Technical Field
[0001] The utility model relates to the technical field of battery heat dissipation equipment, in particular to a battery cooling heat exchanger for new energy vehicles. Background Art
[0002] New energy batteries are very stable at room temperature and can provide a steady supply of electricity for new energy vehicles. New energy batteries can be charged and recycled for multiple times. However, new energy batteries become unstable in special environments, especially high temperature environments. New energy batteries generate heat during the charging and discharging process. If the heat generated cannot be discharged, it will accumulate and cause battery bulging or damage to key components. Continuous high heat of new energy batteries may also cause combustion, explosion, etc. Under normal circumstances, new energy batteries can solve the heat problem generated by charging and discharging through air cooling or air heat dissipation. However, when the charging input current and voltage become abnormally large in a short period of time, or the battery continues to discharge for a long time, the battery itself or the basic auxiliary heat dissipation equipment cannot cool the battery in time and effectively. At this time, the battery may be in a dangerous situation. Therefore, how to solve the above-mentioned problems has become a difficult problem that needs to be solved urgently. Utility Model Content
[0003] The utility model aims to provide a battery cooling heat exchanger for new energy vehicles which can be rolled into a tubular structure to perform heat exchange on cylindrical batteries, or can be directly attached to the outer wall of a block battery to perform heat exchange.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a battery cooling heat exchanger for new energy vehicles, comprising a flexible heat exchanger panel, a heat dissipation and heat conduction air pipe and a heat dissipation and flow-guiding circulating water pipe are arranged on the inner side of the flexible heat exchanger panel, an air outlet port is arranged on one side of the flexible heat exchanger panel, and an air-cooling heat exchange drive is connected to the other side of the flexible heat exchanger panel through the air inlet port, and the water inlet and outlet ports of the heat dissipation and flow-guiding circulating water pipe extend to the outside of the flexible heat exchanger panel, the water inlet and outlet ports are connected to a pump pressure circulation drive, and a cooling circulation water storage tank is connected to one side of the pump pressure circulation drive.
[0005] Preferably, a contact thermal adsorption coating is provided on the side of the flexible panel of the heat exchanger, and a winding locking buckle is provided on the side of the contact thermal adsorption coating.
[0006] Preferably, a drainage air inlet elbow is provided on one side of the air-cooling heat exchange drive, and a diversion air inlet and outlet port is provided on the other side of the air-cooling heat exchange drive.
[0007] Preferably, a pump pressure protection cover is provided on the outside of the pump pressure circulation drive, an auxiliary circulation drive is provided on the side of the pump pressure circulation drive, and the output end of the auxiliary circulation drive is respectively connected to the water inlet and outlet ports and the cooling circulation water tank.
[0008] A water tank circulation drive is provided on one side of the cooling circulation water storage tank, and the water tank circulation drive is connected to the water inlet and outlet ports through a conduit.
[0009] Compared with the prior art, the beneficial effects of the utility model are:
[0010] (1) The utility model can be rolled into a tubular structure to perform heat exchange on cylindrical batteries, or can be directly attached to the outer wall of block batteries for heat exchange. The device has both air and fluid heat dissipation methods. The air heat dissipation can be connected to the inside of the battery shell to cool the battery by directly extracting the internal hot air or introducing cold air. Air heat dissipation and fluid heat dissipation can be performed separately or simultaneously.
[0011] (2) The flexible panel of the heat exchanger can be rolled into a tubular structure or unfolded into a flat structure. The technical problem of battery heat dissipation can be solved by increasing the contact surface with the battery. Flowing air or fluid has better heat dissipation effect than natural heat dissipation. When the intake elbow is connected to the inside of the battery box, the split inlet and outlet ports can directly discharge the hot air or discharge it through the heat dissipation air pipe. (3) The pump pressure circulation drive and the auxiliary circulation drive can be used together to realize the rapid circulation of cooling water. When one of the above two sets of equipment is damaged, the water tank circulation drive can be quickly replaced through the solenoid valve and the conduit to solve the problem of insufficient water circulation kinetic energy.
