The sterilization module 3 includes a pulse light source 33, and the pulse light source 33 is configured to output pulsed strong light to sterilize at least the airflow in the air duct 200a.

Therefore, the pulse light source 33 of the sterilization module 3 is controlled to release the pulse strong light, the pulse strong light can cause great damage to the microorganisms such as bacteria, the activity of the enzymes in the pulse strong light is reduced, even the DNA and RNA structures of the pulse strong light are damaged, and finally the microorganisms such as bacteria are killed; moreover, the pulse light source 33 outputs intense white light in a pulse form to at least irradiate the air in the air duct 200a, so as to achieve the effect of killing bacteria, and in the sterilization process, the air does not need to be heated, so that the energy consumption of the sterilization module 3 is reduced, and the use cost of a user is reduced.

The pulsed intense light comprises multi-spectrum light, including ultraviolet light, infrared light, visible light and the like, wherein the ultraviolet light has an important effect on sterilization, and the infrared light also has a synergistic sterilization effect, so that the sterilization module 3 has a good sterilization effect and sterilization efficiency, the sterilization capability of the sterilization module 3 is convenient to ensure, and the energy consumption of the sterilization module 3 is further reduced; the ultraviolet light in the pulse highlight can destroy the genetic material of microorganism such as bacterium and lead to the bacterium death, can make bacterium rapid heating up lead to the bacterium to dewater and die through the infrared light in the pulse highlight, can destroy bacterium protein structure through pulse flash effect, high penetrability and the high impact of the visible light in the pulse highlight for protein denaturation leads to the bacterium death.

According to the heat exchange assembly 100 provided by the embodiment of the utility model, the sterilization module 3 is arranged at least at one of the two opposite ends of the heat exchanger 1, so that the integration arrangement of the heat exchange assembly 100 and the sterilization module 3 is convenient to realize, the functions of the heat exchange assembly 100 are enriched, and meanwhile, when the heat exchange assembly 100 is used for the air conditioner 200, the production cost of the air conditioner 200 is saved, and the universality of the heat exchange assembly 100 is improved; in addition, the pulse light source 33 of the module 3 that disinfects can release high intensity light to reach the effect of disinfecting, make the module 3 that disinfects have good sterilization efficiency and bactericidal effect, for ultraviolet sterilization, the module 3 that disinfects of this application can disappear to more kinds of microorganisms, can practice thrift the sterilization time, and the module 3 energy consumption that disinfects simultaneously is lower, and can not accelerate the ageing of working of plastics.

Compared with some technologies, ultraviolet sterilization has photosynthesis, and photochemical action is the main sterilization mechanism of ultraviolet sterilization, and refers to optical reaction generated when microorganisms are irradiated by light with specific wavelength; when the genetic information of the double helix in microorganisms such as bacteria is irradiated by ultraviolet light, partial m-diazabenzene and isomers of m-diazabenzene are formed, and the substance can cause the metabolic function of the microorganism itself to be obstructed and cause the inheritance of the microorganism to be problematic until the microorganism dies.

The strong pulse light has a photo-thermal sterilization mechanism, and the photo-thermal action refers to that the temperature rise is generated after the light energy is absorbed by substances; when the microorganism receives the pulse intense light irradiation in a short distance, the surface temperature of the microorganism can be rapidly increased due to the absorption of a large amount of light energy in a short time, the surface structure can be thoroughly destroyed and die, and the irradiated object can not generate temperature rise due to the very short whole photothermal action process. Therefore, the pulse strong light adopting the photo-thermal sterilization mechanism can effectively kill all microorganisms.

Therefore, as shown in the following table, the pulse strong light sterilization also covers the ultraviolet band compared with the ultraviolet light sterilization, so the pulse strong light also has a photochemical sterilization mechanism; however, the mechanism of photochemical sterilization is only assisted by the intense pulse light, and ultraviolet rays hardly penetrate a dense cell wall structure of microorganisms such as molds and spores, and DNA substances cannot absorb the ultraviolet rays, so that the sterilization efficiency of ultraviolet ray sterilization is low compared to the intense pulse light.
