The heat collector 110 includes a mounting frame 111 and a plurality of vacuum tubes 112, the plurality of vacuum tubes 112 are mounted on the mounting frame 111, and two ends of each vacuum tube 112 are respectively communicated with the air outlet channel and the air return channel. The vacuum tubes 112 are uniformly distributed in two rows and mounted on the mounting frame 111, and the distance between any two adjacent vacuum tubes 112 in the same row is the same.

In this embodiment, through set up air-out passageway and return air passageway on heat collector 110, when using solar energy heater unit 100 to heat, inhale heat collector 110 with indoor cold air through the return air passageway, heat collector 110 heats the cold air, and the hot-air after the heating passes through the fan and carries indoorly, to indoor transport hot-air when taking out indoor air conditioning, can improve the speed that solar energy heater unit 100 heaied up to indoor temperature for indoor intensification.

By providing the vacuum tube 112 to heat the cool air, the vacuum tube 112 heats faster than a solar panel, thereby increasing the indoor temperature rise rate. Be two rows with a plurality of vacuum tubes 112 and install in mounting bracket 111, use a plurality of vacuum tubes 112, can heat a large amount of cold air simultaneously to a plurality of vacuum tubes 112 shunt inspiratory cold air, and each vacuum tube 112 heats the small part in a large amount of cold air, and then makes cold air programming rate fast. The distance between any two adjacent vacuum tubes 112 in the same column is the same, so that the cold air distribution is more uniform, excessive cold air in one vacuum tube 112 is avoided, and other vacuum tubes 112 are not filled with air, so that the utilization rate of the vacuum tubes 112 is improved.

In detail, a plurality of vacuum tubes 112 are detachably mounted to the mounting frame 111, which is more convenient in transporting or carrying the heater unit. Meanwhile, when a certain vacuum tube 112 has a problem, the vacuum tube can be replaced in time, and other vacuum tubes 112 do not need to be taken down, so that the vacuum tube 112 is more convenient to replace and maintain. The air return channels are two and are respectively located on two opposite sides of the mounting frame 111, the air outlet channel is one, the air outlet channel is located between the two air return channels, and the air outlet channel is parallel to the two air return channels.
