Description

Technical Field

[0001] The utility model relates to the technical field of new energy, and in particular to a whole vehicle cooling device and whole vehicle equipment. Background Art

[0002] New energy vehicles need to transport coolant from the front end to the rear end for cooling the rear end motor and cockpit, etc., and nylon tubes or steel pipes are usually used as coolant carriers; since the power battery pack is usually arranged under the floor of the vehicle body, the cooling pipes on the vehicle can only be arranged on both sides of the battery pack or above the battery pack. If it is above the battery pack, a raised structure is required on the floor for the layout of the cooling pipes.

[0003] If the cooling pipes are arranged on both sides of the battery pack, they will occupy the space of the vehicle's door sill beam or the battery pack beam system. On the one hand, this will weaken the vehicle's pillar impact strength. On the other hand, the water cooling pipes are usually fixed to the door sill beam with clips. To prevent the cooling pipes from interfering with the battery pack, causing wear, rupture and abnormal noise, sufficient clearance must be left between the cooling pipes and the battery pack.

[0004] If the cooling pipe is arranged above the battery pack, the floor needs to be raised to leave space for the cooling pipe, and it needs to be fixed to the floor with clips. The raised floor structure will reduce the effective height of the vehicle's crossbeam and the strength of the vehicle's column collision structure. Utility Model Content

[0005] Based on the technical problems existing in the background technology, the utility model proposes a whole vehicle cooling device and a whole vehicle equipment, which solves the problem of the layout space of the cooling pipeline passing through the battery pack, and indirectly enhances the pillar impact strength of the whole vehicle.

[0006] The utility model proposes a whole vehicle cooling device, in which a cooling assembly is arranged on an outer frame of a power battery pack, wherein the cooling assembly comprises a hollow channel plate, both ends of the channel plate are connected to an external water cooling pipe through a pipe assembly respectively, and the channel plate and the outer frame of the power battery pack are integrally formed.

[0007] Furthermore, two channel plates are arranged in parallel on two sides of the outer frame.

[0008] Furthermore, the pipe assembly includes a water-cooling joint and an external water pipe, and the end of the channel plate is connected to one end of the external water pipe through the water-cooling joint.

[0009] Furthermore, one end of the water-cooling joint is threaded, the inner channel of the channel plate is threaded, and the water-cooling joint is threadedly connected to the channel plate;

[0010] The other end of the water-cooling joint is provided with an inverted structure for quick connection with a matching structure provided on an external water pipe.

[0011] Furthermore, the outer frame of the power battery pack is made of aluminum profiles. During the molding of the outer frame of the power battery pack, the channel plate is extruded by extruding the aluminum profiles.

[0012] Furthermore, waterproof glue is applied to the water cooling joint to ensure the air tightness of the connection.

[0013] A whole vehicle device comprises a vehicle body and a cooling device for cooling a motor or a cabin in the vehicle body, wherein the cooling device corresponds to the above-mentioned whole vehicle cooling device.

[0014] The advantages of the whole vehicle cooling device and whole vehicle equipment provided by the utility model are: the whole vehicle cooling device and whole vehicle equipment provided in the utility model structure integrate the channel plate in the cooling assembly on the outer frame of the power battery pack, and use the beam (outer frame) structure as a coolant carrier, which plays a certain role in weight reduction.

[0020] Below, the technical solution of the utility model is described in detail through specific embodiments. Many specific details are described in the following description to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific implementation disclosed below.

[0021] like Figures 1 to 4As shown, the utility model proposes a vehicle cooling device, in which a cooling assembly 2 is arranged on an outer frame 1 of a power battery pack, wherein the cooling assembly 2 includes a hollow channel plate 21, and both ends of the channel plate 21 are connected to an external water cooling pipe through a pipe assembly 22 respectively, and the channel plate 21 is integrally formed with the outer frame 1 of the power battery pack.

[0022] New energy vehicles need to transport the front-end coolant to the rear end for cooling the rear-end motor and cockpit, etc., and nylon tubes or steel tubes are usually selected as coolant carriers. Traditionally, an additional coolant carrier is provided. The additional carrier does not cooperate well with the power battery pack, which can easily cause a series of structural defects. This embodiment solves the problem of the cooling pipeline layout space passing through the power battery pack by integrally forming a cooling assembly 2 on the outer frame 1 of the power battery pack; reduces the length of the cooling pipeline and reduces the clips used to fix the cooling pipeline; indirectly enhances the pillar impact strength of the entire vehicle.

[0023] In this embodiment, the pipe assembly 22 includes a water-cooling joint 23 and an external water pipe 24 , and an end of the channel plate 21 is connected to one end of the external water pipe 24 through the water-cooling joint 23 .

[0024] One end of the water-cooling joint 23 is threaded, the inner channel of the channel plate 21 is threaded, and the water-cooling joint 23 is threadedly connected to the channel plate 21; the other end of the water-cooling joint 23 is provided with an inverted structure, which is quickly connected to the matching structure provided on the external water pipe 24; the water-cooling joint 23 with a thread acts as a bolt and is connected to the channel plate 21, thereby realizing a quick-release connection between the integrally formed channel plate 21 and the external water pipe 24.

[0025] The channel plate 21 in the cooling assembly 2 is integrated on the outer frame 1 of the power battery pack, and the beam (outer frame 1) structure is used as a coolant carrier, which plays a certain role in weight reduction. In addition, the water cooling joint in the cooling assembly 2 and the external water pipe 24 adopt a quick-plug structure to save assembly time.

[0026] Moreover, the outer frame 1 of the power battery pack is made of aluminum profile. During the molding of the outer frame 1 of the power battery pack, the channel plate 21 is extruded by extruding the aluminum profile. The molding process is simple, and the aluminum profile has good heat dissipation, thereby improving the cooling efficiency of the cooling assembly 2 for the entire vehicle.

[0027] It is understandable that this embodiment is a water-cooling arrangement, and therefore waterproof glue is applied to the water-cooling joint 23 to ensure the airtightness of the connection.

[0028] In addition, two channel plates 21 are arranged in parallel on both sides of the outer frame 1 to evenly cool the entire vehicle structure and avoid structural defects caused by local overheating.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
