The specific implementation mode is as follows:
the present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1, the utility model discloses a novel warm braw core of hydroecium structure, including last hydroecium, the lower hydroecium, it includes last hydroecium master part 8 and upper water chamber cap 7 to go up the hydroecium, the lower hydroecium includes lower hydroecium master part 3 and lower water chamber cap 2, go up the hydroecium, set up a plurality of flat pipes 5 that dispel the heat between the lower hydroecium, the flat pipe socket of last hydroecium master part 8 that the flat pipe 5 upper ends that dispel the heat inserted the upper hydroecium, the flat pipe socket of the lower hydroecium master part 3 that dispel the heat inserted the lower hydroecium is gone up through flat pipe 5 intercommunication, the inside of lower hydroecium, be equipped with fin 6 between the flat pipe 5 that dispel the heat, the flat pipe 5 outside that dispel the heat sets up left side board 4, right side board 11, the upper water chamber tip sets up outlet pipe 10, the lower hydroecium tip sets up inlet tube 1.
When the automobile passenger cabin defrosting and demisting device works, high-temperature ethylene glycol water solution is introduced into the lower water chamber through the water inlet pipe 1, then is converged into the upper water chamber after being shunted by the heat dissipation flat pipes 5, and is finally discharged through the water outlet pipe 10, the heat dissipation flat pipes 5 are introduced with the high-temperature circulating ethylene glycol water solution, the heat of the ethylene glycol water solution is dissipated by the fins 6, and then is blown into the automobile passenger cabin from the inside of the air conditioning box through the air channels by the air blower, so that comfortable temperature is brought to passengers in the passenger cabin or the front windshield is defrosted and demisted.
Because the flat pipe 5 of right side part heat dissipation is close to outlet pipe 10, inlet tube 11, this partial flat pipe 5 flow of heat dissipation is bigger than normal, and the left side part is kept away from outlet pipe 10, inlet tube 11's flat pipe flow is little, and when the air current passed through flat pipe 5 of heat dissipation, it is higher to be close to the partial air current temperature of right side, and it is lower to be close to the partial temperature of left side, and this kind of phenomenon will lead to warm braw core air-out side surface temperature distribution inequality, and then makes the heat transfer performance of single core reduce.
In order to avoid the phenomenon, as shown in fig. 2, a guide plate 9 is arranged inside the upper water chamber and close to a water outlet pipe 10, the guide plate 9 divides the inside of the upper water chamber into a first cavity 12 and a second cavity 13, a plurality of guide holes 9-1 are arranged on the guide plate 9 at intervals, the first cavity 12 and the second cavity 13 are communicated through the guide holes 9-1, the right-side part heat dissipation flat pipe 5 is communicated with the second cavity 13, the left-side part heat dissipation flat pipe 5 and the middle part heat dissipation flat pipe 5 are communicated with the first cavity 12, and the first cavity 12 and the second cavity 13 are both communicated with the water outlet pipe 10. For the flat heat dissipation pipes 5 on the right side, after the ethylene glycol aqueous solution enters the second cavity 13 of the upper water chamber, the flow guide plate 9 plays a certain flow limiting role on the ethylene glycol aqueous solution, so that the flow of the ethylene glycol aqueous solution passing through the flat heat dissipation pipes 5 on the right side is limited, the flow of the ethylene glycol aqueous solution close to the flat heat dissipation pipes 5 on the left side is increased, and the temperature of the surface of the air outlet side of the warm air core tends to be consistent.
As shown in fig. 2 and 3, the guide plate 9 includes a plate body 9-2, the plate body 9-2 is disposed perpendicular to the flat heat dissipation pipe 5, a gap is left between the plate body 9-2 and the end of the flat heat dissipation pipe 5, a guide hole 9-1 is disposed in the plate body 9-2, the front end of the plate body 9-2 is close to the end of the upper water chamber, the rear end of the plate body 9-2 is bent toward one side of the flat heat dissipation pipe 5 to form a support body 9-3, and the support body 9-3 is disposed parallel to the flat heat dissipation pipe 5. When the water tank is installed, the plate body 9-2 and two side edges of the support body 9-3 are welded and fixed with the inner walls of the two sides of the upper water chamber, and the bottom edge of the support body 9-3 is welded and fixed with the bottom wall of the upper water chamber.
As shown in fig. 3 and 4, in this embodiment, the front half of the plate body 9-2 close to the water outlet pipe 10 is not provided with an opening, and the diversion hole 9-1 is disposed on the rear half of the plate body 9-2 far from the water outlet pipe 10. And the diversion holes 9-1 are different in size, and the diversion holes closer to the water outlet pipe 10 are smaller. The diversion holes 9-1 are strip-shaped, the width of all the diversion holes 9-1 is consistent, and the length of the diversion hole 9-1 which is closer to the water outlet pipe is smaller. By adopting the arrangement structure of the diversion holes 9-1, the problem of uneven flow distribution can be avoided for the heat dissipation flat pipe 5 on the right side part, namely, the flow of the glycol aqueous solution of the heat dissipation flat pipe 5 closer to the water outlet pipe 10 is larger.
The arrangement rule, the size and the spacing distance of the flow guide holes 9-1 can also be determined according to the fixed working condition of the hot air core body during actual working, if the inlet flow rate of the common hot air core body during working is 6L/min, CFD simulation analysis calculation needs to be carried out according to the flow rate of 6L/min, so that the flow rate distribution of each flat pipe is the most uniform. During calculation, the arrangement rule, the size and the spacing distance of the flow guide holes 9-1 need to be continuously adjusted, and finally the arrangement rule, the size and the spacing distance of the flow guide holes corresponding to the group of data with the most uniform flow distribution of the heat dissipation flat pipes are found out to be the final structure.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
