[0022] The specific implementation manner of the utility model will be described below in combination with the drawings and examples:

[0023] It should be noted that the structure, proportion, size and the like shown in the drawings of the present application are only used to cooperate with the content disclosed in the present application, so that those skilled in the art can understand and read, and are not used to limit the implementation of the present application.

The change or adjustment of the relative relationship is also considered as the implementation of the present application without substantial change of technical content.

[0025] According to the embodiment of the present application, a heating temperature control device is provided, please refer to Figure 1 , comprising: a heating medium, a power mechanism 1, a control system, a shunt structure 2 capable of adjusting the flow of the heating medium, and a heater 3 having a containing space 32, one end of the shunt structure 2 is connected with the outlet 11 of the power mechanism, the other end of the shunt structure 2 is connected with the inlet 31 of the containing space, the heating medium is conveyed by the power mechanism 1 to the containing space 32 of the heater 3 through the shunt structure 2, the control system comprises a detection structure for detecting the temperature of the heating medium in the containing space 32 and a first flow control module for controlling the flow of the heating medium in the shunt structure 2, and the detection structure is signal connected with the first flow control module. Through the cooperation of the control system, the power mechanism 1 and the shunt structure 2, the heating temperature can be quickly adjusted without replacing the heating medium, the temperature control process is simplified, and the temperature control rate is improved. When the detection structure detects that the temperature of the heating medium in the containing space 32 exceeds a certain set temperature, the first flow control module will regulate the shunt structure 2, and the flow of the heating medium entering the containing space 32 will increase to quickly adjust the temperature in the heater. On the contrary, when the detection structure detects that the temperature of the heating medium in the containing space 32 does not reach a certain set temperature, the first flow control module will also regulate the shunt structure 2, and the flow of the heating medium entering the containing space 32 will decrease to quickly adjust the temperature in the heater 3. Among them, the power mechanism 1 provides power to send the heating medium to the containing space 32 of the heater 3 through the shunt structure 2. The detection structure of the control module detects the temperature of the heating medium in the containing space 32, so that the first flow control module adjusts the flow of the heating medium in the shunt structure 2 to provide stable and adjustable heat supply.

[0026] The control system further comprises a second flow control module for controlling the flow of the heating medium delivered by the power mechanism 1, and the detection structure is in signal connection with the second flow control module. Further, the application can also achieve temperature regulation by adjusting the delivery rate of the heating medium by the power mechanism 1. When the detection structure detects that the temperature of the heating medium in the containing space 32 exceeds a certain set temperature, the second flow control module will regulate the delivery rate of the heating medium by the power mechanism 1, and the flow of the heating medium into the containing space 32 will be increased to quickly adjust the temperature in the heater 3. Conversely, when the detection structure detects that the temperature of the heating medium in the containing space 32 does not reach a certain set temperature, the second flow control module will also regulate the delivery rate of the heating medium by the power mechanism 1, and the flow of the heating medium into the containing space 32 will be reduced to quickly adjust the temperature in the heater 3. The first flow control module and the second flow control module can work simultaneously or alternatively.

[0027] The power mechanism 1 is a blower or a turbofan. When the power mechanism 1 is a blower or a turbofan, the heating medium is the gas discharged by the blower or the turbofan. At this time, no additional heating medium is needed.

[0028] When the power mechanism 1 is a blower, the heating medium is water, silicone oil or paraffin oil. When the power mechanism 1 is a blower, the heating medium can also be a liquid such as water, silicone oil or paraffin oil.

[0030] The flow distribution structure 2 is a flow distributor, which comprises a flow distributor body provided with a liquid inlet pipe 21 and a plurality of branch capillary tubes 23, and the plurality of branch capillary tubes 23 are in communication with the liquid inlet pipe 21. The liquid inlet pipe 21 is connected to the outlet 11 of the power mechanism.

[0031] As shown in Figure 2 The first flow control module comprises a flow distribution adjustment mechanism 22 arranged in the flow distributor body at the flow passage of the branch capillary tubes 23. The first flow control module realizes flow regulation of the flow distributor through the flow distribution adjustment mechanism 22.

[0032] The control system further comprises a third control module for controlling the heating power of the heater 3, and the detection structure is signal connected with the third control module. When the detection structure detects that the temperature of the heating medium in the accommodation space 32 exceeds a certain set temperature, the third control module adjusts the power of the heater 3 to quickly adjust the temperature in the heater 3. Conversely, when the detection structure detects that the temperature of the heating medium in the accommodation space 32 does not reach a certain set temperature, the third control module also adjusts the heating power of the heater 3 to quickly adjust the temperature in the heater 3.

[0033] Specifically, the first flow control module, the second flow control module and the third control module can work simultaneously or independently.

[0034] The heater 3 can be a tubular heat exchanger, the pipeline for accommodating the heating medium is the accommodation space 32, the heating medium enters from the inlet 31 of the accommodation space, exchanges heat with the material, and then flows out from the outlet 33 of the accommodation space, the material enters from the material inlet 35 and flows out from the material outlet 34. Specifically, the heating medium can return to the power mechanism 1 after flowing out from the outlet 33 of the accommodation space or can flow out to be collected.
