Heat can be transferred spontaneously from a high-temperature object to a low-temperature object, but cannot spontaneously proceed in the opposite direction. The working principle of a heat pump is that it is a mechanical device that forces heat to flow from a low-temperature object to a high-temperature object in a reverse cycle. It consumes only a small amount of reverse cycle net work to obtain a large amount of heating capacity, and can effectively utilize low-grade thermal energy that is difficult to use to achieve energy-saving purposes.

[0003] However, the prior art still has the following problems:

[0004] First, the waste heat recovery heat pump device of the prior art has limited heating effect, and the heat absorption and release effect needs to be strengthened. When the existing heat pump device is in use, the heat absorption structure design is relatively simple, the heat absorption efficiency is limited, and the speed of transferring heat to water is not high;

[0005] Secondly, the waste heat recovery heat pump device of the prior art has heat loss during heat transmission. A lot of heat will be lost through the outer surface of the high-temperature steam transmission pipe. If the lost heat can be recovered as waste heat, the heating effect of the heat pump can be further improved.

[0006] In view of the above problems, the inventors proposed a new type of waste heat recovery heat pump device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1: Figure 1-3As shown, the utility model provides a novel waste heat recovery type heat pump device, including a base plate 1, a water tank 6 is provided on one side of the upper end of the base plate 1, a plurality of heat absorbing sheets 2 are fixedly provided on the other side of the upper end of the base plate 1, a heat transfer pipe 3 is commonly penetrated by the heat absorbing sheets 2, a delivery pipe 35 is fixedly provided at one end of the heat transfer pipe 3, an output pipe 31 is fixedly provided at one end of the delivery pipe 35, a compressor 4 and an expansion valve 5 are fixedly provided on the upper end of the base plate 1, one end of the output pipe 31 is fixedly connected to the compressor 4, and a heat transfer pipe 32 is provided at the other end of the compressor 4, the heat transfer pipe 32 is communicated with the water tank 6, a cold pipe 33 is provided on the outer surface of the water tank 6, a heat dissipation pipe 61 is provided inside the water tank 6, a hot water inlet 63 and a cold water inlet 62 are provided on the outer end of the outer surface of the water tank 6, one end of the cold pipe 33 is fixedly connected to the expansion valve 5, and a return pipe 34 is fixedly provided between one end of the expansion valve 5 and the heat transfer pipe 3, water to be heated is stored in the water tank 6, refrigerant is stored in the heat transfer pipe 3, The heat plate 2 is placed beside the hot water pipe or the heating part of the machine to recover the waste heat. The heat in the air is transferred to the heat transfer pipe 3 through the heat absorption plate 2. When the refrigerant absorbs heat and changes from liquid to low-pressure gas, it enters the compressor 4 through the delivery pipe 35 and the output pipe 31. The compressor 4 increases the pressure and temperature of the gas, and then transfers it to the water tank 6 through the heat transfer pipe 32. The high-temperature and high-pressure gas passes through the water tank 6 through the heat dissipation pipe 61. The hot gas releases heat to the water in the water tank 6, thereby achieving the effect that the cold water entering the cold water port 62 is converted into hot water by the hot water port 63. When the heat of the refrigerant is released, the refrigerant changes from gas to high-pressure liquid. The low-temperature and high-pressure liquid refrigerant enters the expansion valve 5 through the cold pipe 33. The expansion valve 5 reduces its pressure and temperature, thereby becoming a normal liquid refrigerant. The liquid refrigerant then flows into the heat transfer pipe 3 through the return pipe 34 and repeats the cycle. The structural design is simple and reasonable, and the heating effect of the heat pump is good.

[0021] An acceleration plate 7 is provided on one side of the upper end of the base plate 1, and twelve fans 71 distributed in a rectangular shape are embedded at the outer end of the acceleration plate 7. Twelve heat absorbing sheets 2 are provided, and the twelve heat absorbing sheets 2 are distributed at equal intervals. The fans 71 on the acceleration plate 7 blow air toward the heat absorbing sheets 2, thereby increasing the ability of warm air to transfer heat to the refrigerant and improving the waste heat recovery efficiency.

[0022] Two support blocks 64 are fixedly provided at the lower end of the water tank 6 , and the lower ends of the support blocks 64 are fixedly connected to the upper end of the bottom plate 1 . The support blocks 64 improve the connection structure strength of the water tank 6 .

[0023] Both ends of the heat dissipation pipe 61 are respectively connected to the cold pipe 33 and the heat transfer pipe 32 to facilitate the passage of the refrigerant.

[0024] The compressor 4 and the expansion valve 5 are distributed in a mirror image on the upper end of the bottom plate 1, and the structure is beautiful and the design is reasonable.

[0025] The heat dissipation pipe 61 is spiral, so that the high-temperature refrigerant releases heat over a wider area and has a better heat release effect.

[0026] Embodiment 2: Figure 4 As shown, the outer surface of the heat transfer tube 32 is sleeved with a recovery tube 8, one end of the recovery tube 8 is interspersed with a main heat column 81 and two auxiliary heat columns 82, and a column groove 83 used for the auxiliary heat column 82 is opened on the lower side of one end of the recovery tube 8. The main heat column 81 and the auxiliary heat column 82 are both connected to the water tank 6, and the recovery tube 8 is sleeved on the outer surface of the heat transfer tube 32. Since high-temperature steam passes through the heat transfer tube 32, the recovery tube 8 can effectively absorb its heat, and then transfer the heat to the water tank 6 through the main heat column 81 and the auxiliary heat column 82, thereby reducing heat loss and increasing waste heat recovery efficiency.

[0027] The positions of the main heating column 81 and the auxiliary heating column 82 correspond to the position of the hot water outlet 63 . Before the hot water outlet 63 discharges hot water, the water can better absorb the temperature of the main heating column 81 and the auxiliary heating column 82 .

[0028] Working principle: water to be heated is stored in the water tank 6, refrigerant is placed in the heat transfer pipe 3, and the heat absorbing sheet 2 is placed next to the hot water pipe or the heating part of the machine to recover the waste heat. The heat in the air is transferred to the heat transfer pipe 3 through the heat absorbing sheet 2. When the refrigerant absorbs heat and changes from liquid to low-pressure gas, it enters the compressor 4 through the delivery pipe 35 and the output pipe 31. The compressor 4 increases the pressure and temperature of the gas, and then transfers it to the water tank 6 through the heat transfer pipe 32. The high-temperature and high-pressure gas passes through the water tank 6 through the heat dissipation pipe 61, and the hot gas releases heat to the water in the water tank 6, thereby achieving the effect that the cold water entering the cold water port 62 and the hot water port 63 output becomes hot water. When the heat of the refrigerant is released, the refrigerant changes from gas to high-pressure liquid. The low-temperature and high-pressure liquid refrigerant enters the expansion valve 5 through the cold pipe 33. The expansion valve 5 reduces its pressure and temperature, thereby becoming a normal liquid refrigerant. The liquid refrigerant then flows into the heat transfer pipe 3 through the return pipe 34, and the cycle is repeated. The structural design is simple and reasonable, and the heating effect of the heat pump is good.

[0029] The fan 71 on the accelerator plate 7 blows air toward the heat absorbing plate 2, thereby increasing the ability of the warm air to transfer heat to the refrigerant and improving the waste heat recovery efficiency;

[0030] The support block 64 improves the strength of the connection structure of the water tank 6, and the spiral heat dissipation pipe 61 allows the high-temperature refrigerant to release heat over a wider area, resulting in a better heat release effect;

[0031] The recovery pipe 8 is sleeved on the outer surface of the heat transfer pipe 32. Since the heat transfer pipe 32 passes high-temperature steam, the recovery pipe 8 can effectively absorb its heat and then transfer the heat to the water tank 6 through the main heat column 81 and the auxiliary heat column 82, thereby reducing heat loss and increasing waste heat recovery efficiency.

[0032] The positions of the main heating column 81 and the auxiliary heating column 82 correspond to the position of the hot water outlet 63 . Before the hot water outlet 63 discharges hot water, the water can better absorb the temperature of the main heating column 81 and the auxiliary heating column 82 .

[0033] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
