DETAILED DESCRIPTION

[0036] The utility model will be further described in detail below in combination with the drawings and preferred embodiments.

[0037] Embodiment 1: as shown in the figure, the vehicle-mounted cryogenic liquid vaporization mechanism in the vehicle-mounted cryogenic storage tank comprises: a vaporizer 1, a liquid phase output pipeline 3 in communication with the liquid phase in the cryogenic storage tank 2 and provided with a liquid output control valve 31, the liquid phase output pipeline 3 is connected with the vaporizer 1, and the vaporizer 1 is connected with a vaporization output pipeline. Figure 1

[0038] ​The vaporizer 1 is provided with two groups of heat exchange pipes, which are a first group of heat exchange pipes 11 and a second group of heat exchange pipes 12, and the input ends of the first group of heat exchange pipes 11 and the second group of heat exchange pipes 12 are communicated with the liquid phase output pipeline 3. The vaporization output pipeline includes two paths, which are a first vaporization output pipeline 4 and a second vaporization output pipeline 5. In the embodiment, the output end of the first group of heat exchange pipes 11 is communicated with the first vaporization output pipeline 4, and the output end of the second group of heat exchange pipes 12 is communicated with the second vaporization output pipeline 5.

[0039] In order to facilitate the pipeline connection, one end of the shell of the vaporizer 1 is provided with a shell cryogenic liquid phase inlet 105, and the other end of the shell of the vaporizer 1 is provided with two shell vaporization outlets, which are a first shell vaporization outlet 106 and a second shell vaporization outlet 107. The liquid phase output pipeline 3 is connected to the shell cryogenic liquid phase inlet 105, and the input ends of the two groups of heat exchange pipes are communicated with the liquid phase output pipeline 3 through the shell cryogenic liquid phase inlet 105. The output ends of the two groups of heat exchange pipes are communicated with the two shell vaporization outlets, respectively, and the two shell vaporization outlets are connected with the two paths of vaporization output pipelines, specifically, the output end of the first group of heat exchange pipes 11 is connected with the first shell vaporization outlet 106, and the first shell vaporization outlet 106 is connected with the first vaporization output pipeline 4; the output end of the second group of heat exchange pipes 12 is connected with the second shell vaporization outlet 107, and the second shell vaporization outlet 107 is connected with the second vaporization output pipeline 5.

[0040] In the embodiment, the first vaporization output pipeline 4 outputs the vaporization product of the cryogenic liquid after vaporization for use by the engine.

[0041] The second vaporization output pipeline 5 is communicated with the gas phase in the cryogenic storage tank 2, and the second vaporization output pipeline 5 is provided with a pump 6 and a gas phase control valve 51. In the embodiment, in order to facilitate the monitoring of the gas phase pressure in the cryogenic storage tank 2 and to facilitate automatic control, the second vaporization output pipeline 5 is further provided with a pressure sensor 501 for monitoring the gas phase pressure in the cryogenic storage tank 2.

[0042] In addition, in order to prevent the medium temperature from being too low to damage the pump 6, the second vaporization output pipeline 5 on the input end side of the pump 6 is provided with a pump input temperature sensor 601. Once the temperature signal monitored by the pump input temperature sensor 601 shows that the medium temperature is lower than the limit temperature that the pump can withstand, the pump 6 stops working, which can effectively avoid damage to the pump 6 caused by the too low medium temperature.

[0043] The vaporizer 1 belongs to a kind of heat exchanger, the medium in shell side and the medium in tube side carry out heat exchange, to realize the vaporization of low temperature liquid. The shell of vaporizer 1 is provided with shell side medium import and shell side medium export. The medium in shell side is not limited in this embodiment, generally, the medium that can vaporize the cryogenic liquid in the first group of heat exchange tube 11 and the second group of heat exchange tube 12 can be used.

[0044] The working principle is as follows: the liquid outlet control valve 31 is opened, the cryogenic liquid in the vehicle-mounted cryogenic storage tank 2 is heated and vaporized in the first group of heat exchange tube 11 in the vaporizer 1 through the liquid phase output pipeline 3, and the vaporized vapor is output outward through the first group of heat exchange tube 11, the first vaporization output pipeline 4 and used as the fuel of the engine.

[0045] When the pressure signal monitored by the pressure sensor 501 shows that the gas phase pressure in the cryogenic storage tank 2 is lower than the set value, it indicates that the gas phase in the cryogenic storage tank 2 needs to be pressurized, at this time, the gas phase control valve 51 is opened, the cryogenic liquid in the vehicle-mounted cryogenic storage tank 2 enters the first group of heat exchange tube 11 in the vaporizer 1 through the liquid phase output pipeline 3, and also enters the second group of heat exchange tube 12. The cryogenic liquid in the second group of heat exchange tube 12 is heated and vaporized, and then enters the gas phase in the cryogenic storage tank 2 under the pumping action of the pump 6, thereby realizing the pressurization of the gas phase in the cryogenic storage tank 2. When the pressure signal monitored by the pressure sensor 501 shows that the gas phase pressure in the cryogenic storage tank 2 reaches the set value, the pump stops working and the gas phase control valve 51 is closed. During the gas phase pressurization process, the rotation speed of the pump 6 can be adjusted to realize the adjustment of the gas phase pressurization speed. For example, increasing the rotation speed of the pump 6 can greatly shorten the gas phase pressurization time, thereby realizing the rapid pressurization of the gas phase.

[0046] As shown in Figure 1 , a vehicle-mounted cryogenic liquid fuel supply system adopts the vaporization mechanism of cryogenic liquid in the vehicle-mounted cryogenic storage tank described above. The cryogenic liquid fuel can be liquefied natural gas.

[0047] As can be seen from the above, the embodiment provides a vaporization mechanism of cryogenic liquid in a vehicle-mounted cryogenic storage tank and a vehicle-mounted cryogenic liquid fuel supply system. The input ends of the two groups of heat exchange tubes in the vaporizer 1 in the vaporization mechanism and the fuel supply system are communicated with one liquid phase output pipeline 3. Compared with the traditional vaporization mechanism, the pipeline structure is simplified and the manufacturing cost is effectively reduced. At the same time, the rotation speed of the pump 6 can be adjusted to realize the adjustment of the gas phase pressurization speed, which can greatly shorten the time required for gas phase pressurization, thereby realizing the rapid pressurization of the gas phase and effectively improving the pressurization efficiency.

[0048] Embodiment 2: as shown in Figure 2As shown, the vaporization mechanism of the cryogenic liquid in the vehicle-mounted cryogenic tank comprises a vaporizer 1, a liquid phase output pipeline 3 with a liquid output control valve 31 connected with the liquid phase in the cryogenic tank 2, the liquid phase output pipeline 3 is connected with the vaporizer 1, and the vaporizer 1 is connected with a vaporization output pipeline. The cryogenic liquid in the cryogenic tank 2 is output through the vaporization output pipeline after being vaporized in the vaporizer 1.

[0049] The vaporizer 1 is provided with two groups of heat exchange pipes, which are a first group of heat exchange pipes 11 and a second group of heat exchange pipes 12, and the input ends of the first group of heat exchange pipes 11 and the second group of heat exchange pipes 12 are communicated with the liquid phase output pipeline 3. The vaporization output pipeline comprises two paths, which are a first vaporization output pipeline 4 and a second vaporization output pipeline 5. In this embodiment, the output end of the first group of heat exchange pipes 11 is communicated with the first vaporization output pipeline 4, and the output end of the second group of heat exchange pipes 12 is communicated with the second vaporization output pipeline 5.

[0050] In order to facilitate pipeline connection, one end of the shell of the vaporizer 1 is provided with a shell cryogenic liquid phase inlet 105, and the other end of the shell of the vaporizer 1 is provided with two shell vaporization outlets, which are a first shell vaporization outlet 106 and a second shell vaporization outlet 107. The liquid phase output pipeline 3 is connected to the shell cryogenic liquid phase inlet 105, and the input ends of the two groups of heat exchange pipes are communicated with the liquid phase output pipeline 3 through the shell cryogenic liquid phase inlet 105. The output ends of the two groups of heat exchange pipes are communicated with the two shell vaporization outlets, and the two shell vaporization outlets are connected with the two vaporization output pipelines, specifically, the output end of the first group of heat exchange pipes 11 is connected with the first shell vaporization outlet 106, and the first shell vaporization outlet 106 is connected with the first vaporization output pipeline 4; the output end of the second group of heat exchange pipes 12 is connected with the second shell vaporization outlet 107, and the second shell vaporization outlet 107 is connected with the second vaporization output pipeline 5.

[0051] In this embodiment, the first vaporization output pipeline 4 outputs the vaporization product of the vaporized cryogenic liquid for engine use.

[0052] The second vaporization output pipeline 5 is communicated with the liquid phase in the cryogenic tank 2, and the second vaporization output pipeline 5 is provided with a pump 6. The second vaporization output pipeline 5 is provided with a liquid phase backflow control valve 51.

[0053] In this embodiment, in order to better monitor the temperature of the liquid phase in the cryogenic tank 2, the liquid phase output pipeline 3 is provided with a liquid phase temperature sensor 301 for monitoring the temperature of the liquid phase in the cryogenic tank 2.

[0054] In order to prevent the pump 6 from being damaged by low temperature, a pump input temperature sensor 601 is arranged on the second vaporization output pipeline 5 at the input side of the pump 6. Once the temperature signal monitored by the pump input temperature sensor 601 shows that the medium temperature is lower than the limit temperature that the pump can bear, the pump 6 stops working, which can effectively avoid the damage of the pump 6 caused by too low medium temperature.

[0055] Similarly, the vaporizer 1 belongs to a kind of heat exchanger, and the medium in shell side exchanges heat with the medium in tube side, so as to realize the vaporization of low temperature liquid. The shell of the vaporizer 1 is provided with shell side medium inlet and shell side medium outlet. The medium in shell side is not limited in the embodiment, and generally any medium that can vaporize the cryogenic liquid in the first group of heat exchange tubes 11 and the second group of heat exchange tubes 12 can be used.

[0056] The working principle is as follows: the outlet control valve 31 is opened, the cryogenic liquid in the vehicle-mounted cryogenic storage tank 2 enters the first group of heat exchange tubes 11 in the vaporizer 1 through the liquid phase output pipeline 3 to be heated and vaporized, and the vaporized vapor is output outward through the first group of heat exchange tubes 11, the first vaporization output pipeline 4 and used as fuel for the engine.

[0057] When the liquid phase in the cryogenic storage tank 2 needs to be saturated, the liquid phase reflux control valve 51 is opened, the cryogenic liquid in the vehicle-mounted cryogenic storage tank 2 enters the first group of heat exchange tubes 11 in the vaporizer 1 through the liquid phase output pipeline 3 and also enters the second group of heat exchange tubes 12. The cryogenic liquid in the second group of heat exchange tubes 12 is heated and vaporized, and then enters the liquid phase in the cryogenic storage tank 2 through the second vaporization output pipeline 5 under the pumping action of the pump 6, so as to realize the saturation of the liquid phase in the cryogenic storage tank 2, until the liquid phase and the gas phase in the cryogenic storage tank 2 return to the saturated vapor pressure state. Since the liquid phase temperature sensor 301 for monitoring the temperature of the liquid phase in the cryogenic storage tank 2 is arranged on the liquid phase output pipeline 3, once the temperature signal monitored by the liquid phase temperature sensor 301 shows that the temperature of the liquid phase in the cryogenic storage tank 2 exceeds the set range value, the saturation process is also stopped to prevent the temperature of the liquid phase in the cryogenic storage tank 2 from being too high and the evaporation from being too fast, which leads to the imbalance of gas and liquid. During the above saturation process, the speed of saturation can also be adjusted by adjusting the rotating speed of the pump 6, such as increasing the rotating speed of the pump 6 to speed up the saturation speed, so as to effectively improve the saturation efficiency.

[0058] As shown in Figure 2 A vehicle-mounted cryogenic liquid fuel supply system adopts the vaporization mechanism of the cryogenic liquid in the vehicle-mounted cryogenic storage tank with the above structure. The cryogenic liquid fuel can be liquefied natural gas.

[0059] As can be seen from the above, this embodiment provides a vaporization mechanism for cryogenic liquid in an on-board cryogenic storage tank and an on-board cryogenic liquid fuel supply system. The input ends of the two sets of heat exchange tubes in the vaporizer 1 of both the vaporization mechanism and the fuel supply system are connected to a liquid phase output pipeline 3. Compared with traditional vaporization mechanisms, the pipeline structure is simplified, and manufacturing costs are effectively reduced. Simultaneously, the saturation speed can be adjusted by changing the pump speed, thereby achieving rapid saturation and effectively improving saturation efficiency.

The liquid phase output pipeline 3 is connected to the vaporizer 1, and the vaporizer 1 is connected to a vaporization output pipeline. The cryogenic liquid in the cryogenic storage tank 2 is vaporized in the vaporizer 1 and then output through the vaporization output pipeline. In this embodiment, in order to better monitor the temperature of the liquid phase in the cryogenic storage tank 2, a liquid phase temperature sensor 301 for monitoring the temperature of the liquid phase in the cryogenic storage tank 2 is installed on the liquid phase output pipeline 3.

[0061] The vaporizer 1 is equipped with two sets of heat exchange tubes, namely a first set of heat exchange tubes 11 and a second set of heat exchange tubes 12. The input ends of both sets of heat exchange tubes 11 and 12 are connected to the liquid phase output pipeline 3. The vaporization output pipeline includes two paths, namely a first vaporization output pipeline 4 and a second vaporization output pipeline 5. In this embodiment, the output end of the first set of heat exchange tubes 11 is connected to the first vaporization output pipeline 4, and the output end of the second set of heat exchange tubes 12 is connected to the second vaporization output pipeline 5.

Specifically, the output end of the first set of heat exchange tubes 11 is connected to the first vaporization outlet 106, and the first vaporization outlet 106 is connected to the first vaporization output pipeline 4; the output end of the second set of heat exchange tubes 12 is connected to the second vaporization outlet 107, and the second vaporization outlet 107 is connected to the second vaporization output pipeline 5.

[0063] In this embodiment, the first vaporization output pipeline 4 outputs the vaporized product of the cryogenic liquid for use by the engine.

[0064] The second vaporization output pipeline 5 is connected with both the gas phase and the liquid phase in the cryogenic storage tank 2, and the second vaporization output pipeline 5 is provided with a pump 6. In order to prevent the pump 6 from being damaged at low temperature, the second vaporization output pipeline 5 on the input end side of the pump 6 is provided with a pump input temperature sensor 601. Once the temperature signal monitored by the pump input temperature sensor 601 shows that the medium temperature is lower than the limit temperature that the pump can withstand, the pump 6 stops working to avoid damage to the pump 6 caused by too low medium temperature.

[0065] The second vaporization output pipeline 5 is divided into two routes after the output end of the pump 6, one route being a gas phase return pipeline 51 and the other route being a liquid phase return pipeline 52. The gas phase return pipeline 51 is connected with the gas phase in the cryogenic storage tank 2, and the liquid phase return pipeline 52 is connected with the liquid phase in the cryogenic storage tank 2. The gas phase return pipeline 51 is provided with a gas phase control valve 511, and the liquid phase return pipeline 52 is provided with a liquid phase return control valve 521. In the embodiment, in order to facilitate monitoring of the gas phase pressure in the cryogenic storage tank 2 and automatic control, the gas phase return pipeline 51 is further provided with a pressure sensor 501 for monitoring the gas phase pressure in the cryogenic storage tank 2.

[0066] In order to facilitate connection and control, the gas phase return pipeline 51, the liquid phase return pipeline 52 and the second vaporization output pipeline 5 are connected through a three-position three-way electromagnetic valve 7.

[0067] Similarly, the vaporizer 1 belongs to a kind of heat exchangers, and the medium in the shell side exchanges heat with the medium in the tube side, so as to realize the vaporization of low-temperature liquid. The shell of the vaporizer 1 is provided with a shell medium inlet and a shell medium outlet. In the embodiment, the medium in the shell is not limited, and generally any medium that can vaporize the cryogenic liquid in the first group of heat exchange tubes 11 and the second group of heat exchange tubes 12 can be used.

[0068] The working principle is as follows: the outlet control valve 31 is opened, and the cryogenic liquid in the vehicle-mounted cryogenic storage tank 2 enters the first group of heat exchange tubes 11 in the vaporizer 1 to be heated and vaporized, and the vaporized vaporization product is output outward through the first group of heat exchange tubes 11 and the first vaporization output pipeline 4 to be used as fuel for the engine.

[0069] When the pressure signal monitored by the pressure sensor 501 shows that the gas phase pressure in the cryogenic tank 2 is lower than the set value, it means that the gas phase in the cryogenic tank 2 needs to be pressurized. At this time, the gas phase control valve 511 is opened, and the three-way electromagnetic valve 7 is opened to the state of communicating with the gas phase return pipeline 51. The cryogenic liquid in the vehicle-mounted cryogenic tank 2 enters the first group of heat exchange pipes 11 in the vaporizer 1 and simultaneously enters the second group of heat exchange pipes 12 through the liquid phase output pipeline 3. The cryogenic liquid in the second group of heat exchange pipes 12 is vaporized by heating, and under the pumping action of the pump 6, it enters the gas phase in the cryogenic tank 2 through the gas phase return pipeline 51, thereby realizing the pressurization of the gas phase in the cryogenic tank 2. When the pressure signal monitored by the pressure sensor 501 shows that the gas phase pressure in the cryogenic tank 2 reaches the set value, the pump 6 stops working, and the gas phase control valve 51 is closed. During the gas phase pressurization process, the speed of the gas phase pressurization can be adjusted by changing the speed of the pump 6. For example, increasing the speed of the pump 6 can shorten the time of the gas phase pressurization, thereby realizing the rapid pressurization of the gas phase.

[0070] When the liquid phase in the cryogenic tank 2 needs to be saturated pressurized, the liquid phase return control valve 521 is opened, and the three-way electromagnetic valve 7 is opened to the state of communicating with the liquid phase return pipeline 52. The cryogenic liquid in the vehicle-mounted cryogenic tank 2 enters the second group of heat exchange pipes 12 in the vaporizer 1 through the liquid phase output pipeline 3. The cryogenic liquid in the second group of heat exchange pipes 12 is vaporized by heating, and under the pumping action of the pump 6, it enters the liquid phase in the cryogenic tank 2 through the liquid phase return pipeline 52, thereby realizing the saturation of the liquid phase in the cryogenic tank 2, until the liquid phase and the gas phase in the cryogenic tank 2 return to the saturated vapor pressure state. Since the liquid phase temperature sensor 301 for monitoring the temperature of the liquid phase in the cryogenic tank 2 is arranged on the liquid phase output pipeline 3, once the temperature signal monitored by the liquid phase temperature sensor 301 shows that the temperature of the liquid phase in the cryogenic tank 2 exceeds the set range value, the saturation is also stopped to prevent the temperature of the liquid phase in the cryogenic tank 2 from being too high and the evaporation from being too fast, resulting in the imbalance of the gas and liquid. Similarly, changing the speed of the pump 6 can realize the adjustment of the saturation speed. Increasing the speed of the pump can greatly speed up the saturation speed, thereby greatly improving the saturation efficiency.

[0071] As shown in Figure 3 A vehicle-mounted cryogenic liquid fuel supply system adopting the above-mentioned structure of the cryogenic liquid vaporization mechanism in the vehicle-mounted cryogenic tank. The cryogenic liquid fuel can be liquefied natural gas.

[0072] As can be seen from the above, this embodiment provides a vaporization mechanism for cryogenic liquid in an on-board cryogenic storage tank and an on-board cryogenic liquid fuel supply system. The input ends of the two sets of heat exchange tubes in the vaporizer 1 of both the vaporization mechanism and the fuel supply system are connected to a liquid phase output pipeline 3. Compared with traditional vaporization mechanisms, the pipeline structure is simplified, and manufacturing costs are effectively reduced. Furthermore, the vaporization mechanism for cryogenic liquid in an on-board cryogenic storage tank and the on-board cryogenic liquid fuel supply system described in this embodiment integrate gas-phase pressurization and liquid-phase saturation, which further simplifies the pipeline structure of the entire vaporization mechanism and fuel supply system. Simultaneously, the speed of gas-phase pressurization and liquid-phase saturation can be adjusted by changing the pump speed, which can greatly shorten the gas-phase pressurization time or the liquid-phase saturation time, effectively improving the efficiency of gas-phase pressurization and liquid-phase saturation, and achieving rapid gas-phase pressurization and rapid liquid-phase saturation.

[0073] Example 4: Figure 4 As shown, this embodiment differs from Embodiment 3 in that a control valve assembly is provided between the gas phase reflux pipeline 51, the liquid phase reflux pipeline 52, and the second vaporization output pipeline 5. This control valve assembly can switch between three connection states: the second vaporization output pipeline 5 connected to the gas phase reflux pipeline 51, the second vaporization output pipeline 5 connected to the liquid phase reflux pipeline 52, and the liquid phase reflux pipeline 52 connected to the gas phase reflux pipeline 51. A gas phase reflux pipeline vaporizer 512 is also provided on the gas phase reflux pipeline 51. In this embodiment, the gas phase reflux pipeline vaporizer 512 is an ambient temperature vaporizer.

[0074] The control valve assembly can take many forms, as long as it enables the three connection methods mentioned above between the second vaporization output line 5, the gas phase return line 51, and the liquid phase return line 52. For example, the gas phase return line 51, the liquid phase return line 52, and the second vaporization output line 5 are connected, and on / off control valves for controlling the on / off state are respectively installed at the pipe ends of the connection points of the gas phase return line 51, the liquid phase return line 52, and the second vaporization output line 5. That is, three independent on / off control valves are used to control the on / off state to achieve the control and switching of the three connection states mentioned above.

[0075] In order to save cost and simplify pipeline in the embodiment, the control valve assembly comprises a valve block 71, the gas phase reflux pipeline 51, the liquid phase reflux pipeline 52 and the second vaporization output pipeline 5 are connected with the valve block 71, the valve block 71 can switch and control three communication states, the three communication states comprise: the second vaporization output pipeline 5 and the gas phase reflux pipeline 51 are in communication state, the second vaporization output pipeline 5 and the liquid phase reflux pipeline 52 are in communication state, the liquid phase reflux pipeline 52 and the gas phase reflux pipeline 51 are in communication state. In order to save energy consumption, in the embodiment, the position where the liquid phase reflux pipeline 52 is connected with the cryogenic liquid storage tank 2 ensures that, in the state where the liquid phase reflux pipeline 52 and the gas phase reflux pipeline 51 are in communication, the pressure difference between the liquid phase reflux pipeline 52 and the gas phase reflux pipeline 51 can make the cryogenic liquid in the cryogenic liquid storage tank 2 enter the gas phase reflux pipeline vaporizer 512 through the liquid phase reflux pipeline 52 to be vaporized, and the generated vaporization object flows into the cryogenic liquid storage tank 2 through the gas phase reflux pipeline 51. In the production process of the equipment, the liquid phase reflux pipeline 52 is connected with the cryogenic liquid storage tank 2 as low as possible, so that there is enough pressure difference even in the case of a large drop in liquid level. The valve block 71 can adopt a four-position three-way electromagnetic valve.

[0076] The working principle is as follows: when the automobile engine is working, the liquid outlet control valve 31 is opened, the cryogenic liquid in the vehicle-mounted cryogenic liquid storage tank 2 enters the first group of heat exchange pipes 11 in the vaporizer 1 to be heated and vaporized through the liquid phase output pipeline 3, and the vaporized vaporization object is output outward through the first group of heat exchange pipes 11 and the first vaporization output pipeline 4 to be used as fuel for the engine.

[0077] When the pressure signal monitored by the pressure sensor 501 shows that the gas phase pressure in the cryogenic liquid storage tank 2 is lower than the set value, it indicates that the gas phase in the cryogenic liquid storage tank 2 needs to be pressurized, at this time, the gas phase control valve 511 is opened, and the valve block 71 is switched to the state where the second vaporization output pipeline 5 and the gas phase reflux pipeline 51 are in communication. The cryogenic liquid in the vehicle-mounted cryogenic liquid storage tank 2 enters the first group of heat exchange pipes 11 and the second group of heat exchange pipes 12 in the vaporizer 1 through the liquid phase output pipeline 3. The cryogenic liquid in the second group of heat exchange pipes 12 is heated and vaporized, and then enters the gas phase reflux pipeline vaporizer 512 through the gas phase reflux pipeline 51 under the pumping action of the pump 6 to be further vaporized, and the vaporization object generated in the gas phase reflux pipeline vaporizer 512 enters the gas phase in the cryogenic liquid storage tank 2, thereby realizing the pressurization of the gas phase in the cryogenic liquid storage tank 2.

[0078] In the gas phase pressurization process, the rotation speed of the pump 6 can be changed to adjust the gas phase pressurization speed, for example, increasing the rotation speed of the pump 6 to shorten the gas phase pressurization time, thereby realizing the rapid pressurization of the gas phase.

[0079] When the liquid phase in the cryogenic tank 2 needs to be saturated pressurized, the liquid phase return control valve 521 is opened, and the valve block 71 is switched to the state that the second vaporization output pipeline 5 is in communication with the liquid phase return pipeline 52. The cryogenic liquid in the vehicle-mounted cryogenic tank 2 enters the second group of heat exchange pipes 12 in the vaporizer 1 through the liquid phase output pipeline 3. The cryogenic liquid in the second group of heat exchange pipes 12 is vaporized by heating, and then enters the liquid phase in the cryogenic tank 2 through the liquid phase return pipeline 52 under the pumping action of the pump 6, so as to realize the saturation of the liquid phase in the cryogenic tank 2, until the liquid phase and the gas phase in the cryogenic tank 2 return to the saturated vapor pressure state. Since the liquid phase temperature sensor 301 for monitoring the temperature of the liquid phase in the cryogenic tank 2 is arranged on the liquid phase output pipeline 3, once the temperature signal monitored by the liquid phase temperature sensor 301 shows that the temperature of the liquid phase in the cryogenic tank 2 exceeds the set range value, the saturation is also stopped to prevent the temperature of the liquid phase in the cryogenic tank 2 from being too high and the evaporation from being too fast, resulting in imbalance between gas and liquid. Similarly, by changing the speed of the pump 6, the saturation speed can be adjusted. Increasing the speed of the pump greatly speeds up the saturation speed, thereby greatly improving the saturation efficiency.

[0080] When the automobile engine is in a stopped working state, if the pressure signal monitored by the pressure sensor 501 shows that the gas phase pressure in the cryogenic tank 2 is lower than the set value, it means that the gas phase in the cryogenic tank 2 needs to be pressurized. At this time, the gas phase control valve 511 on the gas phase return pipeline 51 and the liquid phase return control valve 521 on the liquid phase return pipeline 52 are opened, and the valve block 71 is switched to the state that the liquid phase return pipeline 52 is in communication with the gas phase return pipeline 51. At this time, the cryogenic liquid in the cryogenic tank 2 can enter the gas phase return pipeline vaporizer 512 through the liquid phase return pipeline 52 and the gas phase return pipeline 51, and be vaporized in the gas phase return pipeline vaporizer 512. The vaporization product generated in the gas phase return pipeline vaporizer 512 enters the gas phase in the cryogenic tank 2, thereby pressurizing the gas phase in the cryogenic tank 2.

[0081] As shown in Figure 4 A vehicle-mounted cryogenic liquid fuel supply system adopts the vaporization mechanism of the cryogenic liquid in the vehicle-mounted cryogenic tank with the above structure. The cryogenic liquid fuel can be liquefied natural gas.

[0082] As can be seen from the above, this embodiment provides a vaporization mechanism for cryogenic liquid in a vehicle-mounted cryogenic storage tank and a vehicle-mounted cryogenic liquid fuel supply system. In this embodiment, a vaporizer 512 is added to the vapor phase return pipeline 51. The control valve assembly can switch between the states of the second vaporization output pipeline 5 connected to the vapor phase return pipeline 51, the second vaporization output pipeline 5 connected to the liquid phase return pipeline 52, and the liquid phase return pipeline 52 connected to the vapor phase return pipeline 51. Compared with embodiment 3, this embodiment adds a connection state where the liquid phase return pipeline 52 is connected to the vapor phase return pipeline 51. In this state, the cryogenic storage tank 2 can be pressurized by vapor phase even when the car engine is not running.

[0083] Example 5: Figure 5 As shown, this embodiment differs from Embodiment 3 in that a bypass vaporization pipeline 8 with a bypass control valve 81 is connected between the gas phase reflux pipeline 51 and the liquid phase reflux pipeline 52, and a bypass vaporizer 82 is installed on the bypass vaporization pipeline 8. In this embodiment, the bypass vaporizer 82 is an ambient temperature vaporizer. To save energy, the connection position between the liquid phase reflux pipeline 52 and the cryogenic storage tank liquid 2 ensures that, with the bypass control valve 91 open, the pressure difference between the liquid phase reflux pipeline 52 and the gas phase reflux pipeline 51 allows the cryogenic liquid in the cryogenic storage tank 2 to vaporize in the bypass vaporizer 82 via the liquid phase reflux pipeline 52 before entering the cryogenic storage tank 2.

[0084] The working principle is as follows: To simplify the description, the working process of the same parts as in Example 3 will not be repeated.

[0085] When the car engine is off, if the pressure signal monitored by the pressure sensor 501 indicates that the gas phase pressure in the cryogenic storage tank 2 is lower than the set value, it means that the gas phase in the cryogenic storage tank 2 needs to be pressurized. At this time, the bypass control valve 81 on the bypass vaporization line is opened, and the gas phase control valve 511 on the gas phase return line 51 and the liquid phase return control valve 521 on the liquid phase return line 52 are also open, while the three-position three-way solenoid valve 7 is closed. At this time, the cryogenic liquid in the cryogenic storage tank 2 can enter the bypass vaporizer 82 in the bypass vaporization line 8 through the liquid phase return line 52 and vaporize. The vaporized product generated in the bypass vaporizer 82 enters the gas phase in the cryogenic storage tank 2 through the gas phase return line 51, thereby pressurizing the gas phase of the cryogenic storage tank 2.

[0086] like Figure 5 As shown, an on-board cryogenic liquid fuel supply system employs a vaporization mechanism for cryogenic liquid in an on-board cryogenic storage tank with the aforementioned structure. The cryogenic liquid fuel can be liquefied natural gas.

[0087] From the above, the embodiment provides a kind of vaporization mechanism of deep cooling liquid in vehicle-mounted deep cooling tank and a kind of vehicle-mounted deep cooling liquid fuel supply system.The embodiment is relative to embodiment 3, gas phase return line 51 and liquid phase return line 52 are connected with bypass control valve 81 between bypass vaporization line 8, bypass vaporization line 8 is provided with bypass vaporization device 82, therefore, when automobile engine does not work, gas phase pressurization in deep cooling tank 2 can also be realized.

[0088] In the premise of embodiment 1 or embodiment 2 or embodiment 3 or embodiment 4 or embodiment 5, the vehicle-mounted deep cooling tank deep cooling liquid vaporization mechanism described in the embodiment, the shell side medium inlet of the shell of the vaporizer 1 is the engine coolant inlet 101, the shell side medium outlet of the shell of the vaporizer 1 is the engine coolant outlet 102, the engine coolant inlet 101 and the engine coolant outlet 102 are both in communication with the inside of the shell of the vaporizer 1, the engine coolant inlet 101 is provided on the shell of the vaporizer 1 at the input end side of the heat exchange pipe, and the engine coolant outlet 102 is provided on the shell of the vaporizer 1 at the output end side of the heat exchange pipe; the engine coolant inlet 101 and the engine coolant outlet 102 are respectively used for connecting with the engine coolant input pipe 15 and the engine coolant output pipe 16. The engine coolant, which is heated in the engine, enters the inside of the shell of the vaporizer 1 through the engine coolant inlet 101 on the shell of the vaporizer 1 for cooling, and the cooled engine coolant is output through the engine coolant outlet 102 and the engine coolant output pipe 16 for engine cooling. The engine coolant is also called engine antifreeze coolant, and the conventional engine coolant mainly contains ethylene glycol and water.

[0089] In the embodiment, the engine coolant inlet 101 and the engine coolant outlet 102 are provided on the shell of the vaporizer 1, the engine coolant used for engine refrigeration absorbs heat from the engine and increases in temperature, and the engine coolant, which is heated, enters the inside of the shell of the vaporizer 1 through the engine coolant inlet 101, thereby providing heat energy for the vaporization of the deep cooling liquid in the heat exchange pipe in the vaporizer.

[0090] A kind of vehicle-mounted deep cooling liquid fuel supply system, which adopts the above-mentioned structure of the vaporization mechanism of deep cooling liquid in vehicle-mounted deep cooling tank.

[0091] For simplicity of illustration, the shell of the vaporizer 1 with the engine coolant inlet 101 and the engine coolant outlet 102 is only shown in Figure 1The vaporization mechanism of the cryogenic liquid in the vehicle-mounted cryogenic liquid tank and the vehicle-mounted cryogenic liquid fuel supply system described in Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, and Embodiment 5 can all use the vaporizer 1 with the shell-side medium inlet and the shell-side medium outlet being the engine coolant inlet 101 and the engine coolant outlet 102, that is, the vaporizer 1 in the vehicle-mounted cryogenic liquid tank and the vehicle-mounted cryogenic liquid fuel supply system described in Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, and Embodiment 5, in which the heat exchange medium in the shell side of the vaporizer 1 can be the engine coolant.

[0092] As can be seen from the above, in this embodiment, the vaporizer 1 of the vehicle-mounted cryogenic liquid tank and the vehicle-mounted cryogenic liquid fuel supply system described in Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4, and Embodiment 5 has the engine coolant inlet 101 and the engine coolant outlet 102 on the shell, that is, the heat exchange medium in the shell of the vaporizer 1 is the engine coolant, which makes full use of the heat energy of the engine coolant whose temperature has risen after cooling the engine, thereby effectively saving energy and avoiding waste of heat energy. After the engine coolant cools the engine, the temperature of the engine coolant usually rises to 90℃±5℃, therefore, making full use of the heat energy of the engine coolant after the temperature rises can effectively reduce the vaporization cost.

[0093] Embodiment 7: On the premise of Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4 or Embodiment 5, the vaporization mechanism of the cryogenic liquid in the vehicle-mounted cryogenic liquid tank described in this embodiment has the shell-side medium inlet on the shell of the vaporizer 1 being the temperature control medium inlet 103, and the shell-side medium outlet being the temperature control medium outlet 104, both of which are in communication with the inside of the shell of the vaporizer 1, the temperature control medium inlet 103 is arranged on the shell of the vaporizer 1 at the input end side of the heat exchange pipe, and the temperature control medium outlet 104 is arranged on the shell of the vaporizer 1 at the output end side of the heat exchange pipe. The temperature control medium inlet 103 and the temperature control medium outlet 104 are respectively connected with the temperature control medium output pipeline 13 and the temperature control medium input pipeline 14 in the vehicle-mounted temperature control system. The temperature control medium for adjusting the temperature in the vehicle-mounted temperature control system enters the inside of the shell of the vaporizer 1 through the temperature control medium output pipeline 13 and the temperature control medium inlet 103 on the vaporizer 1, exchanges heat with the cryogenic liquid in the heat exchange pipe in the vaporizer 1, and then is output from the temperature control medium outlet 104 on the vaporizer 1 and the temperature control medium input pipeline 14 for temperature adjustment of the vehicle-mounted temperature control system.

[0094] A vehicle-mounted cryogenic liquid fuel supply system using the above-mentioned structure of the vaporization mechanism of the cryogenic liquid in the vehicle-mounted cryogenic liquid tank.

[0095] A vehicle-mounted temperature control system based on the above-mentioned vaporization mechanism of the cryogenic liquid in the vehicle-mounted cryogenic storage tank, the vehicle-mounted temperature control system comprising a temperature control medium output pipeline 13 and a temperature control medium input pipeline 14, the output end of the temperature control medium output pipeline 13 being connected with the temperature control medium inlet 103 on the shell of the vaporizer 1, and the input end of the temperature control medium input pipeline 14 being connected with the temperature control medium outlet 104 on the shell of the vaporizer 1. The output end of the temperature control medium output pipeline 13 is provided with a check valve 131 to prevent the temperature control medium in the shell of the vaporizer 1 from flowing back into the temperature control medium output pipeline 13 from the temperature control medium inlet 103.

[0096] The vehicle-mounted temperature control system described in the present embodiment comprises a vehicle-mounted air conditioner and / or a vehicle-mounted refrigerator and / or a vehicle-mounted freezer that use the cold energy released by the temperature control medium completely or incompletely for refrigeration. The temperature control medium that has been cooled after heat exchange with the cryogenic liquid in the heat exchange tube in the vaporizer 1 is returned to the vehicle-mounted temperature control system from the temperature control medium outlet 104 on the vaporizer 1 and the temperature control medium input pipeline 14 for cooling, such as refrigeration for the vehicle-mounted air conditioner, refrigeration or freezing for the vehicle-mounted refrigerator, and refrigeration or freezing for the vehicle-mounted freezer. The temperature control medium that has been warmed after releasing the cold energy is introduced into the shell of the vaporizer 1 from the temperature control medium inlet 103 on the vaporizer 1 through the temperature control medium output pipeline 13 to be cooled again. The composition of the temperature control medium in the vehicle-mounted temperature control system mainly comprises ethylene glycol and water.

[0097] During the gas phase pressurization process or the liquid phase saturation process, by adjusting the rotating speed of the pump 6 on the second vaporization output pipeline 5, not only can the gas phase pressurization speed or the saturation speed be adjusted, but also the outlet temperature of the temperature control medium outlet 104 can be adjusted to meet the temperature requirements of the corresponding vehicle-mounted temperature control system. Increasing the rotating speed of the pump 6 can not only speed up the gas phase pressurization speed or the saturation speed, but also can realize rapid cooling or rapid refrigeration of the vehicle-mounted temperature control system.

[0098] For simplicity of illustration, the shell side medium inlet and the shell side medium outlet are the shell structure of the vaporizer 1 with the temperature control medium inlet 103 and the temperature control medium outlet 104, respectively, which are only shown in Figure 2 The vaporization mechanism of the cryogenic liquid in the vehicle-mounted cryogenic storage tank and the vehicle-mounted cryogenic liquid fuel supply system described in Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4 or Embodiment 5 can also use the structure of the vaporizer 1, that is, the temperature control medium in the vehicle-mounted temperature control system can be used as the heat exchange medium in the shell side of the vaporizer 1.

[0099] From the above, the embodiment provides a vaporization mechanism of deep-cooling liquid in a vehicle-mounted deep-cooling liquid tank, a vehicle-mounted deep-cooling liquid fuel supply system, and a vehicle-mounted temperature control system. The heat exchange medium in the casing of the vaporizer 1 uses the temperature control medium in the vehicle-mounted temperature control system, which makes full use of the cold energy released in the deep-cooling liquid vaporization process, including the process of deep-cooling liquid vaporization for engine use and / or the process of deep-cooling liquid vaporization followed by gas phase pressurization and / or the process of deep-cooling liquid vaporization followed by liquid phase saturation, thereby effectively avoiding waste of cold energy. The temperature control medium in the vehicle-mounted temperature control system is used for refrigeration after obtaining cold energy by heat exchange with the deep-cooling liquid in the vaporizer 1, which greatly reduces the energy consumption required by the vehicle-mounted temperature control system and effectively reduces the cost of using the vehicle-mounted temperature control system, such as vehicle-mounted air conditioner, vehicle-mounted refrigerator, and vehicle-mounted cold cabinet.

[0100] In the premise of the embodiment 1 or the embodiment 2 or the embodiment 3 or the embodiment 4 or the embodiment 5, the embodiment provides a vaporization mechanism of deep-cooling liquid in a vehicle-mounted deep-cooling liquid tank. The casing medium inlet on the casing of the vaporizer 1 includes an engine cooling liquid inlet 101 and a temperature control medium inlet 103, and the casing medium outlet on the casing includes an engine cooling liquid outlet 102 and a temperature control medium outlet 104. The engine cooling liquid inlet 101, the engine cooling liquid outlet 102, the temperature control medium inlet 103, and the temperature control medium outlet 104 are all in communication with the inside of the casing of the vaporizer 1. The engine cooling liquid inlet 101 and the temperature control medium inlet 103 are arranged on the casing of the vaporizer 1 at the input end side of the heat exchange pipe, and the engine cooling liquid outlet 102 and the temperature control medium outlet 104 are arranged on the casing of the vaporizer 1 at the output end side of the heat exchange pipe. The engine cooling liquid inlet 101 and the engine cooling liquid outlet 102 are respectively connected with the engine cooling liquid input pipe 15 and the engine cooling liquid output pipe 16.

[0101] The engine cooling liquid and the temperature control medium are the same medium. The engine cooling liquid is also called engine antifreeze cooling liquid. The conventional engine cooling liquid mainly contains ethylene glycol and water.

[0102] The engine cooling liquid after cooling the engine has a temperature usually increased to 90℃±5℃, enters the inside of the casing of the vaporizer 1 through the engine cooling liquid inlet 101 on the casing of the vaporizer 1, and the temperature control medium for adjusting temperature in the vehicle-mounted temperature control system enters the inside of the casing of the vaporizer 1 through the temperature control medium inlet 103 on the vaporizer 1, and the engine cooling liquid is mixed with the temperature control medium. The medium in the casing of the vaporizer 1 exchanges heat with the deep-cooling liquid in the heat exchange pipe, and the heat energy of the engine cooling liquid is fully released. The medium in the inside of the casing of the vaporizer 1 is output through the engine cooling liquid outlet 102 for cooling the engine, and the medium in the inside of the casing is output through the temperature control medium outlet 104 for temperature adjustment of the vehicle-mounted temperature control system.

[0103] A vehicle-mounted deep-cooled liquid fuel supply system using the above-mentioned deep-cooled liquid vaporization mechanism of the vehicle-mounted deep-cooled tank.

[0104] The vehicle-mounted temperature control system comprises a temperature control medium output pipeline 13 and a temperature control medium input pipeline 14, the output end of the temperature control medium output pipeline 13 is connected with the temperature control medium inlet 103 on the casing of the vaporizer 1, and the input end of the temperature control medium input pipeline 14 is connected with the temperature control medium outlet 104 on the casing of the vaporizer 1. The output end of the temperature control medium output pipeline 13 is provided with a check valve 131 to prevent the temperature control medium in the casing of the vaporizer 1 from flowing back into the temperature control medium output pipeline 13 from the temperature control medium inlet 103.

[0105] The vehicle-mounted temperature control system described in the embodiment comprises a vehicle-mounted air conditioner and / or a vehicle-mounted refrigerator and / or a vehicle-mounted cooler which are completely or incompletely temperature-regulated by the temperature control medium.

[0106] The temperature of the engine coolant outlet 102 and the temperature control medium outlet 104 can be adjusted and set according to the temperature required by the vehicle-mounted temperature control system. For example, increasing the rotating speed of the pump 6 to increase the flow of the deep-cooled liquid into the second heat exchange tube group and / or reducing the flow of the engine coolant in the engine coolant inlet 101 can correspondingly reduce the temperature of the temperature control medium outlet 104. For example, reducing the rotating speed of the pump 6 to reduce the flow of the deep-cooled liquid into the second heat exchange tube group and / or increasing the flow of the engine coolant in the engine coolant inlet 101 can correspondingly increase the temperature of the temperature control medium outlet 104.

[0107] In order to simplify the illustration, the casing structure of the vaporizer 1 in which the shell side medium inlets include the engine coolant inlet 101 and the temperature control medium inlet 103, and the shell side medium outlets include the engine coolant outlet 102 and the temperature control medium outlet 104 is schematically shown in Figure 3 、 Figure 4 、 Figure 5 The deep-cooled liquid vaporization mechanism of the vehicle-mounted deep-cooled tank described in Embodiment 1, Embodiment 2, Embodiment 3, Embodiment 4 and Embodiment 5 and a vehicle-mounted deep-cooled liquid fuel supply system can all use the vaporizer 1 of the above-mentioned structure, i.e., the engine coolant and the temperature control medium of the vehicle-mounted temperature control system can both be used as the heat exchange medium in the shell side.

[0108] From the above, the embodiment provides a vaporization mechanism of deep-cooled liquid in a vehicle-mounted deep-cooled liquid tank, a vehicle-mounted deep-cooled liquid fuel supply system, and a vehicle-mounted temperature control system. The vaporization mechanism of deep-cooled liquid in a vehicle-mounted deep-cooled liquid tank and the vehicle-mounted deep-cooled liquid fuel supply system have simple structure and high integration. The heat exchange medium in the shell of the vaporizer 1 uses engine coolant and temperature control medium in the vehicle-mounted temperature control system. The heat energy generated during the operation of the automobile engine is fully utilized, and the cold energy released during the deep-cooled liquid vaporization process is also fully utilized.
