[0034] like Figure 1-Figure 5 As shown, a heat pipe type heating device comprises a heat exchanger box 1, a heat source input end 2 is arranged at the bottom of the heat exchanger box 1, and a heat source output end 3 is arranged at the top of the heat exchanger box 1. In this embodiment, the heat source of the waste heat is mainly hot water after use of the equipment or hot water generated. The inner cavity of the heat exchanger box 1 is arranged from the top to the bottom with a plurality of partitions 4, and the plurality of partitions 4 divide the inner cavity of the heat exchanger box 1 into a plurality of heat exchange chambers 5. Two adjacent heat exchange chambers 5 are connected, so that hot water with waste heat is input from the heat source input end 2, and heat exchange is performed through the plurality of heat exchange chambers 5. Finally, Output from the heat source output end 3, a plurality of heat pipe assemblies 6 are arranged in the heat exchanger box 1, one end of the plurality of heat pipe assemblies 6 penetrates the heat exchange chamber 5 and extends to the bottom of the heat exchanger box 1, and the other end penetrates the top of the heat exchanger box 1 and extends into the wind box 7, a plurality of fans 8 are arranged on one side of the wind box 7, a hot air outlet 9 is arranged on the other side of the wind box 7, and the hot air outlet 9 is arranged opposite to the fan 8. The plurality of heat pipe assemblies 6 can perform heat exchange in the heat exchange chamber 5 and transfer the heat to the wind box 7, and the heat is blown out in the form of hot air through the fan 8, so as to achieve a heating effect;

[0035] In summary, the heat exchanger box 1 is divided into a plurality of heat exchange chambers 5 by arranging the partition 4, so as to slow down the flow speed of the hot water, and make the hot water exchange heat with the heat pipe assembly 6 for many times during the flow process, thereby improving the waste heat absorption and conversion efficiency. The other end of the heat pipe assembly 6 extends to the bellows 7, and the heat transferred from the heat pipe assembly 6 is blown out in the form of hot air by the fan 8 arranged on the bellows 7, thereby achieving a heating effect and improving the utilization efficiency of the waste heat. In addition, the whole device has a simple structure, low cost and good applicability.

[0036] like Figure 1-Figure 2 and Figure 5As shown, the heat pipe assembly 6 includes a heat pipe body 601, and a plurality of heat exchange folded plates 602 for increasing the heat exchange area are arranged along the axial direction on the heat pipe body 601. A space for the flow of heat source and air is formed between two adjacent heat exchange folded plates 602. By arranging a plurality of heat exchange folded plates 602 along the axial direction on the heat pipe body 601, the heat exchange folded plates 602 increase the contact area between the heat pipe body 601 and the heat source and the air, thereby increasing the heat exchange area, thereby improving the absorption and conversion efficiency of the waste heat of the heat source. At the same time, the bending structure of the heat exchange folded plates 602 can change the flow direction of the heat source and the air, thereby increasing the heat exchange efficiency.

[0037] like Figure 1-Figure 2 and Figure 5 As shown, the heat pipe body 601 located in the heat exchanger housing 1 is the evaporation section 6011, which can absorb the waste heat of the hot water flowing in the heat exchange chamber 5, and convert the medium in the heat pipe body 601 from liquid state to vapor state, and transfer it to the condensation section 6012. The heat pipe body 601 located in the wind box 7 is the condensation section 6012, and the medium in the condensation section 6012 releases heat from vapor state to liquid state, and heats the air through the released heat. At the same time, the liquid medium in the heat pipe body 601 returns to the evaporation section 6011 to achieve recycling.

[0038] The evaporation section 6011 passes through a plurality of baffles 4 in sequence, and the end of the evaporation section 6011 is fixed to the bottom of the heat exchanger housing 1 through a first fixing block 10;

[0039] The end of the condensing section 6012 is fixed to the top of the wind box 7 through the second fixing block 11, and the heat pipe body 601 is fixed through the first fixing block 10 and the second fixing block 11.

[0040] like Figure 1-Figure 2 and Figure 5 As shown, the heat exchange folded plate 602 is annular in structure, the inner circle of the heat exchange folded plate 602 is connected to the heat pipe body 601, and the heat exchange folded plate 602 includes a first plate body 6021, a second plate body 6022 and a third plate body 6023 which are arranged in sequence from the inside to the outside, the first plate body 6021 and the third plate body 6023 are arranged in parallel, the second plate body 6022 is arranged obliquely, and is respectively connected to the first plate body 6021 and the second plate body 6022, and the flow direction of the hot water and air flowing through the heat exchange folded plate 602 is changed by the inclined second plate body 6022, thereby increasing the contact area and the number of contacts.

[0041] like Figure 1-Figure 2 and Figure 5 As shown, the first plate body 6021, the second plate body 6022 and the third plate body 6023 form an integral bending structure. By adopting the integral bending structure to manufacture the heat exchange folding plate 602, processing is convenient, the manufacturing process is simple, and process steps are saved.

[0042] like Figure 1 As shown, a seal 12 is further provided between the heat pipe body 601 and the heat exchanger housing 1. The seal 12 is sleeved on the heat pipe body 601. The seal 12 enhances the sealing between the heat pipe body 601 and the heat exchanger housing 1, thereby preventing the hot water in the heat exchanger housing 1 from leaking out.

[0043] like Figure 1 As shown, several heat exchange chambers 5 are connected in an S-shaped structure. By connecting several heat exchange chambers 5 in an S-shaped structure, the length of hot water flowing in the heat exchanger box 1 is extended, thereby increasing the number of heat exchanges and the heat exchange efficiency between the hot water and the heat pipe assembly 6, and improving the waste heat absorption and conversion efficiency of the heat pipe heating device.

[0044] like Figure 1 and Figure 3 As shown, a number of grille pages 13 with adjustable angles are arranged at the hot air outlet 9, and the hot air outlet direction and angle can be adjusted through the grille pages 13. The grille pages 13 can be adjusted manually or by other electric methods, which is again not limited.

[0045] like Figure 4 As shown, at least two rows of heat pipe assemblies 6 are provided and arranged in a staggered manner. By providing at least two rows of heat pipe assemblies 6 and arranging them in a staggered manner, the flowing air can be heated at least twice, thereby improving the heating effect.

[0046] For ease of understanding, the working process of this embodiment is given below:

[0047] like Figure 1-Figure 5 As shown, first, hot water enters the heat exchanger box 1 through the heat source input end 2, and passes through a plurality of heat exchange chambers 5 in sequence under the obstruction of the partition 4. In the process of passing through the plurality of heat exchange chambers 5, the hot water continuously exchanges heat with a plurality of heat pipe assemblies 6 arranged in the heat exchanger box 1. The medium in the heat pipe assembly 6 absorbs the heat of the hot water and converts it from liquid to vapor, and is transported from the evaporation section 6011 to the condensation section 6012. Since the condensation section 6012 is located in the bellows 7, the fan 8 on the bellows 7 continuously blows air, and the flowing air will blow away the heat of the condensation section 6012 to form hot air to achieve the heating effect, and the medium for heat dissipation in the condensation section 6012 is converted from vapor to liquid and flows back to the evaporation section 6011 to achieve recycling. The temperature of the hot water after heat exchange and absorption by the heat pipe assembly 6 is reduced and output through the heat source output end 3.

[0048] In summary, the utility model provides a heat pipe type heating device with a simple structure and high waste heat absorption and conversion efficiency, and can directly convert waste heat into hot air for use.

[0049] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
