Description

Technical Field

[0001] This utility model relates to the field of waste heat recovery technology for electric vehicles, and in particular to a waste heat recovery device for electric vehicles. Background Technology

[0002] Electric vehicles (EVs) are vehicles powered by an onboard power source, using an electric motor to drive the wheels, and meeting all road traffic and safety regulations. They employ battery packs as energy storage devices, converting electrical energy into mechanical energy through an electric motor to propel the vehicle. Electric motors offer advantages such as high efficiency, low noise, and low vibration, providing instant torque output and giving the vehicle good acceleration performance. Energy is primarily replenished by charging the battery through charging facilities. During operation, electric vehicles require waste heat recovery devices to recover and reuse the heat generated by the battery.

[0003] Existing waste heat recovery devices for electric vehicles often use a single heat exchanger to convert the heat energy generated by the battery during operation. However, this heat exchange requires the circulation of coolant to convert the heat, which is relatively complex and occupies a large space. It is not convenient to recycle and reuse the heat generated by the electric vehicle battery in a stable and quick manner. As a result, it is impossible to quickly capture and transfer the heat generated by the battery, causing a large amount of valuable heat to be lost. It is not convenient to efficiently convert it into a reusable form of energy, making it difficult to meet the urgent needs of practical application scenarios for efficient and stable recovery of battery waste heat. Utility Model Content

[0004] The purpose of this invention is to provide a waste heat recovery device for electric vehicles, which solves the shortcomings of existing waste heat recovery devices for electric vehicles that are inconvenient, unstable and quick to recover and reuse the heat generated by the operation of electric vehicle batteries.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a waste heat recovery device for electric vehicles, including a battery placement base;

[0006] A battery module is installed inside the battery placement base, and a waste heat recovery mechanism is installed inside the battery placement base;

[0007] The waste heat recovery mechanism includes a positioning groove inside the battery placement seat, a heat-conducting plate installed inside the positioning groove, a heat exchange tube installed on the inner wall of the heat-conducting plate, a baffle plate fixedly connected inside the heat exchange tube, a fan fixedly connected to one end of the heat exchange tube, and an air outlet pipe fixedly connected to one side of the fan.

[0008] Preferably, the spoiler has a first through hole inside and a second through hole inside.

[0009] Preferably, the first through holes are evenly distributed along the inner wall of the heat exchange tube, and the second through holes are arranged in a ring around the central axis of the first through holes.

[0010] Preferably, the battery placement seat is engaged with the heat-conducting plate via a positioning groove. The heat-conducting plate has an open design and a T-shaped configuration. The heat-conducting plate is welded to the heat exchange tube.

[0011] Preferably, a sealing tube is fixedly connected to one end of the air outlet pipe, a retaining ring is fixedly connected to the outer wall of the air outlet pipe, a positioning sleeve is installed on the outer wall of the air outlet pipe, a threaded groove is opened inside the positioning sleeve, and an air conditioning duct is installed at one end of the air outlet pipe.

[0012] Preferably, the air outlet pipe is movably connected to the positioning sleeve, and the air outlet pipe is connected to the air conditioning duct via a sealing insert.

[0013] Preferably, the outer wall of the air conditioning duct is provided with threads, and the air conditioning duct is threadedly connected to the positioning sleeve through a threaded groove.

[0014] The present invention provides a waste heat recovery device for electric vehicles, which has the following advantages:

[0015] By setting up battery modules and waste heat recovery mechanisms, the heat generated during the operation of the battery modules is discharged through the battery modules and introduced into the heat exchange tubes through the heat conduction plate. When the fan is started, the air flowing through the heat exchange tubes is heated, which can easily and quickly recover and reuse the heat generated by the operation of the battery modules, and to a certain extent prevent the battery modules from having their service life affected by excessive temperature.

[0016] Furthermore, the multiple baffles slow down the airflow as it passes through the heat exchange tubes, thus improving the efficiency of heat conduction between the air and the heat exchange tubes.

[0017] Furthermore, the combined effect of the first and second through holes can increase the contact area between the air and the baffle, allowing the air to carry away the heat from the heat exchange tube, thereby further improving the efficiency of recovering and reusing the heat generated by the battery module.

[0018] By using the battery module, air outlet duct, sealing tube, retaining ring, positioning sleeve and air conditioning duct, the sealing tube is inserted into the air conditioning duct by moving the air conditioning duct, so that the air outlet duct and the air conditioning duct are connected. This allows the converted hot air to be delivered to the car's air conditioning system, which can recover the heat generated by the battery module for auxiliary heating of the car interior.

[0019] Furthermore, by connecting the positioning sleeve to the end of the air conditioning duct and rotating it, the positioning sleeve can be tightened around the air outlet duct and the air conditioning duct under the action of the retaining ring, which facilitates the connection and assembly of the air outlet duct and the air conditioning duct.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0028] Please see Figures 1-6 The present invention provides a waste heat recovery device for electric vehicles, including a battery placement seat 1.

[0029] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a battery module 2 is installed inside the battery placement base 1, and a waste heat recovery mechanism 3 is installed inside the battery placement base 1. The waste heat recovery mechanism 3 includes a positioning groove 31 opened inside the battery placement base 1, a heat-conducting plate 32 is installed inside the positioning groove 31, a heat exchange tube 33 is installed on the inner wall of the heat-conducting plate 32, a baffle plate 34 is fixedly connected inside the heat exchange tube 33, a fan 37 is fixedly connected to one end of the heat exchange tube 33, and an air outlet pipe 38 is fixedly connected to one side of the fan 37. A first through hole 35 is opened inside the baffle plate 34, and a second through hole 36 is opened inside the baffle plate 34. The first through holes 35 are evenly distributed on the inner wall of the heat exchange tube 33, and the second through holes 36 are arranged in a ring around the central axis of the first through holes 35. The battery placement base 1 is engaged with the heat-conducting plate 32 through the positioning groove 31. The heat-conducting plate 32 is an open-hole design and is T-shaped. The heat-conducting plate 32 is welded to the heat exchange tube 33.

[0030] By snapping multiple heat-conducting plates 32 into the positioning groove 31, the battery module 2 is placed in the battery placement seat 1. When the battery module 2 is running, it will generate heat. Since one side of the multiple heat-conducting plates 32 is in contact with the outer wall of the battery module 2, the heat on the battery module 2 can be discharged. Since the heat-conducting plates 32 are welded to the heat exchange tubes 33, the heat can be introduced into the heat exchange tubes 33 through the heat-conducting plates 32. When the fan 37 is started, air can be drawn in from one end of the heat exchange tubes 33. When the air flows through the heat exchange tubes 33, it is heated under the turbulence of the baffle 34, so that the hot air is transported through the first through hole 35 and the second through hole 36, and finally transported to the air outlet duct 38 by the fan 37 and discharged from one end of the air outlet duct 38.

[0031] Reference Figure 1 and Figure 6 As shown, a sealing tube 4 is fixedly connected to one end of the air outlet duct 38, a retaining ring 5 is fixedly connected to the outer wall of the air outlet duct 38, a positioning sleeve 6 is installed on the outer wall of the air outlet duct 38, a threaded groove 7 is opened inside the positioning sleeve 6, an air conditioning duct 8 is installed at one end of the air outlet duct 38, the air outlet duct 38 is movably connected to the positioning sleeve 6, the air outlet duct 38 is engaged with the air conditioning duct 8 through the sealing tube 4, the outer wall of the air conditioning duct 8 is provided with threads, and the air conditioning duct 8 is threadedly connected to the positioning sleeve 6 through the threaded groove 7.

[0032] By moving the air conditioning duct 8 to align with one end of the air outlet duct 38, the sealing tube 4 is inserted into the air conditioning duct 8 for sealing. The positioning sleeve 6 is pulled to slide along the air outlet duct 38. When the positioning sleeve 6 aligns with the end of the air conditioning duct 8, the positioning sleeve 6 is rotated. Since the positioning sleeve 6 is threadedly connected to the air conditioning duct 8 through the threaded groove 7, the positioning sleeve 6 can tighten the air outlet duct 38 and the air conditioning duct 8 under the action of the retaining ring 5, thereby aligning and assembling the air outlet duct 38 and the air conditioning duct 8, so that hot air is delivered to the air conditioning system through the air conditioning duct 8 for auxiliary heating of the vehicle interior.
