Abstract

The utility model relates to a device for supplying heating wind and cooling wind to passenger car. Now, the domestic coach bus has no air-conditioning equipment, so the passengers are suffered from cold and hot in winter and summer. In order to realize supplying heating wind and cooling wind without increasing energy consumption, the utility model is designed with a two-use device. In winter, the device is connected to the engine exhaust pipe to supply heating wind to carriage by making use of the rest heat; in summer, the device is injected with refrigerant or cooling liquid to supply cooling wind to carriage by conduction function to obtain cooling effect. The device mainly comprises a tank body and a heat-collector composed of an outer tube and a heat collecting tube so the device has simple structure.

Description

Heating and cooling two-use device for passenger car

A kind ofly be related to the device that motor passenger vehicle provides warm braw and cold air.

Homemade long-distance bus does not generally all have air-conditioning or heating refrigeration equipment at present.Therefore in two seasons of summer in winter, the passenger is the hardship of bitter cold, heat extremely.Given this feelings are not increase the device that energy consumption realizes heat supply in winter, as 85205756 patents.This device only has simple function--and be heat supply in winter.The purpose of this utility model be the design a kind of utilize engine exhaust heat realize heat supply in winter and summer transporting cold wind dual-purpose apparatus.

This device mainly contains a casing and a heating device constitutes.The heating device has a sealing two ends but respectively is shaped on the outer tube that (going out) gas interface is advanced in an exhaust, be shaped on a thermal-collecting tube in the pipe, this is managed and is welded with interior pipe not connected more than 5 in two closed ends, differ in interior pipe aperture, two ends, its big nose end is near outer tube exhaust intake interface, the purpose of this structure is to quicken exhaust velocity, improves efficiency of heat cycle.The thermal-arrest tube wall respectively is welded with one along the two ends of its section and advances (going out) gas port, for air inlet and output warm braw and cold air.This two pipe all passes outer tube and welds it.The heating device places among the casing, its exhaust advance on (going out) gas interface and the thermal-collecting tube advance (going out) gas port with pass casing and the welding fix it.The lid of casing is the venetian blind type structure, and bottom half is shaped on tapping valve.During use, this device is contained in passenger vehicle bottom and inserts among the freeing pipe, promptly the driving engine high-temperature gas of discharging is by this device.When running, be enhanced temperature through warmed-up thermal-collecting tube and be disposed in the railway carriage from the air of thermal-collecting tube admission port inspiration by air extractor duct, promptly this has realized the purpose for the passenger vehicle heating.Sometimes be quick pyrogenicity, also can open case lid to strengthen heat delivery surface.Summer, this device did not insert freeing pipe when using, and injected non-volatility refrigerant or refrigerant fluid in its casing, and outer tube is invaded not among liquid, because conduction can make temperature decline in the heating device.The passenger vehicle that runs is entered in the car by air extractor duct after adopting the cooling of cold (warming up) device from the admission port suck air, makes constantly to obtain being lower than the fresh and pleasantly cool air of temperature in the car, to separate the scorching hardship of passenger's heat.

The maximum characteristics of this device are the purposes that has reached the relieving summer-heat of enjoying the cool summer when having utilized exhaust heat to solve the heat supply in winter problem again, are at one stroke two.

The utility model proposes a kind of embodiment shown in the drawings, this figure is an apparatus structure longitudinal profile scheme drawing, wherein;

1--casing 2--venetian blind type case lid

3--outer tube 4--thermal-collecting tube

Pipe (this case is 7) 6--air extractor duct in the 5--

7--exhaust intake interface 8--admission port

The 9--valve 10--exhaust interface of giving vent to anger

The refrigerant fluid that this case is used is salt solution.

Claims

1, a kind ofly comprises a casing and a heating device, it is characterized in that by interior pipe, thermal-collecting tube, outer tube, advance the heating apparatus of formations such as (going out) gas port in the casing that is shaped on the venetian blind type case lid for motor passenger vehicle provides the device of warm braw and cold air.

2, as the said device of claim 1, it is characterized in that heating device outer tube osed top two ends respectively are welded with an exhaust and advance (going out) gas interface and pass the casing welding, the thermal-collecting tube of pipe in one of containing is welded with more than 5 in the osed top two ends in its pipe, all do not communicate between pipe and with thermal-collecting tube in each, interior pipe one stomidium footpath is greater than other stomidium footpath, and the two ends of thermal-arrest tubular axis section respectively are welded with one and advance (going out) gas port and pass outer tube and the casing welding.

3, as claim 1,2 said devices, it is characterized in that casing all is an osed top except that the venetian blind type case lid, bottom half one end is shaped on tapping valve.
