Description

Technical Field

[0001] The present invention belongs to the technical field of electric vehicles, and specifically discloses a dual-source heat pump applicable to electric vehicles. Background Art

[0002] The dual-source heat pump of an electric vehicle is an efficient air-conditioning system that can significantly reduce energy consumption and increase the cruising range. The core of the dual-source heat pump technology lies in its ability to utilize multiple heat sources to meet the cooling and heating requirements of electric vehicles. This technology combines two modules: a direct heat pump and an indirect heat pump. The direct heat pump is mainly used for heating the vehicle cabin, and can quickly increase the temperature inside the vehicle through an efficient refrigerant cycle; while the indirect heat pump takes into account the heating requirements of both the cabin and the battery, and uses a coolant to conduct heat. In addition, the dual-source heat pump may also combine multiple heat sources such as the waste heat of an electric drive resistance conversion air-conditioning compressor and PTC heating, and optimize the battery heating speed and efficiency through synergistic effects.

[0003] In the past, for the dual-source heat pump applicable to electric vehicles, most current electric vehicles adopt hidden door handles. In winter, the door handles of electric vehicles are prone to freezing. In the past, electric vehicles used a dual-source heat pump to heat the interior of the vehicle, thereby thawing the door handles. However, using the dual-source heat pump heating method requires a long time to heat the interior of the vehicle, which in turn causes the heating element to consume too much heat energy, affecting the cruising range of the electric vehicle and wasting energy. Summary of the Invention

[0007] In the above technical solution, preferably, a fixing rod is fixedly connected to the inner top of the collection bin. A flow disturbing block is fixedly connected to the rear end of the fixing rod. A main flow disturbing plate is fixedly connected to the outer side of the flow disturbing block.

[0008] In the above technical solution, preferably, a mounting ring is fixedly connected to the inside of the air outlet frame. A connecting rod is fixedly connected to the inside of the mounting ring. One end of the connecting rod is fixedly connected with a flow pushing block. A flow splitting plate is fixedly connected to the inner bottom of the air outlet bin. The shape of the flow splitting plate is triangular. There are multiple groups of the flow splitting plates. The widths of the multiple groups of flow splitting plates are different, and the multiple groups of flow splitting plates are narrower and narrower as they are closer to the connecting rod.

[0009] In the above technical solution, preferably, the shape of the communication bin is frustum-shaped. The material of the flow splitting pipe is copper, and the shape layout of the flow splitting pipe can be adjusted according to the vehicle body. The shape of the flow disturbing block is frustum-shaped. The shapes of the main flow disturbing plate and the secondary flow disturbing plate are both wavy, and the main flow disturbing plate is larger than the secondary flow disturbing plate.

[0010] In the above technical solution, preferably, there are several groups of both the main flow disturbing plates and the secondary flow disturbing plates. And between several groups of the main flow disturbing plates and the secondary flow disturbing plates, they are sequentially distributed in a fan shape on the outer side of the flow disturbing block.

[0011] In the above technical solution, preferably, there is a gap between the flow disturbing block and the collection bin. The shape of the flow pushing block is frustum-shaped, and the smaller diameter end of the flow pushing block corresponds to the flow splitting pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] When the hot air contacts the spoiler blocks, the main spoiler plate and the secondary spoiler plate rotate and disperse the hot air. After the hot air contacts the spiral frame, the rotation and flow speed of the hot air are accelerated, which can achieve the purpose of facilitating the rapid flow of the hot air and changing the smooth flow form of the hot air to make it flow rapidly.

[0016] When the hot air blows onto the pusher block, the pusher block disperses the hot air around by virtue of its own shape, and the hot air contacts a number of component flow splitting plates, and the widths of the flow splitting plates gradually change, so that the number of component flow splitting plates evenly disperses the hot air, which can achieve the purpose of facilitating the uniform and large-area outward flow of the hot air from the air outlet frame, so that the hot air blows onto the door handle, and the hot air precisely heats the door handle to quickly defrost the door handle.

[0017] Moreover, the hot air is rotationally dispersed by the main spoiler plate and the secondary spoiler plate to form multiple air paths for winding flow. After contacting the spiral frame, the rotation and flow speed of the hot air are accelerated, so that the heat of the hot air is maximally insulated, and a number of component flow splitting plates evenly disperse the hot air, so that the hot air in insulation quickly dissipates heat outward, thereby accelerating the heating of the door handle.

[0032] The flow splitting mechanism 7 includes a fixing plate 71 fixedly connected to the rear end of the in-vehicle condenser 1. An air permeation groove 72 is formed inside the fixing plate 71. The lower end of the fixing plate 71 is fixedly connected with a mounting frame 73. A connecting block 74 is fixedly connected to the inner wall of the mounting frame 73. One end of the connecting block 74 is fixedly connected with a collection bin 75. The rear end of the collection bin 75 is fixedly connected with a communication bin 76. A control valve 77 is installed at the rear end of the communication bin 76. A flow splitting pipe 78 is installed at the rear end of the control valve 77. One end of the flow splitting pipe 78 is fixedly connected with an air outlet bin 79. A fixing rod 710 is fixedly connected to the inner top of the collection bin 75. The rear end of the fixing rod 710 is fixedly connected with a flow disturbing block 711. A main flow disturbing plate 712 is fixedly connected to the outer side of the flow disturbing block 711. A secondary flow disturbing plate 713 is fixedly connected to the side of the outer side of the flow disturbing block 711 close to the main flow disturbing plate 712. A spiral frame 714 is fixedly connected to the inner wall of the communication bin 76. An air outlet frame 715 is fixedly connected to the inside of the air outlet bin 79. A mounting ring 716 is fixedly connected to the inside of the air outlet frame 715. A connecting rod 717 is fixedly connected to the inside of the mounting ring 716. One end of the connecting rod 717 is fixedly connected with a flow pushing block 718. A flow splitting plate 719 is fixedly connected to the inner bottom of the air outlet bin 79. The shape of the flow splitting plate 719 is triangular. There are multiple groups of the flow splitting plates 719. The widths of the multiple groups of flow splitting plates 719 are different, and the multiple groups of flow splitting plates 719 are narrower the closer they are to the connecting rod 717. The shape of the communication bin 76 is frustum-shaped. The material of the flow splitting pipe 78 is copper, and the shape layout of the flow splitting pipe 78 can be adjusted according to the vehicle body. The shape of the flow disturbing block 711 is frustum-shaped. The shapes of the main flow disturbing plate 712 and the secondary flow disturbing plate 713 are both wavy, and the main flow disturbing plate 712 is larger than the secondary flow disturbing plate 713. The numbers of the main flow disturbing plate 712 and the secondary flow disturbing plate 713 are both several groups, and the several groups of the main flow disturbing plate 712 and the secondary flow disturbing plate 713 are sequentially distributed in a fan shape on the outer side of the flow disturbing block 711. The spiral frame 714 is closely attached to the inner wall of the communication bin 76. The inner diameter of the spiral frame 714 is slightly larger than the outer diameter of the flow disturbing block 711. There is a gap between the flow disturbing block 711 and the collection bin 75. The shape of the flow pushing block 718 is frustum-shaped. The smaller diameter end of the flow pushing block 718 corresponds to the flow splitting pipe 78.

[0033] During use, hot air is passed through the fixing plate 71, and the hot air passes through the ventilation slots 72, so that the fixing plate 71 reduces the amount of hot air blocked from entering the vehicle, and the hot air enters the collection bin 75. When the hot air contacts the spoiler block 711, the hot air passes through the main spoiler plate 712 and the secondary spoiler plate 713. The shapes of the main spoiler plate 712 and the secondary spoiler plate 713 are wavy. When the hot air passes through the spoiler block 711, rotational dispersion is formed, and the hot air flows into the communication bin 76. Then the hot air contacts the spiral frame 714, and the spiral frame 714 accelerates the rotation of the hot air by virtue of its shape, so that the hot air quickly flows forward. By the hot air contacting the spoiler block 711, the main spoiler plate 712 and the secondary spoiler plate 713 perform rotational dispersion treatment on the hot air. After the hot air contacts the spiral frame 714, the rotation flow speed of the hot air is accelerated, which can achieve the purpose of facilitating the rapid flow of the hot air, and change the form of the smooth flow of the hot air to make it flow quickly. At this time, the hot air flows into the air outlet bin 79 through the shunt pipe 78, and the push flow block 718 disperses the hot air around. At the same time, the hot air contacts the shunt plate 719. Since the width of the shunt plate 719 gradually changes, several shunt plates 719 evenly disperse the hot air, so that the hot air flows out uniformly and over a large area from the air outlet frame 715, and then the hot air blows on the door handle, so that the hot air precisely heats the door handle and quickly defrosts the door handle. By the hot air blowing on the push flow block 718, the push flow block 718 disperses the hot air around by virtue of its own shape, and the hot air contacts several shunt plates 719, and the width of the shunt plate 719 gradually changes, so that several shunt plates 719 evenly disperse the hot air, which can achieve the purpose of facilitating the uniform and large-area flow of the hot air from the air outlet frame 715 to the outside, so that the hot air blows on the door handle, so that the hot air precisely heats the door handle and quickly defrosts the door handle. And the hot air is subjected to rotational dispersion treatment by the main spoiler plate 712 and the secondary spoiler plate 713 to form multiple air paths for winding flow. After contacting the spiral frame 714, the rotation flow speed of the hot air is accelerated, so that the heat of the hot air is maximally insulated. And several shunt plates 719 evenly disperse the hot air, so that the hot air in insulation quickly dissipates heat to the outside, thereby accelerating the heating of the door handle.

[0034] The shape of the first pipe 3 is a three-way pipe. The rear end of the first expansion valve 9 is installed at the front end of the dryer 4. One end of the fifth pipe 12 is installed at one end of the in-vehicle condenser 1. The shape of the fifth pipe 12 is a three-way pipe. One end of the sixth pipe 14 is installed at the other end of the out-of-vehicle condenser 6. The main materials of the first pipe 3, the second pipe 5, the third pipe 8, the fourth pipe 10, the fifth pipe 12, and the sixth pipe 14 are all copper, and the shape layouts of the first pipe 3, the second pipe 5, the third pipe 8, the fourth pipe 10, the fifth pipe 12, and the sixth pipe 14 can all be adjusted according to the chassis.

[0035] By installing a fan at the front end of the evaporator 2 and installing the air outlet chamber 79 beside the door handle, starting the compressor 11, the compressor 11 heats the in-vehicle condenser 1 through the fifth pipe 12, and the fan at the front end of the evaporator 2 blows air on the evaporator 2 and the in-vehicle condenser 1, so that the air forms hot air after passing through the in-vehicle condenser 1.

[0036] Working principle: First, install a fan at the front end of the evaporator 2 and install the air outlet chamber 79 beside the door handle. Start the compressor 11, so that the compressor 11 heats the in-vehicle condenser 1 through the fifth pipe 12. The fan at the front end of the evaporator 2 blows air on the evaporator 2 and the in-vehicle condenser 1, so that the air forms hot air after passing through the in-vehicle condenser 1. Then the hot air passes through the fixing plate 71 and permeates through the air permeation slots 72, so that the fixing plate 71 reduces the amount of air blocking the hot air from entering the vehicle, and the hot air enters the collection chamber 75. The hot air contacts the flow disturbing block 711, and then passes through the main flow disturbing plate 712 and the secondary flow disturbing plate 713. The shapes of the main flow disturbing plate 712 and the secondary flow disturbing plate 713 are wavy. When the hot air passes through the flow disturbing block 711, it forms rotational dispersion, and the hot air flows into the communication chamber 76. Then the hot air contacts the spiral frame 714, and the spiral frame 714 accelerates the rotation of the hot air by virtue of its shape, so that the hot air quickly flows forward. By the hot air contacting the flow disturbing block 711, the main flow disturbing plate 712 and the secondary flow disturbing plate 713 perform rotational dispersion treatment on the hot air. After the hot air contacts the spiral frame 714, the rotation and flow speed of the hot air are accelerated, which can achieve the purpose of facilitating the rapid flow of the hot air, and change the form of the smooth flow of the hot air to make it flow rapidly. At this time, the hot air flows into the air outlet chamber 79 through the shunt pipe 78, and the flow pushing block 718 disperses the hot air around. At the same time, the hot air contacts the shunt plate 719. Since the width of the shunt plate 719 gradually changes, several shunt plates 719 disperse the hot air evenly, so that the hot air flows out evenly and over a large area from the air outlet frame 715, and then the hot air blows on the door handle, so that the hot air accurately heats the door handle and quickly defrosts the door handle. By the hot air blowing on the flow pushing block 718, the flow pushing block 718 disperses the hot air around by virtue of its own shape, and the hot air contacts several shunt plates 719, and the width of the shunt plate 719 gradually changes, so that several shunt plates 719 disperse the hot air evenly, which can achieve the purpose of facilitating the even and large-area outflow of the hot air from the air outlet frame 715. Then the hot air blows on the door handle, so that the hot air accurately heats the door handle and quickly defrosts the door handle. The hot air is subjected to rotational dispersion treatment by the main flow disturbing plate 712 and the secondary flow disturbing plate 713 to form multiple air paths for winding flow. After contacting the spiral frame 714, the rotation and flow speed of the hot air are accelerated, so that the heat of the hot air is maximally insulated. Several shunt plates 719 disperse the hot air evenly, so that the hot air in insulation quickly dissipates heat outward, thus accelerating the heating of the door handle.
