Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a heat exchanger for energy storage in coastal zero-carbon buildings. Background Art

[0002] A zero-carbon building refers to a building with zero carbon emissions that can operate independently of the power grid and can rely on solar or wind energy. This type of building does not consume coal, oil, electricity or other energy sources. All of its energy consumption throughout the year is provided by renewable energy generated on site, thereby thoroughly implementing the concept of environmental protection.

[0003] At present, the energy provided by renewable energy in zero-carbon buildings needs to be utilized through a variety of conversion equipment, such as heat exchangers, which are devices used to transfer heat from hot fluid to cold fluid to meet regulatory requirements. After use, they can meet practical life needs such as collective heating of households and hot water in winter. However, in reality, the liquid medium flowing inside the heat exchanger, such as water, may contain certain impurity particles. After long-term use, they will gradually accumulate on the inner wall of the heat exchange structure of the heat exchanger, thereby reducing the heat exchange effect of the heat exchanger and increasing the consumption of useless functional energy, which has an adverse impact on the overall smooth operation of the zero-carbon building.

In addition to ensuring the reliability of the structure during use, it also maintains the convenience of subsequent disassembly and maintenance.

[0007] The heat exchanger body is selected to have hot medium inlet arrow marks and cold medium inlet and outlet marks respectively provided on both side surfaces for convenient installation by subsequent operators, and the bottom of the heat exchanger body is fixedly connected to a support frame, and mounting holes are provided on both sides of the support frame to provide structural conditions for the stable installation of the entire device.

[0008] The valves inside the two filter valve tubes, the valves inside the two transition valve tubes, the valves inside the two return valve tubes, and the valves inside the two diverter valve tubes are all solenoid valves, which facilitates unified operation and regulation of the background control equipment.

[0009] The adjustable filter assembly includes a supporting frame and a brake stepper motor. Several first filter screens are nested inside the heat exchanger body. The output end of the brake stepper motor passes through the side wall of the corresponding filter valve tube and is transmission-connected to one side of the supporting frame. A shaft sealing ring is nested in the output end of the brake stepper motor and the corresponding filter valve tube fitting to avoid water leakage at the fitting of the brake stepper motor and the filter valve tube.

[0010] The surface of the support frame is carefully embedded with an auxiliary sealing ring that can fit and connect with the inner wall of the filter valve tube, thereby improving the connection sealing effect between the support frame and the filter valve tube. A support frame is installed between the shell surface of the brake stepper motor and the surface of the filter valve tube to ensure the stability of the brake stepper motor during use.

The mesh number of the second filter screen 11 is the same as the mesh number inside the first filter screen 93.

[0029] Working principle:

[0030] Example 1

[0031] The fluid medium entering the heat exchanger body 1 will be filtered synchronously, as follows:

[0032] When the hot fluid medium enters the interior of the heat exchanger body 1 through the transition valve pipe 6, the filter valve pipe 7 and the hot medium inlet pipe 2 at the front end of the hot medium inlet pipe 2, and then flows out through the hot medium outlet pipe 3, at the same time, the cold fluid medium enters the interior of the heat exchanger body 1 through the transition valve pipe 6, the filter valve pipe 7 and the cold medium inlet pipe 4 at the front end of the cold medium inlet pipe 4, and then is discharged through the cold medium outlet pipe 5;

[0033] When the hot fluid medium or the cold fluid medium passes through the corresponding filter valve tube 7, it will be filtered synchronously by the filter structure composed of the support frame 91 and multiple first filter screens 93 set inside the filter valve tube 7, and then enter the heat exchanger body 1 to perform hot and cold exchange operations.

[0034] Example 2

[0035] When cleaning a filter structure that has been in operation for a long time, the cleaning operation can be carried out while the device is in operation, as follows:

[0036] Taking the conveying operation of the heat medium inlet pipe 2 as an example, the solenoid valve inside the filter valve pipe 7 corresponding to the front end of the heat medium inlet pipe 2 is closed, and at the same time, the solenoid valve inside the diverter valve pipe 8 is opened, thereby diverting the heat fluid medium conveyed through the transition valve pipe 6 to the inside of the diverter valve pipe 8, and then passing through the second filter 11 inside the diverter valve pipe 8 after being filtered, and then passing through the corresponding heat medium inlet pipe 2 into the interior of the heat exchanger body 1, meeting the subsequent cold and heat exchange needs;

[0037] Then, the brake stepper motor 92 corresponding to the front end of the heat medium inlet pipe 2 is started, and the output end of the brake stepper motor 92 drives the support frame 91, the multiple first filter screens 93 inside the support frame 91, and the auxiliary sealing ring 94 to rotate 180 degrees. At the same time, the solenoid valve in the corresponding second filter screen 11 is opened, thereby using the fluid medium transported inside the transition valve pipe 6 to reversely flush the multiple first filter screens 93 after flipping, and the impurity fluid generated after flushing is transported through the corresponding second filter screen 11 to the corresponding heat medium outlet pipe 3 for discharge away from the heat exchanger body 1. After a certain period of time, the brake stepper motor 92 is started, and the output end of the brake stepper motor 92 drives the support frame 91, the multiple first filter screens 93 inside the support frame 91, and the auxiliary sealing ring 94 to reset, opening the solenoid valve inside the filter valve pipe 7 and closing the solenoid valve inside the diverter valve pipe 8, so that the hot fluid medium is filtered again through the transition valve pipe 6 and the filter valve pipe 7 and enters the interior of the heat exchanger body 1;

[0038] Similarly, the conveying operation of the heat medium outlet pipe 3 can also perform a self-cleaning process on the adjustable filter assembly 9 associated with the heat medium outlet pipe 3 according to the above steps.
