[0002] With the development of the national economy, electricity supply is becoming increasingly tight, and the difference between peak and valley power consumption is becoming increasingly pronounced. To stabilize the power grid, the government has introduced a peak-valley electricity pricing policy, encouraging users to consume electricity during off-peak hours. Air conditioners and other refrigeration equipment are major electricity consumers in daily life and work. Addressing the issue of off-peak electricity consumption for refrigeration equipment is crucial to the successful implementation of the national peak-valley electricity pricing policy.

[0003] In this regard, how to save electricity has become a common phenomenon in the lives of many families. In the summer, after using refrigeration compressor equipment to cool water to 8 degrees, the water below 8 degrees is filled into the air-conditioning circulation water tank for use. Then the water is heated to about 13 degrees and then flows back to the refrigeration equipment to be cooled again to below 8 degrees before being reused. However, each time the refrigeration equipment cools the water, it consumes electricity, which will also cause a lot of power loss and a higher electricity bill. Utility Model Content

[0031] The present invention is described in detail below with reference to the accompanying drawings.

[0032] like Figure 1-4 As shown, a phase change material cold storage structure includes a cold storage seat 1 and a heat sink seat 3 connected to the cold storage seat 1. The cold storage seat 1 is installed on the top of the heat sink 3. A cold storage chamber 11 is formed in the cold storage seat 1. The cold storage chamber 11 is arranged with multiple cold storage members 14 formed from phase change material and cold storage grooves 13 for mounting the cold storage members 14. An air inlet 15 for the blown air of the air conditioner is formed at one end of the cold storage chamber 11, and an air outlet 19 is formed at the other end. A guide channel 12 is formed between the air inlet 15 and the air outlet 19. The cold storage grooves 13 are vertically connected to the guide channel 12. The multiple cold storage grooves 13 are arranged at intervals along the length direction of the guide channel 12.

[0033] A cold storage device and a radiator are provided. The cold storage device is evenly distributed with guide channels 12. Cold storage parts 14 are evenly distributed between the guide channels 12. The cold storage parts 14 made of phase change material are used to absorb heat, cool and store the cold air entering the cold storage chamber 11, and turn it into solid ice. When a certain amount of heat is stored, the heat can be released to the solid through the cold storage part 14, and the solid is turned into liquid to dissipate heat. The heat is discharged through the heat sink 3 and cold air can be blown out. According to the off-peak electricity consumption, the cold storage part 14 made of phase change material is used to release heat for cooling, which increases the energy-saving effect, reduces the use rate of air conditioners, and greatly reduces electricity consumption.

[0034] Furthermore, the air inlet 15 is provided with an exhaust module, which includes an exhaust fan 18 and a pair of spaced-apart guide bars 16 for mounting the exhaust fan 18. A support frame 17 is provided between the two guide bars 16. The support frame 17 is movable along the length of the guide bars 16, and the exhaust fan 18 is mounted on the support frame 17. The exhaust fan 18 can be mounted via the support frame 17. After the exhaust fan 18 is mounted to the air inlet 15, the air intake of the cold storage seat 1 is increased, and a portion of the cold air blown out by the indoor air conditioner enters the cold storage seat 1 for storage, further improving the cold storage efficiency. The exhaust fan 18 can also be removed by sliding the support frame 17, improving the portability of the assembly and disassembly.

[0035] The cold storage component 14 is configured as a cold storage tube that is adapted to the shape of the cold storage tank 13. The cold storage tube is filled with phase change liquid. When the cold air passes through the guide channel 12 and the cold storage tank 13, the phase change liquid in the cold storage tube absorbs a large amount of cold air energy, freezes from liquid to solid, and stores energy.

[0036] Preferably, the phase change liquid is water.

[0037] A cooling plate 2 is installed between the heat dissipation seat 3 and the cold storage seat 1; the heat dissipation seat 3 is connected to the cold storage seat 1, and the cooling plate 2 is provided with a through groove 21 for the heat dissipation gas in the cold storage chamber 11 to be discharged into the heat dissipation seat 3, and a cooling module for cooling the passing heat dissipation gas is installed through the groove 21.

[0038] In this embodiment, when it is necessary to dissipate heat after the phase change liquid in the cold storage tube is frozen, the solid in the cold storage tube is heated and gradually turns into liquid. At this time, the heat released by the cold storage tube is cold air, which passes through the groove 21 of the cooling plate 2 and enters the heat sink 3 for discharge, so that the indoor temperature can be reduced, the energy-saving effect is increased, the air conditioning usage rate is reduced, and the electricity consumption is greatly reduced.

[0039] Preferably, the cooling module includes a left cooling rod 22 and a right cooling rod 23 installed in the through slot 21, the left cooling rod 22 and the right cooling rod 23 are respectively installed with a drive seat 24, the drive seat 24 is installed with a cooling plate 25, and the drive seat 24 can move along the length direction of the corresponding left cooling rod 22 and right cooling rod 23 respectively; the temperature of the cold air passing through the cooling plate 2 can be further reduced, so that the indoor temperature can be effectively reduced.

[0040] Furthermore, the left cooling rod 22 and the right cooling rod 23 are respectively formed with external thread structures with opposite thread directions, and the drive seat 24 is installed with a screw sleeve seat 26, which cooperates with the external thread structure to adjust the axial position of the drive seat 24; the left cooling rod 22 and the right cooling rod 23 are rotated respectively, and the screw sleeve seat 26 installed on the drive seat 24 cooperates with the external thread structure. Accordingly, the drive seat 24 will move axially, and the drive seats 24 installed on the left cooling rod 22 and the right cooling rod 23 will separate from or approach each other, and the blocking area of ​​the passing groove 21 will change, and the temperature of the cold air passing through the cooling plate 2 can be adjusted. When the drive seats 24 of the left cooling rod 22 and the right cooling rod 23 will separate from each other, the contact area between the cold air and the cooling plate 25 will decrease, and the cooling amplitude will decrease; conversely, when the drive seats 24 of the left cooling rod 22 and the right cooling rod 23 will approach, the contact area between the cold air and the cooling plate 25 will increase, and the cooling amplitude will increase.

[0041] Furthermore, the cooling plate 25 is formed with a limiting strip 28, and a limiting groove 27 is formed along the length direction through the side wall of the groove 21, and the limiting strip 28 can be inserted into the limiting groove 27; when the left cooling rod 22 and the right cooling rod 23 rotate, the driving seat 24 will not rotate, and the limiting groove 27 formed on the side wall of the groove 21 will block the longitudinal swing of the limiting strip 28. When the driving seat 24 moves along the length direction of the left cooling rod 22 and the right cooling rod 23, the limiting strip 28 can move along the length direction of the limiting groove 27, thereby preventing the driving seat 24 from rotating.

[0042] Furthermore, a pair of fitting bearing seats 29 are installed in the middle of the groove 21, one bearing seat 29 is for inserting one end of the left cooling rod 22, and the other bearing seat 29 is for inserting one end of the right cooling rod 23. The left cooling rod 22 and the right cooling rod 23 can be rotatably supported by the bearing seats 29 respectively to prevent the left cooling rod 22 and the right cooling rod 23 from longitudinal displacement.

[0043] Preferably, the outer ends of the left cooling rod 22 and the right cooling rod 23 extend outward respectively, and rotating handles are installed on the outer ends of the left cooling rod 22 and the right cooling rod 23 respectively.

[0044] An exhaust cavity 31 is formed in the heat sink 3 and is connected to the groove 21 of the cooling plate 2. A cooling fan 35 is installed in the exhaust cavity 31. An exhaust port 32 is formed at the bottom of the heat sink 3. An exhaust plate 33 is installed at the exhaust port 32. The exhaust plate 33 is formed with multiple guide ports 34 of different sizes for air discharge. The cooling fan 35 in the exhaust cavity 31 can discharge the cold air in the exhaust cavity 31 through the guide port 34 to the outside to achieve cooling.

[0045] In summary, it can be seen that the present invention has the above-mentioned excellent characteristics, which can enhance its performance unprecedented in the past and become a product with great practical value.

[0046] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scope. The content of this specification should not be understood as limiting the present invention.
