[0015] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0016] Combination Figure 1-3 As shown, a flat thick film heating core includes a middle shell 1 and a thick film heating plate 2. A groove 3 is provided on one side of the middle shell 1, and the thick film heating plate 2 is sealed and installed at the end of the groove 3 so that a water chamber is formed inside the groove 3. One end of the middle shell 1 is also provided with an inlet 5 and an outlet 6 that are respectively connected to the tank body 3. The tank body 3 is also provided with two guide channels 7 corresponding to the inlet 5 and the outlet 6 respectively. The two guide channels 7 form an elongated flow channel to avoid the medium entering from the inlet 5 and being directly output from the outlet 6, resulting in insufficient heat exchange with the thick film heating plate 2.

[0017] The above structure uses a thick film heating plate 2 to heat the medium flowing through the water chamber. The thick film heating plate 2 is encapsulated on the tank 3 of the middle shell 1, so that a water chamber is formed inside the tank 3. This simplifies the structure of the heating core, reduces the number of internal parts, lowers the labor cost of processing, and makes incoming material inspection easier to control. The design of the two guide channels 7 allows the medium to fully contact the thick film heating plate 2 before being output, which can evenly remove the heat from the thick film heating plate 2, making the temperature of the entire heating core stable and the safety factor high.

[0018] In another embodiment, such as Figure 3 As shown, one end of each of the two guide channels 7 is connected to the inlet 5 and the outlet 6 respectively, and the other end of each guide channel 7 extends to one end of the channel body 3 away from the inlet 5 and the outlet 6.

[0019] In another embodiment, combined Figure 1 and Figure 2As shown, the thick film heating plate 2 is fixed to the middle shell 1 by multiple bolts, and a sealing ring 8 is provided at the connection between the thick film heating plate 2 and the middle shell 1 to ensure the airtightness of the water chamber.

[0020] In another embodiment, combined Figure 1 and Figure 2 As shown, a first side cover 9 is also fixed on the outer shell 1 of the thick film heating plate 2 to enclose the thick film heating plate 2 inside the shell 1.

[0021] In another embodiment, combined Figure 1 and Figure 2 As shown, the other side of the middle shell 1 is provided with a mounting groove 10, and a control plate 11 is provided in the mounting groove 10. The control plate 11 and the thick film heating plate 2 are connected by a busbar 12. The busbar 12 serves as the intermediate hub connecting the thick film heating plate 2 and the control plate 11, while the control plate 11 is used for the entire heating core.

[0022] In another embodiment, such as Figure 3 As shown, one end of the middle shell 1 is provided with a connecting groove 13 for the busbar 12 to pass through. The busbar 12 passes through the connecting groove 13, and the two ends of the busbar 12 are welded to the thick film heating plate 2 and the control plate 11, respectively.

[0023] In another embodiment, such as Figure 1 As shown, a second side cover 14 is also fixed on the middle shell 1 on the outer side of the control plate 11 to enclose the control plate 11 inside the middle shell 1.

[0024] In another embodiment, the connection between the first side cover 9 and the second side cover 14 and the middle shell 1 is also provided with sealant to ensure the airtightness of the entire heating core.
