Problems solved by technology

[0006] However, the heat exchange effect of this improved heat exchanger will still be affected by the temperature and humidity of the external natural wind, and the influence is very large.
Especially in hot and humid areas, the cooling effect of this heat exchanger is still poor, and the energy consumption is very large, making it more and more difficult to meet the cooling demand

Embodiment 1

[0044] Such as figure 2 As shown, in Embodiment 1 of the present invention, the flash-type closed heat exchanger includes a closed shell 101, which is rectangular in shape, surrounded by a plate structure, and has an accommodating chamber inside. The bottom of the accommodation chamber is provided with a water atomization device 102, and the water atomization device 102 sprays the atomized water produced into the accommodation chamber from bottom to top; the top of the accommodation chamber is provided with a negative pressure fan 103, and the negative pressure fan 103 Continuously discharge the gas in the closed casing 101 out of the closed casing 101 to form a uniform and stable negative pressure environment in the containing chamber. Preferably, the exhaust air volume of the negative pressure fan 103 is greater than the evaporation of the atomized water in the closed casing 101. On the one hand, the steam in the closed casing 101 can be fully discharged to improve the evap...

Embodiment 2

[0048] Such as image 3 As shown, in the second embodiment of the present invention, the flash type closed heat exchanger includes a closed shell 201, which is rectangular in shape, surrounded by a plate structure, and has an accommodating chamber inside. The top of the accommodation chamber is provided with a water atomization device 202, and the water atomization device 202 sprays atomized water into the accommodation chamber from top to bottom; The blower 203, the negative pressure blower 203 continuously discharges the gas in the closed casing 201 out of the closed casing 201, so that a uniform and stable negative pressure environment is formed in the containing chamber. Preferably, the exhaust air volume of the negative pressure fan 203 is greater than the evaporation rate of the atomized water in the closed casing 201. On the one hand, the steam in the closed casing 201 can be fully discharged to improve the evaporation efficiency of the atomized water. On the one hand,...

Embodiment 3

[0056] In Embodiment 3 of the present invention, the flash type closed heat exchanger includes a closed casing 301, one side of the closed casing 301 is provided with a water atomization device 302, and the other side is provided with a negative pressure fan 303, and the closed casing 301 is provided with a water atomization device 302. 301 is equipped with a heat exchange device, the heat exchange device is located between the water atomization device 302 and the negative pressure fan 303, a first static pressure chamber is formed between the negative pressure fan 303 and the heat exchange device, the water atomization device 302 and the heat exchange device A second static pressure chamber is formed between the heating devices, and the negative pressure fan 303 forms a negative pressure environment in the second static pressure chamber, and the water atomization device 302 sprays atomized water into the second static pressure chamber to make the atomization Water evaporates i...

Abstract

The invention discloses a flashing type closed heat exchanger. A closed shell is included and provided with a negative-pressure draught fan. The negative pressure environment is formed in the closed shell through the negative-pressure draught fan. A water atomization device is arranged in the closed shell and sprays atomized water into the closed shell so that the atomized water can be evaporatedinto steam in the negative pressure environment. According to the flashing type closed heat exchanger, evaporation of the atomized water is promoted in the closed negative pressure environment, the integral temperature in the closed environment is reduced, the effect of refrigeration is achieved, and influences from the temperature and humidity of natural wind are avoided. The equipment installedcapacity is small, and the occupied space is small. In the refrigeration process, no heat is exhausted into the atmosphere, the heat island effect cannot be generated, the refrigeration efficiency ishigh, and the effect is stable and reliable.

Description

technical field [0001] The invention relates to a heat exchanger, in particular to a flash type closed heat exchanger. Background technique [0002] A heat exchanger is a device used to exchange heat between cold and hot media, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In actual production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used . [0003] Existing heat exchangers usually include an open cavity, in which a heat exchange coil is arranged, a large amount of low-temperature outdoor natural wind enters the open cavity, and absorbs the heat of the heat exchange coil when passing through the heat exchange coil , into high-temperature air, discharged out of the cavity, so as to achieve the cooling effect on the medium in the heat exchange coil. [0004] The problem with this traditional air-cooled heat ...
