Description

Technical Field

[0001] This utility model relates to the field of instrument and meter control technology, and in particular to a temperature control device. Background Technology

[0002] Carbon dioxide is a colorless, odorless, and tasteless gas at room temperature. Its chemical formula is CO, and its formula weight is 44.01. It is one of the carbon oxides, commonly known as carbonic acid, and also called carbonic anhydride or carbon anhydride.

[0003] Carbon dioxide typically needs to be stored in a container (such as a storage tank). During use, it is often necessary to monitor the temperature of the carbon dioxide inside the storage tank so that the temperature can be adjusted according to the real-time temperature to achieve the required temperature.

[0004] For gaseous carbon dioxide stored in the tank, temperature can be detected by sampling. However, the temperature measuring mechanism is usually fixed by welding, which makes it impossible to disassemble and reassemble the mechanism, and inconvenient for maintenance, replacement and other operations.

The temperature measuring element is used to measure the temperature signal of carbon dioxide inside the housing.

[0009] A temperature control mechanism is attached to the outer periphery of the storage tank and is used to heat the storage tank to regulate the temperature of carbon dioxide inside the storage tank;

[0010] The installation mechanism includes multiple connectors and a pressure plate detachably connected to the outer periphery of the storage tank. The multiple connectors are spaced apart along the circumference of the storage tank, and the opposite ends of each connector are respectively connected to the box body and the pressure plate so that the box body is pressed against the top of the storage tank.

[0011] In some embodiments, the pressure plate is provided with a through hole, one end of the connector is connected to the housing, and the other end passes through the through hole from top to bottom and then extends upward to be detachably connected to the outside of the pressure plate.

[0012] In some embodiments, the installation mechanism includes a limiting ring that is movably fitted around the outer periphery of the storage tank, and the limiting ring is located below the pressure plate. One end of the connector is connected to the housing, and the other end passes around the limiting ring and is connected to the pressure plate.

[0013] In some embodiments, the storage tank includes a tank body and an upper end cap and a lower end cap located at the upper and lower ends of the tank body;

[0014] The connecting ring is sleeved on the lower end cap, and the inner diameter of the connecting ring is smaller than the outer diameter of the tank body or the upper part of the lower end cap.

[0015] In some embodiments, the installation mechanism includes a plurality of pressure plates, which are arranged circumferentially around the outer periphery of the storage tank, and the plurality of pressure plates are correspondingly provided with a plurality of connecting members.

[0016] The installation mechanism also includes multiple hooks, with at least one hook provided on each pressure plate; one end of each connector is fixedly connected to the box body, and the other end is hooked to the hook on the corresponding pressure plate.

[0017] In some embodiments, each of the pressure plates is provided with at least two hooks spaced vertically along its length, and each of the connectors is hooked to one of the hooks on the corresponding pressure plate.

[0018] In some embodiments, a plurality of the connectors are arranged at uniform intervals along the circumference of the storage tank;

[0019] Each of the aforementioned connectors is made of multiple thin steel wires bundled together.

[0020] In some embodiments, the temperature measuring mechanism further includes an exhaust fan, which is disposed inside the box and connected to the inlet pipe. The exhaust fan is used to draw carbon dioxide from inside the storage tank into the box.

[0021] In some embodiments, the temperature regulating mechanism is located between the pressure plate and the storage tank; the pressure plate extends circumferentially outward beyond the outer periphery of the temperature regulating mechanism.

[0022] The portion of the pressure plate extending outward beyond the temperature regulating mechanism is fitted to the outer periphery of the storage tank and detachably connected to the storage tank; and / or, the portion of the pressure plate extending outward beyond the temperature regulating mechanism is sealed to the outer periphery of the storage tank.

[0025] In this application, the housing of the temperature measuring mechanism is connected and fixed to a pressure plate that is detachably connected to the outer periphery of the storage tank through multiple connectors, so that the housing is pressed tightly against the top of the storage tank. Furthermore, since the multiple connectors are arranged at intervals along the circumference of the storage tank, the housing can be circumferentially fixed, thereby achieving a firm fixation of the housing. At the same time, the above design also makes it easy to disassemble the temperature measuring mechanism from the storage tank. The structure is simple and the operation is convenient and easy.

[0026] Furthermore, because the storage tank, outlet pipe, casing, and inlet pipe form a circulation path, carbon dioxide in the storage tank can enter the casing for temperature detection by the temperature sensor, thus obtaining the carbon dioxide temperature signal. After temperature detection, the carbon dioxide in the casing can also flow back into the storage tank, thereby achieving the purpose of carbon dioxide circulation between the storage tank and the casing. After temperature detection, when the carbon dioxide temperature drops, the storage tank can be heated by the temperature control mechanism to raise the temperature of the carbon dioxide inside until the temperature is maintained at the required level, thereby achieving the purpose of temperature control.

[0036] This application provides a temperature control device, which will be described using an example of regulating the temperature of carbon dioxide inside a storage tank. The carbon dioxide is in a gaseous state. Of course, this temperature control device can also be used for temperature regulation of other gases.

[0037] The storage tank is a vertical tank. Specifically, the tank includes a tank body and upper and lower end caps located at both ends of the tank body along its axial direction. The tank body is cylindrical, with its axis extending vertically. The inner diameters of the upper and lower end caps gradually increase towards the tank body. Both the upper and lower end caps can be hemispherical, dish-shaped, or similar shapes.

[0038] The storage tank also includes a neck, which is located on top of the upper head and communicates with the interior of the tank body.

[0039] The storage tank also includes a support frame located at the bottom of the lower head to support the tank so that it can be placed in an upright position.

[0040] The following detailed description, in conjunction with the accompanying drawings, describes specific embodiments of the temperature control device of this application.

[0041] Figure 1 This is a schematic diagram of the temperature control device in this embodiment. Figure 2 This embodiment presents a partial structural diagram of the temperature control device. Figure 3 This is a partial exploded view of the temperature control device in this embodiment.

[0042] refer to Figures 1-3 The temperature control device includes a temperature measuring mechanism 1, a temperature adjusting mechanism 2, and an installation mechanism 3. The temperature measuring mechanism 1 includes a housing 11, a temperature measuring element 12, and an inlet pipe 13 and an outlet pipe 14 disposed within the housing 11. The housing 11 is located on the top of the storage tank 100. The inlet pipe 13 and the outlet pipe 14 are both connected to the interior of the storage tank 100, forming a circulation path with the storage tank 100, the outlet pipe 14, the housing 11, and the inlet pipe 13. The temperature measuring element 12 is used to measure the temperature signal of the carbon dioxide inside the housing 11. The temperature adjusting mechanism 2 is attached to the outer periphery of the storage tank 100 and is used to heat the storage tank 100 to adjust the temperature of the carbon dioxide inside. The installation mechanism 3 includes multiple connectors 31 and a pressure plate 32 detachably connected to the outer periphery of the storage tank 100. The multiple connectors 31 are spaced apart along the circumference of the storage tank 100, and the opposite ends of each connector 31 are connected to the housing 11 and the pressure plate 32 respectively, pressing the housing 11 tightly against the top of the storage tank 100.

[0043] In this application, the housing 11 of the temperature measuring mechanism 1 is connected and fixed to a pressure plate 32 that is detachably connected to the outer periphery of the storage tank 100 by a plurality of connectors 31, so that the housing 11 is pressed tightly against the top of the storage tank 100. Furthermore, since the plurality of connectors 31 are arranged at intervals along the circumference of the storage tank 100, the housing 11 can be circumferentially fixed, thereby achieving a firm fixation of the housing 11. At the same time, the above design also makes it convenient to disassemble the temperature measuring mechanism 1 from the storage tank 100, and the operation is convenient and simple.

[0044] Furthermore, since the storage tank 100, outlet pipe 14, box 11, and inlet pipe 13 form a circulation path, carbon dioxide in the storage tank 100 can enter the box 11 for temperature detection by the temperature sensor 12, thereby obtaining the carbon dioxide temperature signal. After temperature detection, the carbon dioxide in the box 11 can also flow back into the storage tank 100, thus achieving the purpose of circulating carbon dioxide within the storage tank 100 and the box 11. After temperature detection, when the carbon dioxide temperature decreases, the temperature regulating mechanism 2 can heat the storage tank 100 to raise the temperature of the carbon dioxide inside until the temperature is maintained at the required level, thereby achieving the purpose of temperature control.

[0045] refer to Figures 1-3 The temperature measuring mechanism 1 includes a housing 11, a temperature measuring element 12, an inlet pipe 13, and an outlet pipe 14.

[0046] The box body 11 is located on top of the storage tank 100. Specifically, the bottom of the box body 11 is adapted to the shape of the top of the storage tank 100 so that the bottom of the box body 11 can fit tightly against the top of the neck 140 of the storage tank 100. Exemplarily, the box body 11 has an internally hollow cubic structure, and its internal space is used for temporary storage of carbon dioxide. The interior of the box body 11 is a sealed space to prevent carbon dioxide from escaping.

[0047] A temperature sensor 12 is installed on one side wall of the housing 11. Specifically, the temperature sensor 12 includes a measuring end and a display end. The measuring end is located inside the housing 11 to contact the carbon dioxide inside the housing 11 and to obtain the temperature signal of the carbon dioxide inside the housing 11. The display end is located outside the housing 11 and is used to display the temperature signal for easy viewing by personnel.

[0048] Furthermore, the temperature measuring element 12 is sealed to the box body 11 to ensure the airtightness of the box body 11.

[0049] Inlet pipe 13 and outlet pipe 14 are spaced apart within the housing 11, and both inlet pipe 13 and outlet pipe 14 are connected to the interior of the storage tank 100, forming a circulation path between the storage tank 100, outlet pipe 14, housing 11, and inlet pipe 13. This allows carbon dioxide in the storage tank 100 to enter the housing 11 through inlet pipe 13, facilitating temperature detection by the temperature sensor 12 to obtain the carbon dioxide temperature signal. After temperature detection, the carbon dioxide in the housing 11 can also flow back into the storage tank 100 through outlet pipe 14, thus achieving the purpose of circulating carbon dioxide between the storage tank 100 and the housing 11. Specifically, inlet pipe 13 and outlet pipe 14 are spaced apart through the bottom wall of the housing 11 and extend downwards into the storage tank 100. Furthermore, inlet pipe 13 and outlet pipe 14 are sealed to the housing 11 to ensure the airtightness of the interior of the housing 11.

[0050] The temperature measuring mechanism 1 also includes an exhaust fan 15, which is located inside the housing and connected to the inlet pipe 13. The exhaust fan 15 provides power to draw carbon dioxide from inside the storage tank 100 into the housing. Furthermore, during the operation of the exhaust fan 15, the flow rate of carbon dioxide within the storage tank 100 can be increased, accelerating the circulation of carbon dioxide within the storage tank 100 and the housing 11. This allows the temperature measuring element 12 to detect the real-time temperature signal of the carbon dioxide, facilitating real-time monitoring of carbon dioxide temperature changes.

[0051] Optionally, the exhaust fan 15 can be a variable frequency exhaust fan 15, which can adjust the flow rate of carbon dioxide by adjusting its frequency. Of course, the exhaust fan 15 can also be a fixed frequency exhaust fan 15.

[0052] The temperature control mechanism 2 is attached to the outer periphery of the storage tank 100 and is used to heat the storage tank 100 to regulate the temperature of the carbon dioxide inside the storage tank 100. At this time, under the action of the exhaust fan 15, the flow rate of carbon dioxide inside the storage tank 100 can be increased, so that the carbon dioxide inside the storage tank 100 becomes turbulent. Since the characteristics of turbulence are strong vortices and mixing within the fluid, this will significantly destroy the thermal boundary layer (a thin layer with a large temperature gradient in the fluid). The destruction of the boundary layer allows more cold fluid to directly contact the heating surface, while the hot fluid is carried away faster, thereby increasing the heat transfer rate and thus improving the efficiency of the temperature control mechanism 2 in heating carbon dioxide.

[0053] For example, the temperature control mechanism 2 can be composed of multiple heating wires 21, which can be arranged at intervals along the circumference of the storage tank 100. The heating wires 21 are arranged in a serpentine pattern, which increases the length of the heating wires 21 during arrangement, thereby increasing the contact area between the heating wires 21 and the storage tank 100 and improving the heating efficiency. The multiple heating wires 21 are arranged in series.

[0054] In other embodiments, a plurality of heating wires 21 may also be arranged vertically at intervals around the outer periphery of the storage tank 100. In this case, each heating wire 21 may be arranged in a ring around the outer periphery of the storage tank 100.

[0055] In other embodiments, the temperature control mechanism 2 may also consist of a heating wire 21. In this case, the heating wire 21 may be spirally wound around the outer periphery of the storage tank 100 in a vertical direction, or it may be arranged in a serpentine pattern around the outer periphery of the storage tank 100.

[0056] In this embodiment, the installation mechanism 3 is used to install the temperature measuring mechanism 1 and the temperature regulating mechanism 2 onto the storage tank 100.

[0057] First, we will introduce the method of installing the temperature measuring mechanism 1 onto the storage tank 100 via the mounting mechanism 3:

[0058] The mounting mechanism 3 includes multiple connectors 31 and a pressure plate 32. The pressure plate 32 is detachably connected to the outer periphery of the storage tank 100. The multiple connectors 31 are arranged at intervals along the circumference of the storage tank 100, and the opposite ends of each connector 31 are connected to the housing 11 and the pressure plate 32, respectively, thus pressing the housing 11 tightly against the top of the storage tank 100. That is, in this embodiment, the housing 11 of the temperature measuring mechanism 1 is connected and fixed to the pressure plate 32, which is detachably connected to the outer periphery of the storage tank 100, through multiple connectors 31, so that the housing 11 is pressed tightly against the top of the storage tank 100. Furthermore, since the multiple connectors 31 are arranged at intervals along the circumference of the storage tank 100, the housing 11 can be circumferentially fixed, thereby achieving a firm fixation of the housing 11. At the same time, the above design also facilitates the removal of the temperature measuring mechanism 1 from the storage tank 100, making the operation convenient and simple.

[0059] For example, the pressure plate 32 is provided with a through hole 321, the axis of which extends vertically. One end of the connector 31 is connected to the box body 11, and the other end passes through the through hole 321 from top to bottom and then extends upward to be detachably connected to the outside of the pressure plate 32. This allows the through hole 321 of the pressure plate 32 to act as a guide, enabling the connector 31 to extend vertically. After the connector 31 is tightened and fixed to the pressure plate 32, the portion of the connector 31 above the pressure plate 32 can be tightly attached to the upper end cap 120 and the outer periphery of the tank body 110 of the storage tank 100. This allows the connector 31 to be in and maintain a taut state, providing a downward pulling force to the box body 11, so that the box body 11 is firmly fixed to the top of the storage tank 100, improving the stability of the box body 11.

[0060] In other embodiments, the pressure plate 32 may also be disposed on the outside of the connector 31, so that the connector 31 is located between the pressure plate 32 and the storage tank 100. That is, one end of the connector 31 is connected to the box body 11, and the other end extends downward and passes between the pressure plate 32 and the storage tank 100, and then extends upward to connect with the pressure plate 32.

[0061] In other embodiments, one end of the connector 31 is connected to the housing 11, and the other end is directly connected to the top of the pressure plate 32.

[0062] In this embodiment, multiple connectors 31 are evenly spaced along the circumference of the storage tank 100. The multiple connectors 31 arranged in this manner fix the box body 11, which enables the box body 11 to be evenly stressed in the circumference and presses the box body 11 tightly against the top of the storage tank 100, thereby improving the stability of the box body 11.

[0063] The connector 31 is made of multiple thin steel wires bundled together. This design gives the connector 31 a certain degree of flexibility to facilitate the wiring arrangement of the connector 31, while also giving the connector 31 high strength, making it less prone to damage and giving it good durability.

[0064] The number of pressure plates 32 can be multiple, and multiple pressure plates 32 are arranged circumferentially around the outer periphery of the tank body 110 of the storage tank 100. Multiple pressure plates 32 are arranged in a one-to-one correspondence with multiple connecting parts 31.

[0065] The cross-section of the pressure plate 32 is arc-shaped, and its curvature is adapted to the curvature of the tank body 110 so that the pressure plate 32 can fit against the outer periphery of the tank body 110, increasing the contact area between the two, which can improve the connection strength and stability of the pressure plate 32.

[0066] In this embodiment, the installation mechanism 3 may further include a limiting ring 33 movably sleeved around the outer periphery of the storage tank 100, and the limiting ring 33 is located below the pressure plate 32. One end of the connector 31 is connected to the housing 11, and the other end bypasses the limiting ring 33 and connects to the pressure plate 32. Specifically, one end of the connector 31 is connected to the housing 11, and the other end extends downwards and passes through the pressure plate 32 and the limiting ring 33 in sequence, then bypasses the limiting ring 33 outwards and extends upwards to connect with the pressure plate 32. This avoids the connector 31 directly contacting the bottom of the pressure plate 32 after passing through it, and avoiding a taut state after connection, which would exert an upward force on the pressure plate 32 and affect its stability. In other words, the above design uses the limiting ring 33 as a supporting structure for the connector 31 as it extends upwards, ensuring both the stability of the housing 11 and the stability of the pressure plate 32.

[0067] For example, the limiting ring 33 is fitted onto the lower end cap 130 of the storage tank 100. Since the inner diameter of the lower end cap 130 gradually increases towards the tank body 110, this makes it convenient for the limiting ring 33 to be fitted onto the lower end cap 130 from bottom to top.

[0068] Furthermore, the inner diameter of the limiting ring 33 is smaller than the outer diameter of the upper part of the tank body 110 or the lower end cap 130. This means that during the process of fitting the limiting ring 33 onto the lower end cap 130, the difference in size between the inner diameter of the limiting ring 33 and the outer diameter of the upper part of the tank body 110 or the lower end cap 130 will restrict the limiting ring 33 to a certain position on the lower end cap 130, preventing it from moving further upward. At this time, after the connecting piece 31 is wrapped around the limiting ring 33 and extends upward to connect with the pressure plate 32, the connecting piece 31 will provide an upward pulling force to the limiting ring 33, so that the limiting ring 33 is firmly fixed on the lower end cap 130, which can simultaneously ensure the stability of the box body 11, the pressure plate 32, and the limiting ring 33.

[0069] The mounting mechanism 3 also includes multiple hooks 34, with at least one hook 34 on each pressure plate 32. One end of each connector 31 is fixedly connected to the housing 11 of the pressure plate 32, and the other end hooks onto the corresponding hook 34 on the pressure plate 32. Specifically, the hook 34 is L-shaped. The end of the connector 31 used for connecting to the pressure plate 32 is provided with a ring 35. The connector 31 hooks onto the hook 34 through the ring 35, which facilitates disassembly and assembly and makes operation convenient and simple.

[0070] Each pressure plate 32 has at least two hooks 34 spaced vertically along its edge. Each connector 31 engages with one of the hooks 34 on the corresponding pressure plate 32. This ensures that the connector 31 is taut after engaging with the hook 34 by selecting a hook 34 of appropriate height. All hooks 34 on each pressure plate 32 are arranged at equal intervals.

[0071] The following describes a method for installing the temperature control mechanism 2 onto the storage tank 100 using the installation mechanism 3:

[0072] The temperature regulating mechanism 2 is located between the pressure plate 32 and the storage tank 100. That is, the temperature regulating mechanism 2 is pressed against the outer periphery of the storage tank 100 by the pressure plate 32. After the pressure plate 32 is detachably connected to the storage tank 100, the temperature regulating mechanism 2 is fitted and fixed to the outer periphery of the storage tank 100, making operation convenient and simple. At this time, the setting of the connecting piece 31 passing through the through hole 321 of the pressure plate 32 can also avoid interference with the temperature regulating mechanism 2, thus optimizing the layout.

[0073] Furthermore, the pressure plate 32 extends outward circumferentially beyond the outer periphery of the temperature regulating mechanism 2, and is attached to the outer periphery of the storage tank 100, and is detachably connected and / or sealed to the storage tank 100. Specifically, in this embodiment, multiple pressure plates 32 are arranged one-to-one with multiple heating wires 21. Each pressure plate 32 extends outward circumferentially beyond the outer periphery of the corresponding heating wire 21, that is, the pressure plate 32 completely covers the outside of the heating wire 21. After the portion of the pressure plate 32 extending outward from the heating wire 21 is detachably connected and / or sealed to the storage tank 100, it can isolate the heating wire 21 from the outside, thereby playing a heat preservation role and ensuring the heating effect of the heating wire 21 on the storage tank 100. In addition, after removing the pressure plate 32 from the storage tank 100, the heating wire 21 can be removed, which facilitates maintenance and replacement of the heating wire 21, making the operation convenient and simple.

[0074] In other words, the installation mechanism 3 in this application is detachably connected to the storage tank 100 by the pressure plate 32, the storage tank 100 by the limiting ring 33, the storage tank 100 by the connecting piece 31, and the storage tank 100 by the pressure plate 32. Thus, during the disassembly and assembly of the various structures of the installation mechanism 3 and the disassembly and assembly of the structure of the installation mechanism 3 with the storage tank 100, the temperature measuring mechanism 1 and the installation mechanism 3 can be installed on the storage tank 100 simultaneously, making disassembly and assembly convenient and simple.

[0075] In this embodiment, the temperature control device further includes a controller 4, which is located on the top of the housing 11. The controller 4 is electrically connected to the temperature detector and the temperature regulating mechanism 2, and is used to receive temperature signals and control the opening and closing of the temperature regulating mechanism 2.

[0076] Furthermore, the controller 4 is electrically connected to the exhaust fan 15 to control the opening and closing of the exhaust fan 15.

[0077] An example is provided illustrating the usage process and working principle of the above-mentioned temperature control device:

[0078] The temperature measuring mechanism 1 is placed on top of the storage tank 100, and the inlet pipe 13 and outlet pipe 14 are connected to the storage tank 100, thus forming a circulation path between the storage tank 100, the inlet pipe 13, the housing 11, and the outlet pipe 14. Multiple connectors 31 are connected to the housing 11 of the temperature measuring mechanism 1, and the multiple connectors 31 are spaced apart circumferentially around the storage tank 100. Multiple pressure plates 32 are detachably connected to the outer periphery of the storage tank 100 at circumferential intervals, and each pressure plate 32 fixes a heating wire 21 to the outer periphery of the storage tank 100, thereby achieving the installation of the heating wire 21. Each connector 31 is passed through a corresponding through hole 321 on a pressure plate 32 from top to bottom. Then, the limiting ring 33 is fitted onto the lower end cap 130 of the storage tank 100. After the connector 31 is passed through the inside of the limiting ring 33 from top to bottom, the connector 31 is pulled upward so that it bypasses the limiting ring 33 and extends upward until it is taut. Then, the ring 35 on the connector 31 is hooked onto one of the hooks 34 at a suitable height on the corresponding pressure plate 32 to securely install the structure. When the connector 31 is taut, the bottom of the box 11 is in close contact with the top of the storage tank 100, thereby firmly fixing the box 11.

[0079] After the temperature measuring mechanism 1 and the temperature regulating mechanism 2 are installed, the exhaust fan 15 is started to draw carbon dioxide from the storage tank 100 into the box 11. The carbon dioxide can then flow back into the storage tank 100 through the outlet pipe 14, thereby achieving the purpose of circulating carbon dioxide between the storage tank 100 and the box 11. During the above process, the temperature measuring element 12 detects the temperature signal of the carbon dioxide drawn into the box 11 in real time. When the temperature drops, the controller 4 controls multiple heating wires 21 to start according to the temperature signal. The heating wires 21 heat the outer periphery of the storage tank 100, thereby regulating the temperature of the carbon dioxide inside the storage tank 100 until the temperature is maintained at the required temperature. Then, the controller 4 shuts off the multiple heating wires 21, thereby achieving the purpose of temperature control.

[0080] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects:

[0081] In this application, the housing of the temperature measuring mechanism is connected and fixed to a pressure plate that is detachably connected to the outer periphery of the storage tank through multiple connectors, so that the housing is pressed tightly against the top of the storage tank. Furthermore, since the multiple connectors are arranged at intervals along the circumference of the storage tank, the housing can be circumferentially fixed, thereby achieving a firm fixation of the housing. At the same time, the above design also makes it easy to disassemble the temperature measuring mechanism from the storage tank, making the operation convenient and simple.

[0082] Furthermore, because the storage tank, outlet pipe, casing, and inlet pipe form a circulation path, carbon dioxide in the storage tank can enter the casing for temperature detection by the temperature sensor, thus obtaining the carbon dioxide temperature signal. After temperature detection, the carbon dioxide in the casing can also flow back into the storage tank, thereby achieving the purpose of carbon dioxide circulation between the storage tank and the casing. After temperature detection, when the carbon dioxide temperature drops, the storage tank can be heated by the temperature control mechanism to raise the temperature of the carbon dioxide inside until the temperature is maintained at the required level, thereby achieving the purpose of temperature control.

[0083] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
