Description

Technical Field

[0001] This utility model relates to the field of phase change material constant temperature technology and thermal insulation material technology in the transportation of temperature-sensitive items, and in particular to an energy storage intelligent temperature control logistics constant temperature box. Background Technology

[0002] Temperature-controlled logistics refers to a high-end logistics system that uses technology to precisely control temperature throughout the entire transportation, storage, and distribution process. This ensures that temperature-sensitive items remain within a specific temperature range, guaranteeing their quality, safety, and efficacy. It is commonly found in industries such as food, pharmaceuticals, vaccines, cell and gene therapy, biological products, and high-end chemical reagents. As of 2025, over 70% of pharmaceutical products sold globally require strict temperature control during storage and transportation. Simultaneously, with the rapidly increasing demand for temperature-sensitive drugs such as pharmaceuticals, vaccines, and active pharmaceutical ingredients (APIs), traditional transportation methods can no longer meet the market's high requirements for product quality, delivery timeliness, and safety. Therefore, long-term, stable, cost-effective temperature control methods have become crucial in solving this problem, especially given the current surge in demand.

[0003] Traditional temperature-controlled logistics insulated boxes suffer from several drawbacks, including short insulation time (<72 hours), difficulty in achieving precise temperature control (±5℃), narrow temperature control range adaptability (-20-20℃), limited usable space, high weight per unit volume, and high transportation costs. Traditional insulated boxes are typically made of polypropylene (PP) or polyurethane (PU) foam. These materials have high thermal conductivity, resulting in short insulation time and large temperature fluctuations. For extended insulation and precise temperature control, additional batteries, air conditioning equipment, or power connections are required, especially in air logistics where stable power supplies are unavailable and large-capacity batteries are difficult to carry. Secondly, the refrigerants used in traditional boxes have low energy density, making it difficult to maintain precise temperature control over extended periods. Increasing the insulation time necessitates increasing the amount of refrigerant, leading to increased weight and significantly higher transportation costs. Furthermore, traditional boxes lack monitoring devices to assess the thermal conductivity decay of the insulation material, posing uncontrollable risks to the transportation of high-value, temperature-sensitive goods.

[0004] The energy storage-type intelligent temperature-controlled logistics constant temperature box is an intelligent constant temperature device used in temperature-controlled logistics processes to ensure long-term stable (insulation time > 168 hours) and precise temperature control (less than ±0.5-1℃) for temperature-sensitive items. It has a wide temperature range (-75-175℃), a wide range of applications, and also boasts advantages such as economic efficiency, high cost, and environmental friendliness. It mainly consists of a polymer material outer casing, vacuum insulation material components, a high-enthalpy phase change material constant temperature component, and a vacuum degree sensing component. Internally, it is equipped with a wireless monitoring system for temperature, humidity, and positioning. Without any power supply or batteries, it can achieve long-term stable and precise temperature control during the transportation of temperature-sensitive items, ensuring product quality, safety, and timeliness. Utility Model Content

[0005] The purpose of this invention is to provide an energy storage intelligent temperature-controlled logistics constant temperature box to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy storage intelligent temperature-controlled logistics constant temperature box, comprising a polymer material outer casing component, a vacuum insulation material component, a high-enthalpy phase change material constant temperature component, and a vacuum degree sensing component. The vacuum insulation material component is tightly placed inside the inner wall of the polymer material outer casing component. A high-enthalpy phase change material constant temperature component with different phase change point temperatures selectable according to specific temperature-controlled transportation scenarios is also tightly placed inside the vacuum insulation material component. The vacuum degree sensing component is placed inside the vacuum insulation material component and can monitor changes in vacuum degree at any time. This energy storage intelligent temperature-controlled logistics constant temperature box, by using a vacuum insulation material component made of insulation material, a high-enthalpy phase change material constant temperature component made of phase change energy storage material, a vacuum degree sensing component made of wireless pressure sensors, and an environmentally friendly polymer material outer casing component, combined with digital visualization monitoring technology, effectively solves the problems of long-term stable and precise temperature control, limited effective space utilization, large unit volume weight, and high transportation costs during the temperature-controlled transportation of temperature-sensitive items.

[0007] Furthermore, the polymer material outer casing component includes a main casing, handles, a lid, air vents and air vent buckles I, a latch, a lock groove, a vacuum insulation material component I, a vacuum pressure sensor I, air vents and air vent buckles II, a vacuum insulation material component II, and a vacuum pressure sensor II. The main casing has symmetrical handles on its left and right sides, and a lid is connected to the top of the main casing. An air vent and air vent buckle I are provided on one edge of the lid, and a latch is provided on the top edge of the main casing near the air vent and air vent buckle I. The inner surface of the lid is connected to the vacuum insulation material component I. A vacuum pressure sensor I is installed at the center of the surface of the vacuum insulation material component I near the horizontal central axis of the main casing. An air vent and air vent buckle II are provided near the center point of the two lock grooves on the front central axis of the main casing. The vacuum insulation material component II is tightly fitted to the inner wall of the main casing, and the vacuum pressure sensor II is placed at the bottom center of the vacuum insulation material component II.

[0008] Furthermore, the main body and the lid are integrated into one structure, and both the main body and the lid are made of polymer materials. The vacuum insulation material component I on the lid is made using U-Vanis vacuum insulation technology.

[0009] Furthermore, the air vent and air vent buckle I and air vent and air vent buckle II are structurally matched, the locking tongue and locking groove are structurally matched, and the vacuum insulation material component I and the box cover are detachably connected.

[0010] Furthermore, the vacuum insulation material component includes an outer cladding material, a core material, a catalytic adsorption component, a vacuum degree sensing component I, and a vacuum degree sensing component II. The outer cladding material contains the core material, the catalytic adsorption component, the vacuum degree sensing component I, and the vacuum degree sensing component II, and the outer surface of the outer cladding material is covered with a high-barrier film.

[0011] Furthermore, the core material is made of vacuum insulation material. Vacuum insulation material component I and vacuum insulation material component II adopt the same structure. Vacuum insulation material component II is integrally formed by a special mold and is in a five-sided vacuum state. It is tightly bonded and combined with the polymer material outer box component, vacuum insulation material component I, and high enthalpy phase change material constant temperature component.

[0012] Furthermore, the high enthalpy phase change material isothermal component is made of high enthalpy BeiPCM phase change material and includes a front phase change material temperature element, a rear phase change material temperature element, a left phase change material temperature element, a right phase change material temperature element, an upper phase change material temperature element, and a lower phase change material temperature element. The temperature elements are assembled together by interlocking with each other through a degree angle structure.

[0013] Furthermore, the vacuum sensing component consists of a vacuum sensor chip and a vacuum sensor packaging material, wherein the vacuum sensor packaging material covers the outer periphery of the vacuum sensor chip.

[0014] This utility model provides an energy storage type intelligent temperature-controlled logistics constant temperature box, which has the following beneficial effects:

[0015] 1. This utility model relates to a high-enthalpy phase change material constant-temperature component installed inside a vacuum insulation material component. The entire high-enthalpy phase change material constant-temperature component consists of six temperature elements: a front phase change material temperature element, a rear phase change material temperature element, a left phase change material temperature element, a right phase change material temperature element, an upper phase change material temperature element, and a lower phase change material temperature element. These temperature elements are interlocked at 45-degree angles to form a hexagonal rectangular structure. During temperature-controlled transportation, temperature-sensitive items are placed within this rectangular structure, thus achieving long-term stable temperature-controlled transportation. The entire high-enthalpy phase change material (PCM) thermostatic component is made of BeiPCM PCM material. The BeiPCM PCM series features high energy density (enthalpy range of 220-360 kJ / kg) and a wide temperature range (-75-175℃). Under the same conditions, it can significantly reduce the weight and size of the temperature-controlled logistics thermostatic box, increase effective capacity, and save users substantial energy and transportation costs, achieving the goals of long-term stability, precise temperature control, and economic efficiency. BeiPCM PCM material refers to a substance that automatically absorbs or releases a large amount of latent heat when undergoing a phase change (such as from solid to liquid or from liquid to solid), while maintaining a nearly constant temperature. This process of changing the state of matter is called a phase transition process. Its characteristic is that the temperature remains constant during the phase transition, but the energy absorbed or released is very significant. By using BeiPCM phase change material, the entire high enthalpy phase change material isothermal component automatically absorbs or releases a large amount of energy when a phase change occurs, maintaining a constant temperature within the hexagonal rectangular structure space. It can easily achieve constant temperature for 168 hours or more, with a temperature control accuracy of less than ±0.5-1℃. At the same time, the temperature range for temperature control in logistics transportation can be arbitrarily defined between -75℃ and 175℃. It has the characteristics of high energy storage density, long-term stability, and green environmental protection, integrating energy saving, energy storage, energy use, and temperature regulation functions.

[0016] 2. This utility model relates to a vacuum insulation material component composed of an outer casing, a core material, a catalytic adsorbent, and two vacuum degree sensing components (I and II). The outer casing covers the outer periphery of the core material and the catalytic adsorption component. The outer casing has a resin substrate, a resin coating, or a high-barrier film, providing puncture resistance, heat insulation, and air tightness. The core material is made of materials with fine pores, such as glass fiber or silicon powder, and is sealed under reduced pressure to form a vacuum insulation material. The catalytic adsorption component contains a catalyst and an adsorbent. The catalyst can catalytically decompose organic gases that the adsorbent cannot adsorb into small molecules that the adsorbent can adsorb, thus ensuring a high vacuum level inside the vacuum insulation material. Its unique microporous structure suppresses heat conduction, heat convection, and heat radiation to the physical limits under atmospheric pressure, resulting in a thermal conductivity as low as 0.0012 W / (mK). Its insulation performance is more than 20 times that of traditional polyurethane foam insulation materials. Under the same conditions, the vacuum insulation material component has advantages such as higher insulation performance, thinner thickness, and lighter weight. Both vacuum insulation material component I and vacuum insulation material component II are integrally manufactured using U-Vanis vacuum insulation technology. Therefore, this method allows the entire energy storage temperature-controlled logistics constant temperature box to achieve better insulation, larger usable space, and lighter weight per unit volume compared to traditional temperature-controlled logistics insulated boxes under the same conditions. Specifically, under the same conditions, the energy storage intelligent temperature-controlled logistics constant temperature box can reduce weight by more than 20%, while increasing usable space by more than 15%. Furthermore, its structure can achieve excellent heat and cold insulation with a very thin thickness, easily maintaining the temperature defined by BeiPCM, significantly reducing transportation costs by more than 20%, and powerfully mitigating the impact of the external environment on the transportation of temperature-sensitive items.

[0017] 3. In this utility model, the vacuum degree sensing components (vacuum degree sensing component I and vacuum degree sensing component II) are covered by an outer packaging material on the outer periphery. They are used to monitor the gas pressure inside the vacuum insulation material component, thereby ensuring the quality and performance of U-Vanis after each use and providing a strong guarantee for the safety of temperature-sensitive items during transportation.

[0018] 4. This utility model features a modular design for the entire energy storage constant temperature box, making operation simple and quick. All components are made of lightweight, green, and recyclable materials, offering both economic and ecological advantages. This one-stop design not only significantly reduces packaging, labor, and transportation costs during temperature-controlled transport but also fully embodies the core concept of efficient, green, and sustainable development for energy storage constant temperature boxes. By organically combining a polymer outer casing, vacuum insulation materials, high-enthalpy phase change materials, vacuum pressure sensors, and digital visualization technology, it effectively solves problems in traditional temperature-controlled transport such as short insulation time (<72 hours), large temperature control accuracy deviation (±5℃), narrow temperature control range adaptability (-20-20℃), small effective space utilization, large unit volume weight, and high transportation costs. It requires no external energy supply, is safe and reliable, environmentally friendly and lightweight, and can cover the temperature-controlled transport of temperature-sensitive items throughout their entire life cycle. It is the best choice for transporting temperature-sensitive items such as pharmaceuticals, vaccines, plasma, organs, biological products, and food. Attached Figure Description
