Description of the drawings
Fig. 1 is the sectional view of one embodiment of the utility model.
Fig. 2 is the vertical view of one embodiment PTC heater of the utility model.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments.
Referring to Fig. 1-Fig. 2, the changes in temperature conversion cabinet of the utility model, the body 1 including being internally provided with changes in temperature chamber 2, the changes in temperature chamber 2
Top is fixed with PTC heater 3 and the evaporation fan 4 positioned at 3 forepart of PTC heater, and 2 back of changes in temperature chamber is equipped with evaporation plate 5, steams
Hair plate 5 is located at 4 lower section of PTC heater 3 and evaporation fan, and 2 Inner Constitution of changes in temperature chamber is followed by evaporation fan 4, PTC heater
3 and the circulating air duct of evaporation plate 5.
Circulating air duct it is rational in infrastructure, hot-air or cold air can be made quickly and evenly to be transmitted to each inside changes in temperature chamber 2
A position reaches efficient heating or refrigeration effect, improves user experience, and changes in temperature conversion cabinet refrigeration utilizes evaporation plate 5, heating profit
With PTC heater 3, the effect of dual-use is realized.
Further, spaced layer between 2 back of the evaporation plate 5 and changes in temperature chamber, between evaporation plate 5 and changes in temperature chamber 2
Circulation air path is formed, the circulation air path of the present embodiment includes the first air duct 61 being located in wall and including 5 phase of evaporation plate
To the second air duct 62 of wall opposite side.During actual design, the second air duct 62 can be removed.
It includes the second air duct 62 of the 5 relative spacing layer opposite side of the first air duct 61 and evaporation plate being located in wall.
Hot-air or cold air enter from the top of evaporation plate 5, are then divided into two-way, flow through the first air duct 61, mistake all the way
Any bottom end (i.e. the bottom of changes in temperature chamber 2) dissipated and directly reach evaporation plate 5 will not occur in journey, ensure air through pervaporation
In the transmission process of plate 5, heat exchange is (i.e. temperature change is little) as small as possible, then is diffused upwards so as to full of entire changes in temperature
Chamber 2, ensure air can reach in 2 bottom of changes in temperature chamber and changes in temperature chamber 2 far from evaporation plate 5 each position, it is ensured that heating or
Refrigeration effect;Another way flows through the second air duct 62, and the second air duct 62 is directly connected with changes in temperature chamber 2, air along evaporation plate 5 to flow down
It moves and is diffused on the way inside changes in temperature chamber 2.
In conclusion most of position of changes in temperature chamber 2 can be transported to more quickly by flowing through the air in the second air duct 62, and flow
Air through the first air duct 61 can be transported at position of the changes in temperature chamber 2 far from the second air duct 62, and double air channel structures ensure hot-air
Or cold air can reach each position of changes in temperature chamber 2, ensure that the temperature difference of 2 various places inside of changes in temperature chamber is little, effectively avoid changes in temperature
Frosting or icing phenomenon occur for 2 inside of chamber, reduce the maintenance cost of user, improve user experience.
Further, the evaporation plate 5 extends downwardly but not in contact with to 2 bottom of changes in temperature chamber, circulating air duct spontaneous evaporation plate 5
Followed by 2 bottom of changes in temperature chamber, 2 forepart of changes in temperature chamber and 2 top of changes in temperature chamber and eventually enter into evaporation fan 4 and PTC heater 3.
Flowing through the air in the first air duct 61 and the second air duct 62 finally can reach 2 bottom of changes in temperature chamber, and before changes in temperature chamber 2
Converge in portion.
Further, several demarcation strips 7 are equipped in the changes in temperature chamber 2 from top to bottom, before demarcation strip 7 is located at evaporation plate 5
Side.
Further, the PTC heater 3 includes the fixed seat 31 of two or so distributions and is arranged between two fixed seats 31
Heat sink strip, heat sink strip includes upper fixinig plate 32, lower fixinig plate 33 and being arranged between fixinig plate 32 and lower fixinig plate 33
Corrugate fin 34, the pitch A of corrugate fin 34 are more than 6mm, and pitch A is more than common PTC heater, and pitch A can more than 6mm
Condensed water is effectively prevent to accumulate, avoids blocking air duct, condensed water can be effectively prevent in the corrugate fin 34 of PTC heater 3
Upper cohesion, effectively avoids the occurrence of the common practice of gambling.
Further, 2 top of changes in temperature chamber is fixed with wind scooper 8, and wind chamber, PTC are formed between wind scooper 8 and body 1
Heater 3 is located at wind intracavitary, and wind scooper 8 includes air inlet and air outlet, and evaporation fan 4 is fixed on the air inlet of wind scooper 8,
Air outlet ensures that air can flow through evaporation plate 5 and carry out heat exchange towards evaporation plate 5.
It is above disclosed to be only the preferred embodiment of the utility model rather than the utility model is limited with this
Claims according to the equivalent variations made in scope of protection of the utility model, still belong to what the utility model was protected
