Abstract
The utility model discloses a front end cover of a heat exchanger which is made of engineering plastics. The front end cover is made of engineering plastics, and mainly comprises a bolt hole, a transverse reinforcement rib, a longitudinal reinforcement rib, a heat transfer medium inlet and a heat transfer medium outlet which are uniformly distributed on the outer circumference of the front end cover. The front end cover provided by the utility model adopts the transverse reinforcement rib and longitudinal reinforcement rib design in the structure, the intensity and rigidity of the end cover are strengthened without adding the wall thickness of an end face wall, the material is saved, meanwhile, the product weight is lightened, and the economic benefits are improved. The front end cover provided by the utility model has the advantages that the front end cover and a seawater source heat exchanger are matched and used, sea water corrosion proof engineering plastics are adopted, compared with the existing yellow brass end cover adopted in the industry, the installation weight is light, the sea water corrosion proof ability is strong, and the installation and dismantling are convenient; and the front end cover is matched with a freshwater source heat exchanger in use, compared with the existing graphite cast iron end cover utilized in the industry, and the front end cover completely solves the problem that the end cover is easy to freeze off and crack in winter.
Description
Technical field
The utility model relates to a kind of end cap of heat exchanger, especially a kind of drive end bearing bracket of case tube heat exchanger.
Background technology
At present, the drive end bearing bracket of known case tube heat exchanger generally is made of metal, and in order to strengthen its intensity and rigidity, drive end bearing bracket is often more thick and heavy, and processing cost is also very high, and complicated structural design also makes the installation of drive end bearing bracket very inconvenient.Some case tube heat exchanger end cap is corroded in order to prevent, can use some precious metals, and this will strengthen use cost, the waste ore resource of case tube heat exchanger end cap.
Summary of the invention
The purpose of this utility model is to provide a kind of case tube heat exchanger drive end bearing bracket of being made by engineering plastics, this drive end bearing bracket not only can strengthen intensity and the rigidity of drive end bearing bracket under the prerequisite that does not increase the end cap wall thickness, alleviate product weight, and employed engineering plastics have, and the seawater corrosion resistance ability is strong, low temperature environment is difficult for the freezing characteristics that crack.
The utility model is achieved like this, described drive end bearing bracket is made by engineering plastics, comprises bolt hole, cross reinforcing, waling, heat transferring medium import and heat transferring medium outlet.Described bolt hole evenly distributes along the excircle of described drive end bearing bracket; Described cross reinforcing is rectangular column structure, invests the outer surface of drive end bearing bracket, and length extends to circle centre position from the edge of end cap; Described waling is rectangular column structure, invests the outer surface of drive end bearing bracket, and direction is vertical with cross reinforcing, and length extends to the end cap edge; Described heat transferring medium import and heat transferring medium outlet are distributed in the cross reinforcing both sides.
Technique scheme can also further be optimized, and as preferably, the inside of bolt hole is carried out metric thread and processed, and can adopt screw bolt and nut that end cap is connected with the case tube heat exchanger housing.
As preferably, add out the frictional force when modular angle ejects to lower the demoulding on the both sides of reinforcement.
As preferably, the position that reinforcement and bottom head covers are joined is added with fillet with the concentrated phenomenon that eliminates stress.
As preferably, heat transferring medium import and heat transferring medium outlet are circle, and its size can be determined according to the size of heat exchange coil.
The utility model has the following advantages:
1, structurally adopts the design of cross reinforcing and waling, not only increase intensity and the rigidity of drive end bearing bracket, and alleviated weight, saved material, improved economic benefit, reinforcement can also overcome the twisted distortion of product that the unbalanced stress that brings because of Wall-Thickness Difference causes.
When 2, described drive end bearing bracket and source of seawater heat exchanger support the use, adopt the engineering plastics of seawater corrosion resistance, compare the brass end cap that adopts at present of the same trade and have the advantages that weight of equipment is light, the seawater corrosion resistance ability is superior, be convenient to installation and removal, greatly reduce the utilization rate to non-ferrous metal, processing cost is effectively reduced; When supporting the use with the freshwater source heat exchanger, compare the graphite cast iron end cap that uses at present of the same trade, thoroughly solved the easy freezing problem that cracks of end cap in winter.
Description of drawings
Fig. 1 is front elevation of the present utility model;
Fig. 2 is M-M directional profile figure among Fig. 1;
Fig. 3 is back view of the present utility model.
Wherein: 1, equally distributed bolt hole; 2, cross reinforcing; 3, waling; 4, heat transferring medium import; 5, heat transferring medium outlet.
The specific embodiment
Below in conjunction with accompanying drawing, by embodiment the utility model is described further.
The drive end bearing bracket of case tube heat exchanger as shown in figures 1 and 3 comprises equally distributed bolt hole 1, cross reinforcing 2, waling 3, heat transferring medium import 4, heat transferring medium outlet 5.
The utility model is through air pressure 1MPa, and pressurize detected in 20 minutes, and sample surfaces is without obviously being out of shape and crackle; Detect through tension weight churning, test height 1m, test weight 500g impacts 3 times, and sample surfaces satisfies the requirement of heat exchanger end cap without damaged crackle aspect intensity.
