Meanwhile, a heat exchange component is further arranged in the needle bed box body 1, the heat exchange component comprises a heat exchange pipeline, a heat exchanger 21 and a wind force piece 22, the heat exchanger 21 is connected with an external heat exchange system through the heat exchange pipeline, the heat exchanger 21 is arranged in the heat exchange cavity 12, the wind force piece 22 is arranged at the heat exchange port 13, for example, the wind force piece 22 is arranged in the needle bed cavity 11 and/or the heat exchange cavity 12 (when the wind force piece 22 is in a plurality of cavities, the wind force piece 22 can be distributed in two cavities) and is arranged close to the heat exchange port 13, and the wind port is opposite to the heat exchange port 13, so that air flows circularly flow between the heat exchange cavity 12 and the needle bed cavity 11. In this way, the air flow in the needle bed cavity 11 flows into the heat exchange cavity 12 to exchange heat, and the air flow after heat exchange flows back into the needle bed cavity 11, and continuously and circularly flows to heat or cool the needle bed cavity 11, so that the temperature of the needle bed cavity 11 is maintained at a required temperature.

Therefore, the needle bed cabinet 10 provided by the application has the closed needle bed 6 box on the cabinet body, and the heat exchange component is arranged in the needle bed cabinet to regulate and control the temperature of the needle bed cavity 11, so that the needle bed cavity 11 can be at a required temperature. Therefore, an independent temperature environment is formed by one needle bed 6 box or one needle bed cabinet 10, the temperature of one needle bed cabinet 10 is independently regulated by the heat exchange component, the space is small, the temperature is easy to realize, the temperature regulation and control reaction is fast, the temperature regulation and control efficiency is high, the temperature control effect is good, the temperature environment required by formation or capacity division operation is met, the temperature control of the whole environment is not required to be carried out on a workshop where the whole formation component device is located, the structure of a temperature control system required to be arranged is simplified, the operation cost can be saved to a great extent, and the working environment around equipment is optimized.

The needle bed cabinet of claim 1, wherein the wind power component is connected with the heat exchanger to form a heat exchange module, and a wind port on one side of the wind power component is opposite to the heat exchange port, and a wind port on the other side of the wind power component is opposite to the heat exchanger.

4. A needle bed cabinet according to claim 3, wherein each heat exchange module comprises a connection seat and is provided with at least two heat exchangers, each heat exchanger being provided with a plurality of wind members; the heat exchanger and the wind power piece are both fixed on the connecting seat and are connected to the heat exchange port through the connecting seat.

5. The needle bed cabinet of claim 1, wherein the heat exchange assembly further comprises a plurality of fans disposed in the needle bed cavity, the plurality of fans being dispersed around the needle bed or the plurality of fans being arranged in an array to form a fan layer, the fan layer being laid on top of or under or on a side of a bed frame of the needle bed.

6. The needle bed cabinet of claim 1, wherein at least two needle bed cavities are provided, and the heat exchange cavities are provided on both sides of each needle bed cavity.

7. The needle bed cabinet of claim 1, further comprising a circuit assembly comprising:

8. The needle bed cabinet of claim 7, wherein the first cooling assembly comprises an air cooling assembly and/or a liquid cooling assembly; the second cooling assembly includes an air cooling assembly and/or a liquid cooling assembly.

9. The needle bed cabinet of claim 7, wherein the bypass module and/or the DC/DC module is provided with a housing, and the housing is a sealed structure.

10. A forming or volumetric machine comprising a plurality of needle bed cabinets according to any one of claims 1 to 9, a plurality of said needle bed cabinets being combined into a unitary cabinet.
