Description

Technical Field

[0001] This utility model belongs to the technical field of heat energy converters, specifically relating to a heat transfer oil-powered heat energy converter. Background Technology

[0002] In traditional heating energy converter designs, water heating systems, using hot water or steam as the heat source, are widely adopted. These systems typically include a boiler and a series of pipes, heating water by burning fuel or using electric heating elements to produce hot water or steam, which is then transferred to the user through the pipes. However, this traditional heating method has some limitations in terms of efficiency, safety, and environmental friendliness.

[0003] Traditional water-heating thermal energy converters typically experience significant heat loss during heat exchange because water has a high specific heat capacity, requiring more energy to heat the same amount of water. Furthermore, the heat transfer efficiency of water vapor is lower than that of heat transfer oil, resulting in low overall thermal efficiency. Water heating systems also require a long time to reach operating temperature after startup, leading to slow response times and unsuitability for rapid temperature control. Even in standby mode, heat loss continues as the water needs to maintain a certain temperature, resulting in high standby energy consumption.

[0004] In view of this, we propose a heat transfer oil-based heat energy converter, which effectively overcomes the above-mentioned defects by using heat transfer oil instead of water vapor as a heat source, and provides a more efficient, safer and more environmentally friendly heating method. Utility Model Content

[0005] The present invention aims to solve the technical problem that in the prior art, the water heating system of the water heating heat energy converter usually has high heat loss during the heat exchange process, and the water heating system takes a long time to reach the working temperature from start-up, resulting in high standby power consumption.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat exchanger powered by heat transfer oil includes an outer casing and a core. The outer casing includes a control box located on the upper layer and an installation box located on the lower layer. The core is installed in the installation box and is a double-tank heat exchanger. The double-tank structure of the core includes a heat exchange chamber and a heating inner tank connected to the heat exchange chamber. Heat transfer oil is injected into the heating inner tank and the heat exchange chamber.

[0008] The heat exchange chamber is connected to an inlet and an outlet, which are connected to the serpentine heat exchange tubes inside the heat exchange chamber; an electric heating tube for heating the heat transfer oil is installed inside the heating tank.

[0009] The heat-conducting oil in the heating inner container and the heat exchange chamber absorbs heat through the electric heating pipe, so that the temperature of the heat-conducting oil is increased. Cold water flows into the serpentine heat exchange pipe through the water inlet. The high-temperature heat-conducting oil flows in the heat exchange chamber and transfers heat to the cold water flowing through the wall of the serpentine heat exchange pipe. The cold water is heated in the serpentine heat exchange pipe and then flows out of the water outlet as hot water for use by users.

[0010] The temperature of the heat-conducting oil in the heat exchange chamber is controlled below 170℃. The heat-conducting oil is used instead of traditional water vapor as a heat source. The cooling time of the heat-conducting oil is long, that is, the cooling speed of the entire heat-conducting oil heating heat energy converter is slow, so that the standby time of the heat-conducting oil heating heat energy converter is long. In the 24-hour use of the heat-conducting oil heating heat energy converter, the start-up time is short and the standby time is long. Therefore, heating can be more energy-saving.

[0011] Preferably, the installation box is provided with a box door hinged on one side by a hinge and locked on the other side by a lock. The box door can be conveniently opened and closed, facilitating maintenance and repair of the internal components.

[0012] Preferably, the water inlet and the water outlet are both provided through the outer machine box. The provision of the water inlet and the water outlet makes the pipeline connection simpler, reducing the installation difficulty and time.

[0013] Preferably, the outer machine box and the heating inner container are fixedly provided with mounting ports for mounting the electric heating pipe. The provision of the mounting ports makes the installation and replacement of the electric heating pipe more convenient and fast.

[0014] Preferably, the bottom wall of the outer machine box is fixedly provided with a support for mounting and fixing the machine core. The left and right side walls of the outer machine box are provided with limiting blocks A for limiting and positioning the machine core. The rear wall of the outer machine box is provided with limiting blocks B for limiting and positioning the machine core. The support and the limiting blocks ensure the accurate position of the machine core during installation.

[0015] Preferably, the top of the heating inner container and the heat exchange chamber is respectively provided with a pressure relief valve and a filling port. The pressure relief valve can prevent the internal pressure of the system from being too high, improving the safety of the equipment. The filling port makes it more convenient to add heat-conducting oil when needed.

[0016] Preferably, a temperature sensor extending into the heat exchange chamber is mounted and fixed on the heat exchange chamber for monitoring the temperature of the heat-conducting oil in the heat exchange chamber. A temperature controller and a control circuit board are installed in the control box. The temperature controller receives signals from the temperature sensor and controls the heating process of the entire system according to the set temperature parameters. The control circuit board serves as the control center of the system, receives instructions from the temperature controller, and controls the operation of the electric heating pipe and the water pump. The electric heating pipe is installed in the heating inner container and is controlled to start and stop by signals received by the control circuit board, thereby heating the heat-conducting oil. The water pump is used to circulate water in the water system and is controlled to start and stop by signals received by the control circuit board.

[0017] Compared with the prior art, the technical effects and advantages of the utility model are:

[0018] The heat-conducting oil heating heat energy converter realizes efficient heat energy conversion through the cooperative work of the outer machine box and the machine core. The outer machine box is divided into an upper control box and a lower installation box, and the machine core is a double-inner-tank heat exchanger, including a heat exchange chamber and a heating inner tank, which are connected and filled with heat-conducting oil. The electric heating pipe heats the heat-conducting oil to increase its temperature, and cold water flows through the serpentine heat exchange pipe in the heat exchange chamber, and the heat-conducting oil transfers heat to the cold water through the pipe wall, thereby heating the cold water into hot water for user use. The temperature sensor monitors the temperature of the heat-conducting oil in real time to ensure safe operation of the system.

[0019] The heat-conducting oil heating heat energy converter has a long cooling time for heat-conducting oil heating, so that the heat energy converter has a slow cooling speed and a long standby time, and therefore in a 24-hour use cycle, the heat energy converter has a short start-up time and a long standby time, which can significantly save power compared with traditional heating methods. At the same time, by controlling the temperature of the heat-conducting oil below 170℃, the safety risk in the operation of the equipment is reduced, and the safety of the equipment is improved.

[0020] The heat-conducting oil heating heat energy converter uses heat-conducting oil as a heat source, and its thermal efficiency is usually higher than that of water vapor, which can more effectively utilize energy. In addition, using heat-conducting oil instead of water vapor as a heat source can reduce the impact on the environment, such as reducing the impact of water vapor emissions on the atmosphere, thereby realizing a more environmentally friendly heating method. The overall design is compact, reducing the difficulty and time of installation, and improving the overall appearance and neatness of the product. BRIEF DESCRIPTION OF DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.

[0027] The drawings will be described below in conjunction with the drawings of the embodiments of the utility model. Figures 1-4 The application will be further described in detail,

[0028] The embodiment of the application discloses a heat-conducting oil heating heat energy converter, which comprises an outer case 1 and a core 2, the outer case 1 comprises a control box 101 located at the upper layer and a mounting box 102 located at the lower layer; the mounting box 102 is provided with a box door 104 which is hinged on one side through a hinge and locked on the other side through a lock catch 103. Through the design of the hinge and the lock catch 103, the box door 104 can be conveniently opened and closed, and the internal components can be conveniently maintained and overhauled. The lock catch 103 can ensure that the box door 104 remains closed during transportation and operation, preventing accidental contact with the internal components.

[0029] The core 2 is installed in the mounting box 102 and is a double-internal-container heat exchanger, a support 106 for installing and fixing the core 2 is fixed on the bottom wall of the outer case 1, limiting blocks A 107 for limiting and positioning the core 2 are arranged on the left and right side walls of the outer case 1, and limiting blocks B 108 for limiting and positioning the core 2 are arranged on the rear wall of the outer case 1. The support 106 and the limiting blocks ensure the accurate position of the core 2 during installation, improving the stability of the system. The design of the limiting blocks is helpful for the rapid installation and alignment of the core 2.

[0030] The double-internal-container structure of the core 2 comprises a heat exchange chamber 201 and a heating internal container 202 communicated with the heat exchange chamber 201, and the heating internal container 202 and the heat exchange chamber 201 are filled with heat-conducting oil;

[0031] The heat exchange chamber 201 is connected with a water inlet 203 and a water outlet 204, both of which are arranged through the outer machine box 1. The arrangement of the water inlet 203 and the water outlet 204 makes the pipeline connection simpler, reduces the installation difficulty and time, and makes the overall design more compact, improving the overall appearance and neatness of the product. The water inlet 203 and the water outlet 204 are connected with the heat exchange chamber 201 and the serpentine heat exchange pipe 205 inside; the heating inner container 202 is provided with an electric heating pipe 206 for heating the heat conducting oil; the outer machine box 1 and the heating inner container 202 are fixedly provided with a mounting port 105 for mounting the electric heating pipe 206. The arrangement of the mounting port 105 makes the installation and replacement of the electric heating pipe 206 more convenient and fast, reducing the difficulty during maintenance and thus reducing the maintenance cost.

[0032] The heat conducting oil in the heating inner container 202 and the heat exchange chamber 201 absorbs heat through the electric heating pipe 206, so that the temperature of the heat conducting oil rises. Cold water flows into the serpentine heat exchange pipe 205 through the water inlet 203. The high-temperature heat conducting oil flows in the heat exchange chamber 201 and transfers heat to the cold water flowing through the wall of the serpentine heat exchange pipe 205. The cold water is heated in the serpentine heat exchange pipe 205 and then flows out of the water outlet 204 as hot water for use by the user.

[0033] The heating inner container 202 and the top of the heat exchange chamber 201 are respectively provided with a pressure relief valve 207 and a filling port 208. The pressure relief valve 207 can prevent the internal pressure of the system from being too high, improving the safety of the equipment. The filling port 208 makes it more convenient to add heat conducting oil when needed.

[0034] A temperature sensor 209 extending into the heat exchange chamber 201 is installed and fixed on the heat exchange chamber 201 for monitoring the temperature of the heat conducting oil in the heat exchange chamber 201. A temperature controller and a control circuit board are installed in the control box 101. The temperature controller receives signals from the temperature sensor 209 and controls the heating process of the entire system according to the set temperature parameters. The control circuit board, as the control center of the system, receives instructions from the temperature controller and controls the operation of the electric heating pipe 206 and the water pump. The electric heating pipe 206 is installed in the heating inner container 202 and is controlled to start and stop by signals received by the control circuit board, thereby heating the heat conducting oil. The water pump is used to circulate water in the water system and is controlled to start and stop by signals received by the control circuit board. The temperature sensor 209 can monitor the temperature of the heat conducting oil in real time, ensuring that the system operates at the set temperature parameters. The combination of the temperature controller and the control circuit board realizes automatic control of the system, improves efficiency, and reduces manual intervention. Precise control of the operation of the electric heating pipe 206 can save energy and reduce operating costs. Real-time monitoring and automatic control help to prevent safety hazards such as overheating, improving the safety of the equipment.

[0035] The temperature of the heat-conducting oil in the heat exchange chamber 201 is controlled below 170°C. The heat-conducting oil is used instead of traditional water vapor as the heat source. The cooling time of the heat-conducting oil is long, i.e., the cooling speed of the entire heat-conducting oil heating energy converter is slow, resulting in a long standby time of the heat-conducting oil heating energy converter. In the 24-hour use of the heat-conducting oil heating energy converter, the startup time is short and the standby time is long. Therefore, the heating and warming process can save more electricity.

[0036] The heat-conducting oil heating energy converter is composed of an outer case 1 and a core 2. The outer case 1 is divided into an upper control box 101 and a lower installation box 102. The core 2 is a double-internal-tank heat exchanger installed in the installation box 102. The core 2 includes a heat exchange chamber 201 and a heating internal tank 202, which are connected.

[0037] The heat exchange process is as follows:

[0038] Heating: The heating internal tank 202 is internally provided with an electric heating pipe 206 for heating the heat-conducting oil.

[0039] Heat exchange: The heat exchange chamber 201 is provided with a water inlet 203 and a water outlet 204, which are connected to the serpentine heat exchange pipe 205 in the heat exchange chamber 201. Cold water enters the serpentine heat exchange pipe 205 from the water inlet 203, while high-temperature heat-conducting oil flows in the heat exchange chamber 201. The high-temperature heat-conducting oil transfers heat to the cold water through the wall of the serpentine heat exchange pipe 205, causing the cold water to heat up into hot water, which then flows out from the water outlet 204.

[0040] Temperature control: The temperature of the heat-conducting oil in the heat exchange chamber 201 is controlled below 170°C to ensure safety and efficiency.

[0041] The cooling time of the heat-conducting oil is relatively long, resulting in a slow cooling speed of the energy converter and a long standby time. In the 24-hour use cycle, the energy converter has a short startup time and a long standby time. Therefore, compared with traditional heating methods, using heat-conducting oil as the heat source can significantly save electricity. The heat efficiency of heat-conducting oil as the heat source is generally higher than that of water vapor, so it can utilize energy more effectively. By controlling the temperature of the heat-conducting oil within a safe range (below 170°C), the safety risk during equipment operation can be reduced. Using heat-conducting oil instead of water vapor as the heat source can reduce the impact on the environment, such as reducing the impact of water vapor emissions on the atmosphere. Overall, the design of this heat-conducting oil heating energy converter provides an efficient, electricity-saving, safe, and environmentally friendly heating method.

[0042] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
