Art

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. It is also called a heat exchanger. Its working principle is to achieve heat transfer between two or more fluids at different temperatures. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial production.

[0003] The patent application CN221349791U discloses a high-efficiency U-tube volumetric heat exchanger, comprising a cylinder, a heat exchange mechanism disposed inside the cylinder, an auxiliary component disposed outside the cylinder, the heat exchange mechanism comprising a U-shaped heat exchange tube fixedly connected to the cylinder, a heat sink fixedly connected to the outside of the U-shaped heat exchange tube, a regulating valve disposed inside the U-shaped heat exchange tube, and a water inlet pipe and a drain pipe fixedly connected to the left and right sides of the cylinder, respectively. This high-efficiency U-tube volumetric heat exchanger, by providing a heat exchange mechanism, improves the heat exchange effect and efficiency of the U-tube volumetric heat exchanger, increases the recovery of waste heat, saves resources, and solves the problem that heat exchange through a single U-tube is slow, which affects the heat exchange effect and efficiency of the U-tube volumetric heat exchanger, and does not have the function of recycling the steam generated by heat exchange, which easily leads to waste of resources.

[0004] Although the above scheme improves the heat exchange efficiency and can recycle the steam generated by heat exchange, thereby improving resource utilization, the different temperatures between the upper and lower layers of water lead to inconsistent heat exchange efficiency at different heights, and the heat exchange cycle efficiency is low. Therefore, we propose a heat exchanger with high-efficiency circulation function. Utility Model Content

[0005] The main purpose of this utility model is to provide a heat exchanger with efficient circulation function. By setting a main unit and a stirring unit, it solves the problem of inconsistent heat exchange efficiency at different heights and low heat exchange circulation efficiency due to the different temperatures between the upper and lower layers of water.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A heat exchanger with high-efficiency circulation function comprises a main unit, a stirring unit arranged in the main unit, and a water channel unit arranged on the main unit;

[0008] The main unit includes a heat exchange tube, a base installed at the bottom of the heat exchange tube, and a heat exchange element arranged inside the heat exchange tube;

[0009] The stirring unit includes a rotating cylinder movably arranged in the heat exchange cylinder, a first drive motor installed at the input end of the rotating cylinder, a second drive motor installed on the top wall of the rotating cylinder, a rotating shaft installed at the output end of the second drive motor, a driving gear installed on the side wall of the rotating shaft, and a stirring member arranged on the side of the rotating cylinder.

[0010] Preferably, the heat exchange element includes a heat exchange tube installed in the heat exchange cylinder, an air inlet pipe installed at the input end of the heat exchange tube, and an exhaust pipe installed at the output end of the heat exchange tube.

[0011] Preferably, the water channel unit includes a water inlet pipe opened at the top of the heat exchange cylinder, and a drain pipe opened at the side of the heat exchange cylinder.

[0012] Preferably, the water channel unit further includes a regulating valve movably arranged in the drain pipe.

[0013] Preferably, the stirring member includes a rotating through hole opened in the side wall of the heat exchange cylinder, a rotating rod movably arranged in the rotating through hole, a stirring rod installed on the side wall of the rotating rod, and a driven gear installed on the side wall of the rotating rod and meshing with the driving gear.

[0014] Preferably, there are multiple stirring members, and the multiple stirring members are symmetrically arranged with respect to a plane bisecting the rotation axis.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present utility model, through the main unit and the stirring unit, when it is necessary to ensure consistent heat exchange efficiency, the first drive motor drives the rotating drum to rotate, and the rotating drum drives the stirring element to rotate horizontally in a circle, so that the water and the heat exchange tube can be fully in contact. At the same time, the second drive motor drives the rotating shaft to rotate, and the rotating shaft drives the driving gear to engage the driven gear, so that the rotating rod drives the stirring rod to fully mix the water between the upper and lower layers, avoiding the different temperatures of water at different heights due to stratification, ensuring consistent water temperature, and improving the circulation heat exchange efficiency; when heat exchange is required, water is added from the water inlet pipe, and the heat medium enters the heat exchange tube from the air inlet pipe. At the same time, the stirring unit works to make the water fully in contact with the heat exchange tube. When the heat exchange is completed, the heat medium is discharged from the exhaust pipe, and the regulating valve can be opened to allow the water to be discharged from the drain pipe.
