Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a self-cleaning heat exchanger. Background Technology

[0002] A heat exchanger is a device used to transfer heat between fluids at different temperatures. It is crucial in many industrial and domestic applications. Here is some specific information about heat exchangers. The working principle of a heat exchanger is based on three basic modes of heat transfer: conduction, convection, and radiation. In an indirect heat exchanger, two fluids at different temperatures exchange heat through a solid wall without direct contact. This design prevents the two fluids from mixing while allowing heat to be transferred from the higher-temperature fluid to the lower-temperature fluid. A mixing heat exchanger, on the other hand, transfers heat by allowing the two fluids to come into direct contact. This method is typically used in applications requiring rapid and high-volume heat exchange. Indirect heat exchangers include shell-and-tube and plate types. Shell-and-tube heat exchangers consist of a shell, tube bundle, tube sheet, and end caps, where one fluid flows inside the tubes and the other flows outside, exchanging heat through the tube walls. Regenerative heat exchangers transfer heat from a higher-temperature fluid to a lower-temperature fluid through a regenerative medium, commonly found in certain industrial processes. Mixing heat exchangers exchange heat through direct contact between the two fluids, such as cooling towers and gas scrubbing towers.

[0003] During use, a large amount of scale will remain in the hot water pipes of the heat exchanger, which will affect the heat exchange efficiency of the heat exchanger. At the same time, the side of the cold water flowing in the cold water pipe that is away from the hot water pipe absorbs less heat than the side of the cold water that is closer to the hot water pipe. As a result, the heat in the hot water pipe cannot be fully absorbed, and the heat of the hot water in the pipe is lost to the outside, thus affecting the heat exchanger. To address this, we propose a self-cleaning heat exchanger. Utility Model Content

[0004] The purpose of this invention is to provide a self-cleaning heat exchanger to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning heat exchanger, comprising an exchange chamber:

[0006] The lower ends of both sides of the exchange chamber are provided with mounting plates, and the lower ends of the two sets of mounting plates are provided with base plates. The upper end of the exchange chamber is provided with a water inlet, and the lower surface of the exchange chamber is provided with a water outlet. The left side of the exchange chamber is provided with a fixing plate, and two sets of exchange pipes are inserted between the exchange chamber and the fixing plate. The interior of the exchange chamber is provided with a cleaning pipe.

[0007] Preferably, support seats are provided at the four corners of the lower surface of the base plate, and rubber anti-slip blocks are provided at the lower ends of the four sets of support seats. The rubber anti-slip blocks can increase the friction between the heat exchanger and the ground, effectively reduce the shaking of the equipment caused by vibration, and thus maintain the stable operation of the equipment.

[0008] Preferably, the front surface of the exchange chamber has a slot, and an observation window is provided in the slot to facilitate observation of the situation inside the exchange chamber.

[0009] Preferably, a piston is inserted between the inlet and outlet to facilitate the addition or removal of cleaning fluid into the exchange chamber.

[0010] Preferably, the fixing plate is provided with fixing frames on both the front and rear sides, and the two sets of fixing frames are connected to the left side of the exchange compartment on opposite sides, which can facilitate the passage of the drive motor.

[0011] Preferably, the cleaning tube is provided with a gear at its left end, and a matching tooth groove is provided on the left side of the exchange chamber, which allows the cleaning tube to rotate to clean the exchange chamber.

[0012] Preferably, a drive motor is installed on the left side of the gear, and a rotating plate is rotatably installed on the left side of the exchange compartment and the fixed plate. The drive motor is fixedly installed on the left side of the rotating plate, which allows the gear to rotate on the left side of the exchange compartment via the rotating plate when the drive motor drives the gear to rotate.

[0013] This utility model has at least the following beneficial effects:

[0014] The system is equipped with an inlet and an outlet. By opening the piston at the inlet, cleaning fluid is added into the exchange chamber. After cleaning is completed, the wastewater is discharged by opening the piston at the outlet.

[0015] Equipped with a drive motor, turning on the motor causes the gears to rotate within the exchange chamber. The gears engage with the grooves within the exchange chamber, causing the cleaning tube to rotate around the center of the chamber and then in a circular motion. This rotation of the cleaning tube along the inner wall allows for wider coverage, ensuring that all parts of the chamber's interior are cleaned. The rotation further enhances the cleaning effect, allowing the bristles or cleaning tools on the cleaning tube to reach deeper into the dirt and residue, effectively removing them.
