As shown in FIGS. 1 and 2 , the thermal insulation container according to the present invention includes a box body 10 , an energy storage device 20 and a temperature control device 30 . The box body 10 has an accommodation space 11 for loading goods. The energy storage device 20 is used to provide energy, such as heat or cold, to the accommodating space 11 to adjust the temperature of the accommodating space 11 . The temperature control device 30 is used to control the energy supplied to the accommodating space 11 .

The thermal insulation container according to the present invention can be a container that needs to adjust the temperature in the container, such as a refrigerated container or a heating container for air transportation, and can realize constant temperature control of the temperature in the container.

Specifically, the energy storage device 20 may be fixedly mounted to the box body 10 and disposed in the accommodating space 11 . The energy storage device 20 can be installed in any position of the accommodating space 11 as required. Preferably, the energy storage device 20 is disposed close to one side of the box body 10 along the width direction. For example, the thermal insulation container shown in the figure is an thermal insulation container for air transportation, and one side of the box body 10 in the width direction is configured to match the shape of the fuselage shell of the aircraft, that is, the box body 10 is close to the fuselage shell. One side of the body protrudes outwards. The energy storage device 20 may be disposed on the outwardly protruding portion of the accommodating space 11 , so as not to affect the loading capacity of the goods as much as possible. Of course, for a thermally insulated container with a conventional box body, the installation position of the energy storage device 20 is not limited, but it should be reasonably arranged according to the size of the energy storage device 20 so as not to affect the loading capacity of the goods as much as possible.

It should be noted that for a refrigerated container, the energy storage device 20 is used to provide cooling capacity to the accommodating space 11 . For heating the container, the energy storage device 20 is used to provide heat to the accommodating space 11 .

As shown in FIGS. 3 to 4 , the energy storage device 20 includes a storage container 21 and an energy storage body 22 provided in the storage container 21 . The storage container 21 includes an air inlet (not shown) communicating with the accommodating space 11 and an air outlet 23 , and the gas can circulate through the air inlet and the air outlet 23 . In this way, the gas can circulate and circulate between the energy storage device 20 and the accommodating space 11 to form a circulation streamline for gas circulation. The energy storage medium is arranged in the energy storage body 22 to store a certain amount of cold or heat. The gas in the box 10 can exchange energy with the energy storage body 22 , and then the gas circulates between the energy storage device 20 and the accommodating space 11 , and fluidly transfers the energy of the energy accumulating body 22 to the accommodating space 11 .

Preferably, as shown in FIG. 2 , the air inlet of the storage container 21 is arranged at the bottom of the storage container 21 , that is, the opening of the air inlet faces downward. The air outlet 23 is disposed on the top of the storage container 21 , that is, the air outlet 23 opens upward and is disposed close to the top of the box body 10 . As a result, the gas can flow from top to bottom in the accommodating space 11, so that the gas can circulate and circulate in the clockwise direction. In particular, for a refrigerated container, the cold fluid formed after the gas is exchanged with the energy accumulator 22 can flow spontaneously from top to bottom, thereby making the temperature distribution of the accommodating space 11 more uniform.

The temperature control device 30 can control the flow rate of the gas so as to maintain the temperature of the accommodating space 11 within a predetermined range. As shown in FIGS. 1 and 3 , the temperature control device 30 includes a driving part 31 for driving gas flow, a temperature controller 32 provided with a temperature setting module, a temperature sensor (not shown) and a control part (not shown) ). The driving member 31 can not only drive the flow of the gas, but also control the flow of the gas. The temperature setting module is used to set a predetermined temperature in the box 10 . The temperature sensor is disposed at any suitable position in the box body 10 for sensing the current temperature of the accommodating space 11 . The control part controls the operation state of the driving part 31 (eg, on, off, high speed or low speed, etc.) according to a predetermined temperature to adjust the current temperature.

Therefore, the predetermined temperature required for loading the cargo can be set by the temperature setting module of the temperature control device 30 , and then the operation of the driving part 31 can be controlled by a control part such as a fan, so that the gas flows, and the energy is exchanged with the energy storage body 22 . The gas flows to the accommodating space 11 to change the current temperature of the accommodating space 11 , and when the current temperature reaches a predetermined temperature, the control part controls the driving part 31 to stop operating. Optionally, the temperature control device 30 may further include a power supply component (not shown) such as a battery pack for supplying electrical energy to the temperature control device 30 . The control components may be electrical connection components such as relays.

The present invention adopts the temperature control device 30 to adjustably control the energy output by the energy storage device 20, so that when the energy storage device 20 is provided with an energy storage body 22 of a specific temperature, the energy released to the accommodating space 11 can be controlled to make The accommodating space 11 reaches different temperatures. For example, if the temperature of the energy storage body 22 is approximately minus 10°C, the temperature of the accommodating space 11 can be adjusted to other temperature ranges higher than minus 10°C, such as minus 4°C to 0°C, or minus 8°C to minus 4°C.

The temperature controller 32 can be disposed outside the box body 10, and includes a display screen, which is convenient for the operator to perform operations such as setting a value of a predetermined temperature. The temperature controller 32 is electrically connected to the temperature sensor, and receives an electrical signal from the temperature sensor, so as to display the current temperature of the accommodating space 11 on the display screen.

Further, a driving member 31 such as a fan may be provided at the air inlet and/or the air outlet 23 to control the flow of gas. The figure shows that the driving member 31 is disposed at the air outlet 23 , and the temperature control of the accommodating space 11 is realized by controlling the gas flow rate of the air outlet 23 . One or more air outlets 23 may be provided, and the number of driving parts 31 may be the same as the number of air outlets 23 , that is, each air outlet 23 may be provided with driving parts 31 , thereby making the control method of gas flow more flexible. Preferably, the driving component 31 is a fan, and the air flow can be controlled by adjusting the rotational speed of the fan.

When the air outlet 23 is provided on the top of the storage container 21, preferably, the air outlet 23 is close to the top of the box body 10, and the box body 10 is provided with a guide air duct 41 connecting the air outlet 23 and the accommodating space 11, so that the gas can pass through The guide air ducts 41 are distributed in a distributed manner, so that the energy of the energy accumulator 22 is better released to all parts of the accommodating space 11 via the flow of gas. The "guide air channel 41" can be understood as a channel for restricting the flow of gas. The guide air duct 41 may be arranged by partitions or other pipes.

Preferably, the heat preservation container further includes a plate-shaped member 42 configured to have an opening, and the plate-shaped member 42 is spaced apart from the top of the box body 10 to form the guide air duct 41 . In the illustrated embodiment, the plate-shaped member 42 is disposed between the air outlet 23 and the accommodating space 11 in the horizontal direction to form a guide air duct 41 with the top of the box body 10 . Further, the plate-shaped member 42 is horizontally arranged on the top of the box body 10 , and forms a horizontal guide air duct 41 with the thermal insulation layer at the top wall of the thermal insulation container. The opening flows to the accommodating space 11 below the plate-shaped member 42 . A plurality of openings are evenly distributed to form a plurality of gas flow lines, so that the energy is more uniformly transmitted to all parts of the accommodating space 11 .

As shown in FIG. 3 , preferably, the storage container 21 is configured as a box-type member having a storage space. The figure shows that the storage container 21 is a rectangular parallelepiped member, which can be arranged along the length direction of the box body 10 . The storage container 21 can set the size of the storage capacity according to the maximum stored energy of the expected demand of the energy storage device 20 . The storage container 21 may be provided with a box door or a lid that can be opened and closed to place and take out the energy storage body 22 . The storage container 21 separates the energy storage body 22 from the accommodating space 11 , and in order to ensure the accuracy of the temperature adjustment of the accommodating space 11 , it is not expected that the energy of the energy storage body 22 is released to the accommodating space 11 through the storage container 21 . Therefore, the storage container 21 may be provided with a heat preservation structure to reduce the loss of heat or cold energy of the energy storage body 22 . Alternatively, the storage container 21 is made of thermally insulating material.

As shown in FIGS. 4 and 5 , the energy accumulator 22 is configured as a block-like member, and can be arranged in the storage space of the storage container 21 in an array. A plurality of energy accumulators 22 are arranged at intervals to form channels for gas circulation. The energy storage body 22 is filled with an energy storage medium, and the opposite upper and lower ends of the energy storage body 22 are provided with through holes 24 to form passages for gas circulation. The gas can enter from the through hole 24 at the lower end of the energy storage body 22 , and after performing energy exchange with the energy storage medium, the gas is output from the through hole 24 at the upper end of the energy storage body 22 . In this way, the gas can directly exchange energy with the energy storage medium, which improves the efficiency of energy exchange. Preferably, a plurality of through holes 24 are provided on the lower end surface and the upper end surface of the energy storage body 22 in a uniform distribution, so that the gas enters the energy storage body 22 in a dispersed manner and contacts the energy storage medium.
