Embodiment
The utility model is described in further detail with reference to specific embodiment.
As shown in figure 1, a kind of frost-cracking-preventing Fresh air handing unit of the present utility model, including with air intake vent 11 and air outlet
12 casing 1, is sequentially provided with filter 2, hot-water coil pipe 3 and blower fan 4 in casing 1 from air intake vent 11 to air outlet 12, in casing 1
The three-dimensional heat exchange of heat pipe 5 to move in circles is additionally provided with, three-dimensional heat exchange of heat pipe 5 includes the condensation positioned at the inlet air side of hot-water coil pipe 3
Section 51 and the evaporator section 52 positioned at the air side of hot-water coil pipe 3, condensation segment 51 are connected with evaporator section 52 by pipeline 53.Three-dimensional heat pipe
Heat exchanger 5 forms a U-shaped structure for surrounding the both sides of hot-water coil pipe 3.Refrigerant is marked with the pipe of three-dimensional heat exchange of heat pipe 5, such as
HFC-134a or alternative chlorofluoro carbon etc., with the suction heat release of refrigerant, it can be produced not between condensation segment 51 and evaporator section 52
Need the self-loopa of additional energy.After Fresh air handing unit starts, blower fan 4 makes air be sucked from air intake vent 11, from air outlet 12
Discharge, in this process, air can first pass through the filtration, purification of filter 2, then be changed by hot-water coil pipe 3 and three-dimensional heat pipe
The heating of hot device 5, bulk temperature gradually rises air in this process.Because evaporator section 52 is located at the air side of hot-water coil pipe 3
High temperature gas flow in, so the higher air of temperature is understood some heat and is transferred in the refrigerant of evaporator section 52, steam refrigerant
Hair, then enters condensation segment 51 by pipeline 53, then low-temperature airflow is exchanged heat, refrigerant condenses and returns to evaporator section
52, i.e., the effect of fresh air preheating is generated using the transport properties of three-dimensional heat exchange of heat pipe 5.So fresh air and hot-water coil pipe 3
The temperature difference will be obviously reduced, which achieves the bursting by freezing problem that hot-water coil pipe 3 is prevented on the premise of energy consumption is not increased, compared to
Electrical heating pre-heating device more saves naturally.
Three-dimensional heat exchange of heat pipe 5 is made up of one or more loop.Because use environment is different, three-dimensional heat pipe is changed
The heat exchange demand of hot device 5 is also different, so the loop structure of three-dimensional heat exchange of heat pipe 5 also can be different, light circuit is not individual
Number, pipe row can also change according to actual needs.
Filter 2 is one or more of combinations in roughing efficiency air filter, medium effeciency filter, high efficiency particulate air filter.It is because right
The requirement of air quality is different, and the selection to filter 2 also can be different, if not high to air quality requirements, can only use
Roughing efficiency air filter is a kind of, as desired raising can change medium effeciency filter, high efficiency particulate air filter even roughing efficiency air filter, middle effect into
The combination of filter, high efficiency particulate air filter.
As depicted in figs. 1 and 2, casing 1 is the interior double-decker for filling out insulation material 13.Because Fresh air handing unit is quick
Change the equipment of air themperature, so casing 1 is inside and outside always to have the obvious temperature difference, casing can be weakened by insulation material 13
Heat transfer inside and outside 1, improve energy utilization rate.Insulation material 13 can select the materials such as fire-retardant high density polyurathamc.
The inner layer material of casing 1 can use galvanized steel plain sheet or stainless steel plate, and the cladding material of casing 1 can use color steel.
As depicted in figs. 1 and 2, the motor 6 for driving blower fan 4 is additionally provided with casing 1.Motor 6 is directly arranged in casing 1
It is compact.Blower fan 4 and form or direct connection form that motor 6 can be belt transmission, blower fan can be no spiral case wind
Machine or there is spiral case blower fan etc..
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of not departing from the utility model and creating design, various modifications and improvements can be made, these belong to this practicality
New protection domain.
