[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0034] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0035] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0036] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0037] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "above" and "above" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0039] In the related art, a high temperature device has a containing cavity, which can be used to contain items to be heated. The high temperature device can heat the items to be heated in the high temperature device by means of resistance wire heating or heating rod heating. During the cooling process of the containing cavity, the cavity cover of the containing cavity can be opened to cool the containing cavity by natural wind.

[0040] However, the efficiency of natural wind cooling is low, resulting in a long cooling time for the accommodating chamber (for example, it usually takes several hours, for example, more than 5 hours, and for some ultra-high temperature scenarios, it may take 20 hours to wait), which leads to low efficiency of high temperature equipment use, low reuse rate of high temperature equipment, waste of equipment resources, and reduced efficiency of testing and production. In addition, when the accommodating chamber is in the period of opening the cover at high temperature, a dedicated person is required to be on duty to prevent accidents, which wastes human resources, and there is a risk of scalding and fire when opening the cover of the high temperature chamber. In particular, for some scenes where the items to be heated need to be subjected to multiple high-temperature treatments and need to be cooled and weighed, the cooling time will be longer and the efficiency of high temperature equipment will be lower. In addition, for special samples, it may be necessary to heat and cool them down multiple times under the protection of inert gas, making it impossible to open the cover for cooling, and the accommodating chamber can only wait for cooling naturally, which will further extend the cooling time and further reduce the efficiency of high temperature equipment use.

[0041] In order to solve the above problems, an embodiment of the present application provides a temperature control device, in which a fluid channel is formed through at least a portion of the first accommodating chamber between the first shell and the second shell, and a fluid can be passed into the fluid channel to take away the heat of the first shell and the second shell to cool the first shell and the second shell, thereby accelerating the cooling speed of the accommodating chamber, shortening the cooling time of the accommodating chamber, improving the use efficiency of the temperature control device, saving equipment resources, and improving the efficiency of testing and production. In addition, there is no need to open the accommodating chamber, so there is no need for a dedicated person on duty, thereby saving human resources and reducing the risk of burns and fire caused by opening the accommodating chamber at high temperatures. Secondly, since there is no need to open the accommodating chamber, the temperature control device can also be used in processing scenarios of special samples that require heating and cooling under the protection of inert gas, thereby broadening the scope of application of the temperature control device.

[0042] The following will be combined Figure 1 and Figure 2 The temperature control device 100 provided in the embodiment of the present application is described.

[0043] See also Figure 1 The embodiment of the present application provides a temperature control device 100, which may include a first shell 110 and a second shell 120. The first shell 110 may be provided with a first accommodating chamber, and the second shell 120 may be provided with a second accommodating chamber 122. The first shell 110 may protect the structural parts located in the first accommodating chamber, and the second accommodating chamber 122 may be used to accommodate items to be heated (e.g., samples). The second shell 120 may be located in the first accommodating chamber, and at least part of the first accommodating chamber between the first shell 110 and the second shell 120 may form a fluid channel 130, and a fluid may flow into the fluid channel 130, and the heat of the first shell 110 and the second shell 120 may be taken away by the fluid to cool the first shell 110 and the second shell 120, so as to accelerate the cooling speed of the second accommodating chamber 122, shorten the cooling time of the second accommodating chamber 122, improve the use efficiency of the temperature control device 100, save equipment resources, and improve the efficiency of testing and production. In addition, since the second accommodating chamber 122 does not need to be opened, there is no need for a dedicated person to be on duty, thereby saving human resources and reducing the risk of burns and fire caused by the second accommodating chamber 122 being opened at high temperatures. Secondly, since the second accommodating chamber 122 does not need to be opened, the temperature control device 100 can be used in processing scenarios where samples require inert gas protection, thereby broadening the scope of application of the temperature control device 100. In this scenario, the use efficiency of the temperature control device 100 can also be improved, saving equipment resources and improving the efficiency of testing and production.

[0044] The embodiment of the present application adopts a double-layer structure of the first shell 110 and the second shell 120 (for example, the temperature control device 100 can be a full double-layer structure, or can also be a partial double-layer structure), and a fluid channel 130 is reserved between the first shell 110 and the second shell 120. It is equivalent to that the first shell 110 and the second shell 120 are connected to each other to form a hollow structure, and the hollow structure is planned with a fluid channel 130. When cooling, a fluid can be passed into the fluid channel 130. Since at least part of the first accommodating cavity between the first shell 110 and the second shell 120 can form a fluid channel 130, the fluid in the fluid channel 130 can be in direct contact with the first shell 110 and the second shell 120. The heat on the first shell 110 and the second shell 120 is directly transferred to the fluid, so that the fluid has a high cooling efficiency for the first shell 110 and the second shell 120, thereby achieving a rapid cooling effect. The cooling efficiency of the temperature control device 100 is improved, the reuse rate of the temperature control device 100 is improved, the test efficiency is improved, and the risk of fire and scalding is reduced.

[0045] Exemplarily, the first shell 110 and the second shell 120 may be connected by welding, threading or other methods.

[0046] Exemplarily, the shape of the first shell 110 and the second shell 120 may be cylindrical, or other cylindrical shapes, or other shapes such as a cube and a polyhedron.

[0047] For example, the first shell 110 and the second shell 120 may be placed in different ways such as vertical, horizontal or inclined.

[0048] For example, see Figure 1 The first housing 110 may be provided with an inlet 113 and an outlet 114, both of which may be communicated with the fluid channel 130, and the inlet 113 may be used to communicate with a fluid source, the fluid source may be used to provide a fluid, and the fluid source may pass the fluid into the fluid channel 130 through the inlet 113. In addition, the outlet 114 may also be used to communicate with the fluid source, so as to facilitate the circulation of the fluid between the fluid source and the fluid channel 130. The fluid channel 130 is communicated with the inlet 113 and the outlet 114, so that the second accommodating chamber 122 becomes a space that can meet the experimental conditions.

[0049] For example, the fluid may be a gas, a liquid or the like.

[0050] In some embodiments, see Figure 1, the temperature control device 100 may include an electromagnetic coil 140, and the electromagnetic coil 140 may be located on the outside of the first shell 110, that is, the electromagnetic coil 140 may be located on the side of the first shell 110 away from the second shell 120, thereby reducing the difficulty of installation and maintenance of the electromagnetic coil 140. Electric current can be passed through the electromagnetic coil 140 to form an electromagnetic induction coil, and electromagnetic induction can be formed on the second shell 120 to quickly heat the second shell 120, thereby quickly heating the accommodating cavity. In addition, in the related art, heating by resistance wire heating or heating rod heating has problems such as high local temperature and uneven temperature field. The embodiment of the present application adopts electromagnetic heating, and the heating field is the heating of the entire internal surface, and the temperature field is more uniform, which can alleviate the problems of high local temperature and uneven temperature field.

[0051] Exemplarily, the material of the first shell 110 may include a non-magnetic material, and the material of the second shell 120 may include a magnetic material. Alternatively, the material of the first shell 110 and the material of the second shell 120 may both be magnetic materials, and the magnetism of the first shell 110 may be less than that of the second shell 120, that is, the first shell 110 may use a weak magnetic material, and the second shell 120 may use a magnetic material. In this way, the electromagnetic coil 140 can mainly act on the second shell 120, and the heat generated by the second shell 120 is relatively large, which is conducive to improving the heating efficiency of the electromagnetic coil 140 on the second accommodating cavity 122 in the second shell 120.

[0052] In some embodiments, see Figure 1 The electromagnetic coil 140 may include a first electromagnetic coil 141, and the first electromagnetic coil 141 may be disposed around the outer circumference of the first housing 110. For example, the first electromagnetic coil 141 may be a spiral coil.

[0053] In some embodiments, see Figure 1 , the electromagnetic coil 140 may include a second electromagnetic coil 142, and the second electromagnetic coil 142 may be disposed on a side of the top wall of the first housing 110 away from the second housing 120. And / or, the second electromagnetic coil 142 may be disposed on a side of the bottom wall of the first housing 110 away from the second housing 120. The second electromagnetic coil 142 may be disposed on at least one of a side of the top wall of the first housing 110 away from the second housing 120 and a side of the bottom wall of the first housing 110 away from the second housing 120.

[0054] It is understandable that the electromagnetic coil 140 may include at least one of a first electromagnetic coil 141 and a second electromagnetic coil 142. In an embodiment where the first electromagnetic coil 141 and the second electromagnetic coil 142 are provided at the same time, the first electromagnetic coil 141 and the second electromagnetic coil 142 may act together on the second shell 120, thereby accelerating the temperature rise speed of the second shell 120 and improving the temperature rise efficiency of the second shell 120 and the second accommodating cavity 122.

[0055] Exemplarily, an auxiliary fluid channel may be provided in the electromagnetic coil 140, and the auxiliary fluid channel may be in the same extension direction as the electromagnetic coil 140, and auxiliary inlets and auxiliary outlets may be provided at both ends of the extension direction of the electromagnetic coil 140, respectively, and the two ends of the auxiliary fluid channel may be connected to the auxiliary inlet and the auxiliary outlet, respectively. For example, the electromagnetic coil 140 may be wound using a hollow conductive coil, and the coil is a hollow structure to form an auxiliary fluid channel in the electromagnetic coil 140, and auxiliary outlets and auxiliary inlets may be provided at both ends of the coil, respectively. When cooling the second accommodating chamber 122, fluid may be introduced into the auxiliary fluid channel to quickly cool the electromagnetic coil 140, thereby facilitating rapid cooling of the entire temperature control device 100. Of course, during the cooling process, the auxiliary fluid channel of the electromagnetic coil 140 may also be cooled naturally without introducing fluid.

[0056] In some embodiments, see Figure 2 The temperature control device 100 may include an insulating member 150 . The insulating member 150 may be located between the electromagnetic coil 140 and the first shell 110 . The insulating member 150 may electrically isolate the electromagnetic coil 140 from the first shell 110 , and may also support the electromagnetic coil 140 .

[0057] It is understandable that the temperature control device 100 may not be provided with the insulating member 150 .

[0058] In some embodiments, see Figure 1 The temperature control device 100 may include a thermal insulation layer 160. The thermal insulation layer 160 may be located on the side of the electromagnetic coil 140 away from the first shell 110. The thermal insulation layer 160 is an externally coated or filled thermal insulation material to achieve the purpose of heat insulation. The thermal insulation layer 160 is beneficial to reduce the impact of the external environment on the temperature of the second shell 120, the second accommodating cavity 122, etc., thereby improving the temperature stability and controllability of the second accommodating cavity 122.

[0059] In some embodiments, see Figure 1The fluid channel 130 may include a first fluid channel 131, the side wall of the first shell 110 and the side wall of the second shell 120 may be spaced apart, and the first accommodation cavity between the side wall of the first shell 110 and the side wall of the second shell 120 may form the first fluid channel 131. In this way, when the fluid is passed into the first fluid channel 131, the side wall of the first shell 110 and the side wall of the second shell 120 may be cooled, thereby quickly cooling the second accommodation cavity 122.

[0060] In some embodiments, see Figure 1 The fluid channel 130 may include a second fluid channel 132. The top wall of the first shell 110 and the top wall of the second shell 120 may be spaced apart. The first accommodating cavity between the top wall of the first shell 110 and the top wall of the second shell 120 may form the second fluid channel 132 (i.e. Figure 1 In this way, when the fluid is passed into the second fluid channel 132, the top wall of the first shell 110 and the top wall of the second shell 120 can be cooled, thereby quickly cooling the second accommodation cavity 122. And / or, the bottom wall of the first shell 110 and the bottom wall of the second shell 120 can be spaced apart, and the first accommodation cavity between the bottom wall of the first shell 110 and the bottom wall of the second shell 120 can form the second fluid channel 132 (i.e. Figure 1 Thus, the bottom wall of the first shell 110 and the bottom wall of the second shell 120 can be cooled by passing the fluid into the second fluid channel 132, thereby quickly cooling the second accommodating cavity 122.

[0061] Among them, at least one of the first accommodating cavity between the top wall of the first shell 110 and the top wall of the second shell 120, and the first accommodating cavity between the bottom wall of the first shell 110 and the bottom wall of the second shell 120 can form the second fluid channel 132. In the embodiment where the first accommodating cavity between the top wall of the first shell 110 and the top wall of the second shell 120, and the first accommodating cavity between the bottom wall of the first shell 110 and the bottom wall of the second shell 120 both form the second fluid channel 132, the coverage range of the second fluid channel 132 is wider, which can increase the cooling speed of the second fluid channel 132, thereby improving the cooling efficiency of the second fluid channel 132. Among them, Figure 1 and Figure 2 The dashed arrows in show the flow direction of the fluid in the first fluid channel 131 and the second fluid channel 132 .

[0062] In some embodiments, the first fluid channel 131 and the second fluid channel 132 can be isolated from each other, so that the first fluid channel 131 and the second fluid channel 132 can work independently of each other. When one of the first fluid channel 131 and the second fluid channel 132 fails to work, the other can continue to work, thereby improving the availability of the fluid channel 130. In addition, since the fluid channel 130 is divided, the flow path of the fluid in the fluid channel 130 is more controllable. Exemplarily, the inlet 113 may include a first inlet 1131 and a second inlet 1132, and the outlet 114 may include a first outlet 1141 and a second outlet 1142. The first inlet 1131 and the first outlet 1141 may both be connected to the first fluid channel 131, and the first inlet 1131 may be connected to a fluid source, so that the fluid is introduced into the first fluid channel 131 through the first inlet 1131. Of course, the first outlet 1141 may be connected to a fluid source, so that the fluid circulates in the fluid source and the first fluid channel 131. The second inlet 1132 and the second outlet 1142 can both be connected to the second fluid channel 132, and the second inlet 1132 can be connected to the fluid source, so that the fluid is introduced into the second fluid channel 132 through the second inlet 1132. Of course, the second outlet 1142 can be connected to the fluid source, so that the fluid circulates in the fluid source and the second fluid channel 132.

[0063] In some embodiments, the first fluid channel 131 and the second fluid channel 132 can be interconnected, so that the temperature uniformity of the fluid in the first fluid channel 131 and the second fluid channel 132 is better, so that the cooling uniformity of each part of the second accommodating chamber 122 is better, for example, the first fluid channel 131 and the second fluid channel 132 can form a complete fluid channel 130. Exemplarily, the inlet 113 can be connected to one of the first fluid channel 131 and the second fluid channel 132, so that the fluid is introduced into the fluid channel 130 through the inlet 113, and the outlet 114 can be connected to the other of the first fluid channel 131 and the second fluid channel 132. At this time, the first fluid channel 131 and the second fluid channel 132 can share the inlet 113 and the outlet 114, so that the structure of the temperature control device 100 can be simplified and the production cost can be reduced. Of course, the first fluid channel 131 and the second fluid channel 132 may not share the inlet 113 and the outlet 114. By setting more inlets 113 and outlets 114, the flow efficiency of the fluid can be improved.

[0064] In some embodiments, see Figure 1The temperature control device 100 may further include a first sealing member 171. The side wall of the first shell 110 and the side wall of the second shell 120 may be annular, and the side wall of the first shell 110 is sleeved on the outer periphery of the side wall of the second shell 120. In this case, the first fluid channel 131 may be annular. The first fluid channel 131 may be provided with channel openings at both ends along the direction from the top wall to the bottom wall of the first shell 110 (i.e., direction A in the figure). The first sealing member 171 may be covered on the channel opening, so as to achieve connection and sealing between the side wall of the first shell 110 and the side wall of the second shell 120. There may be two first seals 171, one of which may be located between the side wall of the second shell 120 and the top wall of the second shell 120, and between the side wall of the first shell 110 and the top wall of the first shell 110, and the other first seal 171 may be located between the side wall of the second shell 120 and the bottom wall of the second shell 120, and between the side wall of the first shell 110 and the bottom wall of the first shell 110. At this time, the side wall of the first shell 110 and the side wall of the second shell 120 may both be located between the two first seals 171.

[0065] Among them, see Figure 2 The side walls, top wall and bottom wall of the first shell 110 may be a first shell side wall 116, a first shell top wall 115 and a first shell bottom wall 117, and the side walls, top wall and bottom wall of the second shell 120 may be a second shell side wall 124, a second shell top wall 123 and a second shell bottom wall 125.

[0066] In some embodiments, see Figure 2 , the first housing 110 may include a second seal 112, and the second seal 112 may be located on both sides of the side wall of the first housing 110 along the direction from the top wall to the bottom wall of the first housing 110. For example, the second seal 112 may be located on the side of the first seal 171 away from the side wall of the first housing 110 and the side wall of the second housing 120. The second seal 112 may be arranged around the outer periphery of the top wall of the first housing 110 and the top wall of the second housing 120, so as to achieve the connection and sealing between the top wall of the first housing 110 and the top wall of the second housing 120. And / or, the second seal 112 may be arranged around the outer periphery of the bottom wall of the first housing 110 and the bottom wall of the second housing 120, so as to achieve the connection and sealing between the bottom wall of the first housing 110 and the bottom wall of the second housing 120.

[0067] Exemplarily, the first seal 171 and the second seal 112 may be connected, for example, the first seal 171 and the second seal 112 may be an integral structure, thereby simplifying the assembly process of the first seal 171 and the second seal 112. In an embodiment in which a first inlet 1131 and a first outlet 1141 are provided, at least one of the first inlet 1131 and the first outlet 1141 may be provided on the side wall of the first housing 110. In an embodiment in which a second inlet 1132 and a second outlet 1142 are provided, at least one of the second inlet 1132 and the second outlet 1142 may be provided on the second seal 112.

[0068] Exemplarily, the working process of the temperature control device 100 can be: when the second accommodating chamber 122 needs to be heated, the electromagnetic coil 140 is energized. Since the second shell 120 is made of magnetic material, when the electromagnetic coil 140 is supplied with alternating current, electromagnetic induction heating will be formed inside the second shell 120, and the second shell 120 can be quickly heated up to achieve the purpose of quickly heating the second accommodating chamber 122, and the thermal insulation layer 160 plays the role of isolation and protection. When the second accommodating chamber 122 needs to be cooled down, the electromagnetic coil 140 is stopped from being energized, and a fluid is introduced from the inlet 113. The fluid flows through the fluid channel 130, taking away the heat of the second shell 120 and the first shell 110, and the heat of the second accommodating chamber 122 is also conducted away by the second shell 120, so as to achieve the purpose of rapid cooling.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
