Internal suction type heat-pipe heating radiator

The utility model relates to an internal absorbing type heat tube heating radiator, which comprises a horizontally placed heat tube with two ends closed, and the inside of the heat tube is provided with a heat absorbing tube along the axial direction, and the two ends of the heat absorbing extend to the two ends of the heat tube. The outside surface of the horizontally placed heat tube is communicated with a heat tube in an upright and horizontal or inclined crossing manner. The outside surface of the horizontally placed heat tube is provided with two or more than two standing heat tubes communicated with the horizontally placed heat tube, and the upper end of each standing heat tube is communicated with the upper horizontally placed heat tube, thereby, the horizontally placed heat tubes of the upper and lower are all communicated with the standing heat tube, and the area of the outside surface of each heat tube is the heat emission area, thereby reaching the aim of increasing the heat emission area of the heat tube. The utility model has high heat efficiency and wide using, which can be made to the electrical heater with low power or directly used instead of the normal heating radiator.
