Description

Technical Field

[0001] This utility model relates to the field of air dehumidification, drying and desorption regeneration technology, and in particular to a vehicle air suspension drying tank with a built-in metal heat-conducting partition. Background Technology

[0002] In vehicle air suspension systems, the compressed air output from the compressor contains impurities such as moisture and oil mist. If left untreated, this can cause corrosion, icing, or failure of components such as air lines, airbags, and control valves. To ensure system reliability, a desiccant is typically installed in the air source circuit. This desiccant (such as molecular sieves or activated alumina) filled within the can adsorbs moisture and impurities from the air. As operating time increases, the desiccant gradually becomes saturated, requiring desorption via heating to remove the adsorbed moisture and impurities, thus enabling desiccant regeneration. In existing technologies, heating film elements have been adopted by some vehicle-mounted desiccants due to their flexibility, adaptability, and uniform heating surface. This method typically involves attaching a flexible heating film to the inner wall of the desiccant shell, transferring heat to the internal desiccant through surface heating. However, heating films still have the following shortcomings in the application of vehicle-mounted desiccants:

[0003] 1. Long heat conduction path: When the membrane is attached to the inner wall of the shell, heat must be transferred through the gaps or contact surfaces between the desiccants, resulting in low heat conduction efficiency. 2. Limited heat distribution: Due to the granular structure of the desiccant, heat tends to concentrate in localized areas near the membrane during heating, while areas further away from the membrane heat up slowly, leading to uneven regeneration. 3. Slow cooling rate: After heating ends, the residual temperature of the internal desiccant remains high, resulting in a slow cooling rate, which is not conducive to quickly restoring the system to normal operation.

[0004] Therefore, the existing drying tank heating methods based on heating film elements still need improvement in terms of thermal efficiency, heating uniformity, and temperature control response speed. Utility Model Content

[0005] The purpose of this invention is to provide a vehicle air suspension drying canister with a built-in metal thermally conductive partition, which has high thermal conductivity, uniform heating, and fast heat dissipation.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A vehicle air suspension dryer canister with built-in metal thermally conductive baffles includes a canister body. A detachable metal thermally conductive liner is installed inside the canister body. A heating film element is attached to the outer wall of the metal thermally conductive liner.

[0014] Preferably, the heating film element is a flexible electric heating film, and the heating film element is connected to a power source.

[0015] More preferably, the heating film element is connected to a control system for controlling the heating of the heating film element.

[0016] Preferably, the tank body is provided with mounting brackets for connecting to the air suspension system, and each mounting bracket is provided with bolt holes for bolt connection.

[0017] More preferably, the mounting bracket includes a first mounting bracket disposed at the upper end of one side of the outer wall of the tank, a second mounting bracket disposed at the lower end of the other side of the outer wall of the tank, and a third mounting bracket disposed in the middle of the outer wall of the tank.

[0018] More preferably, the desiccant comprises desiccant particles that adsorb water vapor in the air.

[0019] More preferably, the tank is a plastic tank, which serves as the outer shell, is lightweight and corrosion-resistant, and is used to support the internal structure.

[0020] More preferably, the thermally conductive metal liner is placed inside the tank, directly carrying the desiccant and providing a highly thermally conductive path.

[0021] More preferably, the metal thermally conductive liner is designed as a pluggable module and installed inside the tank, allowing it to be removed separately for desiccant replacement.

[0022] More preferably, the thermally conductive metal liner is connected to the tank body via a snap-fit ​​structure.

[0024] More preferably, the flexible electric heating film is attached to the surface of the metal liner, achieving rapid and uniform heating through direct thermal contact.

[0025] More preferably, the upper end of the tank is provided with reinforcing ribs to enhance the structural strength and rigidity of the drying tank.

[0026] Preferably, the drying tank can be used for compressed air drying and adsorbent heating and regeneration in vehicle air suspension systems.

[0027] More preferably, the drying canister can be applied to vehicle air brake system dryers, commercial vehicle compressed air purification devices, and other vehicle gas treatment equipment that requires heating and desorption of adsorbents.

[0028] The drying can of this utility model includes a plastic can body, a heating film element, a metal heat-conducting liner placed inside the can body, and a metal heat-conducting baffle fixed inside the liner. Desiccant particles are filled in multiple fan-shaped chambers formed by the baffle. Felt is provided inside the upper and lower end caps to support the desiccant.

[0029] In this invention, by setting a metal liner inside the plastic drying can and adding a heat-conducting baffle inside the liner, the desiccant filling cavity is divided into multiple sector-shaped chambers, which can construct an efficient heat conduction path and effectively solve the problem of uneven heat transfer in traditional heating films; at the same time, it ensures that the desiccant in each sector-shaped chamber is heated evenly, significantly improving the desorption efficiency; in addition, the metal liner can directly support the desiccant, reducing the thermal stress on the plastic shell, thereby extending the overall service life of the can.

[0030] In this invention, the heating film is attached to the surface of the metal liner and transfers heat through direct contact, which can significantly shorten the heating time of the desiccant and achieve rapid desorption; at the same time, the heat can be evenly transferred to each sector-shaped chamber, effectively avoiding the problems of local overheating or insufficient desorption that are prone to occur in traditional heating films.

[0031] In this invention, a heat-conducting baffle divides the internal space of the metal heat-conducting liner into multiple sector-shaped chambers, each independently filled with desiccant. On one hand, the partition structure allows for uniform heat distribution among the chambers; on the other hand, it restricts the free movement of desiccant particles, preventing blockages caused by particle displacement and improving equipment durability. Furthermore, this design facilitates modularization, allowing for flexible adjustment of the number of sector-shaped chambers according to tank specifications, significantly enhancing equipment adaptability.

[0032] In this invention, the heating film can heat up rapidly after being energized, and once desorption is complete, the metal liner and heat-conducting baffle can dissipate heat quickly. This not only allows for desiccant regeneration in a short time, effectively improving system operating efficiency, but also reduces the impact of residual high temperature on the plastic shell, ensuring equipment safety. At the same time, it improves the recycling efficiency of the desiccant, further extending the overall service life of the drying tank.

[0033] In use, this utility model involves installing the desiccant in the air supply circuit of a vehicle's air suspension system. Compressed air output from the compressor enters the fan-shaped chamber of the desiccant through the air inlet, where the desiccant absorbs moisture from the compressed air. The treated compressed air then flows out through the air outlet. When the desiccant reaches saturation, the heating film element is activated by the control system to heat and desorb the desiccant. After desorption is complete, heating is stopped, and the desiccant quickly returns to room temperature thanks to the rapid heat dissipation characteristics of the metal liner and heat-conducting baffle. Subsequently, the desiccant can be reused in the air suspension system, achieving the recycling and regeneration of the desiccant.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] (1) The vehicle air suspension drying can provided by this utility model is designed to solve the problems of low thermal conductivity, uneven heating and slow heat dissipation of traditional drying cans by setting a metal heat-conducting liner in the can body, attaching a heating film element to the outer wall of the liner, and dividing the liner into multiple fan-shaped cavities by using multiple metal heat-conducting baffles. This structural design can significantly improve the overall thermal conductivity, heating uniformity and heat dissipation speed of the drying can, and optimize the desiccant regeneration effect.

[0036] (2) In this utility model, through the synergistic structure of “metal thermally conductive inner liner + attached heating film + metal thermally conductive partition”, the heat generated by the heating film when it is powered on can be directly conducted through the inner liner and partition to be quickly and evenly transferred to each fan-shaped cavity, avoiding the problem of local heat accumulation or delayed transfer in the traditional heating method, realizing efficient and uniform heating of the desiccant in the cavity, and greatly improving the desorption efficiency.

[0037] (3) This utility model relies on the excellent thermal conductivity of the metal thermally conductive liner and the metal thermally conductive partition to quickly remove residual heat after the desiccant is desorbed. This solves the problem of slow heat dissipation of the drying tank in the prior art and the problem of the shell life or subsequent use being affected by residual high temperature. It can quickly restore the drying tank to normal temperature, shorten the regeneration cycle and protect the tank structure.

[0038] (4) In response to the problem that the desiccant in the traditional drying canister tends to concentrate on one side due to shaking under vehicle driving vibration environment, which affects the airflow distribution, reduces the heating effect, or even blocks the air passage, this utility model can effectively limit the displacement of desiccant particles by setting an independent fan-shaped receiving cavity, ensuring stable airflow and uniform heating effect, while avoiding the risk of air passage blockage and improving the stability and reliability of the equipment in vehicle scenarios.
