Problems solved by technology
At this time, the air (atmosphere around the heat exchanger) whose temperature has been lowered by the influence of the airflow (low temperature air) after heat exchange in the heat exchanger is supplied to the heat exchanger, so that the heat exchange cannot be effectively performed. Heat exchange (heating of low temperature medium)
In addition, since the wind direction changes every moment, the heat exchanger whose heat exchange efficiency becomes low according to the wind direction also changes.

Embodiment Construction
[0020] refer to Figure 1 to Figure 11 A heat exchange module according to one embodiment of the present invention will be described. The heat exchange component is a device for heating the low-temperature medium by exchanging heat with the low-temperature medium (low-temperature liquefied gas, intermediate medium, etc.) that is lower than the air (atmosphere). In addition, the heat exchange assembly can be used to directly heat low-temperature liquefied gas with air, and can also be used to heat intermediate medium in so-called intermediate medium heat exchange assembly (a device that uses an intermediate medium such as propane to heat low-temperature liquefied gas).
[0021] like Figure 1 to Figure 3 As shown, the heat exchange assembly includes a plurality of heat exchange devices 20 and a control unit 70 . In addition, in figure 1 In , illustration of the control unit 70 is omitted. The respective heat exchange devices 20 have the same shape as each other.

A heat exchange assembly includes assembly constituent elements and a control part (70). The component component has a plurality of heat exchange devices (20), and each heat exchange device (20) has a blower (30) and a heat exchanger (40). The control unit (70) includes: a reinhalation determination unit (72) for determining whether reinhalation of low-temperature air is occurring; a wind direction determination unit (74) for determining a wind direction; and when the reinhalation determination unit (72) determines that reinhalation is occurring , the air volume control unit (76) that performs one-way control, wherein the one-way control adjusts the speed of each air blower (30) in the following manner, that is: based on the speed of the air blower (30) of the upwind device and the speed of the air blower (30) of the downwind device ( The difference or ratio of the rotating speed of 30) indicates a direction inclination greater than that in a stable state, and the rotating speed of the blower (30) gradually increases from the downwind device to the upwind device.
Description
technical field [0001] The invention relates to a heat exchange component. Background technique [0002] Conventionally, there is known an air-to-air heat exchange device that heats and vaporizes a low-temperature medium (liquefied natural gas, etc.) that is lower than air by using air (atmosphere). For example, Patent Document 1 discloses a low-temperature liquefied gas vaporizer (heat exchange unit) equipped with an evaporator for evaporating an intermediate medium by exchanging heat with air and an intermediate medium that is lower than air, and a heating device for heating the low-temperature liquefied gas. ). The evaporator has a blower for forming a vertical airflow, and a heat exchanger for heating the intermediate medium by exchanging heat between the intermediate medium and the airflow. Likewise, the warming device has a blower for forming a vertical airflow and a heat exchanger for heating the low-temperature liquefied gas by exchanging heat with the airflow. ...
