LNG automobile air conditioner exchanger controllable in water quantity and water temperature

Abstract

The invention provides an LNG automobile air conditioner exchanger controllable in water quantity and water temperature. A plurality of cavities with the two ends being sealed are combined in parallel to form a whole, a pipeline in each cavity extends out of the cavity in a penetrating mode to form a pipe I and a pipe II, the two ends of each cavity are provided with a port I and a port II respectively, and the pipe II and the port I of the cavity I serve as a water outlet and a gas inlet respectively. The connecting mode of the cavity I and the cavity II is that the pipe I of the cavity I is connected with the port I of the cavity II in series, and the port II of the cavity I is connected with the pipe I of the cavity II in series. The pipe II of the cavity III is connected with the pipe I of the cavity II in series, the port I of the cavity III is connected with the port II of the cavity II in series, for the rest cavities, the ports I are connected with the ports II correspondingly, the pipes I are connected with the pipes II correspondingly, the port II at the tail end serves as a water inlet, and the pipe I at the tail end servers as a gas outlet. A branch port I is additionally formed in the end face of the cavity II. LNG enters the exchanger, cold energy recovery can be conducted on the LNG with the low temperature being -150 DEG C, heat exchange is conducted through internal circulating water, the circulating water is circulated through a water pump, and refrigeration is conducted immediately after the circulating water flows through the exchanger.

Description

technical field [0001] The invention relates to the recovery and utilization of the cold energy released during the gasification of LNG liquefied natural gas, and supports the air conditioner to achieve the cooling purpose, and is used for energy exchange, in particular to an LNG automobile air conditioner exchanger with controllable water volume and water temperature. Background technique [0002] The LNG industry started in the 1980s. Due to the two oil crises and the discovery of more natural gas resources, people realized that natural gas is a cleaner and more efficient energy source than oil. The huge resource consumption and environmental pollution problems are gradually being paid attention to by people, so the utilization of natural gas resources has been developed rapidly. [0003] The key component of the LNG liquefied natural gas vehicle air conditioning system is the cold recovery heat exchanger. At present, when the cold energy released during natural gas gasif...

Problems solved by technology

The manufacturing cost of this structure is relatively high, not only to prevent the air leakage of the cast aluminum body, but also to prevent the air leakage of the end pipe welding. If there is an air leak in one place of the cast aluminum body, the whole is scrapped, so the cost is relatively high
