Heat exchange and heat preservation board

Abstract

A heat exchange and insulation board includes an insulation material body and a heat exchange unit. The insulation material body includes at least an insulation material layer, an outer heat exchange airflow cavity, and an outer additional material layer arranged sequentially from one side to the other. The heat exchange unit includes a compressor connected to a refrigerant pipeline. An expansion valve is also installed on the refrigerant pipeline, and the refrigerant pipeline at the outer end of the expansion valve is located inside the outer heat exchanger. The outer heat exchanger is connected to the outer heat exchange airflow cavity through a heat exchange pipeline, and a fan is installed on the pipeline. The outer heat exchange cavity can absorb the cold / heat transferred from the inside to the outside. The absorbed cold / heat flows back to the inner heat exchanger through the refrigerant under the action of the heat exchange unit, and driving the cold / heat return requires only a small amount of electricity. This insulation material body significantly reduces the heat transfer between the inside and the outside, greatly improving the insulation effect.

Description

Technical Field

[0001] This utility model relates to the field of thermal insulation boards, and in particular to a heat exchange thermal insulation board. Background Technology

[0002] The difference in effectiveness of traditional insulation methods lies in the selection of insulation materials and the control of insulation layer thickness. Generally speaking, insulation materials with better insulation performance and greater thickness provide better insulation results. This is achieved by reducing the heat transfer coefficient, thus achieving the purpose of insulation. However, this approach has drawbacks such as bulky equipment and increased manufacturing costs.

[0003] In particular, existing insulation materials lack temperature regulation or heat exchange configurations, making it impossible to actively adapt to the insulation requirements of the insulation chamber, thereby further reducing the heat exchange rate and improving the insulation effect.

[0004] There is currently no corresponding solution to the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a heat exchange and insulation board with a multi-layer board combination, in which temperature control is implemented in the cavity between the boards to reduce the heat exchange rate, thereby improving the heat preservation effect based on the heat preservation target.

[0006] The equipment includes a main body of insulation material and a heat exchange unit;

[0007] The main body of the thermal insulation material includes at least a thermal insulation material layer, an outer heat exchange airflow cavity, and an outer additional material layer arranged sequentially from one side to the other.

[0008] The heat exchange unit includes a compressor, which is connected to a refrigerant pipeline. An expansion valve is also installed on the refrigerant pipeline, and the refrigerant pipeline at the outer end of the expansion valve is installed inside the outer heat exchanger.

[0009] The outer heat exchanger is connected to the outer heat exchange airflow cavity through a heat exchange pipe, and a fan is installed on the pipe.

[0010] Preferably, the refrigerant pipeline is filled with refrigerant.

[0011] The effect achieved is that the compressor drives the refrigerant to circulate in the refrigerant pipes, and based on the setting of the expansion valve, the refrigerant pipes at both ends are one cold and one hot. Also, since the outer heat exchange pipe is set in the outer heat exchanger, and the outer heat exchanger is connected to the outer heat exchange airflow chamber and exchanges heat through the fan, the outer fan drives the airflow to flow through the outer heat exchange airflow chamber and then through the outer heat exchanger. When the airflow flows through the outer airflow chamber, it absorbs the cold / heat transferred from the inside of the insulation layer to the outside. When it flows through the outer heat exchanger, it transfers this part of the cold / heat to the refrigerant. This part of the cold / heat is pumped to the inner heat exchanger through the heat exchange unit. In this way, the cold / heat that has passed through the insulation layer is recovered to the inside with less electricity, thereby saving electricity.

[0012] The beneficial effects of this invention are as follows: This invention fills a gap in the market by achieving auxiliary temperature maintenance of the inner and outer surfaces of the insulation material based on the target temperature through the active operation of the heat exchange unit. In particular, with this configuration, the temperature difference between the inner side of the plate and the ambient temperature of the chamber is smaller, and the heat exchange rate is lower, thereby improving the insulation effect.

[0019] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0020] ReferenceFigure 1 , Figure 2 The present invention provides a heat exchange and insulation board, comprising an insulation material body and a heat exchange unit.

[0021] The main body of the thermal insulation material includes at least a thermal insulation material layer 1, an outer heat exchange airflow cavity 2, and an outer additional material layer 16 arranged sequentially from one side to the other.

[0022] The heat exchange unit includes a compressor 6, which is connected to a refrigerant pipe 8. An expansion valve 7 is also provided on the refrigerant pipe 8, and the refrigerant pipe 8 at the outer end of the expansion valve 7 is located inside the outer heat exchanger 5.

[0023] The outer heat exchanger 5 is connected to the outer heat exchange airflow cavity 2 through a heat exchange pipe, and a fan is installed on the pipe.

[0024] Preferably, the refrigerant pipe 8 is filled with refrigerant.

[0025] Example 1. The main body of the thermal insulation material includes, from the inside out, an inner additional material layer 18, an inner heat exchange airflow channel 17, a thermal insulation material layer, an outer heat exchange airflow channel 2, and an outer additional material layer 16;

[0026] The refrigerant pipes 8 at both ends of the expansion valve 7 are respectively installed in the outer heat exchanger 5 and the inner heat exchanger 9;

[0027] The outer heat exchanger 5 and the inner heat exchanger 9 are respectively connected to the inner heat exchange airflow channel 17 and the outer heat exchange airflow channel 2 through heat exchange pipes, and fans are respectively installed on the two heat exchange pipes.

[0028] During operation, compressor 6 drives the refrigerant to circulate in refrigerant pipe 8. Due to the expansion valve 7, the refrigerant pipes 8 at both ends are switched between cooling and heating. Furthermore, since two heat exchange pipes are respectively located within the outer heat exchanger 5 and the inner heat exchanger 9, and the outer and inner heat exchangers 5 and 9 are respectively connected to the inner heat exchange airflow chamber 17 and the outer heat exchange airflow chamber 2, and heat exchange occurs through a fan, the inner heat exchange chamber can be used for either cooling or heating to ensure that the temperature of the inner additional material layer is equal to or close to the internal temperature, thus isolating heat transfer between them. The outer heat exchange chamber... The chamber can be used for heating or cooling, so that the outer additional material layer is at the same or similar temperature as the outside, thus isolating the heat transfer between the two. Because there is a temperature difference between the inner and outer heat exchange channels, heat will be transferred between them through the insulation material. The heat transferred cold / heat will continuously flow back in the refrigerant pipe due to the action of the heat exchange unit, forming a cycle. This cycle will reach an equilibrium state, and driving this heat cycle only requires a small amount of electrical energy. Ultimately, the main body of the insulation material isolates the heat transfer between the inside and the outside, thereby improving the insulation effect.

[0029] Example 2, the heat exchange fan includes an outer heat exchange fan 3 and an inner heat exchange fan 11;

[0030] The heat exchange pipes include an inner heat exchange pipe 10 and an outer heat exchange pipe 4;

[0031] The outer heat exchange fan 3 is connected to the outer heat exchange pipe 4, and the outer heat exchange pipe 4 is connected to the outer heat exchange airflow channel 2 chamber.

[0032] The inner heat exchange fan 11 is connected to the inner heat exchange pipe 10, and the inner heat exchange pipe 10 is connected to the inner heat exchange airflow channel 17.

[0033] An outer airflow temperature sensor 15 and an inner airflow temperature sensor 14 are respectively installed on the outer heat exchange pipe 4 and the inner heat exchange pipe 10.

[0034] In Example 3, an inner ambient temperature sensor 12 and an outer ambient temperature sensor 13 are respectively installed in the spaces inside and outside the main body of the thermal insulation material.

[0035] Preferably, the outer airflow temperature sensor 15, the inner airflow temperature sensor 14, the inner ambient temperature sensor 12, and the outer ambient temperature sensor 13 are respectively connected to the integrated control system, and the integrated control system is connected to the compressor 6.

[0036] The effect achieved is that, through the signal reporting of multiple sensors, the integrated control system coordinates the control of the compressor 6 efficiency and the direction of the cooling and heating cycle.

[0037] Example 4, refer to the accompanying drawings in the specification. Figure 3 and Figure 4 The inner heat exchange airflow cavity 17 and the outer heat exchange airflow cavity 2 are respectively provided with multiple layers of partitions, and airflow gathering channels are configured at both ends of these partitions.

[0038] This achieves the effect of facilitating the combination of multiple plates at intervals, and facilitates the overall assembly of the pipeline based on the airflow convergence channel.
