The invention discloses a design method for solving the inconsistency of highlights on the profile of a vehicle body. It includes the following steps: find out the main shape features of the front view of the car body; find out the main shape features of the front view of the car body; find out the transition features between the two views of the car body; The front view analyzes the highlight trend of the main modeling features; the light source is viewed from the X, Y, and Z directions of the body coordinates to view the profile highlights corresponding to the front view and the front side view, and the highlight is required to be consistent with the trend of the feature line, and the highlight arc Full, with the two dimensions of highlight convex and concave as the judging standard, no convex and concave undulations, only single convex and single concave distribution, high light density and uniformity, smooth highlights between parts without sudden changes. According to the invention, the profile deviation caused by profile highlight adjustment is very small, which will not lead to changes in the internal structure of parts, and will not cause changes in engineering layout and structure.

The invention relates to a thermosiphon hot water system used for recovering exhaust energy of a domestic air conditioner, and belongs to the technical field of refrigerating system waste heat recovery. Based on the thermotube principle, a large amount of latent heat of vaporization released during phase change of a low-boiling working medium is utilized to obtain high heat exchange efficiency, and waste heat recovery effect is obvious. Temperature of a compressor exhaust pipeline and load of a condenser can be lowered, and performance coefficient of an original refrigerating system is increased; hot water is accumulated in a water tank in a heat accumulation mode, different living needs are met, and the problem that ordinary families use air conditioners and hot water at different time is solved. The thermosiphon hot water system is simple in structure and convenient to mount and dismount, when the domestic air conditioner is modified, the structure of the original refrigerating system is unchanged, and no impact on security and stability of the system is caused. Since no engineering change is made on the original refrigerating system, mounting cost is low, investment payoff period is short, and convenience is brought to popularization and application.

The invention provides an LED (Light Emitting Diode) lamp (100) which has both heat radiating function and electromagnetic shielding function. The LED lamp (100) comprises a shell (6) and an LED light source assembly which comprises an LED light source (4), a drive circuit board (9) and an LED light source switch control device. A heat radiating device which separates the LED light source (4) from the drive circuit board (9) is arranged in the LED lamp (1000) and comprises a main heat radiating board (1) and an auxiliary heat radiating board (2), and the auxiliary heat radiating board is attached to the main heat radiating board (1). Since the main heat radiating board (1) and the auxiliary heat radiating board (2) can effectively and reliably cool the drive circuit board (9) and the main heat radiating board (1) can cover the drive circuit board (9) effectively, therefore, the LED light source assembly achieves reliable electromagnetic shielding function and guarantees the stable working of the LED light source.

The invention relates to a water heater accessory system with the functions of drying and blowing hot wind, which mainly comprises an electronic control valve for drying, an electronic control valve for switching hot wind and hot water, a magnet for adsorption, positive temperature coefficient (PTC) ceramic heating elements, a thermostatic heater, a fan, a drier, a bracket, an electric control unit, and the like, wherein the fan, the PTC ceramic heating elements, and the like form the thermostatic heater; the PTC ceramic heating elements comprise a plurality of layers; the thermostatic heateris connected with the drier through the electronic control valve for drying; and the thermostatic heater and a water heater are connected with a shower nozzle through the electronic control valve forswitching hot wind and hot water.
