DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0024] See also Figures 1-7 The present application provides a single-plate double-sided thick film heater, including a heater body 10, with heating chambers 20 provided at the top and bottom of the heater body 10. Specifically, the two heating chambers 20 are symmetrically arranged about the middle part of the heater body 10, and the two heating chambers 20 are both equipped with heat dissipation fin groups 30. The heater body 10 is embedded with a single-plate double-sided heating plate 40, as shown in the attached figure. Figure 7 As shown in the figure, the single-board double-sided heating plate 40 is specifically printed on both sides of the original rare earth thick film heating plate, so as to achieve double-sided heating. Furthermore, the single-board double-sided heating plate 40 is located between the two groups of heat dissipation fin groups 30, so that the single-board double-sided heating plate 40 generates heat to realize heat transfer to the heat dissipation fin groups 30 in the heating chambers 20 on both sides. When the fluid flows through the two heating chambers 20, heat exchange is realized between the heat dissipation fin groups 30 to heat the fluid. A sealing plate 50 is connected to each of the two heating chambers 20. Specifically, the two sealing plates 50 are respectively connected to the top and bottom of the heater body 10, and the specific connection structure is connected through a screw connection structure. The two sealing plates 50 respectively close the openings of the two heating chambers 20.

[0025] See Figure 3 and 6, the bottoms of the two heating chambers 20 are respectively provided with a water inlet groove 210 and a water outlet groove 220, and the heat dissipation fin group 30 is located between the water inlet groove 210 and the water outlet groove 220. Specifically, the water inlet groove 210 and the water outlet groove 220 are fluid buffer areas, so that the fluid fills the water inlet groove 210 so that the fluid covers the entire heat dissipation fin group 30. Further, a water inlet joint 110 and a water outlet joint 120 are installed on the outer wall of the heater body 10. The two water inlet grooves 210 are connected to the water inlet joint 110, and the two water outlet grooves 220 are connected to the water outlet joint 120. In the specific setting, the water inlet joint 110 and the water outlet joint 120 are connected to the heater body The outer wall of the body 10 is fixedly connected, a first through hole is opened at one end of the two water inlet grooves 210, and a second through hole is opened at one end of the two water outlet grooves 220. The two first through holes are connected to the water inlet joint 110, and the two second through holes are connected to the water outlet joint 120, so that the fluid flows through the water inlet joint 110 to the two water inlet grooves 210. Furthermore, a flow equalizing plate 230 is fixedly installed at the bottom of the two heating chambers 20, and the flow equalizing plate 230 is arranged close to the water inlet groove 210. Specifically, a plurality of through holes are opened on the flow equalizing plate 230, and the plurality of through holes are evenly distributed, so that the fluid in the water inlet groove 210 passes through the plurality of through holes, thereby covering the entire heat dissipation fin group 30.

[0026] See Figure 3 The heat dissipation fin group 30 is composed of a plurality of heat dissipation fins, and the plurality of heat dissipation fins are evenly distributed on the bottom of the heating chamber 20. Specifically, the heat dissipation fins can be designed to be arc-shaped to increase the time that the fluid stays in the heating chamber 20, thereby improving the heat exchange effect between the fluid and the heat dissipation fins.

[0027] See Figure 4 and 5 The middle part of the heater body 10 is provided with an assembly cavity 130, the single-plate double-sided heating plate 40 is inserted into the assembly cavity 130, and a heat conducting medium is filled between the assembly cavity 130 and the single-plate double-sided heating plate 40. Specifically, the single-plate double-sided heating plate 40 is inserted into the assembly cavity 130, as shown in the attached Figure 7 As shown in the figure, there is a gap between the single-board double-sided heating plate 40 and the assembly cavity 130. The gap can be filled with a heat-conducting medium so that heat is radiated to the heating cavities 20 on both sides. The fluid can be water, so that the single-board double-sided heating plate 40 does not come into direct contact with water, greatly reducing water loss.

[0028] See Figures 3-7One of the side walls of the sealing plate 50 is fixedly connected with a protective shell 510, the protective shell 510 is arranged in close contact with the side wall of the heater body 10, the other sealing plate 50 is detachably connected with the protective shell 510, specifically, the joint part of the single-plate double-sided heating plate 40 is arranged in the protective shell 510 to protect the single-plate double-sided heating plate 40, further, the first sealing strip 60 is arranged between the two sealing plates 50 and the top and bottom of the heater body 10, specifically, the recesses matched with the first sealing strip 60 are arranged on the top and bottom of the heater body 10, the second sealing strip 70 is arranged between the top of the protective shell 510 and the sealing plate 50, the recess matched with the second sealing strip 70 is arranged on the top of the protective shell 510, the two recesses are communicated, and the second sealing strip 70 is arranged in connection with the first sealing strip 60, so that the sealing of the heating cavity 20 is realized.

[0029] When the single-plate double-sided thick-film heater works, the water inlet joint 110 and the water outlet joint 120 are connected with the existing air conditioner heater system, the single-plate double-sided heating plate 40 is powered to heat, heat is transferred to the two heating cavities 20, so that the heat dissipation area is increased through the heat dissipation fin groups 30 in the heating cavities 20, the fluid enters the two water inlet grooves 210 through the water inlet joint 110, the fluid fills the water inlet grooves 210, and then flows to the two heat dissipation fin groups 30, and then the fluid exchanges heat with the heat dissipation fin groups 30 when flowing through the heat dissipation fin groups 30, the heated fluid enters the water outlet groove 220, and then is discharged through the water outlet joint 120, so that the purpose of heating the fluid is achieved.

[0030] It should be noted that the specific model and specification of the heater body 10 and the single-plate double-sided heating plate 40 need to be selected and determined according to the actual specification of the device, and the specific selection and calculation method adopts the existing technology in the art, so it will not be described in detail.

[0031] The power supply of the heater body 10 and the single-plate double-sided heating plate 40 and its principle are clear to those skilled in the art, and will not be described in detail here.
