[0019] The heater of the exemplary embodiment of the present application is described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations may complement or be combined with each other.

[0020] According to a specific embodiment of the heater of the present application, Figures 1 to 3 As shown, the heater includes a housing 1, a guide rod 2, a first connection part 3 and a second connection part 4, one of which is located on the peripheral side of the guide rod 2, and the other of which is located on the housing 1. Perpendicular to the length direction of the guide rod 2, around the peripheral side of the guide rod 2, the first connection part 3 is at least partially located on one side of the second connection part 4, and the first connection part 3 is also at least partially located on the other side of the second connection part 4. The first connection part 3 and the second connection part 4 are limitedly connected so that the housing 1 can limit the rotation of the guide rod 2 to a certain extent, so that the heating effect of the heater is better. Among them, the direction perpendicular to the length direction of the guide rod 2 and around the peripheral side of the guide rod 2 is the same as the direction along the circumference of the guide rod 2.

[0021] In other possible embodiments, a first plane is defined, the first plane is perpendicular to the length direction of the flow guide rod 2, the first connection portion 3 is at least partially located in the first plane, and the second connection portion 4 is at least partially located in the first plane. In the first plane and in the circumferential direction of the flow guide rod 2, the first connection portion 3 is at least partially located on one side of the second connection portion 4, and the first connection portion 3 is also at least partially located on the other side of the second connection portion 4. The first connection portion 3 and the second connection portion 4 are limitedly connected, so that the box body 1 can limit the rotation of the flow guide rod to a certain extent, so that the heating effect of the heater is better.

[0022] like Figures 1 to 3As shown, in this embodiment, the heater also includes a heating tube 5 and a heating component 6. Both ends of the heating tube 5 in the axial direction are sealed and connected to the box body 1. The guide rod 2 is located in the tube cavity of the heating tube 5, and the tube cavity of the heating tube 5 is connected to the inner cavity of the box body 1. The heating component 6 is attached to the circumference of the heating tube 5. The heating component 6 can be a film heating element. The film heating element has the advantages of good heating performance, large heating area, uniform heating and low cost. The film heating element includes an insulating layer and a thin film heating layer sandwiched between two insulating layers. The thin film heating layer is electrically connected to an external power supply so that the thin film heating layer can heat the heating tube 5, and then heat the working medium flowing through the tube cavity of the heating tube 5 by heat conduction. As an optional embodiment, the film heating element can be a thin film heating element or a thick film heating element. The thin film heating element has a small thermal resistance, high heating performance and heat conduction efficiency, and the thick film heating element has high mechanical strength and a long service life. When a thin film heating element is used, the thin film heating element can be made by a thermal spraying process. When a thick film heating element is used, the thick film heating element can be made by screen printing or sintering.

[0023] Among them, since the heating component 6 heats the tube wall of the heating tube 5, the closer the working medium is to the inner wall of the tube cavity of the heating tube 5, the better the heating effect is. The guide rod 2 is located in the tube cavity of the heating tube 5, and the guide rod 2 is located on the axis of the heating tube 5, that is, the center line position of the heating tube 5, so that the center position of the heating tube 5 cannot flow the working medium due to the obstruction of the guide rod 2 structure. The working medium flows around the guide rod 2, so that the fluid is closer to the tube wall, thereby improving the heating effect of the heating component 6. The guide rod 2 includes a rod portion 21 and a guide structure 22. The rod portion 21 is a slender rod-shaped structure, and the length direction of the guide rod 2 is the same as the length direction of the rod portion 21. The guide structure 22 is located on the circumference of the rod portion 21, and the guide structure 22 is a spiral structure. The guide structure 22 and the rod portion 21 are an integrated structure. The working medium flows around the circumference of the rod 21 under the guidance of the flow guide structure 22, increasing the contact area between the working medium and the inner wall of the heating tube 5, thereby improving the heat exchange efficiency between the working medium and the wall of the heating tube 5 and further improving the heating effect.

[0024] like Figure 2 and Figure 3As shown, in this embodiment, the first connection part 3 is located on the peripheral side of the guide rod 2, and the second connection part 4 is located on the box body 1. The guide rod 2 includes a first end 23 and a second end 24, the first end 23 is located at one end of the length direction of the rod part 21, and the second end 24 is located at the other end of the length direction of the rod part 21. The box body 1 and the first end 23 are sealed and connected, and the box body 1 includes a first wall 11, and the first wall 11 is a box wall connecting the box body 1 and the first end 23. The first connection part 3 includes a first connection structure 31 and a second connection structure 32, and the guide rod 2, the first connection structure 31 and the second connection structure 32 are an integral structure. The first connection structure 31 includes a first end 311 and a second end 312, and the first end 311 of the first connection structure 31 is connected to the first end 23. The first wall 11 has a first through hole 111, and the first connection structure 31 is at least partially located in the first through hole 111. Optionally, according to the specific structure of the guide rod 2, the guide rod 2 may also be at least partially located in the first through hole 111, or the guide rod 2 and the first connection structure 31 may both be at least partially located in the first through hole 111. The second end 312 of the first connection structure 31 is connected to the second connection structure 32, and the second connection structure 32 is located in the inner cavity of the box body 1. The second connection structure 32 is a structure in which the second end 312 of the first connection structure 31 protrudes to a side away from the axis of the first through hole 111, and the second connection structure 32 is connected to the first wall 11. The number of the first connection parts 3 is at least two, and at least two first connection parts 3 are arranged at intervals along the circumferential direction of the guide rod 2. The second connection part 4 is a protruding structure located in the box body 1, and the second connection part 4 is at least partially located between two adjacent first connection parts 3. The structures of the first connection part 3 and the second connection part 4 of this structure are relatively simple, and the first connection part 3 can limit the rotation of the guide rod 2 to a certain extent, and can also limit the movement of the guide rod 2 along the length direction of the guide rod 2, which is conducive to further simplifying the structure of the heater. Among them, the second connection part 4 can be located between two adjacent first connection structures 31, or between two adjacent second connection structures 32. At the same time, the second connection part 4 is located at at least one of the end of the first wall 11 close to the inner cavity of the box body 1, the end of the first wall 11 away from the inner cavity of the box body 1, and the end of the inner hole wall of the first through hole 111 close to the axis of the first through hole 111. Optionally, the second connection part 4 can be located at the end of the first wall 11 close to the inner cavity of the box body 1; the second connection part 4 can also be located at the end of the first wall 11 away from the inner cavity of the box body 1; the second connection part 4 can also be a protruding structure of the inner hole wall of the first through hole 111 protruding to the side close to the axis of the first through hole 111, that is, the second connection part 4 is located at the end of the inner hole wall of the first through hole 111 close to the axis of the first through hole 111.

[0025] In this embodiment, the first connecting structure 31 is an elastic part. When the guide rod 2 and the box body 1 of the heater are assembled, the heating tube 5 and the box body 1 are first connected by welding or the like, and then the guide rod 2 is placed in the heating tube 5. When the second connecting structure 32 contacts the first wall 11, the first connecting structure 31 produces elastic deformation, so that the second connecting structure 32 can pass through the first through hole 111; after the second connecting structure 32 passes through the first through hole 111, the elastic deformation of the first connecting structure 31 is restored, so that the second connecting structure 32 is located in the inner cavity of the box body 1 and connected to the first wall 11.

[0026] like Figure 2 and Figure 3 As shown, further, the second connection structure 32 includes a first guide surface 321, and the first guide surface 321 is located at an end of the second connection structure 32 away from the first wall 11. From the end of the second connection structure 32 close to the first wall 11 to the end of the second connection structure 32 away from the first wall 11, the distance between the first guide surface 321 and the axis of the first through hole 111 gradually decreases. When the box body 1 of the guide rod 2 of the heater is assembled, the first guide surface 321 can guide the first connection structure 31 to produce elastic deformation, thereby improving the convenience of assembling the heater.

[0027] like Figure 4 As shown, further, when the second connecting portion 4 is located at the end of the first wall 11 away from the inner cavity of the box body 1, the second connecting portion 4 includes a first part 41 and a second part 42, the second part 42 is located at the end of the second connecting portion 2 close to the first wall 11, and the first part 41 is located on the side of the second part 42 away from the first wall 11. From the end of the first part 41 close to the first wall 11 to the end of the first part 41 away from the first wall, the cross section of the first part 41 perpendicular to the length direction of the guide rod 2 gradually decreases. When the guide rod 2 and the box body 1 of the heater are assembled, the first part 41 can guide the first connecting portion 3 to move to a more accurate matching position, thereby improving the accuracy and convenience of the heater assembly. Among them, the first part 41 can be a conical structure, a truncated cone structure, a spherical structure or a prismatic structure. The cross section of the second part 42 perpendicular to the length direction of the guide rod 2 remains unchanged, so that the contact area at the connection between the second part 42 and the second connecting portion 3 is larger, which can improve the stability of the connection between the second part 42 and the second connecting portion 3.

[0028] like Figure 5As shown, in some other possible embodiments, the first connection part 3 is located at the box body 1, and the second connection part 4 is located at the circumferential side of the guide rod 2.
