Abstract

A transport refrigeration unit includes at least one component, a frame (136), and an energy storage module (110). The at least one component is driven by electrical power. The frame (136) is constructed and arranged to structurally support the plurality of components. The energy storage module (110) is adapted to provide the electrical power, and is internally located and supported by the frame (136).

First claim

What is claimed is:

1. A transport refrigeration unit for a trailer of a tractor trailer system, the transport refrigeration unit comprising:
at least one refrigeration component driven by electric power;
a frame constructed and arranged to structurally support the at least one refrigeration component;
an energy storage module adapted to provide the electrical power, and internally located and supported by the frame,
wherein the frame is tubular,
wherein the frame includes a first tubular member directly supporting a first refrigeration component of the at least one refrigeration component and a second tubular member directly supporting a second refrigeration component of the at least one refrigeration component, and
wherein the energy storage module includes a first battery located in the first tubular member and configured to drive the first refrigeration component and a second battery located in the second tubular member and configured to drive the second refrigeration component.

2. The transport refrigeration unit set forth in claim 1 , further comprising:
an electrical bus electrically connected between the at least one refrigeration component and the energy storage module, wherein the electrical bus is substantially located inside the frame.

3. The transport refrigeration unit set forth in claim 2 , wherein the electrical bus includes a plurality of power conductors.

4. The transport refrigeration unit set forth in claim 3 , wherein the electrical bus includes a plurality of control conductors.

5. The transport refrigeration unit set forth in claim 1 , wherein the energy storage module is at least one battery.

6. The transport refrigeration unit set forth in claim 1 , wherein the frame includes a tube extending along a centerline, the tube including an outer surface facing radially outward and an inner surface facing radially inward, and wherein the inner surface defines a cavity and the energy storage module is disposed in the cavity.

7. The transport refrigeration unit set forth in claim 1 , wherein the at least one refrigeration component includes a compressor.

8. The transport refrigeration unit set forth in claim 1 , wherein the at least one component includes at least one fan motor.

9. The transport refrigeration unit set forth in claim 1 , wherein the first refrigeration component is a compressor and the second refrigeration component is a fan motor.

10. The transport refrigeration unit set forth in claim 1 further comprising:
an electrical bus electrically connected between the first and second batteries, and disposed in the frame.

11. The transport refrigeration unit set forth in claim 10 , wherein the frame includes a third tubular member, the first, second and third tubular members each defining respective first, second and third cavities, and the third cavity extends between and is in communication with the first and second cavities, and wherein the first battery is located in the first cavity, the second battery is located in the second cavity, and the electrical bus is at least in-part located in the third cavity.
