According to the embodiment of the present invention, it is preferable that the body case 10 be entirely made of the phase change heat storage material, whereby the temperature control effect in the vehicle interior can be further improved. The inventors found that the heat exchange amount of the vehicle body to the outside is large, and taking a conventional automobile as an example, in a standing state, the vehicle body includes a body dash panel 16, a body front floor 17a, a body rear floor 17b, and a body ceiling 18, and the heat exchange performance for the passenger compartment is calculated as follows:
setting the inner space of the passenger cabin of the whole vehicle: 3032X 1477X 1392mm; passenger cabin related whole vehicle body area: ceiling (without panoramic sunroof): s=1.18m 2 Vehicle body floor: s=3.35m2, dash panel: s=0.95 m2.
Environmental conditions: outdoor temperature: 40 ℃; temperature in vehicle cabin: 24 ℃; wind speed: 0.2m/s.
Q Vehicle body ＝kF(t m -t i )
Wherein, the comprehensive heat transfer coefficient of each part of the k-car body is obtained, and k=4.8W/m is taken by referring to other data 2 ·K；t m -an equivalent temperature of the body surface; t is t i -air temperature in the vehicle cabin;
wherein t is 0 -an outdoor temperature; i G -direct intensity of the sun; i S -the scattering intensity of the sun; epsilon-surface absorption coefficient, which is related to the color of the body, epsilon [0,1 ]]Epsilon=0.9;
the convective heat transfer coefficient of α -outdoor air, α=1.163 (12×v 0.5 +4), v is the wind speed outside the vehicle, and the vehicle taking speedDegree 0.2m/s, so α=10.9W/m 2 ·K。
(1) Roof of vehicle
Surface integrated temperature
Q Roof of vehicle ＝kF(t m -t i )＝4.8×1.18×(103－24)＝447.4(W)。
(2) Vehicle floor thermal load
The temperature of the ground surface is 60 ℃, the heat radiation of the ground surface is calculated, and I is taken Bottom plate ＝200W，
Therefore, it is
Q Bottom ＝kF△t＝4.8×3.35×(51.5－24)＝442.2(W)。
(3) Engine compartment heat transfer
Referring to other data, the surface temperature of the dash panel of the engine compartment is 60 ℃, so
Q Front wall ＝kF△t＝4.8×0.95×(60-24)＝164.16(W)。
In summary, the heat transfer amount of the whole vehicle body is Q Vehicle body ＝Q Roof of vehicle +Q Bottom +Q Front wall 447.4+442.2+164.16= 1053.76 (W). Therefore, the vehicle body shell is made of the phase-change heat storage material, so that the temperature regulation and control effect in the vehicle room can be further improved, the use of the vehicle-mounted air conditioner can be greatly reduced or the vehicle-mounted air conditioner can be completely replaced, and the energy consumption and cost of the vehicle-mounted air conditioner are obviously reduced.
According to an embodiment of the present invention, the vehicle compartment may include at least one selected from a cockpit, a passenger compartment, or an operation compartment according to a type of vehicle. For example, when the vehicle is a truck, the cabin interior temperature management system may be provided only for the cabin in order to improve the driving environment of the driver, and only the body case of the cabin portion may be selected as the phase change heat storage material case. For another example, when the vehicle is an automobile, in order to improve the riding environment of the driver and other passengers at the same time, a vehicle interior temperature management system may be provided for both the cabin and the passenger compartment, wherein the cabin and the passenger compartment may be integrally communicated, and in this case, it may be preferable to use a phase change heat storage material housing for the entire body housing of the vehicle. For another example, when the vehicle is a mechanical engineering vehicle, a vehicle interior temperature management system may be provided for the operation room to improve the operation environment of the operator, and at least the vehicle body casing of the operation room portion may be a phase change heat storage material casing.
According to an embodiment of the present invention, it is understood with reference to fig. 5 that the phase change heat storage material housing may include a metal foam skeleton 14 and a phase change heat storage material 15 filled in the metal foam skeleton.

According to some embodiments of the present invention, the foam metal skeleton 14 may be foam aluminum, the phase-change heat storage material 15 may be paraffin, and the foam aluminum has lighter weight, which is more beneficial to reducing the whole vehicle quality and reducing the vehicle driving energy consumption; the phase change of the paraffin is about 45 ℃, so that good heat absorption and heat release effects can be achieved based on the melting and solidification of the paraffin, and particularly, as understood by referring to fig. 2, heat damage is generated in high-temperature weather during solar illumination and automobile running, the paraffin filled in the foamed aluminum melts and absorbs heat, the heat of the melted paraffin is taken away by a heat exchange working medium (such as heat exchange liquid) in a foamed aluminum heat exchange tube to solidify the paraffin, and the heat exchange liquid taking away the heat enters a heat dissipation device to cool, so that the normal circulation of cooling liquid is ensured by a conveying pump; referring to fig. 3, it is understood that paraffin filled in the foamed aluminum is solid in low-temperature weather, the paraffin is melted by the heat exchange working medium heated in the foamed aluminum heat exchange tube, and the liquid paraffin is solidified in low-temperature environment to release heat. The heat exchange working medium in the foam aluminum heat exchange tube enters a heating device (such as an engine) to be heated again, and the normal circulation of the cooling liquid is ensured by a conveying pump.
It will be appreciated that, according to the embodiments of the present invention, the specific type of heat exchange medium used in the present invention is not particularly limited, and those skilled in the art can flexibly select, for example, a heat exchange fluid such as water according to actual needs.
According to an embodiment of the present invention, it is understood with reference to fig. 6 that the heat exchange tube 11 may include a plurality of sub heat exchange tubes arranged at intervals, the plurality of sub heat exchange tubes may be arranged in series and/or in parallel, and the plurality of sub heat exchange tubes may share one first heat exchange medium inlet 12 and one first heat exchange medium outlet 13. Wherein, set up a plurality of sub heat exchange tubes and be favorable to improving the homogeneity to the interior temperature regulation and control of car more.
