Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1 and 2, the embodiment of the present invention provides a bioaerosol detection device, which includes: casing 1, detection mechanism 11 and be used for the heat conduction mechanism 3 of 11 heat conductivities of detection mechanism, detection mechanism 11 sets up in the casing 1, heat conduction mechanism 3 sets up detection mechanism 11 with between the casing 1, heat conduction mechanism 3 with detection mechanism 11 with casing 1 connects.

Wherein, the shell is a closed cavity structure except the air outlet hole and the air inlet hole. The shell can be made of metal or plastic. The utility model discloses biological aerosol detection device can use but not limited to in the biological aerosol detection technology field, and biological aerosol detection device needs inclosed operational environment, and consequently fan heat dissipation commonly used can not satisfy biological aerosol detection device's sealed requirement. Along with the extension of operating time, a large amount of heat can gather inside bioaerosol detection device, and the high temperature environment leads to the circuit board of bioaerosol detection device inside to appear unstable phenomenon. Therefore, the utility model discloses bioaerosol detection device, at first set up the circuit board in sensor equipment and gas filtration equipment's top, the heat that produces the circuit board gathers at the top of casing under the effect of hot gas flow, gather between casing and circuit board promptly, prevent that the hot gas flow from encircleing sensor equipment and gas filtration equipment, improve sensor equipment's detection precision, the mode of heat transfer in airtight environment through the air current, derive the inside heat of bioaerosol detection device to the top of casing, heat conduction mechanism's setting, under the circumstances that guarantees bioaerosol detection device confined, derive the heat at bioaerosol detection device top, prevent that the impurity in the heat dissipation gas from influencing bioaerosol detection device's detection precision, improve bioaerosol detection device's radiating efficiency.
