[0002] In industrial production and laboratory environments, small or mobile process vessels are widely used in various scenarios, such as chemical reactions, sample handling, and biopharmaceuticals. These vessels typically require precise temperature control to meet specific process requirements. However, in practical applications, the heating and cooling functions of these vessels are often significantly limited due to the inconvenience of access to utilities at the site. Some vessels only provide heating and cannot offer cooling, making it even more difficult to achieve complete control over the heating and cooling processes.
[0003] Currently, to overcome this problem, some equipment is equipped with dedicated temperature control devices, such as integrated heating and cooling temperature control units. These devices, by integrating heating and cooling units, can meet the need for bidirectional temperature regulation to a certain extent. However, existing temperature control devices are usually bulky, complex in structure, and expensive. Furthermore, these devices typically require filling the container's jacket with heat-conducting oil or water, which not only increases the overall weight of the equipment but may also lead to leakage risks, thus affecting the reliability and safety of the equipment's operation.

[0031] The following reference Figures 1 to 3 This application describes a jacketed container according to some embodiments.
[0032] This application provides a jacketed container, such as Figure 1 and Figure 2 As shown, the jacketed container 2 includes an inner sleeve, a jacket 2, a dry heating unit 3, and a thermoelectric cooler 4. The jacket 2 is fitted onto the outside of the inner cylinder 1. The interior of the jacket 2 forms a heating zone and a cooling zone. The dry heating unit 3 is located in the heating zone within the jacket 2 and is laid on the outer wall of the inner cylinder 1 in that zone. When energized, the dry heating unit 3 provides heat to heat the inner cylinder 1 and the medium within it. The thermoelectric cooler 4 is located in the cooling zone within the jacket 2 and is laid on the outer wall of the inner cylinder 1 in that zone. When energized, the thermoelectric cooler 4 provides cooling to cool the inner cylinder 1 and the medium within it. Thus, through the dry heating unit 3 and the thermoelectric cooler 4, the jacketed container 2 possesses both heating and cooling functions without relying on the connection of external utilities or the need for temperature control equipment. This avoids occupying a large space, reduces costs, and eliminates the risk of leakage.
[0033] In this embodiment, preferably, the interior of the jacket 2 is divided into two half-zones along the radial direction of the jacket 2, one half-zone is used as a heating zone and the other half-zone is used as a cooling zone.
[0034] Alternatively, there may be multiple heating and cooling zones, with the multiple heating and cooling zones arranged alternately along the circumference of the jacket 2.
[0035] Alternatively, the interior of jacket 2 is divided into multiple zones along its circumferential direction. Parts of these zones are used as heating zones, and the remainder are used as cooling zones, with the heating and cooling zones alternating. It should be noted that both the heating and cooling zones are concentrated within the effective filling height of the medium inside the cylinder.
[0036] In one embodiment of this application, preferably, the dry heating unit 3 is a thin-film heating element, a conveyor belt heating element, or an electric heating wire heating element, making the dry heating unit 3 a flexible sheet shape so as to fit and conform to the outer wall of the inner cylinder 1 and provide the heating area required for heating the inner cylinder 1. This enables the jacket 2 container to have a heating function, and the realization of the heating function does not depend on the connection of external utility media and temperature control equipment, nor does it require the introduction of high-temperature circulating liquid for heating into the jacket 2.
[0037] In this embodiment, preferably, the dry heating unit 3 is provided with multiple pieces, and the multiple pieces of dry heating unit 3 are respectively laid on the outer side wall of the inner cylinder 1 in the heating area to provide sufficient heating area for the inner cylinder 1, so that the inner cylinder 1 and the medium inside it can be heated to the required temperature and the heating efficiency is guaranteed.
[0038] In this embodiment, preferably, as follows: Figure 2 As shown, a temperature sensor 31 is provided between the dry heating unit 3 and the outer wall of the inner cylinder 1 to monitor the temperature of the inner cylinder 1 in real time. This allows for the control of the start / stop of the dry heating unit 3 and the heating power based on the real-time temperature of the inner cylinder 1, thereby achieving temperature protection for the heating of the inner cylinder 1 and preventing overheating.
[0039] Specifically, the sensing end of the temperature sensor 31 can be directly clamped between the dry heating power supply and the outer wall of the inner cylinder 1; or, a sleeve can be installed on the dry heating unit 3 so that the sensing end of the temperature sensor 31 passes through the sleeve and abuts against the outer wall of the inner cylinder 1, and the temperature sensor 31 can be snapped into the sleeve to fix the temperature sensor 31.
[0040] In this embodiment, preferably, as follows: Figure 2 As shown, the dry heating unit 3 has an insulation material layer 32 laid on the side away from the inner cylinder 1 to prevent heat loss to the environment when the dry heating unit 3 heats the inner cylinder 1, thus ensuring heating efficiency.
[0041] In one embodiment of this application, preferably, as shown below, Figure 2 and Figure 3As shown, the thermoelectric cooler 4 is a solid-state semiconductor refrigeration chip based on the Peltier effect. The thermoelectric cooler 4 has a semiconductor thermopile inside. When the thermoelectric cooler 4 is energized, heat can be transferred from one end of the thermoelectric cooler 4 to the other end, so that the thermoelectric cooler 4 forms a cold end 41 with a lower temperature and a hot end 42 with a higher temperature.
[0042] In this embodiment, the cold end 41 of the thermoelectric cooler 4 is attached to the outer wall of the inner cylinder 1, and the hot end 42 of the thermoelectric cooler 4 is provided with heat dissipation fins 43. Thus, when the thermoelectric cooler 4 is powered on, the heat of the inner cylinder 1 and its internal medium can be transferred to the hot end 42 through the cold end 41 of the thermoelectric cooler 4, and then dissipated through the hot end 42 and the heat dissipation fins 43 provided on the hot end 42, so as to achieve cooling of the inner cylinder 1 and its internal mechanism, so that the jacket 2 container has a cooling function, and the realization of the cooling function does not depend on the access of external public engineering media and temperature control equipment, nor is it necessary to introduce low temperature circulating liquid for cooling into the jacket 2.
[0043] In this embodiment, preferably, there are multiple thermoelectric coolers 4, so that multiple thermoelectric coolers 4 can provide sufficient cooling area for the inner cylinder 1 to cool the inner cylinder 1 and the medium inside it to the required temperature and ensure cooling efficiency.
[0044] In one embodiment of this application, preferably, a thermally conductive material layer is coated on the outer wall of the inner cylinder 1; for example, the thermally conductive material layer is a layer of thermally conductive silicone grease coated on the outer wall of the inner cylinder 1.
[0045] Preferably, the outer wall of the inner cylinder 1 that contacts the dry heating unit 3 is coated with a heat-conducting material layer, so that the dry heating unit 3 contacts the outer wall of the inner cylinder 1 through the heat-conducting material layer. This ensures the tightness of the fit between the dry heating unit 3 and the outer wall of the inner cylinder 1 when the dry heating unit 3 is used to heat the inner cylinder 1 and its internal medium, and effectively improves the heat transfer efficiency.
[0046] Preferably, the outer wall of the inner cylinder 1 that contacts the cold end 41 of the thermoelectric cooler 4 is coated with a thermally conductive material layer, so that the cold end 41 of the thermoelectric cooler 4 contacts the outer wall of the inner cylinder 1 through the thermally conductive material layer. This ensures the tightness of the contact between the cold end 41 of the thermoelectric cooler 4 and the outer wall of the inner cylinder 1 when the thermoelectric cooler 4 is used to cool the inner cylinder 1 and its internal medium, and effectively improves the heat transfer efficiency.
[0047] Preferably, a thermally conductive material layer is coated on the surface of the hot end 42 of the thermoelectric cooler 4, so that the heat dissipation fins 43 are attached to the thermally conductive material layer of the hot end 42 of the thermoelectric cooler 4, thereby improving the heat transfer efficiency from the hot end 42 of the thermoelectric cooler 4 to the heat dissipation fins 43 to a certain extent, and thus improving the heat dissipation efficiency of the hot end 42 of the thermoelectric cooler 4.
[0048] In one embodiment of this application, preferably, as shown below, Figure 2 As shown, the jacket 2 is also equipped with a fixing member 23, which is fixed to one of the inner side wall of the jacket 2 and the outer side wall of the inner cylinder 1. Cable ties are provided on the dry heating unit 3, the thermoelectric cooler 4, the insulation material layer 32, and the heat dissipation fins 43, and are secured to the fixing member 23 by the cable ties. This ensures the installation stability of the dry heating unit 3, the thermoelectric cooler 4, the insulation material layer 32, and the heat dissipation fins 43 within the jacket 2, allowing them to be stably fixed in the required positions, so that the jacket 2 container has stable heating and cooling functions.
[0049] In one embodiment of this application, preferably, the jacket 2 is provided with an air inlet 21 and an air outlet 22 connecting the inside and outside of the jacket 2, wherein the air inlet 21 is located at the bottom of the jacket 2 and the air outlet 22 is located at the top of the jacket 2; the air inlet 21 can supply cooling air into the jacket 2. For example, if there is a fan on site, the air inlet 21 can be connected to the fan's air outlet 22 to continuously supply air into the jacket 2, or if there is a compressed air supply pipe in the site utility, the air inlet 21 can also be connected to the compressed air supply pipe. This replaces the hot air in the jacket 2, promoting heat dissipation from the hot end 42 and the heat dissipation fins 43 of the thermoelectric cooler 4.
[0050] In this embodiment, preferably, the jacket 2 is provided with a separator to separate the heating area and the cooling area within the jacket 2. The air inlet 21 and the air outlet 22 are both connected to the jacket 2 of the cooling area to effectively sweep the air in the jacket 2 of the cooling area.
[0051] In one embodiment of this application, preferably, the jacket 2 container further includes a controller; the jacket 2 is provided with a cable outlet communicating with the inside and outside of the jacket 2, and the cables of the dry heating unit 3, the temperature sensor 31 and the thermoelectric cooler 4 all extend out of the jacket 2 through the cable outlet and communicate with the controller so as to control the start and stop of the dry heating unit 3 and the thermoelectric cooler 4, as well as the working power, through the controller.
[0052] Preferably, the outlet is located at the bottom of the jacket 2 to avoid the complex pipeline arrangement at the top of the jacket 2 container.
[0053] In one embodiment of this application, preferably, the upper end of the jacket 2 is open and closed by a detachable top cover; for example, the top cover is fixed to the upper end of the jacket 2 by a clamp, flange, or other detachable means. This facilitates the inspection and maintenance of the various components inside the jacket 2.
[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
