In the microwave heating unit, each split type fin is symmetrically welded with the heat exchange tube at four points through the side baffle.

In the microwave heating unit, the iron powder layer is respectively in close contact connection with the groove part of the split type fin and the heat exchange tube.

In the microwave heating unit, each heat exchange tube corresponds to more than two split fins, and a gap is reserved between every two adjacent split fins to form a split structure of the fins.

The utility model has the advantages and beneficial effects that:

1. the utility model relates to a rationally, simple structure, the heating process utilizes a small amount of electric energy to be the driving energy, and the excitation produces the high power microwave energy, converts microwave energy 100% into heat energy again to make it form the circulation, reach the purpose of heating. The utility model discloses mainly be applied to the heating of a family, daily need not to maintain, the operation cost is low, and is clean, environmental protection, power consumption are low, efficient, are applicable to places such as town and country family, office, hotel, indoor culture and planting and do the heating use.

2. The utility model discloses a fin increases the heat transfer area between heat exchange tube and the split type fin, improves heat transfer coefficient between heat exchange tube and the split type fin, and it is undulant to satisfy the user with the ability.

3. The utility model discloses heat transfer area increases the heat transfer capacity between multiplicable split type fin and the heat exchange tube. Meanwhile, the fins and the heat exchange tube are only welded by four points, so that the heat exchange tube and the fins are prevented from being damaged by overlarge thermal stress at the joint of the fins and the heat exchange tube, and the deflection deformation of the fins caused by overlarge temperature difference is also avoided.

Fig. 2 is an enlarged sectional view a-a in fig. 1.

In the figure, 1 is a split type fin; 11 groove portions; 12 a fin portion; 2, exchanging a heat pipe; 3, covering the cover; 4 side baffle plates; 5, iron powder layer; 6, a microwave head; 7 microwave heating chamber.

Detailed Description

The present invention will be explained in further detail below with reference to examples and drawings. However, these embodiments are not intended to limit the scope of the present invention, and all of them are within the scope of the basic idea of the present invention or essentially equivalent to the scope of the present invention.

As shown in fig. 1-2, the microwave heating unit of the present invention mainly comprises: split type fin 1, heat exchange tube 2, upper cover 3, side shield 4, iron powder layer 5, microwave head 6, microwave heating chamber 7 etc. specific structure as follows:

split type fin 1 is including being located middle groove part 11 and the fin part 12 that is located both sides, groove part 11 and fin part 12 connection structure as an organic whole, groove part 11 is corresponding with heat exchange tube 2 through the cambered surface of inboard, leave the clearance between heat exchange tube 2 and the groove part 11, and fill iron powder layer 5 between heat exchange tube 2 and groove part 11, the both sides of groove part 11 set up side shield 4 relatively, the top of groove part 11 sets up upper cover 3, iron powder layer 5 is located side shield 4, the recess that upper cover 3 formed. Each split type fin 1 is welded with the heat exchange tube 2 in four-point symmetry through the side baffle 4, a microwave heating chamber 7 is arranged on the side face where each split type fin 1 and the heat exchange tube 2 are located, a microwave head 6 is installed in the middle of the inner side of the microwave heating chamber 7, the microwave head 6 corresponds to the heat exchange tube 2, and the heat exchange tube 2 and circulating water in the heat exchange tube 2 can be heated.

The iron powder layer 5 is respectively connected with the groove part 11 of the split type fin 1 and the heat exchange tube 2 in close contact, and the iron powder layer 5 prevents the heat exchange tube 2 from being in virtual connection with the groove part 11, so that the heat transfer effect is ensured. Each heat exchange tube 2 corresponds to more than two split fins 1, and a gap is reserved between every two adjacent split fins 1 to form a split structure of the fins.

During the use, will the utility model discloses microwave heating unit installs on heating equipment's circulating line, directly through the circulating water heating of microwave heating unit in to the heat-transfer pipe, need not with the outside circulation pipeline connection in heating space, the circulating water only circulates in the space that needs the heating, has avoided the calorific loss, the circulating water loss of current external circulation pipeline, very big saving heating cost.
