For example, the separation plate 212 may be fixed to the auxiliary tray 210 by rivets (not shown) provided separately.

The heat dissipation part provided in the present invention will be described with reference to FIG. 2 or FIG. 5.

The heat dissipation part 300 may be installed in close contact with the outer length of the tray 200, and may be disposed between the tray 200 and the tray 200.

The heat dissipation unit 300 may be installed on all sides except for the front, rear, and bottom surfaces of the tray 200.

The reason for this is to achieve high heat dissipation by receiving high temperature heat energy generated from the plurality of battery cells 10 and to facilitate ease of installation at the same time.

In addition, it is preferable that the heat dissipation part 300 uses a material having high thermal conductivity.

For example, aluminum copper may be used, but is not necessarily limited thereto.

Referring to FIG. 2, the heat dissipation unit 300 may be divided into the inside by the partition protrusions 312 along the length direction of the tray 200, and an inner region based on the partition protrusions 312. The first heat sink 300a partitioned to the lower side and the second heat sink 300b partitioned to the upper side are included.

That is, the heat dissipation unit 300 may be divided into upper and lower portions based on the longitudinal direction of the heat dissipation unit 300. .

In this embodiment, the partition projection 312 is shown in a rounded form toward the inner side from the left and right of the heat dissipation unit 300, respectively, but also changes to another structure that can partition the inner region of the heat dissipation unit 300 Make it possible.
The heat dissipation part 300 moves the coolant introduced into the first heat dissipation part 300a along the lower length direction of the heat dissipation part 300 and flows into the second heat dissipation part 300b positioned at an upper side thereof. The heat is radiated by conducting heat conducted from the battery cell 10 while moving along the upper longitudinal direction of the 300.

The heat dissipation unit 300 may further include a mounting unit 310 for mounting on the tray 200.

The mounting unit 310 may be provided at an upper side and a lower side in a length direction of the heat dissipation unit 300.

In addition, to be fixed to the tray 200, it may be riveted or joined by welding.

Referring to FIG. 3, an arrangement state of the base plate will be described.

The base plate 100 may be fixed to the lower portion of each tray 200 in a one-to-one correspondence. That is, it may be arranged independently of the lower portion of the tray 200 is arranged independently.

The base plate 100 and the tray 200 may be fixed to each other by riveting or welding.

Although not shown in the present embodiment, the base plate 100 may have a size capable of covering the entire tray 200.

The tray 200 may be assembled while the base plate 100 is fixedly installed on the lower bottom surface, and the heat dissipation unit 300 is fixedly coupled to both left and right sides.

Referring to FIG. 5, the heat dissipation unit 300 may be coupled to the inlet pipe 302 through which the coolant flows, and the outlet pipe 304 may be coupled to the top.

A plurality of trays 200 may be continuously arranged, and each tray 200 may be provided with an inlet pipe 302 and an outlet pipe 304.

In addition, in order to facilitate the work of the operator, the coupling pipe 306 and the inlet pipe 302 may be installed in the coupler.

The inlet pipe 302 and the outlet pipe 304 may be connected in parallel, in order to achieve uniform flow and heat dissipation of the coolant flowing in and out of the plurality of trays 200.

When the trays 200 are arranged in parallel, the coolant is supplied to each tray through the inlet pipe 302, and the high temperature coolant that is heat-exchanged with the battery cell 10 may be stably discharged to the outlet pipe 304. .

For example, when both the inlet pipe 302 and the outlet pipe 304 connected to the plurality of trays 200 are arranged in series, the flow of the cooling water may become uneven depending on the position, and the battery operated at high temperature. Since the cooling of the cell 10 is not made stable, it is preferable to arrange in parallel.

An operation state of the battery tray for an electric vehicle according to the present invention configured as described above will be described with reference to FIG. 6.

The plurality of trays 200 may be disposed in parallel in the vehicle, and may be fixed to the vehicle body while the bolts are coupled to holes provided in the base plate 100 (see FIG. 1).

Separation plates 212 are inserted into the grooves 211 provided in the auxiliary tray 210, respectively.

As described above, the separation plate 212 is bent portion 212a is riveted to the auxiliary tray 210, the fixed state is maintained.

The battery cells 10 are not all mounted in the inner region of the tray 200, and are inserted and mounted in the battery mounting area 201a and the battery cells 10 are mounted in the battery non-mounting area 201b for stable heat dissipation. I never do that.

As described above, when the electric vehicle is driven along the road in a state in which the mounting of the battery cell 10 is completed, electricity generated from the battery cell 10 is continuously supplied to a motor (not shown).

As the electric vehicle runs for a long time, high temperature heat energy is generated in the battery cell 10.

The coolant is supplied to the inner region of the heat dissipation unit 300 through the inlet pipe 302, and the coolant is moved along the length direction of the first heat dissipation plate 300a as shown by the dotted arrows in FIG. 2.

The coolant is transferred along the first heat sink 300a and conducts high temperature heat energy generated by the battery cell 10.

With reference to the accompanying Figure 7 will be described in more detail the heat dissipation state of the heat sink.

The battery cell 10 conducts high temperature thermal energy to the adjacent separator 212, the tray 200, and the heat dissipation part 300.

The high temperature heat energy generated by the battery cell 10 is illustrated by a thick arrow, and heat conduction is performed toward the heat dissipation part 300 located at the side surface.

The high temperature heat energy is conducted to the heat dissipation part 300 via the tray 200, and the heat exchange is performed while the coolant moving along the inside of the heat dissipation part 300 absorbs high temperature heat energy.

The cooling water maintains a relatively low temperature compared to the high temperature heat energy generated in the battery cell 10, and does not rapidly increase in temperature.

Therefore, the high temperature heat energy generated by the battery cell 10 is radiated while being diffused by the flowing coolant, as shown by the dotted arrows.

The heat dissipation unit 300 is divided inwardly and independently of each other, and a lower portion of the battery cell 10 exchanges heat with cooling water moving along the first heat dissipation plate 300a, and an upper portion of the battery cell 10 is formed. 1 Heat dissipates while exchanging heat with the coolant moving along the heat sink 300b.

Since the heat dissipation part 300 is made of aluminum, extra heat energy that is not conducted to the coolant is radiated to the left and right outer sides of the heat dissipation part 300, as shown by the solid arrows.

The operation of the heat dissipation unit 300 is the same in all the first and second heat dissipation plates 300a and 300b installed in the tray 200 to prevent overheating of the battery cell 10.

The tray 200 may be partially radiated by convection as air flows through the unmounted area 201b together with radiating heat through the radiating part 300.

The cooling water is moved to the connection pipe 306 through the outlet pipe 304 after all the heat exchange with the battery cell 10.

Although not described in this embodiment, the base plate 100 may be installed to cover all of the lower region of the tray 200, or may have an opening region that is partially opened to allow air flow.

When the base plate 100 is provided as described above, the heat dissipation of the battery cell 10 may be more effectively performed while simultaneously performing heat dissipation through the heat dissipation unit 300 described above, while simultaneously performing convective heat dissipation by air.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit of the invention as set forth in the appended claims. The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
