Detailed Description
The invention will be further illustrated by means of specific embodiments in the following description with reference to the accompanying drawings:
referring to fig. 1 and 2, a temperature control device for an ecological greenhouse comprises a greenhouse planting area, a greenhouse internal heat dissipation unit 1 and an external heat generation mechanism 2, wherein the greenhouse internal heat dissipation unit 1 is arranged on two sides of the greenhouse planting area in pairs respectively, the external heat generation mechanism 2 is matched with the greenhouse internal heat dissipation unit 1, the greenhouse internal heat dissipation unit 1 comprises a heat dissipation base 11, a heat dissipation pipe 12 arranged on the heat dissipation base 11, a first heat preservation water tank 13 and a second heat preservation water tank 14 which are respectively communicated with two ends of the heat dissipation pipe 12, and a fan 15 which is arranged on the side of the heat dissipation base 11 and faces the heat dissipation pipe 12, a greenhouse internal circulation water pipe 16 is arranged between the second heat preservation water tanks 14, and the; the off-shed heat generating mechanism comprises a water heater 21, an off-shed circulating water pipe 22 with one end connected to the water heater 21 and the other end connected to the first heat-preserving water tank 13, and a water pump 23 arranged on the off-shed circulating water pipe 22. The circulating water pipe 22 outside the shed is provided with a flow control valve 26. The water pump 23 is also connected to a drain pipe 27. The water heater 21 is provided with a temperature control electric cabinet 24, the heat dissipation base 11 is provided with a temperature sensor 25, and the temperature sensor 25 is connected with the temperature control electric cabinet 24.
The heat dissipation base 11 is provided with an outer mounting inclined plane 111, the outer mounting inclined plane 111 is inclined upward and toward the planting area in the greenhouse, and the heat dissipation pipe 12 is arranged on the outer mounting inclined plane 111.
