Description
Technical field
This utility model belongs to engine art, is specifically related to a kind of embedded pressure limiting engine exhaust heater heated by waste heat.
Background technology
Engine exhaust heater heated by waste heat uses tubing heat exchanger mostly at present, and the heat exchanger heat utilization efficiency of this structure is inadequate, causes the waste of waste heat；And this heat exchanger is it is possible that air chamber hypertonia damages the problem of air chamber, the most safe and reliable during use.
Utility model content
The purpose of this utility model is to provide the embedded pressure limiting engine exhaust heater heated by waste heat that a kind of heat utilization efficiency is high, use safety.
The technical solution adopted in the utility model is a kind of embedded pressure limiting engine exhaust heater heated by waste heat, including heater housing and the heater inner shell of hollow structure on its interior of hollow structure；Described heater inner shell upper end is provided with gas outlet, and lower end is provided with air inlet；Described heater housing top is provided with outlet, and bottom is provided with water inlet；It is embedded with fin on heater inner shell；Fin is simultaneously to heater inner housing inner and outside extension, and is arranged at inside heater housing.
Further, described fin has multi-disc, is uniformly embedded on heater inner shell.
Further, described heater inner shell upper end is provided with pressure limiting valve near position, gas outlet.
Further, described heater inner shell is hollow circular cylinder structure, and fin is arranged along heater inner shell radial direction and is perpendicular to heater inner shell lower surface.
Further, described pressure limiting valve is hollow circular cylinder knot, and lower surface is provided with the second passage for connecting heater inner shell, and upper surface is provided with the first passage；It is provided with the second baffle for blocking the second passage in pressure limiting valve, inside it, is additionally provided with the first baffle plate being connected to block the first passage by spring and second baffle.
The beneficial effects of the utility model are:
(1) fin part is stretched into heater inner housing inner by this utility model, adds the heat transfer area of heat convection, improves heat exchange efficiency；
(2) this utility model heater inner shell upper end is provided with pressure limiting valve, it is to avoid because of in heater inner shell hypertonia and damage heater inner shell.

Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As Figure 1-3, a kind of embedded pressure limiting engine exhaust heater heated by waste heat, including heater housing 2 and the heater inner shell 1 of hollow structure on its interior of hollow structure；Described heater inner shell 1 upper end is provided with gas outlet 3, and lower end is provided with air inlet 4；Described heater housing 2 top is provided with outlet 5, and bottom is provided with water inlet 6；Fin 8 it is embedded with on heater inner shell 1；Fin 8 is simultaneously to the inside and outside extension of heater inner shell 1, and it is internal to be arranged at heater housing 2.
Further, described fin 8 has multi-disc, is uniformly embedded on heater inner shell 1.
Further, described heater inner shell 2 upper end is provided with pressure limiting valve 7 near position, gas outlet 3.
Further, described heater inner shell 1 is hollow circular cylinder structure, and fin 8 is arranged along heater inner shell 1 radial direction and is perpendicular to heater inner shell 1 lower surface.
During use, the waste gas of electromotor enters inside it from the air inlet 4 being positioned at heater inner shell 1, flow through whole heater inner shell 1 internal, flow process transfers heat to fin 8 and heater inner shell 1 wall, finally flows out from the gas outlet 3 being positioned at heater inner shell 1；Meanwhile, cold water flows into inside it from the water inlet 6 being positioned at heater housing 2 bottom；Between heater inner shell 1 and heater housing 2, by absorbing heat between fin 8 and heater inner shell 1 wall, finally the water after heat absorption flows out from the outlet 5 being positioned at heater housing 2 top.
Further, described pressure limiting valve 7 is tied for hollow circular cylinder, and lower surface is provided with the second passage 74 for connecting heater inner shell 1, and upper surface is provided with the first passage 73；It is provided with the second baffle 72 for blocking the second passage 74 in pressure limiting valve 7, inside it, is additionally provided with the first baffle plate 71 being connected to block the first passage 73 by spring 75 and second baffle 72.
As shown in Figure 4, heater inner shell 1 upper end is provided with pressure limiting valve 7, and when heater inner shell 2 internal gas pressure is relatively low, pressure limiting valve 7 does not works；When heater inner shell 1 internal gas pressure is higher, gas can will be located in bottom pressure limiting valve 7, pushes open for blocking the second baffle 72 of the second passage 74, and gas enters in pressure limiting valve 7 by the second passage 74, is discharged by first passage 73 at pressure limiting valve 7 top；Thus ensure that the stable gas pressure within heater inner shell 1.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
