Problems solved by technology

At this time, the temperature of the air (downdraft) supplied to the evaporator tube is approximately the same as the temperature of the air flow after heat exchange with the evaporator tube, so effective heat exchange (heating of low-temperature liquefied gas) cannot be performed in the evaporator tube

no. 1 approach

[0020] refer to Figure 1 to Figure 4 A heat exchange system according to a first embodiment of the present invention will be described. This heat exchange system is a system that heats a low-temperature medium by exchanging heat with air between a low-temperature medium (low-temperature liquefied gas, intermediate medium, etc.) that is lower than air (atmosphere). In addition, this heat exchange system can be used to directly heat low-temperature liquefied gas with air, and can also be used to heat an intermediate medium in a so-called intermediate medium heat exchange system (a device that uses an intermediate medium such as propane to heat low-temperature liquefied gas).

[0021] Such as Figure 1 to Figure 3 As shown, the heat exchange system includes along one direction ( figure 1 An odd number (three in this embodiment) of heat exchange components 101 and 102 are arranged in the left and right direction).

[0022] Hereinafter, among the odd number of heat exchange ass...

[0047] Next, refer to Figure 5 to Figure 7 A heat exchange system according to a second embodiment of the present invention will be described. In addition, in the second embodiment, only the parts different from those of the first embodiment will be described, and the description of the same configuration, operations, and effects as those of the first embodiment will be omitted.

[0048] The heat exchange system of the present embodiment includes an even number (four in the present embodiment) of heat exchange modules 111 and 121 arranged in one direction. In this embodiment, the heat exchange components 111 and 121 are arranged at equal intervals along one direction.

[0049] Hereinafter, among the plurality of heat exchange components 111, 121, they are arranged on one side of the system center plane Ps in one direction ( Figure 5 The heat exchange components on the right side of ) are called "one side component 111", and the plurality of heat exchange components 111, 12...

Abstract

A heat-exchange unit that is provided with at least one heat-exchange device (20) and with a deflection member (201) is provided. The heat-exchange device (20) is provided with a blower (30) that forms a downwardly flowing airflow, with a heat exchanger (40) that heats a low-temperature medium by performing a heat exchange between the airflow and the low-temperature medium, which is at a lower temperature than the air, and with a support part (50) that supports the heat exchanger (40) in a position that is above the ground. The deflection member (201) deflects the airflow such that, between the heat exchanger (40) and the ground, at least one portion of the airflow includes a component that is horizontal.

Description

technical field [0001] The invention relates to a heat exchange component and a heat exchange system. Background technique [0002] Conventionally, there is known an air-temperature type gasification apparatus that heats and vaporizes low-temperature liquefied gas such as liquefied natural gas (LNG) with air (atmosphere). For example, a low-temperature liquefied gas vaporization device (heat exchange device) is disclosed in Patent Document 1, which includes: an external air suction fan that generates a downdraft; vaporized evaporating tubes; and a stand supporting the evaporating tubes at a position away from the ground. [0003] In the low-temperature liquefied gas vaporization device described in Patent Document 1, the low-temperature air (air located on the downstream side of the evaporator pipe in the downdraft) cooled by contacting the evaporator pipe may be sucked again by the outside air suction fan. . Specifically, the air flow formed by the outside air suction fa...
