[0022] The utility model provides Figure 1-3 An epoxy resin heating plate as shown in the figure comprises:

[0023] Carrier layer 100;

[0024] The heating layer 200 includes a first heating strip 201 and a second heating strip 202 arranged on two sides of the carrier layer 100. The orthographic projections of the first heating strip 201 and the second heating strip 202 on the carrier layer 100 are staggered and both have a wavy structure, which has the advantages of uniform heating and good heat exchange effect. The first heating strip 201 and the second heating strip 202 are respectively provided with a female terminal 203 and a male terminal 204 at both ends;

[0025] The protective layer 300 includes a first epoxy plate 301 and a second epoxy plate 302 arranged on both sides of the heating layer 200 . The inner sides of the first epoxy plate 301 and the second epoxy plate 302 are both provided with grooves 303 .

[0026] In addition, the carrier layer 100 is made of epoxy resin board, which has excellent mechanical properties and dielectric properties, and is heat-resistant, moisture-proof, acid-resistant, alkali-resistant, and impact-resistant. This makes the epoxy resin heating plate have high-strength insulation and voltage resistance as well as good moisture-proof and flame-retardant properties, and has a high safety factor. The first heating bar 201 and the second heating bar 202 are made by etching stainless steel sheets or copper sheets, and the first heating bar 201 and the second heating bar 202 are fixed on both sides of the carrier layer 100 by a hot press.

[0027] Specifically, a plastic shell is provided on the female terminal 203 and the male terminal 204, and the central axes of the female terminal 203 and the male terminal 204 coincide with each other, so that two adjacent epoxy resin heating plates can be connected as a whole through the female terminal 203 and the male terminal 204, and the plastic shell can effectively protect the female terminal 203 and the male terminal 204.

[0028] It is worth mentioning that the first double-sided adhesive layer 205 and the second double-sided adhesive layer 206 are respectively provided on both sides of the carrier layer 100. The first double-sided adhesive layer 205 and the second double-sided adhesive layer 206 are both rectangular frame structures and are respectively fixedly sleeved on the four sides of the first heating bar 201 and the second heating bar 202. It is convenient to fix the first epoxy board 301 and the second epoxy board 302 on both sides of the carrier layer 100 through the first double-sided adhesive layer 205 and the second double-sided adhesive layer 206, and at the same time, it can effectively prevent the heat generated by the first heating bar 201 and the second heating bar 202 from affecting the first double-sided adhesive layer 205 and the second double-sided adhesive layer 206.

[0029] Specifically, the first epoxy board 301, the second epoxy board 302 and the carrier layer 100 have the same size, ensuring that the first epoxy board 301 and the second epoxy board 302 can effectively protect the two sides of the carrier layer 100, the size of the groove 303 is not less than the size of the first heating bar 201 and the second heating bar 202, and not greater than the size of the first double-sided adhesive layer 205 and the second double-sided adhesive layer 206, and the depth of the groove 303 is the same as the height of the first heating bar 201 and the second heating bar 202 protruding from the carrier layer 100, ensuring that the first heating bar 201 and the second heating bar 202 can fit at the bottom of the corresponding groove 303, which is convenient for installing the protective layer 300 and can better transfer the heat generated by the first heating bar 201 and the second heating bar 202, thereby effectively improving the thermal efficiency of the epoxy resin heating plate.

[0030] It should be noted that the total thickness of the carrier layer 100, the heating layer 200 and the protective layer 300 is 1.0 to 1.8 mm, and the size and shape of the epoxy resin heating plate can be arbitrarily made. The structure occupies very little space, and the voltage and power can also be arbitrarily designed. It can be conveniently pasted on the surface of an object to be heated and heat the object through heat conduction.

[0031] Specifically, the length of the carrier layer 100 is 50-1200 mm, the width is 50-600 mm, and the heating temperature of the heating layer 200 is 40-120°C.

[0032] Working principle: When using the epoxy resin heating plate, first stick it on the surface of the object to be heated, and then connect the two poles of the external power supply to the female terminal 203 and the male terminal 204 respectively. The current passes through the first heating strip 201 and the second heating strip 202 respectively. The first heating strip 201 and the second heating strip 202 generate heat and conduct it outward through the first epoxy board 301 and the second epoxy board 302 to achieve heating of the object. When multiple epoxy resin heating plates are needed, the female terminals 203 and the male terminals 204 corresponding to the two adjacent epoxy resin heating plates need to be plugged and fixed, and then the two poles of the external power supply are respectively connected to the female terminal 203 and the male terminal 204 of the outermost epoxy resin heating plate, and the current can pass through all the first heating strips 201 and the second heating strips 202 in turn to achieve simultaneous heating of multiple epoxy resin heating plates. The epoxy resin heating plate has an advanced design and a compact structure. By arranging a first heating strip 201 and a second heating strip 202 and arranging a groove 303 on the first epoxy board 301 and the second epoxy board 302, the first heating strip 201 and the second heating strip 202 are closer to the protective layer 300, which greatly improves the thermal efficiency of the heating plate. By arranging a female terminal 203 and a male terminal 204, multiple epoxy resin heating plates can be conveniently connected and connected to a power supply in a unified manner, which is convenient to use.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
