Description

Technical Field

[0001] This utility model relates to the technical field of integrated heating equipment devices, and in particular to modular heat exchange devices. Background Technology

[0002] In existing heat exchange technologies, traditional heat exchange devices typically employ fixed structural designs, making it difficult to meet diverse application scenarios and flexible installation requirements. For example, while common plate heat exchangers and spiral heat exchangers offer advantages in efficiency and compactness, in practical applications they often require customized designs based on specific system needs. This not only increases costs but also limits their versatility across different scenarios.

[0003] In existing heat exchange devices, when connecting heating systems and heating equipment, the heating water is directly introduced into the heating equipment, which may lead to excessive water pressure and prevent the expulsion of gas inside the heating equipment, affecting system safety and service life. Therefore, it is necessary to improve the existing devices. Utility Model Content

One end of the inlet pipe is connected to a pump, and the upper end of the pump is connected to a diversion pipe. The upper end of the diversion pipe is connected to the bottom wall of the buffer water tank, and the bottom wall of the buffer water tank is also connected to a cold water inlet pipe.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figure 1 As shown, this utility model is a modular heat exchange device, including...

[0024] Cabin 1;

[0025] Buffer water tank 2, which is installed inside the cabin 1;

[0026] The chamber 1 is equipped with a plate heat exchanger 3. A heating inlet pipe 4 and a heating return pipe 5 are connected to one side of the plate heat exchanger 3. An outlet pipe 6 and an inlet pipe 7 are connected to the other side of the plate heat exchanger 3. A pump 8 is connected to one end of the inlet pipe 7. A diversion pipe 9 is connected to the upper end of the pump 8. The upper end of the diversion pipe 9 is connected to the bottom wall of the buffer water tank 2. A cold water inlet pipe 10 is also connected to the bottom wall of the buffer water tank 2.

[0027] An installation plate 11 is fixedly connected to one side wall inside the cabin 1, and the plate heat exchanger 3 is fixedly installed on the upper wall of the installation plate 11.

[0028] An installation frame 12 is fixedly connected to one side wall inside the cabin 1, and the pump 8 is fixedly mounted on the installation frame 12.

[0029] A first temperature sensor 15 is installed on the heating water inlet pipe 4, and a second temperature sensor 20 is installed on the hot water outlet pipe 14. An integrated controller 16 is installed on the outside of the cabin 1, which is electrically connected to the pump 8, the heater 13, the first temperature sensor 15, and the second temperature sensor 20.

[0030] The buffer water tank 2 is provided with a tank cover 17, and a water filling pipe 18 is connected to the tank cover 17. A water level sensor 19 is fixedly connected to one side wall inside the buffer water tank 2. The water level sensor 19 is electrically connected to the integrated controller 16, and the integrated controller 16 is provided with an alarm module.

[0031] As can be seen from the above, when the heating water enters the heating inlet pipe 4, the first temperature sensor 15 detects the temperature change information. The integrated controller 16, which is electrically connected to the first temperature sensor 15, starts the pump 8. The pump 8 then guides the hot water into the plate heat exchanger 3 for heat exchange. The water after heat exchange is transported to the heating equipment through the outlet pipe 6. After circulating through the heating equipment, it enters the cold water inlet pipe 10 and then enters the buffer water tank 2. During this process, the gas inside the heating equipment is carried into the buffer water tank 2 through the water to discharge the gas inside the heating equipment. Then, the gas enters the plate heat exchanger 3 through the drain pipe 9 and the inlet pipe 7 in sequence, and then is discharged through the heating return pipe 5 for the next cycle.

[0032] When the water level inside the buffer tank 2 is insufficient, the water level sensor 19 sends a signal to the integrated controller 16. The integrated controller 16 is equipped with an alarm module, which is activated to issue an alarm, so as to alert personnel to add water in time.

[0033] The modular heat exchange device of this utility model exchanges heat with the heating water before it is delivered to the heating equipment. The device of this utility model is open, which effectively eliminates the problem of pressure in the heating water. The structure design is user-friendly.

[0034] Example 2:

[0035] Please see Figures 2-3 As shown, this utility model is a modular heat exchange device, including...

[0036] Cabin 1;

[0037] Buffer water tank 2, which is installed inside the cabin 1;

[0038] The chamber 1 is equipped with a plate heat exchanger 3. A heating inlet pipe 4 and a heating return pipe 5 are connected to one side of the plate heat exchanger 3. An outlet pipe 6 and an inlet pipe 7 are connected to the other side of the plate heat exchanger 3. A pump 8 is connected to one end of the inlet pipe 7. A diversion pipe 9 is connected to the upper end of the pump 8. The upper end of the diversion pipe 9 is connected to the bottom wall of the buffer water tank 2. A cold water inlet pipe 10 is also connected to the bottom wall of the buffer water tank 2.

[0039] An installation plate 11 is fixedly connected to one side wall inside the cabin 1, and the plate heat exchanger 3 is fixedly installed on the upper wall of the installation plate 11.

[0040] An installation frame 12 is fixedly connected to one side wall inside the cabin 1, and the pump 8 is fixedly mounted on the installation frame 12.

[0041] One end of the outlet pipe 6 is connected to a heater 13, and the other end of the heater 13 is connected to a hot water outlet pipe 14.

[0042] A first temperature sensor 15 is installed on the heating water inlet pipe 4, and a second temperature sensor 20 is installed on the hot water outlet pipe 14. An integrated controller 16 is installed on the outside of the cabin 1, which is electrically connected to the pump 8, the heater 13, the first temperature sensor 15, and the second temperature sensor 20.

[0043] The buffer water tank 2 is provided with a tank cover 17, and a water filling pipe 18 is connected to the tank cover 17.

The water level sensor 19 is electrically connected to the integrated controller 16, and the integrated controller 16 is provided with an alarm module.

[0044] As can be seen from the above, based on Embodiment 1, a heater 13 structure has been further added. In order to prevent the water temperature after heat exchange from being insufficient, the heater 13 is set to facilitate the heating treatment of the water after heat exchange. Specifically, when the water after heat exchange is discharged through the outlet pipe 6, the water temperature is detected by the second temperature sensor 20. When the temperature is insufficient, the integrated controller 16 controls the heater 13 to start heating, so that the water is heated to a constant temperature. During this process, the water temperature is continuously monitored by the second temperature sensor 20 to ensure that the water temperature is constant.
