Abstract
The invention discloses a refrigeration capacity recovery heat exchanger for a liquefied natural gas refrigerator wagon, and aims to provide a heat exchanger which can prevent gas congelation caused by directly exchanging latent heat or sensible heat of liquefied natural gas when refrigeration capacity released in the process of vaporizing the liquefied natural gas is recycled and is used for refrigeration of the refrigerator wagon, and has high heat exchange efficiency and a small size. The heat exchanger comprises a liquid inlet pipe, a vaporizer, a gas return pipe, a fin and a gravity assisted heat pipe, wherein one end of the vaporizer is communicated with the liquid inlet pipe, and the other end of the vaporizer is communicated with the gas return pipe; a condensation section of the gravity assisted heat pipe is arranged inside the vaporizer; and the fin is arranged on an evaporation section of the gravity assisted heat pipe. By the refrigeration capacity recovery heat exchanger for the liquefied natural gas refrigerator wagon, the congelation of gases such as water vapor, CO2 and the like in the air, which is caused by directly exchanging the latent heat or the sensible heat of the liquefied natural gas, is prevented while a large amount of refrigeration capacity which is released in the process of vaporizing the liquefied natural gas is recycled and is used for the refrigeration of the refrigerator wagon; and the heat exchanger has the high heat exchange efficiency and the small size and is suitable to be mounted on a vehicle.
Description
Technical field
Patent of the present invention relates to a kind of liquefied natural gas refrigeration car cold recovery exchanger.
Background technology
The critical component of liquefied natural gas refrigeration car cold recovery is a cold recovery exchanger.At present, the most of direct gasification formula heat exchanger that adopts of liquefied natural gas refrigeration car cold recovery exchanger, utilization be liquefied natural gas in heat exchanger direct gasification to the method for air released cold quantity.This heat exchanger heat exchange efficiency is low, needs bigger heat exchange area, makes heat exchanger volume excessive, is not easy to vehicle-mounted.And because the temperature of liquefied natural gas is-160 ℃, liquefied natural gas and air heat transfer temperature difference are huge, and this method can cause water in air steam, CO
2Deng freezing of gas, scars have stopped up heat exchanger again, make through the heat exchanger air quantity reduce, heat transfer resistance increases, the heat exchanger heat exchange efficiency descends.
Summary of the invention
The present invention is in order to overcome weak point of the prior art; Provide a kind of when reclaiming the cold that liquefied natural gas vaporization discharges and being used for the refrigerator car refrigeration; Can avoid utilizing latent heat or the sensible heat of liquefied natural gas directly to change the gas that causes into freezes; Heat exchange efficiency is high, the heat exchanger that volume is little.
Patent of the present invention realizes through following technical proposals:
A kind of liquefied natural gas refrigeration car cold recovery exchanger is characterized in that, comprises feed tube, gasifier, muffler, fin and gravity assisted heat pipe; Said gasifier one end is communicated with feed tube, and the other end is communicated with muffler, and it is inner that the condensation segment of said gravity assisted heat pipe is installed in said gasifier, and said fin is installed in the evaporator section of gravity assisted heat pipe.
The present invention has following technique effect:
1, liquefied natural gas refrigeration car cold recovery exchanger of the present invention has avoided utilizing the latent heat of liquefied natural gas or sensible heat directly to carry out water in air steam, the CO that heat exchange causes when the recovery liquefied natural gas vaporization discharges a large amount of colds and is used to freeze
2Deng freezing of gas, prevent that scars from stopping up heat exchanger, ensure air quantity and heat transfer resistance through heat exchanger, ensure the heat exchange efficiency of heat exchanger.
2, liquefied natural gas refrigeration car cold recovery exchanger of the present invention utilizes gravity assisted heat pipe to realize heat exchange, and heat exchange efficiency is high, and volume is little, is fit to vehicle-mounted.
Description of drawings
Fig. 1 is the sketch map of a kind of liquefied natural gas refrigeration of the present invention car cold recovery exchanger.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment patent of the present invention is elaborated.
The sketch map of a kind of liquefied natural gas refrigeration of the present invention car cold recovery exchanger is as shown in Figure 1, comprises feed tube 1, gasifier 2, muffler 3, fin 4 and gravity assisted heat pipe 5.Said gasifier 2 one ends are communicated with feed tube 1, and the other end is communicated with muffler 3, and the condensation segment of said gravity assisted heat pipe 5 is installed in said gasifier 2 inside, and said fin 4 is installed in the evaporator section of gravity assisted heat pipe 5.
Liquefied natural gas is got in the gasifier 2 by feed tube 1; Gravity assisted heat pipe condensation segment heat release heating liquefied natural gas makes it gasification, and gaseous natural gas is returned by muffler 3; The gravity assisted heat pipe evaporator section absorbs the air heat; Make air cooling, the cold of liquefied natural gas is transferred to air, discharge cold energy of liquefied natural gas through gravity assisted heat pipe 5.
