Fig. 4 is that the enforcement of the distortion tubing heat exchanger involved by embodiment of the present utility model is prevented
The explanatory diagram of the scope of erosion protective layer.
As shown in Figure 4, the both ends assembling pipe 10 at distortion tubing heat exchanger 1 are set with
Corrosion protection layer forming range 5.At this, the both ends of so-called assembling pipe 10 are: will be relative to water
Pipe 2 winding refrigerant pipe 3 winding side, top position as this assembling pipe 10 one end,
Using the position of the winding end side of refrigerant pipe 3 that winds relative to water pipe 2 as this assembling pipe 10
The other end.
Fig. 5 is the reality representing the distortion tubing heat exchanger involved by embodiment of the present utility model
Execute the state after corrosion protection layer, along the sectional view in pipe axis direction.
As shown in FIG. 4 and 5, distort tubing heat exchanger 1, assemble pipe 10 being set in
The corrosion protection layer forming range 5 at both ends implements the corrosion protection layer 6 with thermal insulation.That is,
Corrosion protection layer 6 is set to the outer surface to the both ends assembling pipe 10 covered by soldering-tin layer 4
Cover.
It follows that action is illustrated.
In the distortion tubing heat exchanger 1 so constituted, owing to corrosion protection layer 6 is to assembling pipe
The outer surface of the water pipe 2 at the both ends of 10, refrigerant pipe 3 and soldering-tin layer 4 covers, because of
This can protect refrigerant pipe 3 (copper pipe) from from dew, the impact of corrosive atmosphere.
It is further possible to utilize the corrosion protection layer 6 both ends (phase to distortion tubing heat exchanger 1
When in the both ends assembling pipe 10) protect, thus from the shadow from outside water stain grade
Ring.Now, as the scope of protection, pipe 10 is i.e. being assembled from distortion tubing heat exchanger 1
Two ends are played and are protected, preferably 10% in the range of minimum the 5% of the total length assembling pipe 10
In the range of protect.
It is as noted previously, as the end utilizing corrosion protection layer 6 to protect distortion tubing heat exchanger 1
The outer surface in portion, therefore, it is possible to the corrosion of suppression refrigerant pipe 3 (copper pipe).
Further, since corrosion protection layer 6 has thermal insulation, heat radiation when therefore reducing heat exchange is damaged
Lose, thus improve heat exchange performance.
Here, as the material of corrosion protection layer 6, such as contain the heat insulation painting of the ceramic bead of hollow
Material is effective.Compared with the insulating moulding coating of the ceramic bead not containing hollow, for containing hollow
In the case of the insulating moulding coating of ceramic bead, heat-proof quality improves.
It addition, at the product such as off-premises station that distortion tubing heat exchanger 1 is equipped on such as air conditioner
Time, it is possible to assemble when after being packed by package members such as the casees of expanded polystyrene (EPS).
Therefore corrosion protection layer 6 is the thermal conductivity of the package member with packaging distortion tubing heat exchanger 1
The material of following thermal conductivity, keeping in the winter time, prevents condensation aspect during carrying preferred.?
In the case of using expanded polystyrene (EPS) as package member, as long as corrosion protection layer 6 is general
The material of the thermal conductivity 0.04 [W/mK] of expanded polystyrene (EPS) thermal conductivity below.
It addition, as the material of corrosion protection layer 6, except it is stated that the ceramic bead containing hollow
Insulating moulding coating beyond, such as can also use the heat-shrinkable tube that heat-proof quality is high.Even if so
In the case of, it is also possible to obtain with it is stated that the insulating moulding coating containing ceramic bead as effect.
With use coating situation compared with, do not have coating disperse wait for use heat-shrinkable tube advantage, because of
This improves the maintainability of production equipment, workability.
