Problems solved by technology
However, when applied to such moving conditions as automobile engines, the chemical adsorption refrigeration system still faces long-term bumps and tilts of the adsorption bed, unstable heat source temperature and flow rate, and little cooling water. The outdoor road environment temperature is high, and the cooling water temperature is difficult to effectively drop Specific problems, especially due to the lack of cooling water and the many impurities in the flue gas of automobile engines, if the conventional water seal structure is still used, the cooling water will become sludge water in a short period of time, and its impurities will seriously affect the normal operation of the system pipeline valves , leading to system failure

Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0027] The purpose of the present invention is to focus on solving the separation of smoke and water passages and improving the cooling of the chemical adsorption refrigeration system using high-temperature engine exhaust as the cooling heat source. Key issues such as water cooling conditions.
[0028] The present invention first needs to redesign the structure of the chemical adsorption bed. The original chemical adsorption refrigeration system adopts a cylindrical sealed tube structure, and its flue gas and cooling water rely on the surface area of the outer wall of the unit tube of the adsorption bed to participate in heat exchange. The cooling water channels share the same inner cavity space. The purpose of the present invention is to separate the flue gas channel from the cooling water channel, specifically refer to figure 1 ...

The invention discloses a chemical adsorption refrigeration system driven by engine tail gas of a vehicle. A chemical adsorption bed therein is set to be an annular structure, the separation between a smoke passage and a water passage in the chemical adsorption bed is effectively realized, and circulation water is kept clean without being polluted by chimney spot and without blocking pipeline valves of the refrigeration system; in addition, redesign is performed aiming at a vehicle-mounted cooling tower structure working under a bumping moving condition, so the chemical adsorption refrigeration system driven by the engine tail gas of the vehicle has the effects of small size, compact structure, high evaporation efficiency, dedusting, deslagging and the like.
Description
technical field [0001] The invention relates to an automobile refrigeration system, in particular to a chemical adsorption refrigeration system driven by exhaust gas from an automobile engine. Background technique [0002] In the prior art, the chemical adsorption refrigeration system using engine exhaust gas as energy is based on a water seal structure, and achieves the purpose of indirectly controlling the connection and disconnection of the flue gas passage by controlling the water valve. Under relatively stable working conditions and relatively sufficient cooling water, the water seal structure can well realize its smoke-water switching control function. However, when applied to such moving conditions as automobile engines, the chemical adsorption refrigeration system still faces long-term bumps and tilts of the adsorption bed, unstable heat source temperature and flow rate, and little cooling water. The outdoor road environment temperature is high, and the cooling water...
