Description

Technical Field

[0001] This utility model relates to a high-flow-rate heater. Background Technology

[0002] Most water heating devices on the market currently use a single heating module structure, whose basic structure usually includes an inlet end cap, a heating element, and an outlet end cap.

[0003] In existing technologies, heating modules typically consist of only one set of heating tubes and a heat dissipation structure. Heat exchange occurs through water flow along the inner cavity of the heating tubes to achieve the water heating function. While this type of structure can meet basic requirements in low-flow, low-heat-load applications, it has significant shortcomings in practical applications with high flow rates and large heat loads. For example, when a single heating module handles a large flow of water, the short contact time between the water and the heating element leads to insufficient heat exchange, resulting in an unsatisfactory water temperature increase. Utility Model Content

[0004] The purpose of this invention is to provide a high-flow-rate heater that improves the efficiency of water heating.

[0005] The purpose of this utility model is achieved as follows:

[0006] A high-flow-rate heater includes an inlet end cap, a heating device, an outlet end cap, and a flow reversing end cap. The heating device includes a first heating module and a second heating module. The first heating module includes a hollow heat dissipation shell and a heating tube that are connected from front to back. The heating tube is placed inside the hollow heat dissipation shell. The inlet of the heating tube protrudes from the front port of the hollow heat dissipation shell, and the outlet of the heating tube protrudes from the rear port of the hollow heat dissipation shell. The inlet and outlet are connected to the inner cavity of the heating tube. The heating tube heats the water passing through the inner cavity of the heating tube. The second heating module has the same structure as the first heating module.

[0007] The first heating module and the second heating module are assembled together;

[0008] The water inlet end cap is provided with a water inlet nozzle. The water inlet end cap is located at the front port of the hollow heat dissipation shell of the first heating module and closes the front port. The water inlet nozzle is connected to the water inlet of the heating tube body of the first heating module.

[0009] The water flow reversing end cover is provided with a water flow reversing cavity. The water flow reversing end cover has an inlet port and a drain port that connect to the water flow reversing cavity. The rear port of the hollow heat dissipation shell of the first heating module and the front port of the hollow heat dissipation shell of the second heating module are connected to the water inlet end cover. The water inlet end cover closes the rear port of the hollow heat dissipation shell of the first heating module and the front port of the hollow heat dissipation shell of the second heating module. The outlet of the heating tube of the first heating module is connected to the water inlet port, and the inlet of the heating tube of the second heating module is connected to the drain port.

[0010] The water outlet cap is provided with a water outlet nozzle. The water outlet cap is located at the rear port of the hollow heat dissipation shell of the second heating module and closes the rear port. The water outlet nozzle is connected to the water outlet of the heating tube body of the second heating module.

[0011] The dual-module structure allows water to be heated sequentially in two sets of heating tubes, increasing the contact area between the water and the heating elements and the heating time, thus making the heating effect more obvious and meeting the requirements of large flow and high temperature rise.

[0012] Through the rational design of the inlet end cap, reversing end cap and outlet end cap, the water flow is evenly distributed between the two heating modules, preventing water flow short circuits or dead zones, and ensuring more sufficient and uniform heat transfer.

[0013] The dual-module assembly structure ensures a balanced distribution of heat load among the heating modules, preventing localized overheating caused by excessive load on a single module, thereby improving the overall safety and service life of the equipment.

[0014] In summary, this high-flow-rate heater design ensures efficient heating while also taking into account water flow distribution and heat load balance, providing a practical technical solution for achieving efficient, stable, and safe water heating.

[0015] The objective of this utility model can also be achieved by the following technical measures:

[0016] Furthermore, the first heating module also includes a temperature controller. The hollow heat dissipation shell has an installation port, and the temperature controller is installed inside the installation port. The temperature sensing end of the temperature controller contacts the heating tube.

[0017] The temperature controller is integrated into the first heating module. By opening an installation port on the hollow heat dissipation shell, the temperature controller can be tightly installed inside the first heating module. Moreover, the temperature sensing end of the temperature controller directly contacts the heating tube, which can accurately sense the temperature change of the heating tube in real time. This improves the temperature monitoring accuracy and response speed of the temperature control system and ensures the safety and stability of the heating process.

[0018] Furthermore, it also includes a first thermocouple for measuring the inlet water temperature, the first thermocouple being disposed on the inlet end cap, with the temperature sensing end of the first thermocouple located inside the inlet nozzle.

[0019] A first thermocouple is installed on the water inlet cap, with its temperature sensing end located inside the water inlet. It can measure the water inlet temperature in real time, providing water inlet temperature information to the temperature control system. This helps to optimize the heating process and energy management, improve heating efficiency, and enhance the overall safety and reliability of the system.

[0020] Furthermore, it also includes a second thermocouple for measuring the outlet water temperature, the second thermocouple being disposed on the outlet end cap, with the temperature sensing end of the second thermocouple located inside the outlet nozzle.

[0021] A second thermocouple is installed on the water outlet cover, with its temperature sensing end located inside the water outlet nozzle. It monitors the water temperature in real time and can monitor and adjust the heating effect by providing feedback on the water temperature, ensuring that the water temperature meets the set requirements. This also helps prevent overheating and improves the safety and thermal efficiency of the equipment.

[0022] Furthermore, the water outlet cover includes a front cover for water flow reversing, a rear cover for water flow reversing, and a sealing ring. The front face of the front cover for water flow reversing has the water inlet port and the water outlet port. The rear face of the front cover for water flow reversing has a confluence port connecting the water inlet port and the water outlet port. The rear cover for water flow reversing has the water flow reversing cavity. The front cover for water flow reversing and the rear cover for water flow reversing are assembled. The confluence port is inserted into the water flow reversing cavity. The sealing ring is disposed between the front cover for water flow reversing and the rear cover for water flow reversing, and the sealing ring seals the gap between the confluence port and the water flow reversing cavity.

[0023] The outlet end cover adopts a combination design of a front end cover for water flow reversal, a rear end cover for water flow reversal, and a sealing ring. The front and rear ends of the front end cover for water flow reversal are respectively provided with an inlet port, a drain port, and a confluence port. This structure effectively prevents water leakage by reasonably connecting the confluence port and the water flow reversal cavity, and seals the gap between the two with the sealing ring, ensuring the water flow reversal and mixing effect, thereby improving the uniformity of heat transfer and the sealing performance of the heating system.

[0024] Furthermore, the first heating module also includes a locking clamp and a rivet. The locking clamp is provided with a clamping cavity for clamping the heating tube body. An upper clamping plate and a lower clamping plate are provided at the entrance of the clamping cavity. An opening is formed between the upper clamping plate and the lower clamping plate to facilitate the passage of the heating tube body.

[0025] The heating tube body passes through the opening and enters the clamping cavity. The rivet passes through the upper clamping plate and the lower clamping plate to close the opening and lock the clamping cavity, thereby reducing the size of the clamping cavity so that the clamping cavity clamps the heating tube body.

[0026] The first heating module is equipped with a locking clamp and rivet structure. The locking clamp has a clamping cavity, which, together with the opening formed by the upper clamping plate and the lower clamping plate, allows the heating tube to pass through smoothly. The opening is closed by the upper clamping plate and the lower clamping plate through the rivet, so as to achieve tight clamping of the heating tube.

[0027] Furthermore, the temperature controller includes a housing, a bimetallic strip, a push rod, a first terminal, a conductive spring, a second terminal, and a ceramic plate, wherein the conductive spring is placed inside the housing;

[0028] The first terminal is placed inside the housing, one end of the first terminal is connected to a conductive spring, and the other end of the first terminal extends out of the housing to form a first wiring terminal.

[0029] The second terminal is placed inside the housing, with one end of the second terminal located above the conductive spring to form a contact end, and the other end of the second terminal extending out of the housing to form a second wiring terminal;

[0030] The bimetallic strip and push rod are housed within the housing, with one end of the push rod abutting against the conductive spring and the other end abutting against the bimetallic strip.

[0031] The shell has an opening corresponding to the bimetallic strip. The ceramic strip is placed inside the shell, with one end of the ceramic strip abutting against the bimetallic strip and the other end of the ceramic strip extending out of the opening to form a heat-conducting part.

[0032] As a good insulating material, ceramic discs play an effective insulating role in thermostats. They can prevent electrical conductivity risks and thus avoid safety hazards such as electrical short circuits or fires that may be caused by the thermostat coming into contact with high-temperature components.

[0033] The ceramic plate not only has excellent insulation properties but also high thermal conductivity. Placed inside the thermostat and in contact with the bimetallic strip, it facilitates rapid heat conduction, thereby improving the thermostat's response speed and control accuracy. This ensures that the thermostat can quickly adjust and accurately control the circuit's on / off state in response to temperature changes.

[0034] Compared to other thermostats that require complex insulation and thermal isolation designs, this device achieves both thermal insulation and thermal insulation functions through a simple ceramic plate structure, reducing manufacturing costs and simplifying design and production processes.

[0035] The beneficial effects of this utility model are as follows:

[0036] This invention features a dual-module structure that allows water to be heated sequentially in two sets of heating tubes, increasing the contact area and heating time between the water and the heating elements, thereby resulting in a more significant heating effect and meeting the requirements for high flow rates and high temperatures.

[0037] This utility model, through the rational design of the inlet end cap, the reversing end cap and the outlet end cap, achieves a uniform distribution of water flow between the two heating modules, prevents water flow short circuits or dead zones, and ensures more sufficient and uniform heat transfer.

[0038] This invention features a dual-module assembly structure that ensures a balanced distribution of heat load among the heating modules, preventing localized overheating of a single module due to excessive load, thereby improving the overall safety and service life of the equipment.

[0039] This utility model adopts a combination design of a front end cover for water flow reversal, a rear end cover for water flow reversal, and a sealing ring. The front and rear ends of the front end cover for water flow reversal are respectively provided with an inlet port, a drain port, and a confluence port. This structure effectively prevents water leakage by reasonably connecting the confluence port and the water flow reversal cavity, and seals the gap between the two with the sealing ring, ensuring the water flow reversal and mixing effect, thereby improving the uniformity of heat transfer and the sealing performance of the heating system.
