Abstract
The utility model relates to a heat exchanging element which is used in a cold store, specifically a heat exchanger for the cold store. The heat exchanger solves the problem of defrosting the external surface of the heat exchanger which is used for the cold store in the prior art. The structure of the heat exchanger consists of a refrigeration pipe for the flow of a refrigerating medium, external rib plates connected at both sides of the refrigeration pipe, wherein a small arc face section and a judged section are arranged on the inner wall of the refrigeration pipe. Compared with the prior art, a plurality of designs for strengthening the pressure bearing capacity of the refrigeration pipe are adopted, so as to effectively improve the pressure bearing capacity of the refrigeration pipe, therefore steam defrosting is achieved. Moreover, the refrigerating rate is improved and the operating cost is lowered.
Description
Technical field
The utility model relates to the heat exchange elements that a kind of freezer uses, and is specially a kind of cold storage heat exchanger.
Background technology
The heat exchange elements refrigeration that existing freezer uses is more satisfactory, is using a period of time rear surface meeting frosting, and the existence of frost can have a strong impact on the efficient of heat exchange, so defrosting in good time.And directly use the steam defrosting, but because its inner pressure-bearing is less, safety problem takes place easily, so can only adopt the electrical heating defrosting, reduced the security when using, defrosting simultaneously not exclusively makes the refrigerating efficiency step-down, and operating cost increases.
Summary of the invention
The utility model is for the heat exchange elements outer surface defrosting problem that solves the freezer that exists in the prior art and use and a kind of cold storage heat exchanger is provided.
The utility model is realized by following technical scheme, and a kind of cold storage heat exchanger comprises the refrigerator pipes of the refrigerant that flows, and is connected the outer floor of refrigerator pipes both sides, is provided with roundlet cambered surface section and profile of tooth section at the refrigerator pipes inwall.This design can make the anti-pressure ability of refrigerator pipes increase, and can also improve the disturbance in the flow of refrigerant process, increases in order to flow velocity.When needs defrost to the refrigerator pipes outer surface, can in refrigerator pipes, feed the steam of HTHP, and replace using electrically heated Defrost mode.
Roundlet cambered surface section and profile of tooth section have two sections respectively, and the profile of tooth section is positioned at the both sides adjacent with outer floor of refrigerator pipes, and roundlet cambered surface section is positioned at the refrigerator pipes upper and lower sides.It is more favourable that this structure can make external fin plate and cold-producing medium pass through profile of tooth section heat-shift.
Also be provided with ribs outside on the floor, the outward flange of outer floor is provided with circular anti-cutting safety belt.Refrigerator pipes and outside the floor junction be provided with reinforcing band.
Compared with prior art, the utility model has used the design of bearing strength in the multiple reinforcement refrigerator pipes, can effectively improve the pressure-bearing property of refrigerator pipes, and the steam defrosting is achieved.Improve refrigerating efficiency, reduced operating cost.
Description of drawings

The specific embodiment
As schematically shown in Figure 1, a kind of cold storage heat exchanger comprises the refrigerator pipes 5 of the refrigerant that flows, and is connected the outer floor 3 of refrigerator pipes 5 both sides, is provided with roundlet cambered surface section 6 and profile of tooth section 7 at refrigerator pipes 5 inwalls.Roundlet cambered surface section 6 and profile of tooth section 7 have two sections respectively, the both sides that floor that profile of tooth section 7 is positioned at refrigerator pipes 5 and outer 3 is adjacent, and roundlet cambered surface section 6 is positioned at refrigerator pipes 5 upper and lower sides.Also be provided with ribs 2 on the floor 3 outside, the outward flange of outer floor 3 is provided with circular anti-cutting safety belt 1.Both can increase its rigidity, but the staff that prevents of maximum intensity scratches again.
Refrigerator pipes 5 and outside floor 3 junctions be provided with reinforcing band 4.
More than all members can use the method for monolithic extruded moulding to make its natural fusion together.
