[0035] Next, the present disclosure will be described in detail.

[0036] With the development of the photovoltaic industry, the production demand and quality demand of photovoltaic cell modules are becoming higher and higher, so the photovoltaic equipment used to produce photovoltaic cell modules also needs to keep pace with the times to meet the production demand.

[0037] Among them, the laminator is the core equipment in the production process of the photovoltaic cell module, and its main function is to press the tempered glass plate, hot melt adhesive, monomer solar cell, hot melt adhesive, back plate (or tempered glass plate) arranged in sequence into a photovoltaic cell module by vacuum hot pressing forming. The heating method of the laminator, and its temperature control precision, temperature uniformity and the like in the laminating process will affect the quality of the photovoltaic cell module.

[0038] Based on the above needs, as shown in FIG. 1 and FIG. 2, the present disclosure provides a laminator 01, comprising a body 1, a laminating part 2, a first heating part 3, a second heating part 4 and a heat insulation part 5. The body 1 has a first wall 11 and a second wall 12 which are opposite and spaced apart. The laminating part 2 is made of elastic material, and is arranged between the first wall 11 and the second wall 12, and forms a first cavity a and a second cavity b with the first wall 11 and the second wall 12 respectively, and the first cavity a is used for accommodating a photovoltaic cell assembly 02. The first heating part 3 is used for heating the first wall 11, and the first wall 11 is used for bearing the photovoltaic cell assembly 02. The second heating part 4 is arranged in the second cavity b and connected with the second wall 12. The heat insulation part 5 is arranged between the second wall 12 and the second heating part 4, and is used for insulating the heat conducted from the second heating part 4 to the second wall 12.

[0039] It can be understood that the first wall 11 should be a structure with good heat conduction performance, for example, it can be an aluminum plate or the like.

[0040] In some examples, the first heating part 3 can be a heating sheet built in the first wall 11, and the first wall 11 is heated by energizing the heating sheet, and then the photovoltaic cell assembly 02 is heated by the first wall 11.

[0041] Of course, the first heating part 3 can also be arranged on the side of the first wall 11 away from the second wall 12 and attached to the first wall 11 to heat the first wall 11.

[0042] In some examples, the photovoltaic cell assembly 02 can be a single-glass cell assembly, and the photovoltaic cell assembly 02 comprises a tempered glass plate, a single solar cell and a back plate which are arranged in layers, and hot melt glue is arranged between the tempered glass plate and the single solar cell and between the back plate and the single solar cell. The back plate is used for providing support for the single solar cell, and the tempered glass plate is used for providing protection for the single solar cell.

[0043] In other examples, the photovoltaic cell assembly 02 can also be a double-glass cell assembly, and the photovoltaic cell assembly 02 comprises a tempered glass plate, a single solar cell and a tempered glass plate which are arranged in layers, and hot melt glue is arranged between the tempered glass plate and the single solar cell. The tempered glass plate is used for providing protection for the single solar cell, and since the double-glass cell assembly can absorb light on both sides, the power generation efficiency and power generation capacity can be ensured.

[0044] Exemplarily, the hot melt glue can be ethylene-vinyl acetate copolymer (EVA).

[0045] Exemplarily, after the photovoltaic cell assembly 02 is placed in the first cavity a, the tempered glass plate, the monomer solar cell and the back plate are arranged in sequence in the direction in which the second wall 12 points to the first wall 11. In this case, the first surface of the photovoltaic cell assembly 02 is the lower surface of the side surface of the back plate away from the monomer solar cell, and the second surface of the photovoltaic cell assembly 02 is the upper surface of the side surface of the tempered glass plate away from the monomer solar cell.

[0046] In some examples, as shown in FIG. 1 and FIG. 2, the machine body 1 further comprises a base 13, and the first wall 11 is carried on the base 13. By arranging the base 13, the base 13 can provide sufficient support for the first wall 11, and at the same time, the first wall 11 can be elevated, thereby facilitating actual processing.

[0047] In some examples, as shown in FIG. 1 and FIG. 2, the machine body 1 further comprises an upper shelf 14, which is arranged on the side of the second wall 12 away from the first wall 11 and connected with the second wall 12. The arrangement of the upper shelf 14 can facilitate the arrangement of some auxiliary components on the side of the second wall 12 away from the first wall 11, so as to ensure the smooth lamination.

[0048] In some examples, the laminating machine 01 further comprises an air charging and pressurizing assembly, which is used to communicate with the second cavity b to increase the air pressure in the second cavity b. In this way, when the photovoltaic cell assembly 02 is laminated, the air charging and pressurizing assembly is first used to charge air into the second cavity b to increase the air pressure in the second cavity b, so that the air pressure in the second cavity b is higher than that in the first cavity a. At the same time, the laminating piece 2 can protrude into the first cavity a, so as to be attached to the second surface of the photovoltaic cell assembly 02 (the side surface of the photovoltaic cell assembly 02 away from the first wall 11). Since the photovoltaic cell assembly 02 is carried on the first wall 11, the photovoltaic cell assembly 02 is pressed between the first wall 11 and the laminating piece 2 at this time. At the same time, under the cooperation of the first heating piece 3 and the second heating piece 4, the lamination of the photovoltaic cell assembly 02 is realized.

[0049] Exemplarily, the air charging and pressurizing assembly can comprise a high-pressure air charging pump and a control valve. The air charging port of the high-pressure air charging pump is connected with the second cavity b through the control valve. The control valve is used to realize the communication and isolation between the high-pressure air charging pump and the second cavity b, so as to realize air charging and pressurizing when the communication is realized and to stop pressurizing when the isolation is realized.

[0050] In some examples, the elastic material used to make the laminating piece 2 can comprise rubber or polyurethane, etc. The rubber can be natural rubber or synthetic rubber. The elastic material is not limited as long as it can be elastically deformed and does not cause excessive damage to the photovoltaic cell assembly 02 after being in contact with the photovoltaic cell assembly 02.

[0051] In some examples, the laminate 2 is a sheet structure with uniform thickness, and the thickness direction of the sheet structure is consistent with the arrangement direction of the first wall 11 and the second wall 12, so that the elastic deformation of the laminate 2 can be facilitated.

[0052] Through the above arrangement, since the laminate 2 is arranged between the first wall 11 and the second wall 12 and forms independent first cavity a and second cavity b with the first wall 11 and the second wall 12 respectively, and the laminate 2 is made of elastic material, by changing the air pressure in the first cavity a and the second cavity b, the laminate 2 can be bulged to the first cavity a or the second cavity b, so as to realize the lamination of the photovoltaic cell assembly 02.

[0053] Specifically, the photovoltaic cell assembly 02 is placed on the first wall 11, then the first cavity a is in a low pressure state and the second cavity b is in a high pressure state, so that the laminate 2 can be bulged to the first cavity a and pressed to the second surface of the photovoltaic cell assembly 02. At the same time, the first heating member 3 and the second heating member 4 are started, so that the first heating member 3 can heat the first wall 11, so that the first wall 11 is heated and adhered to the first surface of the photovoltaic cell assembly 02, and the second heating member 4 can heat the laminate 2 and transfer heat to the laminate 2, since the laminate 2 is adhered to the second surface of the photovoltaic cell assembly 02, the heat on the laminate 2 can be transferred to the second surface of the photovoltaic cell assembly 02, so as to realize the double-sided heating of the photovoltaic cell assembly 02, and ensure the heating effect and efficiency of the photovoltaic cell assembly 02, so that the hot melt adhesive in the photovoltaic cell assembly 02 can be quickly and uniformly melted, the lamination efficiency is improved, and the quality of the laminated photovoltaic cell assembly 02 is ensured.

[0054] In addition, since the second heating member 4 is provided with the heat insulation member 5 between the second wall 12, the heat insulation member 5 can play a heat insulation effect, so as to avoid the heat generated by the second heating member 4 from being transferred to the second wall 12 and then to the outside of the second cavity b, thereby avoiding heat loss and ensuring the heating effect of the second heating member 4 on the laminate 2 and the heating efficiency. Moreover, the second heating member 4 can also avoid direct contact with the second wall 12, and the second heating member 4 can avoid heating the second wall 12, so that the material of the second wall 12 does not need to be specially selected and arranged, and the production convenience can be improved.

[0055] In some embodiments, as shown in FIG. 1, the laminating machine 01 further comprises a heat preservation member 6 made of heat preservation material, and the heat preservation member 6 is carried on the side of the second wall 12 away from the first wall 11.

[0056] The heat preservation material can be foamed polyurethane material, inorganic heat preservation material or organic heat preservation material.

[0057] In some examples, as shown in FIG. 1, the upper shelf 14 and the second wall 12 can form a bearing space 141, and the heat preservation member 6 can be arranged in the bearing space 141, so that the heat preservation member 6 can be fixed conveniently. For example, the heat preservation member 6 can be filled in the bearing space 141.

[0058] In other examples, the heat preservation member 6 can also be connected directly to the side surface of the second wall 12 away from the first wall 11, so as to perform heat preservation.

[0059] Exemplarily, the heat preservation member 6 covers the side surface of the second wall 12 away from the first wall 11, so that the heat preservation effect of the heat preservation member 6 can be guaranteed.

[0060] By arranging the heat preservation member 6 on the side of the second wall 12 away from the first wall 11, the heat preservation member 6 can play a heat preservation function to perform heat preservation on the second cavity b, so as to slow down the loss of temperature in the second cavity b and guarantee the heating effect of the second heating member 4 during the lamination process.

[0061] The lamination member 2 can form the first cavity a directly with the first wall 11, and can form the second cavity b directly with the second wall 12, or can form the first cavity a with other structures and can form the second cavity b with other structures. Details are described below.

[0062] In some examples, as shown in FIG. 3, the laminator 01 further comprises a first pressing strip 7 and a second pressing strip 8 located between the first wall 11 and the second wall 12. The first pressing strip 7 is arranged on the first wall 11 and surrounds the first wall 11 in the extension direction of the first wall 11 to form a first groove with the first wall 11. The second pressing strip 8 is arranged on the second wall 12 and surrounds the second wall 12 in the extension direction of the second wall 12 to form a second groove with the second wall 12. The lamination member 2 is clamped between the first pressing strip 7 and the second pressing strip 8 and covers the groove opening of the first groove and the groove opening of the second groove to form the first cavity a and the second cavity b, respectively.

[0063] It can be understood that the first pressing strip 7 surrounds the first wall 11 in the extension direction of the first wall 11 to form a first groove with the first wall 11, which means that the first wall 11 serves as the groove bottom of the first groove and the first pressing strip 7 serves as the peripheral wall of the first groove. Similarly, the second pressing strip 8 surrounds the second wall 12 in the extension direction of the second wall 12 to form a second groove with the second wall 12, which means that the second wall 12 serves as the groove bottom of the second groove and the second pressing strip 8 serves as the peripheral wall of the second groove.

[0064] In addition, when laminating the photovoltaic cell assembly 02, at least one of the first pressing strip 7 and the second pressing strip 8 can be connected to the lamination member 2, so that the stability of the lamination member 2 clamped by the first pressing strip 7 and the second pressing strip 8 can be guaranteed, and the normal lamination can be ensured.

[0065] Exemplarily, the first pressing strip 7 is fixed to the first wall 11, the laminated piece 2 is only carried on the first pressing strip 7 and is not connected with the first pressing strip 7 but is connected with the second pressing strip 8. In this way, when the photovoltaic cell assembly 02 to be laminated is placed into the first cavity a or the laminated photovoltaic cell assembly 02 is taken out of the first cavity a, the second wall 12 can be moved to drive the second pressing strip 8 to move integrally with the laminated piece 2, so that the slot of the first slot is in an open state, that is, is not covered by the laminated piece 2, at this time, the photovoltaic cell assembly 02 to be laminated can be placed into the first cavity a or the laminated photovoltaic cell assembly 02 is taken out of the first cavity a, thereby facilitating the taking and placing of the photovoltaic cell assembly 02.

[0066] In some examples, the first pressing strip 7 and the second pressing strip 8 can also be made of heat insulation materials, so that the heat loss of the first cavity a and the second cavity b can be further reduced, and the efficiency and effect of lamination can be improved.

[0067] In some examples, in the arrangement direction of the first wall 11 and the second wall 12, the first pressing strip 7 can have a regular shape such as a square, a circle or a triangle, or can have an irregular shape.

[0068] In some examples, in the arrangement direction of the first wall 11 and the second wall 12, the second pressing strip 8 can have a regular shape such as a square, a circle or a triangle, or can have an irregular shape.

[0069] In some examples, in the arrangement direction of the first wall 11 and the second wall 12, the first pressing strip 7 can have the same shape as the second pressing strip 8, so that as long as the first pressing strip 7 and the second pressing strip 8 are accurately aligned, the laminated piece 2 can be stably clamped between the first pressing strip 7 and the second pressing strip 8, so that the stability of the laminated piece 2 arranged between the first pressing strip 7 and the second pressing strip 8 can be ensured when the photovoltaic cell assembly 02 is laminated.

[0070] In some examples, a first sealing member 9 is arranged between the first pressing strip 7 and the first wall 11, and the first sealing member 9 is arranged in the circumferential direction of the first pressing strip 7. In this way, the sealing between the first pressing strip 7 and the first wall 11 can be ensured, so that the sealing of the first cavity a and the stability of lamination can be ensured. And / or, a second sealing member is arranged between the first pressing strip 7 and the laminated piece 2, and the second sealing member is arranged in the circumferential direction of the first pressing strip 7. In this way, the sealing between the first pressing strip 7 and the laminated piece 2 can be ensured, so that the sealing of the first cavity a and the stability of lamination can be ensured.

[0071] The first sealing member 9 can be a first sealing ring, or the first sealing member 9 can include a plurality of first sealing segments arranged in sequence and spaced or arranged closely in the circumferential direction of the first pressing strip 7.

[0072] Similarly, the second sealing member can be a second sealing ring, or, along the circumferential direction of the first pressing strip 7, the second sealing member can also include a plurality of second sealing segments, which are arranged in sequence with intervals or in close proximity.

[0073] In addition, the first sealing member 9 can be arranged in a first sealing groove, which can be formed on the first wall 11 and / or the first pressing strip 7, and is arranged along the circumferential direction of the first pressing strip 7, so as to ensure the stability of the arrangement of the first sealing member 9. Similarly, the second sealing member can be arranged in a second sealing groove, which is formed on the first pressing strip 7 and is arranged along the circumferential direction of the first pressing strip 7, so as to ensure the stability of the arrangement of the second sealing member, and also avoid forming the second sealing groove on the laminated member 2, so as to ensure the structural strength of the laminated member 2 and the stability of the lamination.

[0074] In some examples, the second pressing strip 8 can be an integral structure with the upper shelf 14. In this way, the upper shelf 14 and the second pressing strip 8 can be processed at one time, which can facilitate the processing of the upper shelf 14 and the second pressing strip 8.

[0075] In this case, a third sealing member 10 can be arranged between the second pressing strip 8 and the laminated member 2, and the third sealing member 10 is arranged along the circumferential direction of the second pressing strip 8. In this way, the sealing between the laminated member 2 and the second pressing strip 8 can be ensured, so as to ensure the sealing of the second cavity b and the stable lamination.

[0076] The third sealing member 10 can be a third sealing ring, or, along the circumferential direction of the second pressing strip 8, the third sealing member 10 can also include a plurality of third sealing segments, which are arranged in sequence with intervals or in close proximity.

[0077] In addition, the third sealing member 10 can be arranged in a third sealing groove, which is formed on the second pressing strip 8 and is arranged along the circumferential direction of the second pressing strip 8, so as to ensure the stability of the arrangement of the third sealing member 10, and also avoid forming the third sealing groove on the laminated member 2, so as to ensure the structural strength of the laminated member 2 and the stability of the lamination.

[0078] Through the above arrangement, the first pressing strip 7 can play a bearing role on the laminated member 2, so that the laminated member 2 has a space (first groove body) with the first wall 11, so that the laminated member 2 can be surrounded by the first pressing strip 7 and the first wall 11 to form a first cavity a. Similarly, the second pressing strip 8 can also make the laminated member 2 have a space (second groove body) with the second wall 12, so that the laminated member 2 can be surrounded by the second pressing strip 8 and the second wall 12 to form a second cavity b. In this way, the formation of the first cavity a and the second cavity b can be facilitated.

[0079] In addition, by reasonably setting the connection relationship between the first pressing strip 7 and the laminated piece 2 and the first wall 11, and the connection relationship between the second pressing strip 8 and the laminated piece 2 and the second wall 12, the photovoltaic cell module 02 can be conveniently taken and placed, or the heat insulation piece 5 and the second heating piece 4 can be conveniently installed and disassembled.

[0080] The position and connection relationship between the second heating piece 4 and the heat insulation piece 5, and the structure of the second heating piece 4 itself have a great influence on the heating effect of the photovoltaic cell module 02, which will be described in detail below.

[0081] In some embodiments, as shown in FIG. 4, the vertical projection of the second heating piece 4 on the second wall 12 is entirely located in the heat insulation piece 5.

[0082] It can be understood that in the direction perpendicular to the second wall 12 (the X direction in FIG. 4), the size of the heat insulation piece 5 should be within a suitable range, so as to reduce the material cost of the heat insulation piece 5 as much as possible on the basis of ensuring the heat insulation effect.

[0083] In some examples, as shown in FIG. 4, in the direction perpendicular to the second wall 12, the second heating piece 4 can be completely coincident with the heat insulation piece 5, so as to not only maximize the heat insulation effect, but also minimize the material cost of the heat insulation piece 5 on this basis.

[0084] Of course, in other examples, as shown in FIG. 5, the vertical projection of the second heating piece 4 on the second wall 12 is entirely located in the heat insulation piece 5, but only occupies part of the heat insulation piece 5. In this way, the heat insulation effect of the heat insulation piece 5 can also be maximized.

[0085] Through the above setting, in the direction perpendicular to the second wall 12, the second heating piece 4 completely falls on the heat insulation piece 5, and the heat insulation piece 5 can completely insulate the second heating piece 4 from the second wall 12. In this way, the heat generated by the second heating piece 4 can be maximally avoided from being conducted to the outside of the second cavity b through the second wall 12, so as to maximally improve the utilization rate of the heat generated by the second heating piece 4, and ensure the laminating effect and the laminating efficiency.

[0086] Of course, in other embodiments, the vertical projection of the second heating piece 4 on the second wall 12 can also be only partially located in the heat insulation piece 5.

[0087] In some embodiments, as shown in FIG. 4, the vertical projection of the second heating piece 4 on the first wall 11 covers the photovoltaic cell module 02.

[0088] In some examples, as shown in FIG. 4, in the direction perpendicular to the first wall 11, the second heating member 4 can be fully overlapped with the photovoltaic cell assembly 02, in this way, the second heating member 4 can not only maximize the baking of the part of the laminate 2 opposite to it, so that the laminate 2 can be better heated, and then heat the photovoltaic cell assembly 02, but also on this basis, the material cost of the second heating member 4 can be reduced as much as possible.

[0089] Of course, in other examples, as shown in FIG. 6, in the direction perpendicular to the first wall 11, the second heating member 4 can also partially cover the first wall 11 on the basis of fully covering the photovoltaic cell assembly 02. In this way, the maximum heating effect of the photovoltaic cell assembly 02 can also be ensured.

[0090] Through the above arrangement, the second heating member 4 can maximize the baking of the part of the laminate 2 opposite to it, so that the laminate 2 can be better heated, and then heat the photovoltaic cell assembly 02, so as to achieve a better heating effect.

[0091] Of course, in other examples, the vertical projection of the second heating member 4 on the first wall 11 can also cover at least part of the photovoltaic cell assembly 02, or not cover the photovoltaic cell assembly 02.

[0092] In some examples, as shown in FIG. 7, the second heating member 4 includes a heating layer 41 and a heat-conducting layer 42 connected in layers, the heating layer 41 is arranged between the heat-conducting layer 42 and the heat insulation member 5, and the heating layer 41 is used to generate heat.

[0093] The heating layer 41 can be in the form of electric heating, for example, can be resistance heating.

[0094] In addition, the heat-conducting layer 42 can be a structure with good heat-conducting performance, such as an aluminum layer or a copper layer.

[0095] Through the above arrangement, the heating layer 41 in the second heating member 4 can be used to provide heat, and the heat-conducting layer 42 can not only efficiently conduct heat to the second cavity b, but also protect the heating layer from being damaged.

[0096] In some examples, as shown in FIG. 7, the second heating member 4 further includes a heat insulation layer 43 arranged between the heating layer 41 and the heat insulation member 5 and connected with the heating layer 41.

[0097] The material of the heat insulation layer 43 can include a composite fiber material with heat insulation performance, for example, the heat insulation layer 43 can be composed of glass fiber and resin material, and the resin material can include polyurethane, epoxy resin, etc.

[0098] By arranging the heat insulation layer 43 between the heat generating layer 41 and the heat insulation member 5, the heat insulation layer 43 can further play a heat insulation effect, thereby insulating the heat generated by the heat generating layer 41 from being conducted to the heat insulation member 5, and further avoiding the heat generated by the heat generating layer 41 from being conducted to the second wall 12, and better ensuring the laminated heating effect. In addition, since the heat insulation layer 43 is connected with the heat generating layer 41, when the second heating member 4 is not installed on the heat insulation member 5, the heat insulation layer 43 can protect the heat generating layer 41 to ensure that the heat generating member can normally generate heat, and ensure the use reliability of the second heating member 4.

[0099] In some embodiments, as shown in FIG. 2 and FIG. 3, the laminating machine 01 further comprises a fastener 101, which sequentially passes through the second heating member 4, the heat insulation member 5, and is connected with the second wall 12.

[0100] In some examples, the fastener 101 can be a screw, and first mounting holes and second mounting holes corresponding to the arrangement are respectively formed on the second heating member 4 and the heat insulation member 5, so that the screw sequentially passes through the first mounting hole, the second mounting hole and extends into the second wall 12 to realize the connection.

[0101] In some examples, the number of fasteners 101 is multiple, and the multiple fasteners 101 are arranged at different positions of the second heating member 4 in a uniform or irregular manner, thereby ensuring the firmness of the fixation.

[0102] Through the above arrangement, the fastener 101 sequentially passes through the second heating member 4 and the heat insulation member 5, thereby fixing the second heating member 4 to the second wall 12 and fixing the heat insulation member 5 between the second heating member 4 and the second wall 12. Since the fastener 101 passes through the second heating member 4 and the heat insulation member 5, the firmness of the fixation of the second heating member 4, the heat insulation member 5 and the second wall 12 is ensured, and one-time fixation of the three can be realized, thereby simplifying the fixation process.

[0103] Of course, in other examples, the heat insulation member 5 can be fixed to the second wall 12 first, and then the second heating member 4 is fixed to the heat insulation member 5.

[0104] In some embodiments, as shown in FIG. 2, the number of the second heating member 4 and the heat insulation member 5 is multiple, and they are arranged correspondingly. In the extension direction of the second wall 12, multiple heat insulation members 5 are laid on the second wall 12, and the second heating member 4 is located on the side of the corresponding heat insulation member 5 away from the second wall 12.

[0105] In some examples, the plurality of heat insulating members 5 can be arranged in a square array on the second wall 12, and the plurality of second heating members 4 can also be arranged in a square array on the second wall 12. Then, in the extension direction of the second wall 12, the temperature uniformity of the different parts of the laminated member 2 heated by the plurality of second heating members 4 can be ensured, so as to ensure the laminating quality of the photovoltaic cell assembly 02 after laminating.

[0106] Of course, in other examples, the plurality of heat insulating members 5 can also be laid in an irregular manner on the second wall 12.

[0107] In some examples, the laminating machine 01 can laminate a plurality of photovoltaic cell assemblies 02 at one time, so that each photovoltaic cell assembly 02 corresponds to at least one second heating member 4, so as to ensure the heating effect of each photovoltaic cell assembly 02.

[0108] In some examples, the laminating machine 01 further comprises a controller, which is electrically connected with the plurality of second heating members 4 and can control the heating temperature of each second heating member 4 independently, so as to flexibly control the heating temperature of each second heating member 4, thereby flexibly and accurately controlling the temperature of different positions of the laminated member 2 and ensuring the laminating effect.

[0109] Through the above arrangement, the plurality of second heating members 4 can correspond to different positions of the laminated member 2 and can independently heat different positions of the laminated member 2, so that in the case of laminating a plurality of photovoltaic cell assemblies 02 at one time by the laminating machine 01, the plurality of second heating members 4 can correspond to the plurality of photovoltaic cell assemblies 02 respectively, so as to realize the independent heating of different photovoltaic cell assemblies 02. In addition, this design can also control the area of the second heating member 4 and the heat insulating member 5 in the extension direction of the second wall 12, thereby facilitating the installation of the second heating member 4 and the heat insulating member 5.

[0110] Of course, in other examples, the number of second heating members 4 and heat insulating members 5 can also be only one, and in this case, in order to maximize the heating effect of the second heating member 4, the second heating member 4 can completely cover the entire second wall 12 in the extension direction of the second wall 12.

[0111] In some examples, the material of the heat insulating member 5 comprises a composite fiber material with heat insulating performance.

[0112] The heat insulating member 5 can be composed of glass fiber and resin material, for example, the resin material can include polyurethane, epoxy resin, etc.

[0113] By setting the heat insulating member 5 as a composite fiber material having heat insulating properties, not only the excellent heat insulating effect of the heat insulating member 5 is ensured, but also the weight of the heat insulating member 5 is reduced, and the structural strength of the heat insulating member 5 is ensured.

[0114] Of course, in other embodiments, the material of the heat insulating member 5 can also include an organic material, for example, the organic material can be polystyrene foam or polyurethane foam, etc.

[0115] The above is only the preferred embodiment of the present disclosure, and does not limit the patent scope of the present disclosure, and any equivalent structure or equivalent flow transformation made by using the content of the present disclosure specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present disclosure.
