It is to be understood that the embodiments described are only a few embodiments of the present specification, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from the embodiments given herein without making any creative effort fall within the scope of protection of one or more embodiments of the present specification.

At present, a plurality of batteries are connected in series or in parallel to form a battery pack. During the driving process of the new energy automobile, the heat emitted by the battery can be accumulated. In the prior art, the battery heat dissipation device needs the vehicle-mounted battery to provide electric power, so that the heat accumulation of the battery is more obvious in the initial stage of the use of the battery heat dissipation device.

In order to solve the technical problem, as shown in fig. 1, an embodiment of the utility model provides a cooling system for new energy automobile, include: a battery holder 10, the battery holder 10 providing a space in which a plurality of vehicle-mounted batteries 101 are placed; and a plurality of radiators 20, the plurality of radiators 20 being disposed between the vehicle-mounted batteries 101 so as to surround at least two radiators 20 between the vehicle-mounted batteries 101; and a temperature sensor 30, the temperature sensor 30 being provided at the bottom of the vehicle-mounted battery 101, for detecting the temperature of the vehicle-mounted battery 101; a controller 40 electrically connected to the temperature sensor 30 for controlling the opening and closing of the heat sink 20 according to the temperature monitored by the temperature sensor 30; and the special battery pack 50 is arranged at the bottom of the new energy automobile and is far away from the battery rack 10, and is used for supplying power to the temperature sensor 30, the radiator 20 and the controller 40.

Since the vehicle-mounted battery 101 of the new energy automobile is composed of a plurality of vehicle-mounted batteries 101 stacked in series, the battery rack 10 provides a space for placing the plurality of vehicle-mounted batteries 101 so that the vehicle-mounted batteries 101 can be placed in a predetermined arrangement. The battery holder 10 has a space for accommodating the vehicle-mounted battery 101 and is adapted to the shape of the vehicle-mounted battery 101. For example: as shown in fig. 2, when the vehicle-mounted battery 101 is a rectangular parallelepiped, the carrying space of the battery rack 10 is an arrangement of a plurality of rectangular arrays. As shown in fig. 3, when the vehicle-mounted battery 101 is cylindrical, the load-bearing space of the battery rack 10 is arranged in a honeycomb shape.

The temperature sensor 30 is provided at the bottom of the vehicle-mounted battery 101 for detecting the temperature of the vehicle-mounted battery 101. Since the bottom of the vehicle-mounted battery 101 is where the most heat is accumulated, disposing the temperature sensor 30 at the bottom of the vehicle-mounted battery 101 is more advantageous for detecting the temperature of the vehicle-mounted battery 101. The temperature sensor 30 is one or more. When the number of the temperature sensors 30 is 1, it is disposed in the center of the vehicle-mounted battery 101; when the temperature sensor 30 is plural, it may be provided at different positions of the vehicle-mounted battery 101. When the temperature of any one of the vehicle-mounted batteries 101 is higher than a preset threshold, the radiator 20 is activated. When the temperature of the vehicle-mounted battery 101 therein is all lower than the preset threshold, the radiator 20 is turned off.

When the temperature monitored by the temperature sensor 30 is higher than the preset threshold, the controller 40 sends a control command to the radiator 20, and the radiator 20 is turned on to cool the vehicle-mounted battery 101. The radiator 20 can cool the vehicle-mounted battery 101 by forced air convection. The plurality of radiators 20 are distributed in the gap of the battery, so that at least two radiators 20 are arranged around each vehicle-mounted battery 101, and when the number of radiators 20 around each vehicle-mounted battery 101 is 2, the two radiators 20 are respectively arranged on two sides of the vehicle-mounted battery 101, and the vehicle-mounted battery 101 can be radiated to the maximum extent. When the number of the radiators 20 is plural, the plural radiators 20 are evenly distributed around the vehicle-mounted battery 101.

When the temperature of the vehicle-mounted battery 101 is high, the radiator 20 needs to be started to radiate the heat of the vehicle-mounted battery 101, and the initial stage of the use of the battery radiating device can cause the heat accumulation of the vehicle-mounted battery 101 to be more obvious because the radiator 20 needs to consume electric energy when being started. Therefore, in the embodiment of the present specification, the special battery pack 50 is provided to supply power to the temperature sensor 30, the radiator 20 and the controller 40, and the special battery pack 50 is provided at the bottom of the new energy vehicle, away from the battery rack 10, so as to ensure that the temperature of the vehicle-mounted battery 101 is not affected by the heat emitted by the special battery pack 50 during use.

The heat dissipation system for the new energy automobile provided by the embodiment of the specification is provided with the special battery pack 50, so that sufficient power supplies for the temperature sensor, the controller 40 and the radiator 20 can be ensured, the special battery pack 50 is arranged at the bottom of the new energy automobile far away from the vehicle-mounted battery 101, and the temperature rise of the vehicle-mounted battery 101 of the radiator 20 in the initial working period is ensured. The utility model discloses a special battery group 50 has both guaranteed new energy automobile's heat dissipation, can not increase vehicle-mounted battery 101's burden again.

In an alternative embodiment, the radiator 20 of the present embodiment is a radiating pipe with multiple rows of radiating holes. That is, the radiating pipe is provided with a plurality of through holes so that the wind passes through the radiating pipe to take away the heat radiated from the vehicle-mounted battery 101. The radiating pipe is made of insulating heat-resistant material. The multiple rows of heat dissipation holes are arranged and distributed according to a preset rule. For example: the heat dissipation holes are distributed in a matrix.

According to a further optimized scheme, at least two radiators 20 are encircled between the vehicle-mounted batteries 101, and the method specifically comprises the following steps: the included angle between the two radiating pipes and the axis of the electric core of the surrounding vehicle-mounted battery 101 is 180 degrees. A plurality of radiators 20 may be provided between adjacent vehicle-mounted batteries 101, i.e., a plurality of radiators 20 may be provided around each vehicle-mounted battery 101. For example: the number of the radiators 20 is 4, the radiators 20 are evenly distributed around the vehicle-mounted battery 101.

In a further optimized scheme, as shown in fig. 4, the heat dissipation system for the new energy vehicle further includes: a fan 60 electrically connected to the controller 40 and the heat sink 20 for supplying air to the heat sink 20; the controller 40 controls the on/off of the fan 60 according to the temperature monitored by the temperature sensor 30.

The controller 40 controls the fan 60 to be turned on or off according to data monitored by the sensor. When the temperature monitored by the temperature sensor 30 is higher than a first preset threshold, the fan 60 is turned on; when the temperature monitored by the temperature sensor 30 is below a first preset threshold, the fan 60 is turned off. The first preset threshold value is different according to the model of the new energy automobile.

Typically, the first predetermined threshold is 45 degrees celsius. When the temperature of the vehicle-mounted battery 101 monitored by the temperature sensor 30 is higher than a first preset threshold, the controller 40 sends a first driving instruction to the fan 60, the first driving instruction being used to start the fan 60. When the temperature of the vehicle-mounted battery 101 monitored by the temperature sensor 30 is lower than a first preset threshold, the controller 40 sends a second drive instruction to the fan 60, the second drive instruction being for turning off the fan 60.

In a further preferred embodiment, when the temperature monitored by the temperature sensor 30 is higher than a first preset threshold, the fan 60 is turned on, which includes: the fan 60 provides different air volumes according to different temperatures monitored by the temperature sensor 30. For example: the air output of the fan 60 at a temperature of 48 degrees celsius monitored by the temperature sensor 30 is lower than the air output of the fan 60 at a temperature of 52 degrees celsius monitored by the temperature sensor 30.

The utility model discloses technical scheme is through the temperature at temperature sensor 30 monitoring vehicle battery 101 to through opening and closing of controller 40 control radiator 20, can make vehicle battery 101 open radiator 20 and dispel the heat to vehicle battery 101 when the temperature surpasss the threshold value, avoid vehicle battery 101 overheated influence life. In addition, since the temperature sensor 30, the controller 40, and the radiator 20 are all supplied with power by the dedicated battery pack 50, temperature rise in a short time due to turning on of the elements such as the radiator 20 when the in-vehicle battery 101 is overheated is avoided. Meanwhile, as the special battery pack 50 is arranged at the bottom of the new energy automobile and is far away from the vehicle-mounted battery 101 rack 10, the heat generated by the special battery pack 50 can be ensured to the maximum extent not to influence the temperature of the vehicle-mounted battery 101.
