[0002] A semi-volumetric heat exchanger is a heat exchange device that enhances heat exchange by increasing the flow rate of the heat medium inside the tubes and the heated water outside the tubes, thereby significantly improving the heat transfer coefficient.

[0003] In the prior art, such as the "semi-volume heat exchanger" in Chinese Patent No. CN202220800389.8, there are water tanks, heat exchange mechanisms, flow guiding and stirring mechanisms, water inlets, water outlets, pressure relief safety valves, drain outlets, brackets and thermometers. The heat exchange mechanisms are fixedly connected to the outer wall of the water tanks, and the flow guiding and stirring mechanisms are fixedly connected to the upper surface of the water tanks. The flow guiding and stirring mechanisms include guide plates and motors.

[0004] However, after prolonged use, existing heat exchange tube bundles are prone to scaling on their surface, and once scaling occurs, it is difficult to remove the tube bundles for thorough cleaning, which leads to a gradual decrease in heat exchange efficiency and affects the performance and lifespan of the equipment. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the surface of the heat exchange tube bundle is prone to scaling after long-term use, and it is difficult to remove the tube bundle for thorough cleaning after scaling, which leads to a gradual decrease in heat exchange efficiency and affects the performance and service life of the equipment. Therefore, a semi-volumetric heat exchanger is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a semi-volumetric heat exchanger, comprising a housing structure, an internal stirring mechanism, and a heat exchanger mechanism. The housing structure includes a water tank shell, with a connection port fixedly connected to one end of the water tank shell. The heat exchanger mechanism includes a connector, a sealing plug on the side of the connector, an inlet pipe extending through the side of the sealing plug, a heat exchange tube fixedly connected to one end of the inlet pipe, an outlet pipe fixedly connected to one end of the heat exchange tube, the outlet pipe extending through the side of the connector, symmetrically mounted sliding seats at the bottom of the connector, a three-stage telescopic rail slidably connected to the outer side of the sliding seats, a two-stage telescopic rail slidably connected to the outer side of the three-stage telescopic rail, and a one-stage telescopic rail slidably connected to the outer side of the two-stage telescopic rail. The connector is connected to one end of the connection port.

[0007] Preferably, the stirring mechanism includes an electric motor, the output end of which is connected to a drive shaft, and a plurality of horizontal stirring blades are evenly distributed on the outer wall of the drive shaft, which passes through one end of the water tank shell.

[0008] Preferably, a connecting sleeve is provided on the side of the connector, the connecting sleeve is fitted onto one end of the connection port, a plurality of sealing rings are distributed on the outer side of the sealing plug, the sealing rings are connected to the inner wall of the connection port, and an mounting plate is fixedly connected to one end of the primary telescopic rail, the mounting plate is installed on the end of the water tank shell.

[0009] Preferably, a water inlet is fixedly connected to one end of the top of the water tank shell, and a pressure relief valve is fixedly connected to the other end of the top of the water tank shell.

[0010] Preferably, a drain outlet is fixedly connected to one end of the water tank shell, and a sewage outlet is fixedly connected to the bottom of the water tank shell.

[0011] Preferably, a support frame is symmetrically installed at the bottom of the water tank shell, and fasteners are symmetrically arranged at the top of the water tank shell, with both ends of the fasteners fixedly connected to the top of the support frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, a mounting plate is used to connect and install the primary telescopic rail, maintaining stable support. A secondary telescopic rail is slidably connected to the inner side of the primary telescopic rail, and a tertiary telescopic rail is slidably connected to the inner side of the secondary telescopic rail. A sliding seat is slidably installed on the inner side of the tertiary telescopic rail. The sliding seats are symmetrically connected to the bottom of the connector, thus providing stable support. This facilitates the removal of scale from the outer wall of the heat exchange tube when cleaning is required. By disassembling the connector and the connection port, the connector and part of the heat exchange tube can be easily pulled out to the outside. During the extraction process, the sliding seat slides on the tertiary telescopic rail, then slides on the secondary telescopic rail, and then slides on the primary telescopic rail, so that the heat exchange tube is completely exposed to the outside. This facilitates comprehensive cleaning of the heat exchange tube, ensuring effective removal of scale and guaranteeing the heat exchange effect in the later stages.

In this utility model, the electric motor is located at the outer end of the water tank shell, and the output end is connected to the drive shaft, which realizes the driving transmission function. Several horizontal stirring blades are evenly distributed on the outer wall of the drive shaft, which facilitates the real-time monitoring of the water temperature inside the water tank shell by the temperature sensor at the top during the heat exchange process. When the temperature rises, the horizontal stirring blades are used to stir the water, which mixes the water and helps to improve the heat exchange effect. Furthermore, the use of horizontal large-range detection helps to further improve the heat exchange effect. Attached Figure Description
