[0046] The following descriptions of the embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention can be implemented.
[0047] Example 1
[0048] This embodiment discloses a protective storage device, which includes an inner water box device. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the inner liner water box device includes an inner liner water box 1, which is made of high temperature resistant plastic material. The inner liner water box 1 includes a water box body 11, a memory chip box 12 and a water box cover 13. The memory chip box 12 is connected to the water box body 11 and is located in the water box body 11. An opening 111 is provided at the connection between the memory chip box 12 and the water box body 11, so that the memory chip 10 can be placed into the memory chip box 12 through the opening 111. The water box cover 13 is connected to the water box body 11, and the water box cover 13 is connected to the water box body 11 to form a closed whole.
[0049] In this embodiment, the memory chip cartridge 12 and the water box cover 13 are connected to the two ends of the water box body 11 respectively. The water box cover 13 is connected to the water box body 11 to form a closed whole. The closed space formed between the water box body 11 and the water box cover 13 contains water. The memory chip 10 is placed in the memory chip cartridge 12 through the opening 111, so that the water can be used to keep the temperature around the memory chip 10 at a safe temperature to prevent the memory chip 10 from being damaged by heat. The inner tank water box 1 is made of high temperature resistant plastic material. The high temperature resistant plastic material has a lower thermal conductivity than metal materials, thereby effectively reducing the thermal conductivity of the inner tank water box device. At the same time, the inner tank water box 1 includes the water box body 11, the memory chip cartridge 12 and the water box cover 13. The water box body 11, the memory chip cartridge 12 and the water box cover 13 can be manufactured by integrated injection molding and other processes, which can further reduce the processing procedures and reduce costs.
[0050] The material of the liner water box 1 is PEEK, PPS, LCP or PTFE material, that is to say, the material of the water box body 11, the memory chip box 12 and the water box cover 13 is PEEK, PPS, LCP or PTFE material. For example, the cost of the rubber liner water box 1 is only 10-15% of that of stainless steel products, and the thermal conductivity is 3% of stainless steel. The decrease in thermal conductivity can improve the utilization rate of water in the liner water box 1 and extend the time for water volatilization (evaporation), thereby improving the high temperature resistance of the protective memory. Preferably, the material of the liner water box 1 is a plastic material, and other materials such as glass fiber and carbon fiber can be added to the material to enhance the structural strength. More preferably, the material of the liner water box 1 is a composite material formed by PEEK, PPS, LCP or PTFE material mixed with 20% to 70% fiber material.
[0051] In one embodiment, the memory chip cartridge 12 and the water box body 11 can be manufactured using a one-time injection molding process. The one-time injection molding process can further simplify the processing steps, effectively reduce costs, and provide an overall structurally strong and stable structure.
[0052] In another embodiment, the memory chip box 12 and the water box body 11 can also be injection molded separately, and the memory chip box 12 is welded to the water box body 11. The memory chip box 12 is sealed by ultrasonic or laser welding. This process has good sealing effect, simple process and strong product consistency.
[0053] The memory chip box 12 and the water box body 11 are respectively injection molded, and the memory chip box 12 can also be bonded to the water box body 11. The water box body 11 and the memory chip box 12 can be bonded to each other using a waterproof sealant, which is convenient for installation and connection, and has good sealing performance.
[0054] The inner tank water box 1 also includes a sealing block 14, which is located at the opening 111 and connected to the water box body 11, so that the sealing block 14 covers the connection between the water box body 11 and the memory chip box 12 and seals the memory chip box 12 to form a closed box body. The water box body 11 and the memory chip box 12 are connected and sealed by a waterproof sealant. The sealing block 14 is connected to the water box body 11 and covers the connection between the water box body 11 and the memory chip box 12, so that the role of the waterproof sealant is guaranteed. At the same time, when the water is under high pressure, the external pressure is borne by the sealing block 14 instead of directly acting on the waterproof sealant. The waterproof sealant will not be damaged due to high pressure, resulting in a decrease in the waterproof performance of the memory chip box 12, which greatly improves the stability of the inner tank water box device.
[0055] The middle position of the sealing block 14 is provided with a slit 141 for the cable 101 of the memory chip 10 to pass through. The memory chip 10 is stored in the memory chip box 12. By providing the slit 141 in the middle position of the sealing block 14, the cable 101 of the memory chip 10 will be led out of the water box body 11 through the slit 141, so that the cable 101 is always in the center.
[0056] The internal shape of the memory chip box 12 can be stepped, so that the outer end size of the memory chip box 12 facing the opening 111 is larger than the inner size of the memory chip box 12 away from the opening 111. The internal shape of the memory chip box 12 can also be trumpet-shaped, so that the outer end size of the memory chip box 12 facing the opening 111 is larger than the inner size of the memory chip box 12 away from the opening 111. That is to say, the size of the connection between the memory chip box 12 and the water box body 11 is the largest, and the inner size is reduced accordingly, so that when the memory chip 10 is placed in the memory chip box 12, the memory chip 10 will naturally fall to the middle position, which can facilitate the positioning of the memory chip 10 and the flat cable 101 and the injection of glue, and the uniform glue sealing and waterproof performance after glue sealing can also be guaranteed after the finished product.
[0057] The inner tank water box device also includes a sealing device 2. The inner tank water box 1 is also provided with 1 to 2 pressure relief valve cavities 112 or pressure relief holes on its surface. The pressure relief valve cavity 112 or the pressure relief hole is provided with a sealing device 2 that can relieve pressure at a certain temperature and pressure by welding or bonding. The sealing device 2 is connected to the pressure relief valve cavity 112 or the pressure relief hole of the inner tank water box 1. The sealing device 2 has a pressure relief function. Through the sealing device 2, the hot steam in the inner tank water box 1 will be discharged outward through the sealing device 2, thereby achieving the effect of pressure relief and temperature reduction, and ensuring the safety of the memory chip 10 in the inner tank water box device.
[0058] Preferably, the sealing and pressure relief device is partially or entirely made of a low melting point alloy (fusible metal) material.
[0059] The inner water box 1 has a thickened portion 113 at the corners, that is, the thickness of the thickened portion 113 at the corners is greater than the thickness of other areas of the inner water box 1. The thickened portion 113 increases the thickness of each corner of the inner water box 1, thereby ensuring that the shape of the inner water box 1 is not easily changed and also increasing its strength.
[0060] Among them, the pressure relief valve cavity 112 or the pressure relief hole is set in the thickened part 113, one vertex of the inner tank water box 1 is thickened, and the pressure relief valve cavity 112 or the pressure relief hole is processed at the thickened position. The sealing device 2 will be installed and connected in the pressure relief valve cavity 112 or the pressure relief hole, so that the hot steam in the inner tank water box 1 will be discharged outward through the sealing device 2, thereby achieving the effect of pressure relief and temperature reduction, and ensuring the safety of the memory chip 10 in the inner tank water box device. At the same time, the sealing device 2 is installed and set on the thickened part 113 to achieve higher installation and connection stability.
[0061] In this embodiment, the water box cover 13 and the water box body 11 are injection molded separately, and the water box cover 13 can be bonded to the water box body 11 so that the water box cover 13 and the water box body 11 are combined into a whole. The water box body 11 and the water box cover 13 are bonded to each other with a waterproof sealant, which is convenient for installation and connection, and has good sealing performance.
[0062] The water box cover 13 can also be welded to the water box body 11 so that the water box cover 13 and the water box body 11 are combined into a whole. The water box cover 13 is sealed by ultrasonic or laser welding. This process can make the sealing performance of the product more reliable, and can also save the screw holes and sealing screw space reserved inside the water box body 11, increase the internal volume of the inner tank water box 1, reduce the processing steps and save costs.
[0063] Example 2
[0064] like Figure 5 and Figure 6 As shown, the same parts as those in Example 1 in this embodiment 2 will not be repeated, and only the different parts will be described. In this embodiment 2, the water box cover 13 is combined with the water box body 11 as a whole by mechanical fastening. Specifically, the water box cover 13 is threadedly connected to the water box body 11 by a fastener. The water box body 11 has a connection port and a plurality of first threaded holes, and the plurality of first threaded holes are respectively located on the outer edges of the connection port. The water box cover 13 has a plurality of first connection holes 131, and the plurality of first connection holes 131 correspond to the plurality of first threaded holes one by one, so that the fastener passes through the first connection hole 131 and is connected to the first threaded hole, so that the water box cover 13 is sealed to the connection port. The fastener will pass through the first connection hole 131 and connect to the first threaded hole, so that the water box cover 13 is sealed and installed and connected to the water box body 11 and completely covers the connection port, so that the inner tank water box 1 is used to hold water, and the inner tank water box 1 is very convenient to process and manufacture, and the assembly is simple, reducing the cost.
[0065] Among them, the number of the first threaded holes and the first connecting holes 131 are both 4, and the four first threaded holes are respectively located at the four corners of the water box body 11. After the four sides of the water box cover 13 are coated with glue, the first threaded holes are fastened by fasteners to form a closed inner tank water box 1.
[0066] One end of the memory chip box 12 away from the opening 111 is connected to the water box cover 13. The memory chip 10 is stored in the memory chip box 12, and one end of the memory chip box 12 near the opening 111 is connected to the water box body 11, and one end of the memory chip box 12 away from the opening 111 is connected to the water box cover 13, so that the two ends of the memory chip box 12 are respectively connected to the water box body 11 and the water box cover 13 and are located in the middle position of the inner tank water box 1, so that the internal memory chip 10 can be naturally centered. The centering of the memory chip 10 can keep the heat uniform and more stable. At the same time, the overall structural strength of the inner tank water box device is further strengthened, and the sealing effect and reliability of the water box body 11 are improved.
[0067] Specifically, one end of the memory chip box 12 is connected to the water box body 11, and the other end of the memory chip box 12 has a second threaded hole 121. Multiple first connection holes 131 are located around the outer edge of the water box cover 13. The middle area of the water box cover 13 has a second connection hole 132. The fastener passes through the second connection hole 132 and is connected to the second threaded hole 121, thereby connecting the water box cover 13 to the memory chip box 12.
[0068] The water box cover 13 has a reinforcing rib 133 on one side facing the connection port. The reinforcing rib 133 has a reinforcing effect, thereby effectively strengthening the overall structural strength of the water box cover 13, making the water box cover 13 less likely to deform and more stable. Among them, the reinforcing rib 133 is arranged on the inner side of the water box cover 13, and the reinforcing rib 133 connects the screw fastening position with the part of the water box cover 13 away from the screw hole, so that these parts are not easily deformed. When the protective storage device is subjected to high temperature so that pressure is generated inside the inner tank water box 1, the water box cover 13 will not be deformed locally due to the internal pressure, thereby eliminating the cracking at the joint between the water box cover 13 and the water box body 11 that may be caused by deformation.
[0069] The side of the water box cover 13 facing the connection port and / or the inner wall surface of the connection port has an outwardly protruding edge strip 134. An outwardly protruding edge strip 134 is designed at the inner side of the edge of the water box cover 13 that matches the water box body 11, and an outwardly protruding edge strip 134 can also be designed at the inner side of the water box body 11 that matches the water box cover 13. On the one hand, it is convenient to position the water box cover 13 during installation, and on the other hand, the contact surface of the glue coating at the sealing portion is increased, further improving the sealing reliability and firmness of the inner tank water box device.
[0070] Example 3
[0071] like Figure 7As shown, the same parts of this embodiment 3 as those of the embodiment 1 are not repeated, and only the different parts are described. In this embodiment 1, the memory chip cartridge 12 is connected to the water box body 11. In this embodiment 3, the memory chip cartridge 12 is connected to the water box cover 13, and an opening 111 is provided at the connection between the memory chip cartridge 12 and the water box cover 13, so that the memory chip 10 can be placed into the memory chip cartridge 12 through the opening 111.
[0072] The sealing block 14 is located at the opening 111 and connected to the water box cover 13, so that the sealing block 14 covers the connection between the water box cover 13 and the memory chip box 12 and seals the memory chip box 12 to form a closed box body. The sealing block 14 is connected to the water box cover 13 and covers the connection between the water box cover 13 and the memory chip box 12, so that the connection between the water box cover 13 and the memory chip box 12 is guaranteed. At the same time, when the water is under high pressure, the external pressure is borne by the sealing block 14, rather than directly acting on the waterproof sealant at the connection between the water box cover 13 and the memory chip box 12. The waterproof sealant will not be damaged due to high pressure, resulting in a decrease in the waterproof performance of the memory chip box 12, which greatly improves the stability of the inner tank water box device.
[0073] In one embodiment, the memory chip cartridge 12 and the water box cover 13 can be manufactured by a one-time injection molding process. The one-time injection molding process can further improve the processing steps, effectively reduce costs, and has high overall structural strength and stability.
[0074] In another embodiment, the memory chip box 12 and the water box cover 13 are injection molded separately, and the memory chip box 12 can be bonded to the water box cover 13. The water box cover 13 and the memory chip box 12 can be bonded to each other with a waterproof sealant, which is convenient for installation and connection, and has good sealing performance.
[0075] The memory chip box 12 can also be welded to the water box cover 13. The memory chip box 12 is sealed by ultrasonic or laser welding, and this process has good sealing effect, simple process and strong consistency of product.
[0076] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
