However, in practical applications, the working efficiency of thermoelectric core is greatly affected by temperature. In order to improve the working efficiency of thermoelectric core, it is necessary to control its temperature.

[0003] There are two types of temperature control for thermoelectric cores: passive temperature control technology, which mainly dissipates heat or heats through natural convection, radiation and heat conduction; active temperature control technology, which mainly dissipates heat or heats through external energy input, such as air cooling, liquid cooling, heat pipes, phase change materials, etc.

[0004] Since the existing thermoelectric core uses a heat sink to absorb heat, the heat sink is bonded to the outside of the thermoelectric core, which prevents external gas from entering between the heat sink and the thermoelectric core, thereby affecting the heat dissipation of the thermoelectric core and resulting in unsatisfactory heat dissipation effect of the thermoelectric core; therefore, a temperature control device for a thermoelectric core is proposed to address the above problem. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The following is combined with Figure 1 —4 further details of this application,

[0024] The embodiment of the present application discloses a temperature control device for a thermoelectric core, including a thermoelectric core substrate 1; the outer surface of the thermoelectric core substrate 1 is equidistantly connected with heat-conducting columns 2, the heat-conducting columns 2 are used to reverse the heat inside the thermoelectric core substrate 1, and the outer surfaces of a plurality of heat-conducting columns 2 are connected with heat dissipation rings 3, the heat dissipation rings 3 are used to dissipate the heat reversed by the heat-conducting columns 2, and the top edges of the heat dissipation rings 3 are equidistantly embedded with connecting tubes 4, one end of the plurality of connecting tubes 4 is connected with hollow circular rings 5, a guide tube 6 is embedded in the middle of the top of the hollow circular ring 5, a heat dissipation fan 7 is installed at the middle of the top of the guide tube 6 by screws, the input end of the heat dissipation fan 7 is electrically connected to the output end of the external power supply, and is used to drain the gas, and allow the drained gas to enter the outside of the thermoelectric core substrate 1.

[0025] Reference Figure 2 and Figure 4 A positioning groove 11 is provided inside the heat dissipation ring 3 at a position corresponding to one end of the heat-conducting column 2. The positioning groove 11 is used to position and limit the heat-conducting column 2 to prevent the heat-conducting column 2 from shaking. The shape of the heat-conducting column 2 is T-shaped and circular holes 8 are equidistantly provided inside the heat-conducting column 2. The circular holes 8 are used for the flow of gas and the T-shape increases the force range between the heat-conducting column 2 and the thermoelectric core substrate 1.

[0026] Reference Figure 3 and Figure 4 The outer surface of the heat dissipation ring 3 is equidistantly provided with heat dissipation holes 9, which are used for the flow of gas between the heat dissipation ring 3 and the thermoelectric core substrate 1. A one-way diaphragm 10 is bonded to the bottom end of the inner wall of the heat dissipation hole 9 to block the heat dissipation hole 9 and prevent the problem of heat loss along the inside of the heat dissipation hole 9.

[0027] Reference Figure 4 The connecting tube 4 and the heat dissipation ring 3 are connected through the heat dissipation hole 9, which is used for embedding the connecting tube 4 and positioning the connecting tube 4. The outer surface of the connecting tube 4 and the inner wall of the heat dissipation hole 9 fit each other, reducing the gap between the connecting tube 4 and the heat dissipation hole 9.

[0028] Reference Figure 4 The top end of the connecting pipe 4 is equidistantly embedded in the hollow circular ring 5, and a cavity is opened inside the hollow circular ring 5.

[0029] Reference Figure 1 and Figure 2 , heating strips 12 are symmetrically installed on the outer surface of the thermoelectric core substrate 1 at the edges of both sides of the heat-conducting column 2, and the input end of the heating strip 12 is electrically connected to the output end of the external power supply. The heating strip 12 is used to heat the thermoelectric core substrate 1 to prevent the problem of too low surface temperature of the thermoelectric core substrate 1. A temperature sensor 13 is installed on the outer surface of the thermoelectric core substrate 1 between the two heating strips 12. The temperature sensor 13 is used to detect the heat of the thermoelectric core substrate 1 and transmit it to the inside of the controller, and when the temperature transmitted by the temperature sensor 13 is higher than the maximum value predetermined in advance, the cooling fan 7 is controlled to run at this time. When the temperature sensor 13 is lower than the minimum value predetermined in advance, the heating strip 12 starts to run to heat the thermoelectric core substrate 1. A positioning ring 14 is melt-cast and connected at one end of the thermoelectric core substrate 1, and an extrusion rod 15 is clamped inside the positioning ring 14.

[0030] Reference Figure 1 and Figure 2 One end of the heat dissipation ring 3 is located between the inner wall of the positioning ring 14 and the outer surface of the thermoelectric core substrate 1. The heat dissipation ring 3 and the positioning ring 14 are squeezed and fixed to the thermoelectric core substrate 1 by an extrusion rod 15. The heat dissipation ring 3 is placed between the positioning ring 14 and the thermoelectric core substrate 1 and is squeezed by the extrusion rod 15, thereby achieving the purpose of fixing the heat dissipation ring 3.

[0031] Working principle: During the actual use of the device, when the temperature of the thermoelectric core substrate 1 exceeds the preset value, the cooling fan 7 is connected to the power supply and starts to run. When the cooling fan 7 is running, it drives the external gas into the guide tube 6, and enters the hollow circular ring 5 along the guide tube 6, causing the pressure inside the hollow circular ring 5 to increase. When the pressure inside the hollow circular ring 5 increases, the one-way diaphragm 10 is squeezed, so that the one-way diaphragm 10 opens and closes. When the one-way diaphragm 10 opens and closes, the gas enters the outside of the heat-conducting column 2 along the hollow circular ring 5, and It flows along the outside of the heat-conducting column 2 and enters between the thermoelectric core substrate 1 and the heat dissipation ring 3. At this time, the extrusion pressure on the inside of the remaining one-way diaphragm 10 increases, causing the gas to be discharged outward along the one-way diaphragm 10, thereby achieving the purpose of quickly cooling the thermoelectric core substrate 1, preventing the thermoelectric core substrate 1 from being damaged by high temperature, and not hindering the normal heat dissipation of the thermoelectric core substrate 1. At the same time, when the temperature of the thermoelectric core substrate 1 is too low, it can be insulated to reduce its heat dissipation, thereby indirectly reducing the energy and time required for heating.

[0032] When the temperature of the thermoelectric core substrate 1 is lower than a preset value, the heating strip 12 starts to operate and heats the thermoelectric core substrate 1. At the same time, the one-way diaphragm 10 is in a closed state. The heat generated by the heating strip 12 during the heating process remains between the thermoelectric core substrate 1 and the heat dissipation ring 3, resulting in the heat being unable to dissipate quickly, thereby reducing the energy consumption required for heating the heating strip 12 and reducing the time required for heating.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
